Abstract Introduction: Temporomandibular joint disorders (TMD) are the most common disorders of the jaw, and despite their clinical importance, they are not completely understood. This study was aimed to evaluate the changes of temporomandibular joint (TMJ) on cone beam computed tomography (CBCT) images in disc displacement vs. osteoarthritis of the TMJ. Methods: In this study, 45 patients, inc...

BACKGROUND This study was performed to evaluate three-dimensional positional change of the condyle using three-dimensional computed tomography (3D-CT) following unilateral sagittal split ramus osteotomy (USSRO) in patients with mandibular prognathism. METHODS This study examined two patients exhibiting skeletal class III malocclusion with facial asymmetry who underwent USSRO for a mandibular ...

INTRODUCTION The seated condylar position (SCP), also known as centric relation (CR), is considered the most reliable and reproducible reference point for accurately recording the relationship of the mandible to the maxilla. Therefore, a determination of the SCP/CR is a prerequisite for the analyses of the dental interarch, condylar position, and skeletal relationships. The purpose of this pros...

OBJECTIVE To compare condylar position and morphology among different vertical skeletal patterns. METHODS Diagnostic cone-beam computed tomography images of 60 adult patients (120 temporomandibular joints) who visited the orthodontic clinic of Hallym University Sacred Heart Hospital were reviewed. The subjects were divided into three equal groups according to the mandibular plane angle: hypod...

BACKGROUND AND OBJECTIVES The Influence of the loss of teeth on the condylar position and on temporomandibular joint (TMJ) dysfunction syndrome remains a c ontroversial issue. This study analyses the condylar position by means of a tomogram in partially dentate subjects which serves as a guide to predict which of the partially dentate statuses is prone to develop TMJ dysfunction syndrome in per...

It is very important to clarify the relationship between a dentofacial structure and a temporomandibular joint (TMJ) structure in orthognathic surgery. Recently, it was reported that the skeletal and occlusal patterns were associated with the TMJ morphology, including the disk position. In orthognathic surgery, some surgeons state that alterations in the condylar position from surgery can lead ...

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...

Results: Comparison between panorama and MRI revealed that there was statistically significant difference regard condyles position in panorama and condylar osseous changes in MRI, temporal cortical bone integrity in panorama and osseous condylar changes in MRIs and finally joints space narrowing in panorama and disc position, disc morphology, and joint effusion in MRIs. While, there was no stat...

The purpose of this paper is to present the technique for registration Seated Condylar Position (SCP)/Centric Relation (CR) position condyles: a two-piece wax bite with deprogramming and no mandibular manipulation.
