title: Ring Rest Seat Design for Severely Tilted Molar Abutment Tooth: An Alternative Option.
abstract: A ring rest was used for a buccally inclined distal third molar, which served as an abutment for a distal extension Kennedy class II removable partial denture (RPD). This report describes in detail the ring rest design, which offers a conservative treatment option while complying with RPD principles. The design also allowed use of existing occlusal contact on the maxillary third molar without resulting in an overcontoured clasp design. Preparation technique for the rest, along with rationale for selection and design, is discussed. The need for other adjunctive treatment options was also avoided by using the inclination of the maxillary third molar, thereby providing a conservative, cost-effective, and time-efficient alternative treatment.
