BACKGROUND: Some studies indicated that implant failures are commonly concentrated in few patients. PURPOSE: To identify and analyze cluster behavior of dental implant failures among subjects of a retrospective study. MATERIALS AND METHODS: This retrospective study included patients receiving at least three implants only. Patients presenting at least three implant failures were classified as presenting a cluster behavior. Univariate and multivariate logistic regression models and generalized estimating equations analysis evaluated the effect of explanatory variables on the cluster behavior. RESULTS: There were 1406 patients with three or more implants (8337 implants, 592 failures). Sixty-seven (4.77%) patients presented cluster behavior, with 56.8% of all implant failures. The intake of antidepressants and bruxism were identified as potential negative factors exerting a statistically significant influence on a cluster behavior at the patient-level. The negative factors at the implant-level were turned implants, short implants, poor bone quality, age of the patient, the intake of medicaments to reduce the acid gastric production, smoking, and bruxism. CONCLUSIONS: A cluster pattern among patients with implant failure is highly probable. Factors of interest as predictors for implant failures could be a number of systemic and local factors, although a direct causal relationship cannot be ascertained.

Immediate loading of four implants (BTLock ®) in the maxilla and provisional restoration with guidesurgery (SimPlant, Materialise ®): case report. The severe atrophy of the jaws are a challenging therapeutic problem, since the increase in bone is necessary to allow the placement of a sufficient number of implants. Combining immediate functionalization with the concept of guided surgery they combine the advantages offered by the innovative surgical and prosthetic implant technique (All-on-Four ®) with those of computer-assisted planning in cases of severe bone atrophy. The method used in this case report, combines these two concepts in a surgical and prosthetic protocol safe and effective for the immediate function of 4 implants to support a fixed prosthesis in completely edentulous subjects. The integration of technology with immediate function with the concept of computer-guided surgery for implant placement and rehabilitation of completely edentulous jaws is now a predictable treatment modality with implant survival comparable to the traditional protocols.

This study evaluated the efficacy of replacing single missing teeth in the posterior quadrants of the maxilla and/or mandible with an implant-supported dental prosthesis. Material and methods: Three scientific literature databases-Medline (Pubmed), Ovid Medline and Cochrane Central Register of Controlled Trials (CENTRAL)-were used to perform a search of publications over a period from 1985 to 2014. One hundred and forty one (141) articles were reviewed; 36 articles met the inclusion criteria and were included in the final review. Results: The survival rates, success rates and mean bone loss for immediate implant placement were 96.9%, 100% and 0.85 mm, respectively. The survival rates, success rates and mean bone loss for delayed implant placement were 96.8%, 94.1% and 0.55 mm respectively. The survival rate, success rate and the mean bone loss in studies comparing immediate versus delayed implant placement showed 96.8% and 96.3%, 85.8% and 93.3%, and 0.57 ± 0.57 mm and 0.55 ± 0.37 mm, respectively. Conclusion: The prognosis for single molar implants provides a viable treatment option for replacing a single missing tooth in the posterior quadrants of the maxilla and mandible. There does not appear to be a significant difference in the survival rates of immediately placed implants compared with delayed implant placement. However, the success rates were slightly higher with delayed loading protocols than immediate loading protocols.

Dental school graduates have many options following graduation. Many are pursuing additional education and training by doing a residency program. As more graduates consider this career path, these programs have become more competitive. This study evaluates the competitiveness of match programs in dental residency programs by assessing data over a 9-year period for programs in the National Matching Service. The number of applicants participating in the match, number of positions offered, number of positions filled, and number of positions unfilled were analyzed for General Practice Residency (GPR), Advanced Education in General Dentistry (AEGD), Oral Maxillofacial Surgery (OMS), Pediatric Dentistry (PED), Orthodontics (ORTHO) and Dental Anesthesiology (ANES). The result has been an overall increase in number of applicants for these programs. Based on positions offered, ORTHO, PED, and OMS are the most competitive programs. PED programs were the most competitive due to the increase in applicants and relatively unchanged available positions.

Implant dentistry was not a part of the dental school curriculum
for the vast majority of dentists in practice. This is why so many mistakes are made. Only now are dental schools starting to incorporate adequate training in implantology. Many dentists are more concerned with saving money by cuttingcorners or performing a procedure too quickly. Here are several factors that can contribute to dental implant mistakes.

