Technique & Long-Term Stability of Bone Graft and Soft Tissue Graft

Autogenous bone and sof t tissue graf ts are reliable. Mandibular cortical grafts and connective tissue grafts remain the gold standards in the restoration of intraoral tissue volume. They are convenient sources of grafting, allow for dense quality grafts, do not produce immune reactions, and are incorporated with a short healing period when compared with other methods of repair.

It should be noted that bovine bone itself is not a well-s tu di ed b one gr af t mate r ial f o r cr ani o f acial b one reconstruction. A close evaluation of published papers in favor of bovine bone reveals wide variation in study designs, creating conditions for erroneous conclusions from the methods used. Often, use of broad or vague definitions and errors in analytical models can be noted. An especially important recommendation is that the limited ability to screen prions within the animal genome, along with a long latency period to manifestation of the disease (1 to over 50 years) in infected patients, provides a framework for discussing possible long-term risks of the xenografts that are used so extensively in dentistry.

At this meeting surgical modalities aimed at enhancing bone and soft tissue structures will be presented. The amount of oral bone that can be safely harvested and the related techniques are analyzed.

LEARNING OBJECTIVES

1. Discuss techniques and the healing dynamics of the autogenous bone and soft tissue grafts

2. Explain the various factors affecting graft incorporation to achieve  an optimal outcome.

3. Complications and resolution
