Gingival grafting – namely pedunculated, connective tissue or subepithelial connective tissue grafts - allows to treat Marginal Tissue Recessions (MTR) in an effective and rather predictable way according to the analysis of the initial situation and the chosen technique. Some specific procedures allow to increase gingival thickness and/or the height of keratinized tissue.
Many techniques require a donor site which is generally the palate or the maxillary tuberosity area.
To limit post-operative morbidity due to graft harvesting, biomaterials are used on one hand to increase gingival thickness, thus allowing to modify the periodontal biotype during the treatment of MTR, and on the other hand to increase the height of keratinized tissue. Finally, biomaterials are also tested to regenerate periodontal attachment.
