Summary:

The repair of osseous defects has been a goal in dentistry for many decades. Subsequently, within the last several years, there has been an emergence of a new class of materials in dentistry referred to as synthetic bone. Finding the ideal bone substitute material has been the goal of researchers for many years. In attempting to achieve this ideal material, dental practitioners have tried with varying degrees of success: autogenous and demineralized freeze-dried bone, allografts of plastic, carbon and the apatite compounds. Most importantly, the practitioner shouId be cognizant that presently, autografts stiII represent the gold standard and provide excellent osteoconductive scaffolding, although they do require a harvesting procedure. The ideal goal of bone regenerative therapy is the reconstruction of alveolar bone that has been lost due to disease or atrophy. Bone grafting is one of the therapeutic modalities employed to fulfill this goal. The objectives of this additive procedure are the restoration of lost alveolar bone and possibly the regeneration of a functional periodontal attachment apparatus around teeth and bone around dental implants. This article discusses bone grafting materials and introduces a new bone substitute material which can be effective in both the regeneration of previously lost bone and the preservation of existing bone after extraction of diseased teeth.

Immediate Implant Placement into Extraction Sockets with Labial Plate Dehiscence Defects: A Clinical Case Series
To measure the buccal plate reconstruction of extraction sockets with labial plate dehiscence defects using a bone allograft in combination with an absorbable collagen membrane and a custom-healing abutment at the time of tooth removal. Implants placed into sockets with labial plate dehiscence defects demonstrated radiographic reformation of the labial plate dehiscence defect at 6 to 9 months post-treatment. The net gain in labial plate on CBCT in L1 and L2 was 3.0 mm, where 0 mm existed at pre-treatment. The minimum amount of labial plate thickness of 2.0 mm was achieved in all treated sites, evaluated radiographically at 6-9 months post-operatively, in a single procedure, without flap elevation and maintaining the gingival architecture and satisfactory esthetics.

Reconstruction of a Single-Tooth Traumatic Defect in the Anterior Maxilla Using the Khoury Bone Plate Graft

Reconstruction of a Single-Tooth Traumatic Defect in the Anterior Maxilla Using the Khoury Bone Plate Graft
Trauma to teeth and the dentoalveolar process may result in a ridge defect that precludes straightforward implant therapy of the patient. Typically bone and soft tissue augmentation of the area would first be needed to adequately prepare the tissues for the implant and its restoration..Grafting of the site is substantially more difficult in cases where the ridge also lacks adequate height, and techniques to recreate a bony envelope to apply guided bone regeneration may be required. Moreover, defects in the anterior aesthetic zone that require both bone and soft tissue grafting and a restoration that harmonizes the adjacent pink and white aesthetics may be an even more significant challenge to the restorative team. Hereafter a case of trauma to an anterior maxillary tooth that saw destruction of the ridge is presented, with the defect reconstructed to accommodate a functional and aesthetically pleasing implant supported restoration.

Physical And Chemical Properties Of Commercially Available Mineralized Bone Allograft

Physical And Chemical Properties Of Commercially Available Mineralized Bone Allograft
Bone graft materials are critical to the success of dental implants when there is a need to increase the volume of bone in a defect. The surface properties of these graft materials will have a profound impact on the outcome of the graft procedure. The clinician has many choices of bone graft substitutes when augmenting bony deficits. Allograft bone is the most widely used class of bone graft substitutes. Within this class there are a number of different bone allografts, which are manufactured utilizing widely varying processing techniques. There also appears to be a wide range of results in the published literature across the spectrum of different bone allografts. This in-vitro study evaluated chemical and surface properties of five different commercially available mineralized bone allografts.

Titanium Mesh and rhBMP-2 in Ridge Augmentation: Options and Limitations Premium Member Content

Titanium Mesh and rhBMP-2 in Ridge Augmentation: Options and Limitations
Titanium mesh has been used in reconstructive surgery and ridge augmentation for several years. The traditional technique involves using cancellous autogenous bone under the mesh scaffold. More recently growth factors and bone substitutes have been utilized as autograft replacements. There are several advantages to using titanium mesh for space maintenance including strength, ease of use, low cost and biocompatibility. However, the difficulty in removing the mesh has led to a search for other space maintenance scaffolds including tenting screws, dense preshaped collagen and porous high-density polyethylene. This webinar will discuss the use of rhBMP-2 for managing horizontal and vertical bone deficiencies with various scaffolds.
