Bone regeneration with resorbable and non-resorbable membranes

OBJECTIVES. TO analyze the biological principles of guided bone regeneration and to provide the clinician with information regarding the use of different membranes. MATERIALS AND METHODS. The choosing criteria among different membranes and the clinical options are presented. Finally, the surgical technique is described in details. RESULTS AND CONCLUSIONS. Guided bone regeneration is one of the several surgical techniques that have been introduced in the last two decades for bone regeneration prior or at the time of implant placement. The rationale of this technique is the positioning of a barrier membrane between the bone and the connective tissue to create a secluded space and to enhance the proliferation of bone forming cells.
