A case report of occlusal reconstruction using a removable partial denture for a patient with deep bite and scissors bite

Abstract

Patient: A 66-year-old male visited our hospital with the chief complaint of difficulty in mastication. A decrease of denture space due to missing bilateral mandibular molars that had been left untreated for a long time was observed. In addition, scissor bite and deep bite had developed due to the lack of occlusal support. Occlusal reconstruction by increasing the vertical dimension was performed by a splint-type treatment denture, and then the definitive prosthetic procedures were performed.

Discussion: A splint-type treatment denture was used for achieving adequate space for the prostheses. After it was confirmed that the patient had adapted to the new mandibular position, cap clasps were applied to maintain posterior occlusal support and deal with the high occlusal forces. Cap clasps have a high supporting function and resulted in a favorable outcome.

Conclusion: In a patient with scissor bite, a partial denture with cap clasps may be effective for reconstructing the occlusal plane and occlusal support without aggressive crown prostheses.
