Guided tissue regeneration. A status report for the American Journal of Dentistry.

This report reviews clinical results which have been obtained with guided tissue regeneration (GTR) using non-resorbable and resorbable materials. The report highlights the clinical factors that affect and that should be considered in order to improve the predictability of the results obtained after GTR. The indications for GTR procedures are reviewed and the surgical technique is described. The importance of periodontal maintenance, and the significance of adjunctive therapies in GTR procedures are also discussed. Based upon the vast scientific information and clinical experience with GTR, it can be stated that with the use of either resorbable or non-resorbable materials a new attachment, determined both clinically and histologically, will be promoted providing that the principles of GTR are properly implemented.
