Polyurethane and PTFE membranes for guided bone regeneration: histopathological and ultrastructural evaluation.
OBJECTIVE The purpose of this study was to research a membrane material for use in guided bone regeneration. STUDY DESIGN In this study, 25 male Wistar rats were used to analyze the biocompatibility and degradation process of biomembranes. The morphological changes in subcutaneous implantations were assessed after 7, 14, 21, 28 and 70 days. The materials were made of polyurethane polymer (AUG...
متن کاملGuided bone regeneration: A literature review
Guided bone regeneration (GBR) is a reconstructive procedure of alveolar ridge using membranes. This procedure is indicated when there is no sufficient bone for implantation, or in the case of optimal implant installation for esthetic or functional needs. GBR can be performed before implant placement, when there is not enough bone for initial stability of implants and less predictable outcomes ...
متن کاملGuided bone regeneration with subperiosteal implants of PTFE and hydroxyapatite physical barriers in rats.
Regeneration of periodontal and alveolar ridge defects utilizing membranes is a well-established procedure in reconstructive surgery. Biomaterial characteristics and membrane design employed in guided tissue regeneration (GTR) techniques play an important role in good results. The purpose of this histologic experimental study in rats was to compare the use of two physical barriers in the osteop...
متن کاملGuided bone regeneration (GBR) on healing bone defects: a histological study in rabbits.
In this study, the effects of guided bone regeneration (GBR) on the healing of bone defects were evaluated. Resorbable membranes were placed in experimentally formed cavities in the right posterior tibia of 30 rabbits. Decalcified histological sections were evaluated using optical microscopy at 10, 20, and 30 days after GBR. Osteocondrial bone union, active bone formation and spongiosal bone fo...
متن کاملVertical Guided Bone Regeneration using Titanium-reinforced d-PTFE Membrane and Prehydrated Corticocancellous Bone Graft
Guided bone regeneration (GBR) standard protocols call for filling the space underneath the membrane with autogenous bone or a mixture composed of autogenous bone particles and allogeneic bone tissue or heterologous biomaterials. This work describes the case of a GBR performed to restore a vertical bone defect with simultaneous placement of a dental implant in the posterior mandible that was ca...
