Vertical ridge augmentation with guided bone regeneration in association with dental implants: an experimental study in dogs

Abstract

The formation of even considerable amounts of bone following vertical ridge augmentation with GBR and implants was not accompanied by predictable osseointegration of the implants.

The Role of Bone Decortication in Enhancing the Results of Guided Bone Regeneration: A Literature Review

“…If a patient has a deficient ridge, a surgical procedure, referred to as guided bone regeneration (GBR), can be used to augment bone height and/or width 5 . Decortication of bone prior to placing a bone graft is often performed as part of a GBR procedure 6–12 . It is the intentional drilling of holes through the cortical bone into the cancellous bone or the removal of cortical bone to expose cancellous bone 13 .…”

Prospective assessment of post-extraction gingival closure with bone substitute and calcium sulphate

“…Many biocompatible materials have been used to try and correct the deformities of bone tissue caused by dental extraction, with the primary aim of creating an ideal situation for the placement of dental implants. Amongst these materials are autologous bone of intraand extra-oral origin, demineralised allogeneic bone, and several alloplastic materials, xenotransplants, bone substitutes and barrier membranes, with, in general, good clinical results (3)(4)(5)(6)(7). According to data from other authors, the non-use of graft material causes an average loss of bone matter of 4.4mm horizontally and of 1.2mm vertically after routine non-trauma dental extraction (8,9), although its use also has some drawbacks (it increases morbidity, cost and length of treatment) (1).…”

Cellular compatibility of a gamma-irradiated modified siloxane-poly(lactic acid)-calcium carbonate hybrid membrane for guided bone regeneration

“…To provide a suitable environment for the implant placement, guided bone regeneration (GBR), a bone regeneration technique, is used frequently in clinical dentistry 1,2) . GBR can support alveolar bone regeneration via the application of a biocompatible membrane [3][4][5] , which mechanically excludes surrounding soft connective tissue and maintains the space into which the desirable bone cells can migrate, thereby allowing the proliferation and differentiation of osteoblasts for bone formation. Critical criteria for ideal barrier membranes include biocompatibility, cell-occlusiveness, space-making function, tissue integration and clinical manageability 6) .…”
