Gain of keratinised tissue

The band of keratinized tissue around teeth and implants is considered to be important in maintaining functionality and esthetics. It also enables patients to maintain good oral hygiene without irritation or discomfort.1,2

The width of the keratinized mucosa around an implant might also influence the risk of peri-implantitis.3 This remains a controversial issue.4

Autogenous soft tissue grafts, such as free gingival graft or connective tissue grafts, have proven successful in creating additional keratinized tissue around teeth and implants.5 However, harvesting those grafts, usually from the palate, is painful, technically demanding, time consuming and may lead to complications such as bleeding, pain, swelling, and occasionally also numbness or infections.6-9

Several studies have shown successful outcomes with Geistlich Mucograft®. The collagen matrix creates the same amount of keratinized tissue as connective tissue grafts10 or free gingival grafts5,11 and helps to regenerate a keratinized tissue that resembles the surrounding native gingiva.12 Compared to autologous grafts the matrix produces a better color and texture match with the surrounding tissue that remains stable in the long term.13
