A case report of restoring masticatory function in an edentulous patient with crossbite arrangement

Abstract

Patient: A case report of restoring masticatory function in a patient with crossbite is described. The patient was an 80-year-old man who complained of masticatory disturbance caused by instability of complete dentures during mastication. This was caused by improper positions of artificial teeth and so the patient was given new dentures with a crossbite arrangement to improve the mechanical stability of the dentures.

Discussion: At first, preliminary jaw registration was recorded in this case to clarify whether the jaw relation was an indication of crossbite arrangement. In addition, the horizontal jaw position was determined by using Gothic arch tracing, and a functional impression was taken to attain good stability and retention, which led to high patient satisfaction.

Conclusion: It was useful to provide a crossbite arrangement for unstable maxillary dentures during use.
