DESIGN CONCEPTS OF A REMOVABLE PARTIAL DENTAL PROSTHESIS WITH IMPLANT-SUPPORTED ABUTMENTS

A clinical report is presented that describes the restoration of a severe anterior maxillary ridge defect and pneumatized sinuses with a rotation-path partial removable dental prosthesis and implant-supported abutments. Other treatment options were considered and rejected based on patient preferences and limitations, which included avoiding invasive surgeries. The principles of integrating fixed and removable prosthesis design were applied. However, the clasp design was modified to take into account the direct bone-to-implant contact of the abutments. An esthetic and functional outcome was obtained without any overly invasive surgery. (J Prosthet Dent 2014;112:99-103)
