“…In this innovative osteotomy (GBMO), the temporalis muscle, which inserts into the mandibular coronoid process, is inserted into the osteotomized anterior segment where the mandibular dental arch is located. The anterior and mid fibers are responsible for elevating the mandible, while the posterior fibers retract it [17].…”

Elective mandibular surgical osteotomies are commonly used to correct craniofacial discrepancies. Since the modifications proposed by Obwegeser, Dal Pont, and Hunsuck, no effective variations have been proposed to improve the biomechanical results of these mandibular osteotomies. With technological developments and the use of three-dimensional images from CT scans of patients, much has been done to plan and predict outcomes with greater precision and control. To date, 3D imaging and additive manufacturing technologies have not been used to their full potential to create innovative mandibular osteotomies. The use of 3D digital images obtained from CT scans as DICOM files, which were then converted to STL files, proved to be an efficient method of developing an innovative mandibular ramus beveled osteotomy technique. The new mandibular osteotomy is designed to reduce the likelihood of vasculo-nervous damage to the mandible, reduce the time and ease of surgery, and reduce post-operative complications. The proposed osteotomy does not affect traditional osteotomies. Anatomical structures such as the inferior alveolar nerve and intraoral surgical access were preserved and maintained, respectively. The results obtained from the digital images were validated on an additively manufactured 3D synthetic bone model.

“…As a result, the action of the temporalis muscle lifting the mandible posteriorly helps to bring the segmented bony boundaries closer together, which is exactly the opposite of what happens with conventional bilateral sagittal cut techniques [15][16][17].…”

Subject. The study of the results of the examination of the patients with the temporomandibular joint dysfunction depending on the habitual physical activity type. The aim of the study is to estimate the results of the examination of the patients with the temporomandibular joint dysfunction depending on the habitual physical activity type. Methodology. 105 patients (18 male patients and 87 female patients) aged 20-35 with the occlusive temporomandibular joint dysfunction (K07.6 Diseases of temporomandibular joint) living in Tyumen and in Tyumen region were examined. The study was carried out at “the Regional stomatological polyclinic” in Tyumen. Results. The study of the peculiarities of temporomandibular joint dysfunction depending on the habitual physical activity type was carried out. The clinical results of the dynamic observation and complex functional study in 105 patients aged 20-35 having occlusive temporomandibular joint dysfunction were given. Conclusion. The results showed that there was a direct connection between the changes in dentomandibular system and the physical activity level in 105 patients aged 20-35 with occlusive temporomandibular joint dysfunction living in Tyumen and Tyumen region. In the studied subjects, with a a low level of habitual motor activi 8.43% more defects in the dentition were found in comparison with a high level of habitual motor activity, and by 6.02% more than in comparison with an average level of habitual motor activity, the pathological abrasion of the teeth was almost 2 times higher compared with a high level of habitual motor activity. An additional examination method based on computed tomography showed a violation of the articular relationship in 67.3% of cases, signs of TMJ hypermobility one and two-sided in 28.2%, changes in the position of the condyles in the joint in 33.33% of cases, in the group with a low level of habitual motor activity.
