The purposes of this study were (i) to compare the reproducibility of lateral tooth contacts of casts mounted in a semi-adjustable articulator when condylar guidance was set by different methods and (ii) to assess the margin of error of the variations of condylar guidance without changing lateral tooth contacts, depending on the type of lateral guidance. In subjects with different types of late...

Unilateral condylar hyperplasia is an uncommon condition with unknown etiology which causes overdevelopment of condyle leading to facial asymmetry, mandibular deviation, malocclusion, and articulation dysfunction. Two Indian families with unilateral condylar hyperplasia are presented where the similar abnormality was also detected in one of their parents. The condylar hyperplasia in these two f...

The objective of this study is to explain mathematically the effect of curvature of horizontal balancing condylar path on that of tooth path. Conclusions from the calculation are; 1. Curvature of tooth path increases similar to that of horizontal balancing condylar path. 2. The relation of curvature between horizontal balancing condylar path and tooth path is hardly affected, even if the direct...

Adaptive remodelling of the condylar cartilage in response to mandibular protrusion constitutes the rationale for bite-jumping appliances to solicit growth modification. By investigating the expression of type X collagen and capillary endothelium, this study was designed to evaluate the osteogenic transition of chondrogenesis during adaptive remodelling of condylar cartilage and compare it with...

Recent emerging data indicate that the increase in the expression and activity of the transforming growth factor beta 1 (Tgf-β1) signaling may have detrimental effect to mature articular cartilage of knee joints. However, there is no information about whether or not this is the case in condylar cartilages. The objective of this study is to investigate the protein expression and activity of Tgf-...

AIM The aim of this international prospective randomized multi-centre study was to compare operative and conservative treatment of displaced condylar fractures of the mandible. METHODS AND PATIENTS Out of a total of 88 randomized patients from 7 centres, 66 patients with 79 fractures of the mandibular condylar process completed the study and were evaluated. All fractures were displaced, being...

To make artificial knee joints have lower long-term wear rate, a new method for reformed design of sagittal femoral condylar geometry based on TRIZ (Theory of Inventive Problem Solving) was proposed. Firstly, according to the development history of sagittal femoral condylar geometry and evolution theory of TRIZ, future state of the evolution line of femoral condylar geometry in sagittal plane w...

PURPOSE This study was performed to evaluate condylar surface changes and remodeling after orthognathic surgery using three-dimensional computed tomography (3D CT) imaging, including comparisons between the right and left sides and between the sexes. MATERIALS AND METHODS Forty patients (20 males and 20 females) who underwent multi-detector CT examinations before and after surgery were select...

t-condylar fracture of the distal humerus is rare in the skeletally immature children and is very rare in young children, under 9 years of age. this fracture has been classified  as:  type a ( minimally displaced or undisplaced), type b (displaced  but  not comminuted ) and type c (displaced and comminuted). herein, we report a t-condylar fracture of the distal humerus in a 5-yr-old boy. this f...

PURPOSE The aim of the present study was to investigate the relation between magnetic resonance (MR) evidence of joint effusion and concentrations of proinflammatory cytokines, including interleukin (IL)-1β and IL-6, in washed-out synovial fluid samples obtained from patients with mandibular condyle fractures. PATIENTS AND METHODS Twenty-five joints in 23 patients with mandibular condyle frac...
