The depth, length, and depth:length ratio of the mandibular fossa, and the angles of the posterior slope of the articular eminence were measured for 91 temporomandibular joints (TMJ) with anterior disk displacement (ADD) in 79 female patients with TMJ dysfunction. As a control, 48 joints in 24 females without TMJ dysfunction were similarly measured. One of the angeles of the posterior slope of the articular eminence was larger for joints with ADD than for the controls (P < 0.01, Student's t-test). There were no other statistically significant differences between the two groups. Among the 91 joints with ADD, there was no statistically significant difference in any variable between joints with ADD with reduction (n = 46) and those with ADD without reduction (n = 45); likewise, there was no association between the magnitude of angle of the posterior slope of the articular eminence and overjet, overbite, canine relationship, or molar relationship.

Three-dimensional finite element feature analysis of the mandible and morphology and position of temporomandibular joint in patients with unilateral and bilateral molar scissor bite.

Objectives: The objective of this study is to measuring the morphology and position of bilateral temporomandibular joints in patients with unilateral and bilateral molar scissor bite and simulating the deformation of the mandible during occlusion, in order to provide thesis for the diagnosis of temporomandibular joint disease in patients with unilateral and bilateral molar scissor bite.
Methods: This study was a retrospective study. A total of 10 patients with unilateral molar scissor bite (the unilateral molar scissor bite group) and 10 patients with bilateral molar scissor bite (the bilateral molar scissor bite group) were selected as the experimental group, and 20 adult patients with classⅠ of angle classification of similar ages were selected as the control group.
Temporal changes of tibial eminence after bi-cruciate retaining total knee arthroplasty.

Background: Bicruciate-retaining (BCR) prostheses have been introduced to recreate normal knee movements by preserving both the anterior and posterior cruciate ligaments. One of the surgical procedures essential to the success of BCR total knee arthroplasty (TKA) is preservation of the tibial eminence. However, in our clinical experience, we found that a well-preserved tibial eminence changed its shape chronologically after the operation.

Introduction The role of the condylar position in the correct functioning of the stomatognathic system has been the center of the study. Using cone-beam computed tomography (CBCT), this study looked at the three-dimensional (3D) position of the condylar bone in patients from Class I, Class II, Division 1, and Division 2. Materials and methods This cross-sectional, retrospective study was conducted using 102 CBCT records, with 34 records allocated to each category of malocclusion classification, such as dentoskeletal Class I, skeletal Class II, and dental Class II, Division 1 and 2.

Article Synopsis
- - Chondroblastoma is a rare bone tumor found at the ends of bones, accounting for about 1% of primary bone tumors. It can be invasive, and there's a risk of recurrence after traditional open surgery, which can also cause damage to the bone structure.
- - In this case study, a 14-year-old male underwent a successful arthroscopic procedure to remove a chondroblastoma from the proximal tibia. The surgery involved careful lesion excision and bone cavity management, using a substitute for autologous bone grafts.
- - After one year of follow-up, the patient showed no symptoms or knee issues, and imaging confirmed successful bone graft healing without recurrence, suggesting that arthroscopic surgery could be a viable
