Management of Anterior Ridge Defect with Andrew's Bridge

Abstract

Residual ridge deformity after tooth loss is an expected outcome. The treatment of a patient with a history of trauma with loss of teeth and ridge defect is a significant challenge. This article presents a case of Seibert's class III ridge defect in the maxillary anterior region, which was treated with a fixed-removable system, the Andrew's bridge, for economical and time constraints. It requires a castable bar and sleeve attachment, which provides precision and retention while seating. It is primarily indicated where abutments are capable of supporting a fixed partial denture, but residual ridge shows severe loss.
