A Study to Evaluate the Effect of Variation in an Arc of Radius, Anterior and Posterior Survey Point on Occlusal Plane Analysis
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2018, Vol 3, Issue 6
Abstract
An increased patients’ desire for aesthetic restoration, as seen in recent times, requires the restorative dentist to use a holistic approach in the management of teeth and its supporting structures; in order to achieve optimal function, aesthetics and comfort. One of the crucial factors in prosthetic rehabilitation of the dentition is the establishment of the patients’ functional and aesthetic occlusal plane. When multiple long span posterior restorations are planned, proper management of the occlusal plane in order to achieve posterior disclusion, become a necessary consideration. Very often, patients with mutilated dentition requiring rehabilitation, report to restorative dentist with severe worn out canine and other posterior teeth. Hence, it is mandatory to re-establish appropriate height of canine based on various factors like aesthetics, phonation and other biomechanical needs. Very often patients report with attrition of premolar and molar because of inadequate disocclusion. In these situations alteration of canine position would change the existing occlusal plane determined as curve of Spee. Occlusal plane analyser has long been used to assist the operator in the development of an initial mandibular occlusal plane in diagnostic casts and later as an integral part of both the contour of the definitive restorations[ 1 ]. It eliminates posterior protrusive interferences and helps to achieve plane of occlusion, which permits the anterior guidance to disclude posterior teeth without interferences. This study makes an effort to study on influence of variation of dimension of Anterior and Posterior survey lines (ASL and PSL) on the mandibular canine as well as rest of the posterior dentition.
