Abstract

Alveolar ridge deficiency is considered a major limitation for successful implant placement. Various approaches have been developed to horizontal augmentation of bone volume. This case report presents the medium-term results of one-stage guided bone augmentation using an anorganic bovine bone (70%) and autologous bone (30%), placed in layers, in association with resorbable collagen membrane for a subsequent implant placement. The patient presented with a localized horizontal ridge defect in the posterior zone of the jaw. The clinical and radiographic presentations, as well as relevant literature, are presented.

Highlights

Over the years, prosthetic rehabilitations supported by osteointegrated implant has become a common treatment modality in daily dental practice
The use of a barrier membrane is a technique-sensitive procedure, and it is not lacking in complications [9]
The implant survival rate in the sites that have received GBR procedures through the use of xenogenic materials is greater compared to the sites that have received GBR procedures through the insertion of autogenous bone blocks; in a prospective study by Meloni et al (2019), data confirm the 1-year results allowing for the use of collagen resorbable membrane in GBR procedures for horizontal ridge augmentation; the two-stage approach needs a longer time before prosthesis delivery, this technique seems to be safe and predictable for large reconstruction and can be applied in daily practice [24]

Summary

Introduction

Prosthetic rehabilitations supported by osteointegrated implant has become a common treatment modality in daily dental practice. Surgeons used to decide to place implants where there was a sufficient amount of bone in order to ensure long-term success of osteointegrated implants This procedure could lead to two types of problems: an aesthetic and a mechanical one. GBR has been used for horizontal and vertical ridge augmentations and has demonstrated reproducible outcomes with high implant survival rates and low complication rates Both resorbable and nonresorbable barrier membranes have proven clinical effectiveness [3,4,5]. The most frequently reported problems involve the soft tissue; very often, the exposure of the membrane forces the operator to remove it with the possible compromise of the entire area subject to regeneration [10] This clinical case report details the successful use of an
