Hence, the following in vitro study was conducted to assess the accuracy of implant positioning and self-efficacy of novice compared to experienced surgeons for placing implant using freehand (FH), pilot drill-based partial guidance (PPG) and dynamic navigation (DN) approaches. The findings revealed that DN significantly improved the angular accuracy of implant placement compared with FH (P < 0.001) and PPG approaches (P < 0.001). The time required with DN was significantly longer than FH and PPG (P < 0.001), however, it was similar for both novice and experienced practitioners. The surgeon's self-confidence questionnaire suggested that novice practitioners scored higher with both guided approaches, whereas experienced practitioners achieved higher scoring with PPG and FH compared to DN. In conclusion, implant placement executed under the guidance of DN showed high accuracy irrespective of the practitioner's experience. The application of DN could be regarded as a beneficial tool for novices who offered high confidence of using the navigation system with the same level of accuracy and surgical time as that of experienced practitioners. Dental implant surgery is a widely accepted therapeutic option for partially and fully edentulous patients. An ideal three-dimensional (3D) implant positioning and angulation is a prerequisite to ensure its long-term stable esthetic and functional outcome and to facilitate a correct prosthetic phase 1. In contrast, non-ideal implant positioning may cause collateral damage to the vital anatomical structures within the vicinity of the placed implant and lead to certain intra-operative complications, such as maxillary sinus and/or cortical perforation, inferior alveolar nerve injury and damage to adjacent teeth 2. Furthermore, an imprecise positioning of the implant has also been known to cause peri-implant bone loss and peri-implantitis at follow-up 2. Hence, it is necessary that a surgeon should have a high level of experience and sufficient 3D spatial awareness to avoid complications associated with non-ideal placement of dental implants 3. The wide adoption of cone-beam computed tomography (CBCT) coupled with computer-aided design and computer-aided manufacturing (CAD/CAM) in a dental practice has improved the implant placement accuracy compared to freehand (FH) approach and allowed delivery of predictable prosthetically-driven treatment

Methods: A total of 72 implants were placed in 36 simulation models. Three experienced and three novice practitioners were recruited for performing the osteotomy and implant insertion with freehand, surgical guide (pilot-drill guidance) and navigation (X-Guide, X-Nav technologies) approaches. Each practitioner inserted 4 implants per approach randomly with a 1-week gap to avoid memory bias (4 insertion sites × 3 approaches × 6 practitioners = 72 implants). The performance of practitioners was assessed by comparing actual implant deviation to the planned position, time required for implant placement and questionnaire-based self-confidence evaluation of practitioners on a scale of 1-30. Results: The navigation approach significantly improved angular deviation compared with freehand (P < 0.001) and surgical guide (P < 0.001) irrespective of the experience. Surgical time with navigation was significantly longer compared to the freehand approach (P < 0.001), where experienced practitioners performed significantly faster compared to novice practitioners (P < 0.001). Overall, self-confidence was higher in favor of novice practitioners with both guided approaches. In addition, the confidence of novice practitioners (median score = 26) was comparable to that of experienced practitioners (median score = 27) for placing implants with the navigation approach. Conclusions: Dynamic navigation system could act as a viable tool for dental implant placement. Unlike freehand and static-guided approaches, novice practitioners showed comparable accuracy and self-confidence to that of experienced practitioners with the navigation approach.

Because of fast infection spreading, delay in diagnosis and treatment can result in permanent damage. PRESENTATION OF CASE: A 55-year old presented with a right-sided subperiosteal orbital abscess originating from a decayed first upper molar. The associated loss of vision improved only after a extraoral surgical drainage. Three years later, recurrent headaches, photobia and ptosis still persist. DISCUSSION: Our case demonstrates a rare but potentially hazardous complication of untreated dental infections. The effect of antibiotics is often overestimated, and lack of treatment may lead to serious sequelae, certainly when the orbital infection is located posterior to the orbital septum. When intraoral drainage is insufficient, the infection should be accessed extraorally. CONCLUSION: Orbital infections require a thorough clinical evaluation, including the oral cavity as dental infections may be overlooked. Dental radiograpy plays a major role. Prompt and adequate treatment is crucial in preventing further spreading of odontogenic infections.

The ‘International Society for the Study of Vascular Anomalies’ (ISSVA) is the most widely accepted classification in the literature and is mainly based on the radiologic and clinical presentation. The aim of this article is to review the clinical practice of diagnosis and treatment of vascular anomalies in the head and neck region in a university hospital, with special focus on the nomenclature. All patients with a vascular anomaly presenting to the department of oral and maxillofacial surgery were reviewed in a retrospective manner. Nomenclature, diagnostic process, lesion characteristics, treatment and outcome were examined. The lesions were (re)classified according to the ISSVA classification. A total of 185 patients were identified, of which 12.4% (n = 23) had a congenital anomaly. After reclassification, the most common lesions were venous malformations (...

