The safety of bone allografts used in dentistry
Recent media reports concerning “stolen body parts” have shaken the public’s trust in the safety of and the use of ethical practices involving human allografts. The authors provide a comprehensive review of the safety aspects of human bone allografts.

Buccal Plate Regeneration with Immediate Postextraction Implant Placement and Restoration: Case Reports
In these reports, buccal bone plate regeneration was obtained through a flapless approach and immediate postextraction implant placement with a cancellous bone and collagen graft in the buccal gap.

Alloplastic Bone Substitutes Around Dental Implants
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…

Controlled Ridge Splitting (CRS)
To demonstrate a new technique of controlled ridge splitting (CRS) in severely atrophied maxillary cases as an alternative to autogenous block graft. Twenty cases were completed using a controlled ridge splitting (CRS) technique with a total of 65 implants were placed in severely atrophied Maxillae and followed after the implants were loaded.

A Clinical Update in Bone Regeneration: Autogenous Bone vs. BMP-2
For historical and biological reasons autogenous bone has long been considered the gold standard of bone graft materials. For bone augmentation procedures autogenous grafts provided predictable volume gains, favorable bone quality with short healing periods. However, the need to harvest the graft and associated morbidity are inherent disadvantages. The choice of a technique for bone augmentation is dependent on a number of factors including the use of bone substitutes. More recently recombinant human bone morphogenetic protein (rhBMP-2) has been shown to be effective in repairing buccal wall defects from extractions and in sinus bone grafting. The use of rhBMP-2 is currently under clinical investigation as a replacement for autograft in ridge augmentation process.

The mIVAN Approach for Preservation Surgery
mIVAN* Technique is a nice abbreviation for complicated terminus: “ Modified Interpositional Augmentation Neogenesis”. It is basically simultaneous hard and soft tissue augmentation utilizing pediculated connective tissue graft. It works for Socket type 2 and 3 and ridges with horizontal atrophy. Combined with Partial Extraction Therapy, mIVAN technique is a nice treatment choice for the teeth with recessions. 

Current Concepts for the Preservation of the Post-Extraction Alveolar Ridge
After tooth extraction, bone resorption of varying amounts always occurs as the edentulous site of the alveolar process undergoes both qualitative and quantitative changes. Different techniques have been presented in literature in order to preserve the post-extraction site, including the use of barrier membranes, tri-dimensional matrix and bone fillers. An “open-healing” approach is nowadays commonly used, combining a proper management of soft tissues with biological integration of biomaterials. Once hard tissue has been successfully augmented, an adequate soft tissue thickness becomes mandatory in order to create healthy and stable peri-implant tissues. An innovative volume-stable collagen matrix provides the opportunity to treat soft tissue defects around implants as an alternative to connective tissue graft.

Esthetic Zone Reconstruction: Synergy of Hard and Soft Tissue Grafting
The loss of alveolar ridge contour in the esthetic zone compromises both esthetics and function. This clinical presentation will focus on the application of both hard and soft tissue grafting in the esthetic zone implementing state of the art interactive CT diagnosis and treatment planning for optimal esthetic implant reconstruction. Emphasis will be on indications, graft and harvest site assessment, timing, and use of bioactive modifiers including BMP, PRGF and PDGF. The surgical protocol utilizing allogeneic and autogenous grafts in conjunction with connective tissue grafts, acellular dermis matrix, and related soft tissue procedures to avoid functional and esthetic pitfalls will be featured. Pre and post-grafting prosthetic workup, interactive CT graft assessment and perio prosthetic driven implant planning, stent driven implant placement, and computer milled abutment fabrication including guided surgery will be included.

The Modern Age of Regeneration: Tenting, Fixating and Space Creation
Regeneration requires a common biological thread for predictable results. Space Maintenance, Graft Stability, Bone Biologics, and Wound Management. This presentation will describe the importance of each critical step in regeneration and introduce a new technical system to assist the surgeon in managing and stabilizing the space required for optimal bone regeneration. Flap design, release, biologics selection and enhancement as well as bone stabilization, fixation, and secure membrane adaptation will be further highlighted as to it's critical value in the final results.
