Abstract:
The purpose of this study was to observe mandibular condyle shape and position in an asymptomatic population. In o rder to carry out this study, 142 temporomandibular joints in 71 adults(35 males, 36 females), who were asymptomatic for temporomandibular joint disorders and had no history of prosthodontic or orthodontic treatments, were selected, and rad iographed using the Accurd-200 head holder(Denar Co., U.S.A.) for lateral individualized corrected tomograms. Mandibular condyles were classified morphologically and evaluated in positional relationships with articular fossae and articular eminences at centric occlusiohn and 1 inch mouth opening. The obtained results were as follows : 1. In the classification of mandibular condyle shape, the convex type was more prevalent in trascranial radiograms and tomograms taken at medial, central, and lateral locations. 2. In the mandibular condyle position at centric occlusion, the mandibular condyles were palced posterior to the center of articular fossae in trascranial radiograns and anterior to the center of articular fossae in tomograns taken at medi al, central, and lateral locations. 3. In the mandibular condyle position in right and left TMJs at centric occlusion, the mandibular condyles were placed bilateral asymmetric relationships to the articular fossae in trascranial radiograms and tomograms taken at medial, cent ral, and lateral location, 4. In the mandibular condyle position at 1 inch mouth opening, the mandibular condyles were placed anterior to the arti cular eminences in trascranial radiogramas and tomograms taken at central location and posterior to the articular eminen ces in tomograms taken at medial and lateral locations.
