Subepithelial connective tissue graft (palate) at implant placement vs No augmentation

Marginal bone level change · Partially edentulous patients receiving posterior mandibular implants

Subepithelial connective tissue graft (palate) at implant placement showed no clear difference in peri-implant marginal bone level change compared with no augmentation; GRADE not reported.

Subepithelial connective tissue graft (palate) at implant placement vs No augmentation

Aesthetic preference evaluated by the patient (split-mouth design studies) · Partially edentulous patients receiving posterior mandibular implants

Subepithelial connective tissue graft (palate) at implant placement led to lower patient preference (aesthetics evaluated by patients) compared with no augmentation; GRADE not reported.
