“…In a more recent study a xenogenic collagen matrix was used instead of a subepithelial connective tissue graft but no significant recession coverage could be achieved . These results are in line with findings from a randomized controlled clinical study comparing the treatment of multiple adjacent gingival recessions by means of the modified coronally advanced tunnel technique in conjunction with either a subepithelial connective tissue graft or a xenogenic collagen matrix.…”

“…However, the clinical consequences related to the increase in the probing pocket depth are yet unclear. The reduction of the probing pocket depth following surgical intervention was only found in one study . This might be due to the treatment approach using the xenogenic collagen matrix that failed to cover the peri‐implant soft tissue recessions and resulted in soft tissue shrinkage.…”

Facial peri-implant mucosal recessions represent an increasing complication in implant dentistry and may negatively affect the esthetic outcome and patient satisfaction. The aim of the present paper is to provide a review on the potential causes of facial peri-implant mucosal recessions and to provide a rationale for treatment along with possible treatment options. The available data indicate that soft tissue augmentation around dental implants is possible, but at present there is no evidence demonstrating that the augmented soft tissues are able to influence the peri-implant bone levels (e.g. to limit peri-implant bone loss). Therefore, the rationale to cover or correct peri-implant mucosal recessions are (i) to optimize the possibility for performing an adequate level of oral hygiene, and (ii) to improve esthetics. At present, there is very limited evidence supporting any specific treatment modality for covering peri-implant soft tissue recessions. The limited available data indicate that only shallow peri-implant mucosal recessions (e.g. up to 2 mm) may be treated successfully by means of a coronally advanced flap and subepithelial connective tissue graft or with guided bone regeneration, while no data are available supporting the possibility of covering deep and large peri-implant mucosal recessions.

“…In particular, because of its composition (dense connective tissue rich of collagen fibers with low amount of fatty and glandular tissue) and its characteristics (stability and firmness), the CTG derived from the de‐epithelialization of a free gingival graft can be considered the material of choice . Alternatively, graft substitutes, such as collagen or acellular dermal matrices have also been used for increasing the tissue thickness with promising results . In the presence of weak papillae, despite the correct position of the gingival margin (Class Ib), increasing the interproximal soft tissue though crown removal and abutment reduction is strongly suggested.…”

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.

Soft-tissue dehiscence at the facial aspect of an osteointegrated implant is a common complication which impacts on the final esthetic result. The etiology and ways of diagnosing this condition are still controversial. Many factors seem to influence the position of the peri-implant soft-tissue margin, and some of these have been studied more carefully than others. Various surgical and combination surgical-prosthetic approaches have been described to treat soft-tissue dehiscence, with the latter appearing to be more predictable. This paper focuses on the factors affecting peri-implant soft-tissue margins and describes the different treatment approaches, reported in the literature, to treat buccal soft-tissue dehiscence, with more focus on the prosthetic-surgical-prosthetic approach.
