Interdisciplinary Management of an Adult Patient with A Class III Malocclusion
(2014) Pektas, Zafer Ozgur; Kircelli, Beyza Hancioglu; 24370388
The coexistence of a skeletal class III deformity and partial edentulism poses a clinical challenge and requires a comprehensive evaluation followed by a multidisciplinary approach. This clinical report presents the integrated management of a class Ill malocclusion in a 50-year-old woman with partial edentulism. The patient received adjunctive orthodontic treatment with a rigid temporary anchorage device, a Le Fort I maxillary osteotomy, and prosthodontic rehabilitation with removable maxillary copings, an overdenture, and a mandibular partial removable dental prosthesis with precision attachments.
Modified Blair Approach for the Treatment of Mandibular Condyle Fractures
(2022) Ozer, Cem; Tamer, Yusuf; Bayram, Burak; Pektas, Zafer Ozgur; 35220347
Purpose: The management of fractures of the condyle of the mandible has been a topic of debate and still no consensus exists in the literature about the most appropriate approach. The objective of this study was to evaluate the efficacy and safety of the modified Blair approach for the open reduction and internal fixation of mandibular condyle fractures. Methods: A retrospective study was conducted on 18 patients with 20 mandibular condyle fractures from 2014 to 2020. All patients were treated surgically using the modified Blair approach. Postoperative occlusion status and mouth opening were assessed for treatment outcomes. Also, the rate of complications such as facial nerve paralysis, wound infection, hematoma, salivary fistula, Frey syndrome, and greater auricular nerve paraeesthesia evaluated. Results: Seventeen out of 18 patients (94.4%) achieved their original pretraumatic occlusion after the surgery. One patient (5.5%) had postoperative occlusal interference due to premature dental contact. The maximal postoperative interincisal distance was measured with a range between 33 and 41 mm (mean 37.6 mm). One patient (5.6%) had transient facial nerve palsy. Also, salivary fistula developed in 1 (5.6%) patient in the postoperative period. Conclusion: The results of this study revealed that the modified Blair approach provides satisfactory clinical outcomes with low complication rates and may offer an alternative, safe, and effective method for open reduction and internal fixation of mandibular condyle fracture.
What Is the Role of Endodontic Predisposing Factors in Early Implant Failure?
(2020) Sisli, Selen Nihal; Pektas, Zafer Ozgur; 32315422
We aimed to investigate a possible relationship between early implant failure (EIF) and an adjacent root canal-treated tooth and/or tooth with a periapical lesion (PL), considering the duration between implantation and root canal treatment (RCT). The importance of prior RCT and/or presence of a PL before implantation was also investigated. A total of 810 implants from 342 patients were included and scored according to the implant failure before abutment connection, adjacent root canal treated teeth, adjacent teeth without RCT, no adjacent teeth, adjacent teeth with PL, extraction of teeth with PL, and/or RCT before implantation. The durations between the extraction and implantation and between RCT and implantation adjacent to the root canal-treated teeth were recorded. The time from the RCT of adjacent teeth to implant placement was categorized into 5 groups: less than 4 weeks before implantation, 4-12 weeks before implantation, at least 12 weeks before implantation, within 4 weeks after implantation, and at least 4 weeks after implantation. Among the endodontic predictors, a prior PL on the tooth extracted was associated with an increased risk of EIF (P < .05, odds ratio: 437; 95% confidence interval: 1.604-11.891). Furthermore, EIF was more likely to occur when the RCT of an adjacent tooth was performed within 4 weeks of implantation (P < .05). Additional investigations with larger sample sizes are necessary to validate our findings.
