Guide the tissues for periodontal regeneration (gtr): a review

To restore periodontal tissues that are lost through disease or trauma is the very rationalae of periodontal treatment. Guided Tissue Regeneration (GTR) technique has been applied for treating periodontal defects such as intrabony defects, furcation involvements. Outlook of periodontal regeneration has changed by incorporation of GTR concept and GTR membranes. Membranes are of several types used for regeneration. The concept that the fibroblasts from the periodontal ligament or undifferentiated mesenchymal cells can re-create the original periodontal attachment is well applied here. Clinically this is accomplished by placing a barrier over the defect thereby excluding gingival tissues from the wound during early healing. There are two 2 types of membranes: Non absorbable and Absorbable membranes. There is a necessity to remove non absorbable membranes for which second surgery is needed, so these are occasionally used now. Absorbable membranes need not be removed so are used frequently. This paper reviews briefly about the GTR membranes, its uses for various periodontal defects and the predictability of a successful treatment outcome.