Dental implantology is a traditional approach offered to fully or partially edentulous patients. Successful placing of implants needs specialized skill sets and expertise in order to achieve their viability. 3-D printing along with digital technology have made significant improvements to rate of success and have transformed work process and practices in standards of care in dental implants. Advanced-thinking clinicians and the dental laboratories have harnessed benefits of the digital technology for ensuring best outcomes for the patients as well as providing versatility and savings in time and cost. This paper discusses workflows by which a summarized surgical guide can be obtained.

Background: The marginal gap that may occur following implant installation in an extraction socket may be resolved by hard-tissue fill during healing. Objective: To study dimensional alterations of hard tissues that occur following tooth extraction and immediate placement of implants. Material and methods: Eighteen subjects with a total of 21 teeth scheduled for extraction were included. Following flap elevation and the removal of a tooth and implant installation, clinical measurements were made to characterize the dimension of the surrounding bone walls, as well as the marginal defect. No membranes or filler material was used. The flaps were subsequently replaced and secured with sutures in such a way that the healing cap of the implant was exposed to the oral environment. After 4 months of healing a re-entry procedure was performed and the clinical measurements were repeated. Results: Fifty-two marginal defects exceeding 3 mm were present at baseline: 21 at buccal, 17 at lingual/palatal, and 14 at approximal surfaces. At the re-entry eight defects exceeding 3.0 mm remained. During the 4 months of healing, the bone walls of the extraction underwent marked change. The horizontal resorption of the buccal bone dimension amounted to about 56%. The corresponding resorption of the lingual/ palatal bone was 30%. The vertical bone crest resorption amounted to 0.3 AE 0.6 mm (buccal), 0.6 AE 1.0 mm (lingual/palatal), 0.2 AE 0.7 mm (mesial), and 0.5 AE 0.9 mm (distal). Conclusion: The marginal gap that occurred between the metal rod and the bone tissue following implant installation in an extraction socket may predictably heal with new bone formation and defect resolution. The current results further documented that marginal gaps in buccal and palatal/lingual locations were resolved through new bone formation from the inside of the defects and substantial bone resorption from the outside of the ridge.

Abstract: The growing interest in minimally invasive implant placement and delivery of a prefabricated provisional
prosthesis immediately, thus minimizing “time to teeth,” has led to the development of numerous 3-dimensional
(3D) planning software programs. Given the enhancements associated with fully digital workflows, such as
better 3D soft-tissue visualization and virtual tooth rendering, computer-guided implant surgery and immediate
function has become an effective and reliable procedure. This article describes how modern implant planning
software programs provide a comprehensive digital platform that enables efficient interplay between the surgical
and restorative aspects of implant treatment. These new technologies that streamline the overall digital workflow
allow transformation of the digital wax-up into a personalized, CAD/CAM-milled provisional restoration. Thus,
collaborative digital workflows provide a novel approach for time-efficient delivery of a customized, screw-retained
provisional restoration on the day of implant surgery, resulting in improved predictability for immediate function in
the partially edentate patient.

The study highlights the corrosion behavior of untreated and treated tantalum with addition of trimanganese tetraoxide (Mn3O4) nanoparticles in simulated inflammatory media. The anodic layer was produced on pure tantalum by anodization in electrolytes composed of ammonium fluoride, ethylene glycol, and water. Nanoparticles were deposited uniformly on the surface of the anodized tantalum with the electrophoretic deposition (EPD) method. The results revealed that the anodic/EPD coating possessed more compact microstructure and higher bond strength than the anodic coating. Simulated inflammatory medium was based on phosphatebuffered saline with additions of H2O2 and HCl. Potentiodynamic polarization and electrochemical impedance spectroscopy studies showed that the anodic and Mn3O4 layers protected the tantalum from corroding in an acidic inflammatory condition. Finally, the corrosion protection mechanism of Mn3O4 NPs in inflammatory condition was presented.

