This systematic review aimed to assess the effectiveness of xenogeneic collagen matrices (XCMs) and acellular dermal matrices (ADMs) in comparison to connective tissue grafts (CTGs) for the augmentation of oral mucosa around dental implants. MEDLINE and the Web of Science were searched for clinical studies that compared substitute materials for the augmentation of oral mucosa to the subepithelial connective tissue graft around dental implants during or after implantation. The review was conducted according to the recommendations of the PRISMA statement. From an initial search result set of 1050 references, seven articles were included in the review. The study designs were heterogeneous, so no meta-analysis could be performed. Both the CTG and either type of substitute material resulted in increased mucosal thickness. Four studies showed no significant difference, while three demonstrated a significant difference, favoring the CTGs over alternative materials. Soft tissue augmentation around dental implants is a safe procedure and leads to thicker mucosal tissue. The subepithelial connective tissue graft can still be regarded as the gold standard, but substitute materials may be an acceptable alternative in some situations, such as for pain-sensitive patients, among inexperienced surgeons, and for sites with an already thick biotype.

Bac kground:The principlegoal of orthognathic surgery is to establish a balanced and stable dento-skeleto facial complex. This mandates the surgeon and the orthodontist to be able to predict the soft tissue changes to the orthognathic surgery precisely, which is accurately possible using 3-D imaging. Aims: To evaluate the soft tissue changes following class III orthognathic surgery using 3-D imaging. Settings and Design: Systematic review. Methods and Material:This review was conducted according to Preferred Reporting Items for Systematic Reviews and meta-Analyses guidelines systematically searching the six databases including PubMed, Cochrane, Google Scholar, LILACS, Directory of Open Access Journals, and OpenGrey. Statistical analysis used:Not applicable. Results: This systematic review comprises of most UpTo Date evidence from eleven articles answering the review questions. Conclusion: Le Fort I advancement shows significant increase in the alar width, alar cinch, upper lip, chelion, labiale superius, crista philtri, pronasale and subnasale. Mandibular setback shows significant backward movement of soft tissue point B, labialeinferius and subnasale and chin.
