PARTICULATE XENOGRAFT VERSUS CONNECTIVE TISSUE GRAFT IN A LABIAL SUBPERIOSTEAL POUCH AROUND IMMEDIATE DENTAL IMPLANT: A RANDOMIZED CLINICAL AND RADIOGRAPHICAL STUDY

Abstract

Immediate dental implant placement offers a shorter treatment time and reduced number of surgical interventions. Additionally, it minimizes the marginal mucosal recession and promotes esthetic outcomes. The esthetic results of an implant supported prosthesis depend on the shape and texture of the soft tissues. Soft tissue recession is among the most common problems encountered in anterior implants. Many studies have reported that the gingival biotype is a diagnostic key for the esthetic success of implants as thick gingival tissue can significantly prevent crestal bone loss around implants and thin gingival tissue may lead to marginal bone loss during the formation of biologic width around implants. It is clear that the assessment of the soft tissue at the implant site is as important as the hard tissue status. Therefore, the transformation of the thin biotype to thick biotype is necessary to improve the esthetic outcomes of the immediate dental implant. Many authors have recommended the use of sub-epithelial connective tissue graft (SCTG) to thicken the soft tissue around the dental implant.