The region of mandibular canine tooth is the most common location in which where occur lifethreatening
haemorrhages and cause airway obstruction. The aim of this study was to evaluate the
results of the insertion of a single implant in the mandibular canine region and the frequency of vascular and neuro-sensory complications associated with the procedure. Material and method: in 35 patients was carried out the insertion of a single implant in the canine mandibularregionn,
immediate temporary reconstruction of edentulous area and thereafter the achievement of a metal-ceramic crowns on implant. Results: the achievement of an osteotomy depth and the use of implants having a maximum 14 mm length has prevented the perforation of blood vessels and appearance
of profuse bleeding, and also the emergence of neurosensory disorders. Conclusions:The insertion of the implant in the mandibular canine region proved to be a procedure with a high
acceptance and satisfaction from the patients. If all the appropriate steps required for diagnosis
and treatment planning are taken and an adequate surgical protocol is followed, mandibular canine region is undoubtedly a safe zone for implant placement. Key words: single implant, canine mandibular region, vascular and neuro -sensory complications

Purpose: To introduce a digitally assisted technique to achieve the ideal soft and bone tissue interface for anatomic-driven pink free implant supported fixed prosthesis, and prefabricate an interim prosthesis to be used the day of the surgery as a prosthetic scaffold to condition the healing Methods: The digital assisted soft tissue sculpturing (DASS) technique allows the previsualization of the ideal soft and bone tissue interface and fabricate a computer aided design computer aided manufacturing (CAD-CAM) anatomic-driven pink free complete arch interim prosthesis for the immediate loading. Bone and soft tissue interface as well as the interim prosthesis design are performed in a segmented multiple standard tessellation language (STL) file embedding the bone anatomy, the intraoral surface anatomy (dental and soft tissue), the digital wax-up and the implant positioning. The interim prosthesis is used as a prosthetic scaffold to guide the soft and bone tissue surgical sculpturing and regeneration. Conclusions: The DASS technique is a predictable integrated digital workflow that simplifies the achievement of a scalloped tissue interface for pink free fixed implant prosthesis, reestablishing the mucosal dimension required for the protection of underlying bone while maintaining tissue health. The surgical sculpturing and maturation of the soft and bone tissue is driven and enhanced by the xenogeneic collagen matrix grafting and prosthetic scaffold effect of the digitally prefabricated interim prosthesis delivered the day of the surgery.

Introduction: Implant-supported fixed dental prosthesis is a standardized restoration method that is often used when an anterior single tooth is missing. However, when a titanium abutment is used in thin peri-implant mucosa in the anterior area, the metallic aspect can be visible through the mucosa. In order to offer an alternative solution to zirconia abutments and titanium abutments, the use of zirconia implant abutments connected to titanium base (Ti-base) has advanced to combine the advantages of the two kind of implant abutments. The aim of the present systematic review is to investigate the mechanical resistance of zirconia implant abutments connected to titanium bases and compare it to one-piece zirconia implant abutments and titanium implant abutments.

OBJECTIVE: To assess clinical and radiological performance of novel digital workflow integrating dynamic guided surgery, to streamline execution of implant placement, soft and bone tissue sculpturing, and immediate delivery of navigation guided complete-arch prosthesis.
MATERIALS AND METHODS: This proof of concept prospective single cohort study investigated 10 consecutive patients (three males, seven females; mean age 62.5 ± 8.9 years; range, 48-75) requiring at least one complete-arch fixed dental prostheses (FDP) in both jaws, treated between January and August 2019. Primary outcomes were implant and prosthetic success rates, surgical and prosthetic complications. Secondary outcomes were marginal bone loss (MBL), implant stability quotient (ISQ), periodontal parameters (plaque and bleeding indexes).
RESULTS: Sixty implants (32 NobelParallel TiUltra and 28 NobelActive TiUltra, Nobel Biocare) were placed and 14 complete-arch FDPs immediately loaded (mean follow-up 16.2 ± 1.7 months, 14-18). One implant failed and was immediately replaced. No other surgical or biological complications occurred, accounting for a cumulative success rate of 98.3%. No prosthetic complication occurred, leading to 100% prosthetic success rate. Mean ISQ at implant placement was 71 ± 2.8 (65-78). The mean MBL was -0.53 ± 0.28 mm (-0.22 to -1.12 mm). Plaque and bleeding scores were 14.4 ± 8.18 and 7.15 ± 4.4, respectively.
CONCLUSION: Within the limitations of this proof-of-concept dynamic navigation was effective to deliver in the planned coordinates both implants and prosthesis and guide bone and soft tissue sculpturing. Immediate loading of digitally prefabricated esthetically driven complete-arch FDP was facilitated, resulting in high implant and prosthetic success rates.
CLINICAL SIGNIFICANCE: The investigated digital workflow integrating dynamic navigation may overcome the difficulties related to immediate positioning and loading of digitally prefabricated complete-arch FDP. The navigation guided soft and bone tissues sculpturing, associated to xenogeneic collagen matrix grafting, represented a predictable technique to achieve the digitally planned interface, reestablishing the mucosal dimension required for the protection of underlying bone while maintaining tissue health.

