Autogenous Bony Halo for Ridge Augmentation and Simultaneous Implant Placement

Abstract

Tooth extraction often leads to alterations in the dimensions of the ridges. Hence it may be necessary to perform augmentation procedures before dental implants are placed. Various surgical procedures and materials have been introduced that enhance the soft tissue support and structural base of bone required by implants. Alveolar bone augmentation methods include guided bone regeneration onlay grafting interposition grafting distraction osteogenesis ridge splitting and socket preservation. The bone ring technique is another onestage procedure that is carried out to treat vertical alveolar ridge abnormalities. In this technique the dental implant and a block graft which can either be an autogenous graft or an allogenic cortico-cancellous graft are placed simultaneously. This case report describes the application of the bone ring approach for augmentation of the implant site along with the simultaneous placement of the dental implant. This is an easy procedure for obtaining ring-shaped donor bone for the three-dimensional 3D reconstruction of bone deformities.
