Abstract
Background
Bilateral Sagittal Split Osteotomy (BSSO) is one of the treatment options for Class III maxillary deficiency which may affect the condylar position and the patient's occlusion. We aimed to evaluate the clinical and radiographic changes of temporomandibular joint (TMJ) following mandibular set back surgery by BSSO.
Methods
In this retrospective study, All Class III patients, aged between 18-30 years old who underwent bimaxillary orthognathic surgery in the Oral and Maxillofacial Surgery Ward of Ghaem Hospital, Mashhad, Iran from January 2018- January 2020 were enrolled. Radiographic changes of joint space, condylar position and clinical changes for maximal mouth opening and joint sound were examined before and 6 months after surgery. Data were analyzed by SPSS16 software and the significance level of the data was set at P-value < 0.05.
Results
Twenty-five patients were recruited. The axial angle of the left and right condyle and condylar inclination on both sides reduced but this reduction was not statistically significant. While the anterior joint space was reduced and posterior joint space was increased in both sides, the changes on the right side were only significant (P = 0.039). In clinical examinations maximum mouth opening, lateral and protrusive movements were also decreased but this reduction was not statistically significant.
Conclusion
The mandibular set back with BSSO surgery in class III skeletal patients had no significant effect on the position of the condyle in the glenoid fossa as well as clinical symptoms.

Abstract
Many people were affected by COVID-19 in its severe form. Some intercurrences are still emerging. We here report two cases of COVID-related osteonecrosis of the jaws (CRONJ). Two retrospective cases were admitted into Imam Reza Hospital, Mashhad, Iran with suspected CRONJ. One patient escaped from hospital while the other showed a positive result after our proposed treatment. A new aftermath to COVID-19 infections is emerging. Maxillofacial and orthopedic surgeons should be aware of this situation. CRONJ should be on the suspect list in patients with COVID-19. Measures that are useful in the treatment carried out, as well as some measures recommended in the literature, were discussed. Surgical treatment of CRONJ appears to be an effective alternative, especially in the more aggressive cases.

Abstract
Background: Educational posters play a crucial role in education, information dissemination, and awareness. Their visual appeal efficiently communicates condensed yet vital information on significant topics, making them valuable for teaching sequential concepts. We aimed to assess the effectiveness of educational posters in the oral and maxillofacial surgery department for student education.
Methods: The study was carried out during the fall semester of 2022 at Mashhad Dental School, Mashhad, Iran utilizing a questionnaire-based approach. The questionnaire gathered demographic information and assessed students' perspectives on educational posters. Statistical analysis was performed using SPSS version 23 with a significance level set at 0.05.
Results: This study was conducted on 70 students (35 females and 35 males). Gender-based analysis demonstrated significant differences in beauty, adaptability, and learning, with male students scoring lower than females (P values = 0.036 and 0.031, respectively). Further analysis by academic year unveiled higher beauty and adaptability scores among third-year students compared to second-year students, showing statistical significance (P value = 0.035). A two-by-two comparison highlighted that the average beauty score of third and fifth-year students surpassed that of second-year students (P values = 0.041 and 0.038, respectively). In summary, higher academic years correlated with superior performance, emphasizing the potential impact of educational posters on academic outcomes.
Conclusion: Posters in the oral and maxillofacial surgery department received commendable ratings in various areas, positively impacting the teaching and learning process.

Abstract
Background: We aimed to determine whether collagen membrane coverage in maxillary sinus floor elevation surgery, provides an advantage regarding bone regeneration.
Methods: This randomized clinical trial included all healthy adults presented for dental implant placement in the posterior edentulous maxilla at the Maxillofacial Surgery Department of Mashhad Dental School, Mashhad, Iran from 2021-2022. Participants were candidates for sinus floor elevation surgery. Patients were randomly allocated to control (with membrane) and test (without membrane) groups. Surgery was performed through the lateral window technique and using allograft particles. According to the assigned study group; either a collagen membrane was placed over the osteotomy window or it was left uncovered. Six months after surgery when patients were recalled for implant placement, a bone specimen was obtained and sent for histologic and histomorphometric analysis. The predictor variable was the use of collagenous membrane and the outcome variables were the amount of newly formed bone, native bone, and connective tissue.
Results: A total of 30 consecutive patients, with a mean age of 46.33±7.25 years completed the study. Histomorphometric measurements, six months after augmentation revealed that the mean area of connective tissue was significantly less in the group with membrane coverage (P=0.015). The area of newly formed bone was significantly greater in sites covered with a collagen membrane compared to grafted but uncovered sites; (P <0.001).
Conclusion: Covering the lateral osteotomy window with a bioabsorbable collagenous membrane is able to significantly enhance vital bone formation and decrease connective tissue proliferation.
