Int J Oral Maxillofac Surg. 2020 Dec 02;: Authors: De Angelis P, De Angelis S, Passarelli PC, Liguori MG, Pompa G, Papi P, Manicone PF, D'Addona A Abstract Dental implant placement is a predictable therapy for replacing teeth. Nevertheless, mechanical, biological, and aesthetic complications frequently occur. The aim of this study was to compare the clinical outcomes of a xenogeneic collagen matrix (XCM) used at the time of implant placement as an alternative to a subepithelial connective tissue graft (SCTG), for soft tissue augmentation. This was a prospective clinical trial with 12 months of follow-up. In the control group, soft tissue augmentation at the time of implant placement was performed with a SCTG, while in the test group, a XCM was employed. At 12 months postoperative, all xenografts showed no postoperative complications. In both groups, a significantly greater thickness was observed on the buccal and occlusal sides from preoperative to 3 months postoperative (P<0.05). No statistically significant difference in pink aesthetic score (P=0.379, 6 months postoperative) or marginal bone loss (P=0.449 at 3 months postop erative, P=0.778 at 6 months postoperative) was observed between the groups. Statistically significant differences in pain perceived by the patients (P<0.0001) and the time to complete the surgical procedure (P=0.0008) were detected. At 12 months after surgery, XCM provided similar clinical results in terms of soft tissue augmentation on the buccal and occlusal sides as compared with the SCTG.
