Background: Soft-tissue grafting to thicken the soft tissue around dental implants was proposed to ameliorate the esthetic outcome. Traditionally, connective tissue is used as a grafting material, but a xenogeneic collagen matrix was introduced as an alternative to reduce patient morbidity.
Methods: A total of 60 patients randomly received either no graft (n = 20, NG group), a connective tissue graft (n = 20, CTG group), or a xenogeneic collagen matrix (n = 20, XCM group) when an implant was placed in a preserved alveolar ridge. Changes in mid-buccal mucosal level (MBML) at 1 (T-1) and 12 (T-12) months after final implant crown placement were compared to the pre-extraction level. Additionally, esthetics, marginal bone level, clinical peri-implant parameters, and patient satisfaction were assessed.
Results: At T-12, mean changes in MBML were -0.48 +/- 1.5 mm, -0.04 +/- 1.1 mm, and -0.17 +/- 1.3 mm in the NG, CTG, and XCM groups (P = 0.56), respectively. Regarding the other outcome variables, no significant intergroup differences were observed.
Conclusions: Soft-tissue grafting at single implant placement in preserved alveolar ridges does not result in a better esthetic outcome or in better peri-implant health and should not be considered as a standard procedure.
