Bone grafting techniques are used in many fields of surgery including trauma surgery, periodontal surgery and maxillofacial surgery. The need to replace bone lost in chronic disease, infection or trauma is clear, and the field has expanded considerably since substitutes were first used to supplement or replace autologous or allogeneic bone grafting. Recently the use of potent local factor or mesenchymal cells with or without different bone substitute was available clinically to be use during regeneration procedures. .As a result, the number of choices continues to increase as new materials are developed and are offered with combination of local factors and/or mesenchymal cells. However, the rationale for selection of one material over another or combination of the bone substitute with local factors and mesenchymal cells is not yet clear in many clinical situations. This is in part due to the lack of information on basic bone biology as it applies to implant materials in general, and to a particular clinical application.

The purpose of the presentation is to introduce the variety of bone graft materials currently available, discuss some of the new materials under development, and provide a biological rationale for the outcome when these materials are used clinically in Oral surgery. The use of local factors, mesenchymal cells in combination with different bone substitutes will be presented with their biological rationale and clinical application and success.

The rational to use block or particulate allographs in comparison to autograph will also be discussed.
