Abstract Objectives The aim of this study was to assess the dimensional and volumetric changes in the mandibular condyle in Kennedy class I patients versus completely dentate patients by cone beam computed tomography (CBCT) to estimate the effect of loss of posterior teeth on the mandibular condyle. Patients and methods This study was performed on one hundred patients requesting CBCT scans: fifty Kennedy class I patients and fifty fully dentate controls. Condyle dimensions mesio-distal, cranio-caudal and antero-posterior as well as condyle volume were measured in both the groups. Results Kennedy class I patients showed statistically significant higher mean condyle width but lower mean condyle height than the control group. No statistically significant difference was found between the study group and the control group regarding condyle AP dimension. There was no statistically significant difference between condyle volumes in the two groups. Conclusion Loss of posterior teeth is accompanied by significant decrease in condyle height and increase in condyle width with no change in the total condyle volume or antero-posterior dimensions.

Introduction The condyle is a very special part of the TMJ. It expresses the center of mandibular growth [1]. In adulthood, it varies considerably both in size and shape [2]. In response to continuous stimuli, the condyle undergoes a remodeling process where its final dimensions and volume are linked to the relation between the maxillary and mandibular bases [3]. Even in adulthood, the mandibular condyle seems to answer to functional demands, as it is continuously subjected to a remodeling process, which could affect its volume and shape [4]. Teeth are the main functional component of the oral cavity. Teeth provide a variety of function including mastication, speech and esthetics [5]. Tooth loss occurs in the oral cavity by various causes such as dental caries, periodontal diseases, trauma, pulpal and periapical diseases and various * Naglaa F.

systemic diseases [6]. The teeth provide a stable vertical and horizontal relation of mandible to maxilla and provide guiding planes for movement of the mandible anteriorly and laterally in the range of the mandibular movement during which the teeth are in contact. Loss of posterior teeth followed by loss of occlusal curve may tip the balance from adaptation with functional harmony towards disordered function [7]. The
