Cross-arch bar splint.

Abstract

This article describes the use of a round bar connector that will aid the preservation of bone support for two isolated mandibular canines when a fixed partial denture replacing the anterior teeth is contraindicated. If the removable partial denture is constructed with only the two lone-standing canines as abutments, the removable partial denture will move occlusally and gingivally during function, thereby generating forces that may cause bone loss. By the addition of a straight round bar connecting the two canine crowns, the abutments are splinted together and masticatory forces are directed along the long axes of the teeth.
