This prospective study includes 54 consecutive partially edentulous patients treated between December 2010 and October 2011. Outcome measures were: implant and prosthetic failures; biological and mechanical complications; marginal bone loss (MBL); sulcus bleeding index (SBI); and plaque score (PS). A total of 118 (29 narrow platform, 70 regular platform and 19 wide platform) NobelReplace Conical Connection implants were placed in both post-extraction sockets and healed sites and immediately loaded. The mean insertion torque was 63.4 ± 7.1 Ncm. One hundred out of 118 implants (84.7%) were inserted with a torque ranging between 55 and 70 Ncm. Each patient received a single prosthesis. At the 3-year follow-up, no patient dropped out and only two post-extractive implants failed (1.7%) in two patients (3.7%). The only complication (1.9%) observed was an event of perii...

However, no reports to date have undertaken detailed analyses of jaw bone quality using bone biopsy despite the large impact that jaw bone quality at the implant placement sites has on the prognosis of implant therapy. This study histologically examined jaw bone quality at implant placement sites using nondecalcified frozen sections. We also compared bone quality with attenuation (measured in Hounsfield units (HU)) on computed tomography (CT). Bone quality was highest around the anterior mandibular (67.25%), followed by the anterior maxillary (60.23%), mandibular molars (55.14%) and maxillary molars (44.81%). No statistical correlation with CT attenuation was evident (mean, 540.91 HU). These results suggested that consideration needs to be given to histological diagnosis as well as CT attenuation in clinical evaluations of bone where implant bodies should be placed.

Retrospectively, 200 consecutive NobelReplace Tapered Groovy implants of varying lengths and diameters were evaluated via implant stability quotient readings at placement (T1) and follow-up (T2). Data were analyzed by analysis of variance and simple linear regression tests. Intraoral location was statistically significant at T1 and T2. Although implant diameter was not statistically significant, implant length resulted in T1 (P = .08) and T2 (P = .09), which may have a clinically relevant effect on implant stability. An overall implant survival rate of 98% was achieved. Gender and age did not seem to affect implant stability quotient values at placement, follow-up, or implant survival. Intraoral location is an important factor in implant stability, with implants placed in the mandible being more stable than implants placed in the maxilla both at T1 and T2. Length may have...

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. 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.

We will hereby report on four cases of fracture of the mandibular condyle for which good outcomes were achieved by means of fixation and aggressive mouth-opening exercises using a bite plate as a type of conservative treatment. Patients between the ages of 6 and 53 years with the mean age of 37.25 years were investigated. The male to female ratio was 3:1. Of the four patients with fracture of the mandibular condyle, three exhibited midline fracture of the mandible. Bite plates were fabricated and intermaxillary fixation was conducted for 1-3 weeks with these bite plates for patients who presented at hospital from 1-10 days after injury and were refused surgery. After completion of intermaxillary fixation, aggressive mouth-opening exercises were implemented. Once sufficient mouth opening was possible, the healing progress was confirmed on computed tomography (CT) images. Treatment methods for fracture of the mandibular condyle include invasive and non-invasive ones. Favorable treatment outcomes were achieved with intermaxillary fixation using a bite plate and mouth-opening exercises in this study. Therefore, we conducted a preliminary study on the efficacy of this treatment and will hereby report on the results.

Many do not account for time to event or the lack of independence between implant-and patientlevel data. Many of these published survival rates are subject to observer bias, indicate the best possible outcomes, are overly simplistic, and are not generalizable to private practice. The profound difference between efficacy and effectiveness is often overlooked in the understanding of published survival rates. The single-center expert, academic center, or controlled trial (efficacy) presents an overly optimistic impression of what patients and clinicians should expect for survival rates of implants in the course of "normal" private practice. The goal of this study was to define a highly generalizable survival rate for implants placed in private practices across the United States using time-to-event analyses based on patient-level factors (effectiveness). For practicing clinicians and their patients, "survival" is a generally inadequate metric. What they must hope to have is a better understanding of "success, " yet the study undertaken here examined the former. As a multicenter, retrospective study, it is not possible to obtain standardized patient records over time (ie, radiographs, photographs, shade measurements, periodontal probings, soft tissue recession, plaque indices, prosthetic complications). Additionally, multiple conflicting definitions have been put forward regarding what constitutes a "successful" implant treatment. 7-10 Perhaps there can be no unified definition, and there should be a renewed focus on defining and accepting "survival" rates for clinicians in private practice. There is extensive variation in what individual patients and clinicians are willing to accept as a "success, " and the challenge increases with the attempt to include time and patient age as relevant factors.

MATERIALS AND METHODS One hundred implants were inserted into a uniform polyurethane block. The implants were distributed into 10 groups, with 10 implants each. The transducers were manually attached by a female operator (G female) and by a male operator (G male) using the standard connector provided by the manufacturers. For the remaining groups, the transducers were placed using a connector adapted to a digital torque wrench with different torque settings: 3 Ncm (G 3Ncm), 4 Ncm (G 4Ncm), 5 Ncm (G 5Ncm), 6 Ncm (G 6Ncm), 10 Ncm (G 10Ncm), 13 Ncm (G 13Ncm), 17 Ncm (G 17Ncm), and 20 Ncm (G 20Ncm). The stability was measured for all groups using both the Osstell and the Penguin resonance frequency analyzers. The minim...

The stent, with imbedded metal bearings, is worn by the patient during tomographic radiographic survey. The tomogram provides a more accurate image of the quantity and quality of the osseous structures. The same template may be used as a surgical stent to aid the surgeon in initial bur placement. Through careful planning and systematic control, the predictable placement of osseointegrated implants can be achieved. With cooperative efforts of restorative dentists and surgeons, more than 400 implants have been successfully placed at University of California, Los Angeles, School of Dentistry.

The objective of this study was to perform a retrospective study to verify the outcomes of horizontal bone reconstruction in implant dentistry with different types of materials and amounts of native bone in the recipient bed to allow for a new guideline for horizontal bone reconstruction. One hundred preoperative CT scans were retrospectively evaluated and categorized in accordance to horizontal bone defects as presence (Group P) or absence (Group A) of cancellous bone in the recipient bed. Different approaches were used to treat the edentulous ridge and the outcomes were defined either as satisfactory or unsatisfactory regarding the possibility of implant placement. The percentage distribution of the patients according to the presence or absence of cancellous bone was 92% for Group P and 8% for Group A. In Group P, 98% of the patients had satisfactory outcomes, and the use of a...