Aim: The aim of this systematic review and meta-analysis was to assess and compare
peri-implant marginal bone loss in cement- and screw-retained prostheses.
Material and Methods: Electronic database and manual searches were undertaken
to identify trials, prospective or retrospective studies reporting on radiographic
marginal bone loss around dental implants restored with cement- and/or screwretained
prostheses. Two reviewers independently conducted the article selection
and data extraction. Random-effects models were used to obtain estimates of
peri-implant marginal bone loss [mean, 95% confidence intervals (CI)].
Results: Of the 1217 identified studies, nine finally met the inclusion criteria. Only
two studies included both cement- and screw-retained prostheses, three assessed
only screw-retained prostheses, and four evaluated only cement-retained prostheses.
Pooled mean marginal bone loss was 0.53 mm (CI 95%, 0.31–0.76 mm) for cementretained
prostheses and 0.89 mm (CI 95%, 0.45–1.33 mm) for screw-retained
prostheses.
Conclusion: There is no evidence to support differences in the marginal bone loss
through indirect comparison between cement and screw-retained restorations.

The majority of patients often have functional problems after undergoing jaw reconstruction. These patients require intense rehabilitation, including surgical and prosthodontic procedures to maximize function, esthetics, and to preserve mastication, speech, and appearance. This clinical report describes the rehabilitation of a patient who had a large tumor resection of ameloblastoma of the mandible resulting in hard and soft tissue deficiency. The mandible was reconstructed with an iliac bone graft with simultaneous tumor removal. Two implants were placed. The prosthodontic rehabilitation was completed with an implant-supported, screw-retained hybrid prosthesis fabricated on a CAD/CAM titanium framework. No technical or prosthetic complications were observed in a 2-year follow up period. The prosthesis improved the quality of life of the patient.

Osseointegration was discovered in 1962 and coined as a term in 1977. Original definitions implied direct contact between foreign materials and bone without any interposed soft tissue layers. Today, osseointegration is regarded to be a foreign body response to separate foreign elements from bone. A new definition of the term is suggested in this paper; " Osseointegration is a foreign body reaction where interfacial bone is formed as a defense reaction to shield off the implant from the tissues ". Excellent clinical results of osseointegrated implants have been reported from dentistry and Ear Nose Throat surgery, the latter with the indications of a stable anchorage of hearing aids or facial epistheses in cases of facial trauma. In Orthopaedic surgery a randomized controlled clinical trial has been undertaken demonstrating very good clinical results supported by positive radiostereo-photogrammetical data.

Students are inspired to take up dentistry for factors related to security, social and professional status, financial rewards, better quality of life, and for working with people. The period of internship is the most suitable period to plan the future strategy by setting up professional goals for an appropriate career path. The number of options after graduating dentistry is many and choosing the best option that will satisfy passion as well as income, having an overall professional goal will enable to secure a bright and secure future in dentistry. In many instances parents take up the decision to place their children in dentistry based on their knowledge and then it is the turn of the children to put in their best efforts to succeed in life as they are matured enough to judge the need of their souls. Earning money as well as serving the people who are in need must be the vision of every graduating student. Dentistry gives a secured platform to take up the field of specialized interest and even if it fails to succeed there are always diverse options. The articles located, extracted and reviewed were relevant studies published in English language from selected websites and dental journals published online. This review article makes an attempt to focus on the different career paths available for students to pursue after their Bachelor graduation in dentistry. Key message: The responsibility in life does not just end as an Intern but it is miles to go. Dentistry gives a secured platform to take up the field of specialized interest and even if it fails to succeed there are always other options after graduation.

