Papi P, Penna D, Di Murro B, Pompa G. Clinical and volumetric analysis of peri-implant soft tissue augmentation using an acellular dermal matrix: A prospective cohort study. J Periodontol. 2020. doi: 10.1002/JPER.20-0219. Online ahead of print.

Aim:
To report clinical and volumetric 3D changes in mucosal thickness (MT) 1 year after treatment with mucoderm® (botiss biomaterials).
Material/Methods:
In this prospective cohort study, soft tissue augmentation was performed in 12 patients at second-stage surgery in the premolar maxillary area. Mucosa thickness (MT) was assessed prior to implant placement and 1, 6, and 12 months following treatment. Digital linear and volumetric measurements were recorded at baseline and after 1 and 12 months. Furthermore, clinical parameters included Probing Pocket Depths, Bleeding On Probing, Plaque Index and marginal bone loss. Esthetic outcomes of treatment were evaluated objectively using the Pink Esthetic Score and through patient reported outcomes.
Results/Conclusion:
After 1 year a significant increase in MT was reported with a mean gain of 1.25 mm. Soft tissues remained stable, with no statistically significant differences between 6 months and 1 year. The use of mucoderm® at second-stage surgery was shown to be an effective procedure for peri-implant soft tissue augmentation.
