Background: The incidence of a peri-implant soft tissue dehiscence/deficiency (PSTD) is not a rare finding. Despite multiple previous attempts aimed at correcting the PSTDs, a classification of these conditions has not yet been proposed. This lack in the literature may also lead to discrepancies in the reported treatment outcomes and thus misinform the clinician or the readers. The aim of the present article was therefore to present a classification of peri-implant PSTD at a single implant site. Methods: Four classes of PSTDs were discussed based on the position of the gingival margin of the implant-supported crown in relation to the homologous natural tooth. In addition, the bucco-lingual position of the implant head was also taken into consideration. Each class was further subdivided based on the height of the anatomical papillae. Results: Subsequently, for each respective category a surgical approach (including bilaminar techniques, the combined prosthetic-surgical approach or soft tissue augmentation with a submerged healing) was also suggested. Conclusion: This paper provides a new classification system for describing PSTDs at single implant sites, with the appropriate recommended treatment protocol.

Abstract

Background: The incidence of a peri-implant soft tissue dehiscence/deficiency (PSTD) is not a rare finding. Despite multiple previous attempts aimed at correcting the PSTDs, a classification of these conditions has not yet been proposed. This lack in the literature may also lead to discrepancies in the reported treatment outcomes and thus misinform the clinician or the readers. The aim of the present article was therefore to present a classification of peri-implant PSTD at a single implant site. Methods: Four classes of PSTDs were discussed based on the position of the gingival margin of the implant-supported crown in relation to the homologous natural tooth. In addition, the bucco-lingual position of the implant head was also taken into consideration. Each class was further subdivided based on the height of the anatomical papillae. Results: Subsequently, for each respective category a surgical approach (including bilaminar techniques, the combined prosthetic-surgical approach or soft tissue augmentation with a submerged healing) was also suggested. Conclusion: This paper provides a new classification system for describing PSTDs at single implant sites, with the appropriate recommended treatment protocol.