Introducción: Los implantes en la zona estética son un desafío por la demanda de función y estética. Los implantes inmediatos son una alternativa para recuperar los dientes de forma rápida y efi caz, conservando los tejidos óseos y blandos. El objetivo de este estudio fue evaluar la tasa de supervivencia, los cambios óseos marginales, de los tejidos blandos y la satisfacción del paciente utilizando carga inmediata funcional en la zona estética sobre implantes postextrac-ción. Material y métodos: Los implantes se colocaron en sitios pos-textracción sin elevar ningún colgajo con carga inmediata funcional a las 24 horas. Un alvéolo con una brecha de aproximadamente 2 mm recibió un relleno óseo junto con una provisional funcional, sus-tituyéndola por una prótesis defi nitiva a los seis meses. Se evaluó la tasa de supervivencia, la estabilidad de los tejidos blandos, la pérdida ósea y la satisfacción de los pacientes. La pérdida ósea marginal fue evaluada mediante radiografías para comparar las medias y la desviación estándar (media ± DE) tanto en mesial y distal. Del mismo modo, en las papilas y la recesión gingival (media ± DE) se realiza un cuestionario de satisfacción. Resultados: Se logra una tasa de supervivencia de 100%. Durante el seguimiento hubo estabilidad de los tejidos blandos con ausencia de recesión (0.12 ± 0.15) y conser-vación de las papilas (0.017 ± 0.204). El nivel de la pérdida ósea del implante a los 12 meses es 0.38 ± 0.64 mm, una media en mesial de 0.33 ± 0.26 mm y en distal 0.42 ± 0.20. 100% estuvo satisfecho con los resultados. Conclusiones: Los resultados mostraron que la carga inmediata funcional de implantes colocados en alvéolos postextracción puede considerarse un procedimiento predecible por preservar los tejidos duros y blandos al año de seguimiento; mejorando la satisfacción y confort por el resultado. ABSTRACT Introduction: The implants in the esthetic zone are challenging demand function and aesthetics. Immediate implants are an alternative to recover teeth quickly and efficiently, keeping bone and soft tissue. The aim of this study was to evaluate the survival rate, marginal soft tissue and bone changes; and patient satisfaction, using functional immediate loading in the esthetic zone on postextraction implants. Material and methods: The implants were placed in post-extraction sites with fl apless surgery, functional immediately loaded at 24 hours. An alveolus a gap of about 2 mm with a bone fi ller received provisional functional and replaced by a defi nitive prosthesis six months. Survival rate, stability of soft tissue, bone loss was evaluated; and patient satisfaction. The marginal bone loss was assessed by radiographs to compare the mean and standard deviation (mean ± SD) both mesial and distal. Similarly in the soft tissues, the papillae and gingival recession (mean ± SD) and a satisfaction survey is performed. Results: A survival rate of 100% is achieved. During follow-up there was stability of soft tissue with no recession (0.12 ± 0.15) and conservation of the papillae (0.017 ± 0.204). The level of bone loss implant at 12 months is 0.38 ± 0.64 mm, an average of 0.33 ± mesial and distal 0.26 mm 0.42 ± 0.20. 100% were satisfi ed with the results. Conclusions: The results showed that the functional immediate loading of implants placed in postextraction sockets, could be considered a predictable procedure to preserve the hard and soft tissues year follow-up; improving satisfaction and comfort for the result.

RESUMEN Los tratamientos de implantes dentales se han convertido en un tratamiento cotidiano dentro de la práctica diaria, por lo que la presencia de defectos del reborde alveolar que se da por la reabsorción ósea ha conllevado al desarrollo de muchos procedimientos de aumento óseo con la intención de mejorar la cantidad y calidad del hueso, para así lograr un tratamiento de implantes dentales predecible. El objetivo de esta revisión de la literatura es la de presentar los principales procedimientos referidos al manejo de los defectos horizontales del reborde alveolar, que siempre representan un desafío para los clínicos. ABSTRACT Dental implant treatments have become a daily treatment within daily practice, so that the presence of defects of the alveolar ridge that results from bone resorption has led to the development of many bone augmentation procedures with the intention of improving the quantity and quality of the bone to achieve a predictable dental implant treatment. The objective of this review of the literature is to present the main procedures related to the management of horizontal defects of the alveolar ridge, which are always a challenge for clinicians.

Le développement d'un remplaçant idéal pour les dents absentes a été
le premier but à long terme de la dentisterie. Un implant dentaire est une vis biocompatible en titan est ancrer chirurgicalement dans la mâchoire. La modélisation numérique du comportement mécanique des implants dentaires et plus particulièrement de l'interface os-implant a été menée dans le but d'une part d’aider à l'optimisation géométrique de la forme des implants dentaires en vue d’analyser les contraintes mécaniques à l'interface osimplant, et d'apporter d'autre part des réponses aux questions sur la fiabilité des implants déjà dans le marché.
Dans cette étude nous avons choisi un implant dentaire d’une seconde
prémolaire de la mâchoire inferieur pour analyser l’effet du chargement
dynamique et la surcharge sur la distribution des contraintes dans les
différentes composantes implantaire. Pour cette raison, le système d’implant à été modéliser numériquement par la technique des éléments finis tridimensionnelle en utilisant le programme ABAQUS. Les résultats obtenus montrent que les contraintes étaient maximales dans l'os cortical au collet de l'implant et le plus faible dans l'os spongieux. Tout fois, les pics de surcharge génèrent une forte concentration de contrainte dans les différents composants du système.