Such a surgical procedure requires radiographic imaging pre- and postoperatively for diagnosis, treatment planning, and outcome assessment. Cone beam computed tomography (CBCT) has become a well-established imaging modality in the dentomaxillofacial region. The following narrative review is aimed to provide clinicians with an overview of the role of three-dimensional (3D) CBCT imaging for diagnostics, treatment planning, and postoperative monitoring of SFE procedures. CBCT imaging prior to SFE provides surgeons with a more detailed view of the surgical site, allows for the detection of potential pathologies three-dimensionally, and helps to virtually plan the procedure more precisely while reducing patient morbidity. In addition, it serves as a useful follow-up tool for assessing sinus and bone graft changes. Meanwhile, using CBCT imaging has to be s...

Very rare is the occurrence of those lesions in the skull, where they show a tendency for significant bone destruction and local recurrence. We present a case of a 36-year-old woman that presented with right pre-auricular swelling. Imaging revealed destruction of the glenoid fossa with penetration of temporal bone, skull base and central cranial fossa. Histopathological analysis revealed a giant cell tumor of the bone. An incomplete resection of this lesion has been performed due to the extensiveness and location of the tumor into the skull. In contrary to literature findings which advocate additional radiotherapy after subtotal resection to prevent recurrence, a 32-year follow-up using MRI showed no volume increase nor recurrence of the lesion compared to the initial scans.

Bone augmentation is usually required in the posterior maxilla to enable placement of a sufficient number and length of implants to support implant prosthesis due to the poor bone quality of the posterior maxilla. The recent invention of new surgical techniques and implant systems help circumvent the current restorative problems and provide a solution to erstwhile un-rehabilitated cases. The use of pterygoid implants in the pterygo-maxillary region provides posterior bone support without sinus augmentation or supplemental grafts. This article describes a clinical procedure for the restoration of severely resorbed maxilla using a new pterygoid implant in combination with conventional or cortically fixed implant system. In the present study, the use of implants in the posterior maxilla to support a fixed prosthesis was demonstrated to be a reliable and a good alternative to distal cantilever prostheses or sinus-...

This report describes the case of a 7-year-old boy who had pain in his right ear and limited mouth opening, following the onset of acute otitis media. A contrast-enhanced computed tomography scan revealed right-sided mastoiditis and hydrops of the right temporomandibular joint, suggesting septic arthritis. Real-time PCR and microbiologic analysis identified Streptococcus pyogenes and Staphylococcus epidermidis in the joint aspirate. Treatment with arthrocentesis and antibiotics led to full recovery of temporomandibular joint function.

Primary outcomes were functional and esthetic results using intra-and extra-oral images, clinical orthognathic measurements, radiological cephalograms, and cone beam computed tomography, including three-dimensional cephalometry analyzing the facial symmetry of hard tissues. The secondary outcome was patient quality of life using the Ferrans and Powers Generic Quality of Life Index. Ten patients were included; two had medical treatment, three had reconstructive surgery, four had orthognathic surgery, and three had lipofilling. Two patients had post-surgical infectious complications. Two patients developed neuropathic pain. Three-dimensional cephalometry showed no significant difference with regards to anatomical bony landmarks between the affected and non-affected sides. A volumetric analysis showed a significant difference (P¼0.04) in maxillary volumes. Seven patients were satisfied with their aesthetic and functional outcomes. Mean follow up was eleven years. In conclusion, this study should be interpreted carefully due to small sample size. We feel most patients can be treated conservatively or with minor aesthetic corrections using fat grafting methods. Use of allografts and osteosynthesis materials was associated with an increased risk of postoperative superinfection. Fat grafts produced predictable, noncomplicated results and can be used during disease progression. Threedimensional analysis showed acceptable symmetry of the bony framework on follow-up.

The aim of this study was to systematically review the management of sinus graft infection in order to define which protocols should be implemented. The terms searched in each database were ''sinus graft infection management'', ''maxillary sinus lift infection'', ''maxillary sinus graft infection'', ''maxillary sinus elevation infection'', and ''maxillary sinus augmentation infection''. The management of the sinus graft infection was assessed. The outcomes evaluated were maxillary sinus health and dental implantation results. The initial search yielded 1190 results. Eighteen articles were included, reporting a total of 3319 patients and 217 sinus graft infections. Drainage was performed with an intraoral approach in 13 studies, an endoscopic approach in two studies, and a combined approach in three studies. In every study, a disease-free sinus was finally obtained in all patients, but the outcomes of the graft and the dental implant were more varied. It is not possible to define the best treatment protocol for sinus graft infections based on the published data, since the level of evidence is poor. Management is very heterogeneous. This review highlights the necessity of surgical treatment associated with antibiotic therapy.
