The influence of different soft-tissue grafting procedures at single implant placement on esthetics: A randomized controlled trial.

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