Objectives: Bone grafts are often used to enhance bone volume/quality prior to implantation insertion. This systematic review compares the histomorphometric effectiveness of bone grafts in an evidence-based manner. Data: Randomized clinical trials comparing histomorphometrically the% of newly-formed bone between two grafts were included. Risk of bias within and across studies was assessed with the Cochrane tool and the GRADE approach, respectively. Random-effects pairwise meta-analyses were conducted, followed by network meta-analysis, network meta-regression and sensitivity analyses. Sources: Four electronic databases were searched from inception to June 2015 without limitations. Study selection: A total of 12 trials (5 parallel; 7 cluster) with a total of 231 patients (302 grafted sites) were included. No statistically significant differences were found in the% of new bone from pairwise comparisons between any two bone grafts. Treatment ranking based on the evidence network indicated that autografts presented the highest% of new bone, followed by synthetic grafts, xenografts, and allografts. No differences according to patient age, sex, healing time, membrane used or kind of surgical graft use were identified. Our confidence on pairwise comparisons was moderate to very low, due to study limitations, inconsistency, and imprecision; our confidence on graft ranking was moderate, due to study limitations. Conclusions: No significant differences were found in the% of new bone between any two grafts. Clinical significance: Synthetic bone substitutes or xenologous bone grafts can be used as an alternative to autologous graft, in order to overcome problems of additional surgeries or limited graft availability.

El tratamiento de colocación de implantes para la reposición de dientes ausentes es un procedimiento común y aceptable en periodontología, por su alto grado de biocompatibilidad y oseointegración, que lo hace una alternativa predecible, sin embargo la pérdida de implantes dentales a corto o largo plazo es una delas complicaciones posibles. La regeneración ósea guiada es una alternativa para restaurar el volumen de la cresta alveolar deficiente, que aumenta la dimensión horizontal y vertical de las crestas óseas, con el fin de permitir la oseointegración y estabilidad a largo plazo de futuros tratamientos de implantes. Se obtiene mediante el uso de membranas reabsorbibles y no reabsorbibles, con o sin el uso de materiales de injerto óseo.

In recent years, there have been major advances and increasing amounts of research on the utilization of natural polymeric materials as drug delivery vehicles due to their biocompatibility and biodegradability. Seaweed polysaccharides are abundant resources and have been extensively studied for several biological, biomedical, and functional food applications. The exploration of seaweed polysaccharides for drug delivery applications is still in its infancy. Alginate, carrageenan, fucoidan, ulvan, and laminarin are polysaccharides commonly isolated from seaweed. These natural polymers can be converted into nanoparticles (NPs) by different types of methods, such as ionic gelation, emulsion, and polyelectrolyte complexing. Ionic gelation and polyelectrolyte complexing are commonly employed by adding cationic molecules to these anionic polymers to produce NPs of a desired shape, size, and charge. In the present review, we have discussed the preparation of seaweed polysaccharide-based NPs using different types of methods as well as their usage as carriers for the delivery of various therapeutic molecules (e.g., proteins, peptides, anti-cancer drugs, and antibiotics). Seaweed polysaccharide-based NPs exhibit suitable particle size, high drug encapsulation, and sustained drug release with high biocompatibility, thereby demonstrating their high potential for safe and efficient drug delivery.

Most treatment methods for myofascial pain are empirical and aimed at the painful trigger points with the purpose of ablating muscle spasm and restoring normal muscle length. The current study conducted on 72 patients suffering from pain and decreased mouth opening as result of temporo mandibular joint dysfunction. Patients divided into four groups and low level laser, dry needling, injection of local anesthetic agent and pulsed electromagnetic field were tried for treatment of myofascial trigger point's pain. Results showed that pulsed electromagnetic field is the most effective treatment modality regarding pain relief. In conclusion; pulsed electromagnetic field should be used as adjunctive treatment with other treatment modalities for better inactivation of myofascial trigger points.
