Abstract
BACKGROUND: Condylar path is a path travelled by the mandibular condyle in the temporomandibular joint during various mandibular movements. The condyle will descend along the slope of articular eminence when it will move from centric relation to perform excursive movements. The angle at which the condyle moves from a horizontal reference plane is called Horizontal condylar angle. This condylar path inclination must be determined in relation to a horizontal plane of reference. AIM: To evaluate the Horizontal Condylar angle value using Computerised Digital Cephalometric Tracing. OBJECTIVES: 1) To assess the Horizontal Condylar angle established by FENN, SHILLINGBURG and FRANKFORT horizontal plane using Computerised Digital Cephalometric tracing. 2) To compare these values obtained, with that of clinically established Horizontal Condylar angle METHODS: This clinical study was performed on 30 dentate individuals and horizontal condylar angle was measured clinically from these subjects by using Semi- Adjustable Arcon type articulator and these values were compared with the three values obtained by lateral cephalogram to find out which value comes closest to clinically established horizontal condylar angle value. RESULTS: When both anterior and reference posterior reference points were used to trace the condylar path, it was observed that there was significant difference between the radiographic horizontal condylar angle values and clinically established horizontal condylar angle value. When only posterior reference point was used to trace condylar path, there was no significant difference between the radiographic value of Ala-tragus line (camper’s plane) and clinically established horizontal condylar angle value. INTERPRETATION AND CONCLUSION: Within the limitations of this study, it was concluded that the radiographic method can be used successfully as an adjunct to clinical methods of obtaining horizontal condylar inclination using Ala-tragus line (camper’s plane).
