The present randomized clinical trial aims at investigating two approaches (autogenous connective tissue graft vs acellular dermal matrix + enamel matrix derivative) when performed for vertical soft tissue augmentation at sites with peri-implant soft tissue dehiscences. Clinical, volumetric, ultrasonographic, and patient-reported outcomes will be evaluated at different time points up to 1 year.
