The combination acid-etch--retained splint in fixed precision complete-coverage partial denture abutments.

A case report involving a 50-year-old woman with the six mandibular anterior teeth remaining is used to demonstrate a combination restoration that utilizes a fixed partial denture as abutments for a removable partial denture. Traditional complete- coverage porcelain-fused-to-gold distal abutments are used with extracoronal precision attachments on the distal-most abutments. These are connected to each other using a modified dovetail, coronal, etched-metal lingual splint. A Class II bilateral removable partial denture is used to replace the missing posterior teeth. Four additional abutments are provided without compromise of esthetics, and reduction of healthy tooth structure is minimal.
