Biopolymeric membrane - a new concept in guided bone regeneration. Series of cases

Abstract

Introduction. Different types of resorbable and non-resorbable membranes, cortical autogenous and allogenic bone plates, and prefabricated and perforated titanium meshes are currently used as guidance and support materials. All these devices present a series of advantages, but also disadvantages, such as gingival dehiscence with exposure and superinfection, additional trauma, and complete resorption of the bone graft. The objective of the study. This study emphasizes the importance of resorbable biopolymeric membranes in GBR. The retrospectively and descriptive analyses of the technique at 6 months postoperative time on a series of cases were performed. Materials and methods. GBR with resorbable biopolymer mesh was performed in 15 patients in 18 graft sites. Was analyzed just graft sites without any complication. The density of the newly formed bone under the augmentation membrane was evaluated postoperatively at 6 months using computed tomography (CBCT) according to the Hounsfield scale. Results. Results were interpreted in 18 graft sites and were evaluated at 6 months by paraclinical CBCT examination. After the polymer mesh GBR procedure, the mean radiodensity of the new bone obtained in the 18 sites was 1805 HU and the radiodensity of the native cortical bone next to the bone graft was 1793.4 HU
