STATEMENT OF THE PROBLEM In orthognathic surgeries, proper condylar position is one of the most important factors in postoperative stability. Knowing the condylar movement after orthognathic surgery can help preventing postoperative instabilities. PURPOSE The aim of this study was to evaluate the condylar positional changes after Le Fort I maxillary superior repositioning along with mandibula...

OBJECTIVE Little is known about the natural progression of the disease process of temporomandibular joint (TMJ) osteoarthritis (OA), which affects approximately 1% of the US population. The goal of this study was to examine the early microarchitectural and molecular changes in the condylar cartilage and subchondral bone in biglycan/fibromodulin (Bgn/Fmod) double-deficient mice, which develop TM...

One of the many growth anomalies that affect the mandibular condyle is hemimandibular elongation without any condylar hyperplasia. Condylar growth patterns can be evaluated by serial clinical comparisons, cephalometric tracings and bone scanning with technetium 99m phosphate. However, no ideal method has been found to assess whether condylar overgrowth is “inactive”. Therapy is guided by the pa...

BACKGROUND A defect of condylar morphology can be caused by several sources. CASE REPORT A case of altered condylar morphology in adult male with temporomandibular disorders was reported in 30-year-old male patient. Erosion and flattening of the left mandibular condyle were observed by panoramic x-ray. The patient was treated with splint therapy that determined mandibular advancement. Eight m...

We describe our experience with conservative condylectomy for the correction of facial asymmetry in five patients with osteochondroma of the mandibular condyle. All five patients presented with malocclusion and facial asymmetry, which are common clinical findings of osteochondroma involving the mandibular condyle. We performed conservative condylectomy without additional orthognathic surgery fo...

BACKGROUND Most of healed lower femoral fractures resulted in various degree of loss of the knee motion. Flexion deficit is a serious problem for the Eastern persons that are where squatting and sitting on the ground are necessary for daily activities. The aims of this study were to compare outcomes of using condylar buttress plate and dynamic condylar screw (DCS) in treatment of distal femoral...

The purpose of this study was to measure the changes in facial, occlusal, and skeletal relationships in patients with active unilateral condylar hyperplasia whose sole treatment was a low condylectomy. A retrospective observational descriptive study was conducted. All patients had undergone a low condylectomy as the sole or initial surgical treatment. The size of the condylar segment removed wa...

The purpose of this study was to examine the changes in temporomandibular joint (TMJ) morphology and clinical symptoms after intraoral vertical ramus osteotomy (IVRO) with and without a Le Fort I osteotomy. Of 50 Japanese patients with mandibular prognathism with mandibular and bimaxillary asymmetry, 25 underwent IVRO and 25 underwent IVRO in combination with a Le Fort I osteotomy. The TMJ symp...

INTRODUCTION The mandibular condylar surface is made up of four layers, i.e., an external layer composed of dense connective tissue, followed by a layer of undifferentiated cells, hyaline cartilage and bone. Few studies have demonstrated the behavior of the condylar cartilage when the mandible is positioned posteriorly, as in treatments for correcting functional Class III malocclusion. OBJECT...

The chondrocytes of the articular condylar cartilage proliferate, hypertrophy and ultimately undergo apoptosis (programmed cell death), being replaced by osteoblasts. Converging results consolidate activator protein-1 (AP-1) transcription factor as the pivotal downstream effector in the early response of stress-sensitive cells to mechanical loading, and the Fra-1, Fra-2, JunB and JunD members o...
