[Guided bone augmentation in edentulous areas]

Abstract

The use of autogenous onlay blocks placed together with self-tapping implants can achieve an excellent long-term success rate of individual implants. Autogenous bone chips or deproteinized bovine bone can be used to deal with fenestration and dehiscence defects when used in combination with e-PTFE membranes. The role of DFDBA as space maintainer under barrier membranes cannot be ignored. In most cases PTFE membranes are used because they offer reliable results. The use of a collagen membrane when supported by a bone substitute to maintain space gives good results, although long-term research is required. The future will be however tissue engineering. The principle is that a matrix, carrying stem cells and biological mediators like growth factors, is used. More research involves the use of human stem cells responsible for regeneration of different human tissues.
