Abstract

Temporo-mandibular joint (TMJ) joint and the condyle of mandible are observed in the radiographs of the skull and the jaw. Therefore, it is of interest to assess the predictability of four different shapes of condyle in skeletal class I, II and III malocclusion. The four commonly visualized shapes are oval, bird beak, diamond and crooked were assessed using an ortho pantomogram (OPG). Each of the malocclusion was visualized for different shapes of the condyle. 987 OPGs were radiographically evaluated and the morphology of 1974 condylar heads was visualized. The shapes of the condyles were grouped under four different types. Data shows that oval shaped condyle was most common followed by bird beak. There was variability in the diamond and crooked shape and was lesser than the other types. Thus, the shapes of the condyle are useful predictable guide in deciding the nature of the occlusion.

Highlights

IntroductionThe anatomic features of Temporo-mandibular joint (TMJ) show variations among individuals in orthodontic treatment planning were broadly divided into and there are numerous factors that play a role in its shape and essential or non-essential diagnostic aids [9]

Summary

Introduction

The anatomic features of TMJ show variations among individuals in orthodontic treatment planning were broadly divided into and there are numerous factors that play a role in its shape and essential or non-essential diagnostic aids [9]. Management of are concerned with the differences in functional loads imposed TMD involves the work of dentists from various specialties There is a strong association between the form and multifactorial in nature and requires proper examination and function of the mandible and condyle among patients with treatment planning. It is of interest to evaluate the morphology of the condyle in Angles Class I, Class II and Class III malocclusions using ortho pantomograms and to assess if the type of malocclusions is a confounding factor in the shape of the condyle
