A case report: Improved masticatory disorders with reduced prosthetic space using a removable partial denture with zirconia framework

Abstract

Patient: A 45-year-old man presented to the clinic with a complaint of difficulty in chewing due to dental caries. The maxillary right central incisor and mandibular right and left lateral molars had residual roots due to caries, and the functional cusp of the maxillary right and left lateral second molars was in contact with the mandibular ridge at the intercuspal position. Improvement of masticatory disorders was achieved by using a partial denture in which the mandibular anterior tooth incision and the posterior occlusal surface were covered with a zirconia framework to increase the occlusal height and correct the occlusal plane.

Discussion: Correction of the occlusal height and occlusal plane with a partial denture resulted in an improvement in masticatory disorders and an increase in maximum occlusal force.

Conclusion: A partial denture with a zirconia framework effectively improved masticatory disorders associated with reduced vertical prosthetic zone by improving masticatory function.
