A comparison between the arbitrary and kinematic intercondylar distances of full mouth rehabilitation patients (An in-vivo study)

Abstract

Background: The intercondylar distance can change the radius of movement and affect the arcs traveled by thecusps during lateral mandibular excursions in the horizontal plane. The aim of this study was to record and comparethe intercondylar distances of male and female patients requiring full mouth rehabilitation by using arbitrary andkinematic face-bows.Materials and methods: Interfacial widths of fifty asymptomatic male and female full mouth rehabilitation patientswere recovered from arbitrary and kinematic face-bows. Intercondylar distances were recorded and statisticallycompared.Results: Results indicated that arbitrary and kinematic intercondylar distances of male patients were significantlygreater than females indicating asymmetry in locating the condylar axes of rotation in both sexes.Conclusion: The majority of intercondylar distances of patients were more than 110 mm indicating that an articulatorwith an adjustable intercondylar distance would be more anatomically correct for the treatment of full mouthrehabilitation cases
