Background: Cone beam computerized computed tomography (CBCT) has been widely indicated in dental implant procedure. The first step that the doctors should perform in local hospitals is to use orthopantomography for surgical planning to avoid and limit the risk of complications. As a result, determining the magnification amount of orthopantomography to achieve a precise diagnosis is clinically important. This study investigated the difference in measurement of the mental foramen (MF) position before dental surgery using 2 views of CBCT. Materials and Methods: Cone beam computed tomography scan was performed for 100 patients who required implant placement. In the panoramic and three-dimensional views of CBCT, the vertical distance between the margin of the mandible and the lower border of MF, and the horizontal distance between the mandibular symphysis and the mesial anterior border of MF were calculated. The differences between the 2 views were compared using Wilcoxonrank U test with P value 0.05 considered statistically significant. Results: The findings of this study showed a substantial statistical difference in the horizontal distance for the dentate patients in panoramic and three-dimensional views (22.7 AE 3.04 versus 21.1 AE 1.6), (22.5 AE 2.4 versus 20.9 AE 1.5) and left side (22.4 AE 2.8 versus 21.2 AE 1.6), (22.4 AE 2.8 versus 20.6 AE 1.4) of both genders. Concerning the vertical distance, a significant difference was also observed in the dentate (12.1 AE 2.1 versus 11.1 AE 1.4), (10.6 AE 1.4 versus 9.6 AE 1.3) and left side of the jaw (11.6 AE 1.95 versus 10.9 AE 1.2), (10.5 AE 1.2 versus 9.96 AE 1.4) for both genders in both views. In the edentulous and right side of the jaw, however no statistical difference was observed between male and female patients in terms of horizontal and vertical measurements.

Background: Lateral sinus augmentation and simultaneous insertion of dental implants is a highly predictable procedure and associated with high rate of implants success. Aims:To evaluate implant stability changes following maxillary sinus augmentation utilizing deproteinized bovine bone alone or mixed with platelet-rich fibrin.Materials and Methods: A total of 34 lateral sinus augmentation procedures were performed and 50 dental implants simultaneously installed. The lateral sinus augmentation cases were allocated randomly into 3 groups: Group A comprised 13 procedures and 21 dental implants utilizing solely deproteinized bovine bone. Group B involved 10 cases and 16 dental implants using deproteinized bovine bone mixed with leukocyte and platelet-rich fibrin. Group C included 11 operations and 13 dental implants employing deproteinized bovine bone mixed with advanced platelet-rich fibrin. Resonance frequency analysis test was performed immediately after implant installation and 24 weeks postoperatively for the measurement of the implant stability.Results: Implant stability quotient values increased significantly for all study groups 24 weeks after dental implants installation (P= 0.001). The implant stability quotient at T1 (day of implant installation) was 56.93 ±12.01 for group A, 58.34 ±12.82 for group B, and 61.35 ±8.47 for group C. The implant stability quotient at T2 (24 weeks after implant insertion) was 69.17 ±5.10, 69.43 ±5.32, and 68.50 ±7.44, respectively. Conclusion:The addition of leukocyte and platelet-rich fibrin or advanced platelet-rich fibrin to the bovine bone for sinus floor augmentation did not increased the implant stability quotient value in comparison to the bovine bone alone.

Intraoral mini-invasive technique is a surgical approach developed from the COMIT and the Aksoyler technique, which aims to overcome the limitations and complications of ORIF for the treatment of extracapsular condylar fractures. It consists of an intraoral incision giving access to the medial and lateral surfaces of the mandible, whose periosteum is elevated with a long and curved dissector to reach the fracture line. A stable distraction of the bone fragments is guaranteed by molar splints and RIF, while precise fracture reduction is performed with the periosteal dissector.In the literature, the treatment of choice for sub condylar fractures is an ongoing debate. The main concerns are related to the procedure complexity and the major complications such as the skin scarring caused by cutaneous accesses and facial asymmetry by FNI. 3,[7][8][9] Currently, these complications may have considerable social and economic consequences, especially among the young population. Microsurgical approaches to repair the nerve have been described, but the results are not guaranteed and often suboptimal. 10 The goals for an ideal treatment are optimal fracture reduction, functional preservation of the temporomandibular joints with class I occlusion, posterior ramous height restoration, and avoidance of facial scars or FNI.Aksoyler et al 2 and the author both accomplished these goals. Aksoyler worked with only the pediatric population, taking advantage of the tissue's remodeling capacity as explained by the Wolff's and Hueter-Volkman laws of bone remodeling, according to which the ramous height and angulation are restored.Aksoyler performed the fracture rim distraction using assistant digital pressure at the molar area in an unstable position.However, in this case, the patient was an adult, and the fracture distraction was obtained using molar splints and RIF. In this way, a precise reduction of the condylar fragment in a more stable mandible position was achieved. Excessive pressure of the periosteal dissector on the condylar fragment was avoided without any new dislocations or vascular complications.A favorable horizontal stump surface at the fracture rim is essential for the primary stability achieved by compression after the removal of the resin splint and the new positioning of the RIF. An oblique fracture rim needs the occlusal splint to be left in place in association with the RIF.The fracture stability control with radiological imaging such as X-rays and 3D-CT scans, both intraoperatively and postoperatively, is paramount.
