Background: In this multicenter case series analysis, the authors present successful instances of 20 single-screw-retained and implant-supported prosthetic rehabilitation samples. Methods: A high-density heterologous dermal matrix (Derma® Osteobiol by Tecnoss, Torino, Italy) was employed with a specific technique named the matrix tissue graft (MTG) in all these cases characterized by an inadequate initial supra-crestal tissue height (thin if 1 mm or medium if 2 mm) to enhance the peri-implant soft tissues both vertically and horizontally. Results: The implants were deemed successful in all cases, yielding a success proportion of 100% (one-sided 97.5% confidence interval = 83.2–100%). The buccal and lingual gains were, respectively, 2.2 ± 0.38 mm (range 1.7–3.22 mm) and 0.83 ± 0.33 mm (range 0.1–1.5 mm). These measurements were calculated as the maximum distance between two superimposed.stl file models (derived from two different IOS devices) scanned before implant placement and 1 year after dermal matrix healing. Conclusions: An outstanding vertical and horizontal gain was obtained using this heterologous derma matrix placed above the bone crest and surrounding the dental implants.

Results: The implants were deemed successful in all cases, yielding a success proportion of 100% (one-sided 97.5% confidence interval = 83.2–100%). The buccal and lingual gains were, respectively, 2.2 ± 0.38 mm (range 1.7–3.22 mm) and 0.83 ± 0.33 mm (range 0.1–1.5 mm). These measurements were calculated as the maximum distance between two superimposed.stl file models (derived from two different IOS devices) scanned before implant placement and 1 year after dermal matrix healing. Conclusions: An outstanding vertical and horizontal gain was obtained using this heterologous derma matrix placed above the bone crest and surrounding the dental implants.
