Abstract
Patient: An edentulous female complained of masticatory dysfunction. The mandibular residual ridge was observed severe resorption. The case was diagnosed as decreasing the occlusal vertical dimension and losing the retention and stability of mandibular complete denture. The occlusal vertical dimention was increased in new denture, and the position of artificial tooth arrangement and shape of the polished surface were determined using the flange technique.
Discussion: The border movement of mandible had expanded on gothic arch tracing and the mandible position changed to postero-inferio position compared to that before treatment by analysis of lateral cephalograms, due to an increase in the occlusal vertical dimention. It was considered that masticatory dysfunction was improved by gaining the retention and stability of mandibular complete denture.
Conclusion: Fabrication of a new denture with an appropriate occlusal vertical dimension and using the flange technique achieved a favorable prognosis in this case.
