Horizontal Ridge Augmentation and Contextual Implant Placement with a Resorbable Membrane and Particulated Anorganic Bovine Bone-Derived Mineral

Ferdinando Attanasio et al. Case Rep Dent. .

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.

Occlusal view (i) of the posterior mandibular area 6-months postsurgery. Occlusal view (j) of the regenerated bone. Second surgery performed by a lingual approach with roll flap technique that allows to increase the vestibular volume of soft tissues. (k) Healing screw in place. (l) Removal of healing screws and taking impressions. (m, n) Placement of the definitive crown (screw-retained).
