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.

Multitier Technique for Bone Augmentation Using Intraoral Autogenous Bone Blocks
Brånemarket al1 originally described autologous bone grafts used with dental implants,and they are now a well-accepted procedure in oral and maxillofacial rehabilitation. Placement of an end osseous implant requires sufficient bone volume for complete bone coverage.Further-more,the patter no fridge resorption ,which contributes to a nun favorable maxillo mandibular relationship,requires angulation of the implant and/or angled abutment,and affects the proximity of adjacent facial concavities (maxillary sinus,nasal cavity)and vital structures(mandibular nerve).

Immediate Implant Placement into Extraction Sockets with Labial Plate Dehiscence Defects: A Clinical Case Series

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.

Management of Narrow and Short Ridge Dimensions in Implant Dentistry: New Minimally Invasive Concepts
The management of narrow and short ridge dimensions has posed a great concern for most implantologists. Often large GBR or block augmentation procedures are suggested with high morbidity but this lecture presents more minimally invasive options to restore these ridge challenges. Ridge Expansion with motorized drills as well as the utilization of ultra-short and wider implants to avoid sinus and nerve proximity challenges will be discussed. The role of blood born bioactive modifiers, specifically PRGF (Plasma Rich in Growth Factors) to enhance wound healing will similarly be highlighted.

Bone Graft Solutions in the Treatment of a Defective & Deficient Ridges; Advantages of Combined Therapy
More patients are treated with implants than ever before. Unfortunately, many have insufficient bone available to support an implant prosthesis. This presentation describes the utilization of several different augmentation approaches for the severely resorbed ridge and dentally handicapped fully endentulous patient. Current concepts related to autogenous bone harvest, 3D bone augmentation combined with blood born bioactive modifiers and digital planning are defined. Video and high resolution images are utilized to further describe these approaches.

Immediate Implants: Partial / Full Arch Rehabilitation & GBR - Part 2 Premium Member Content

Immediate Implants: Partial / Full Arch Rehabilitation & GBR - Part 2
By scientific studies produced in recent years has been confirmed, in selected cases, the validity of the post-extraction implants. The use of this method implies a lower emotional impact, a single surgery and a healing often better for the patient. We will be discussed traumatic extraction methods, perfect insertion of the implants with or without bone regeneration with bone substitutes and membranes and the opportunity to combine an advanced method as immediate implant with the execution of an immediate loading to restore aesthetics in more complex cases.
