Abstract

The management of fixed prosthodontics often necessitates the preparation of healthy abutment teeth, which can inadvertently disrupt their natural contours and contacts. This article addresses the challenges posed by abutment teeth that exhibit defects, such as recession or pathological migration, leading to improper interproximal contacts and potential food impaction. The application of guiding plane principles traditionally used in removable partial dentures (RPD) is adopted in fixed prosthodontics to establish optimal contacts in fixed partial dentures (FPD). The discussion emphasizes the importance of preserving the integrity of adjacent teeth during preparation while highlighting alternatives such as orthodontic correction and partial crowns for more pronounced tilting. The proposed method is minimally invasive, cost-effective, and time-efficient, making it particularly suitable for cases with mild tilts.
