OBJECTIVES:
The aim of this study was to evaluate the 5-year clinical and radiographic outcomes following reconstructive therapy of peri-implantitis lesions using mineralized dehydrated bone allograft and resorbable membrane in the nonsubmerged mode of wound healing.

Gellan gum-based hydrogels display limited cell adhesion ability due to the absence of cell-anchorage points usually present in proteins found in the extracellular matrix (ECM). This issue limits their use in the biomedical field as scaffolds to promote tissue repair. Our work addresses this challenge by investigating the use of polydopamine (pDA) as a bioactive layer to improve the surface and biological properties of gellan gum-based hydrogels cross-linked using carbodiimide chemistry.
