Aim: The aim of this study was to evaluate the outcome of a soft tissue dehiscence coverage technique, at single non-submerged implant sites, presenting shallow isolated buccal mucosal recession. Material and methods:Sixteen patients were included in this prospective study. A connective tissue graft (CTG) was harvested from the maxillary tuberosity. The donor soft tissue was de-epithelialized and trimmed with a mucotome for an optimal adaptation to the collar of the implant.

These results confirm the possibility to successfully treat peri-implantitis lesions. There is lack of evidence of whether or not the resolution of the peri-implant disease is associated with the defect configuration. Due to the fact that complete resolution does not seem a predictable outcome, the clinical decision on whether implants should be treated should be based on several patient related elements.

For the maxilla there are no studies, at the present time, that can be utilized to address the question of how many implants should support an overdenture. For the mandible, it cannot be concluded that bone loss, patient satisfaction, or number of complications is significantly related to the number of implants supporting the overdenture. Furthermore, splinting two implants does not seem to offer additional value. Well conducted research is needed to identify the prognostic factors for long-term success.
