Narrow-Diameter Implants: Dual Function as a Tent Pole for Vertical Ridge Augmentation and a Guide for Definitive Implant Position.

Vertical bone defects present a challenge for the placement of implants in sufficient bone with proper position for a successful treatment outcome. This case report describes the use of a narrowdiameter (2.2 mm) implant as a tent pole for guided bone regeneration and documents the vertical bone augmentation achieved. In addition, following removal, the narrow-diameter implant served as a guide for the proper positioning and angulation of the final implant and its supporting restoration. The protocol and step-by-step procedure are described.
