Enhancement of partial denture stability and load bearing capability to relieve abutment teeth by means of altered cast technique

Abstract

Patient: A 67-year-old male patient visited the hospital with the chief complaint of maxillary anterior teeth mobility and difficulty of mastication and was diagnosed as having cosmetic disturbance and dysmasesis owing to the inadaptation of dentures. Immediate placement of dentures restored the esthetics and masticatory function, and the occlusal support was restored by repairing the mandibular dentures. Good long-term prognosis was achieved by definitive dentures using the functional impression and altered cast technique.

Discussion: It is thought that a functional impression controls the depression of the denture base, stabilizes the dentures, and reduces the load on abutment teeth.

Conclusions: In this case, the partial dentures restored the esthetics and masticatory function, and the functional impression by the altered cast technique reduced the load on abutment teeth, and increased the long-term stability of the dentures.
