Abstract
ABSTRACT Introduction The aim of this case series was to assess the feasibility of a graft modification to increase its length when treating multiple adjacent gingival recessions with only one harvesting site at the palate and respecting the safety zone. Case series Nineteen recessions were treated in four consecutive patients with a modified coronally advanced tunnel and a modified connective tissue graft. An 8-mm height connective tissue graft was harvested by the single-incision technique, the graft was split longitudinally, achieving 4-mm height and double the length. Changes in recession depth, keratinized tissue height, mean and complete root coverage, and esthetic score were analyzed at 6 months. The technique allows to harvest a connective tissue graft up to 58-mm length with a single palatal site. Complete root coverage was achieved in 15/19 recessions (78.94%), with a mean root coverage of 82.90%. The mean recession depth was reduced by 1.31 mm and the keratinized tissue increased by 0.69 mm. The esthetic outcome score was 9.26/10. Conclusion This graft modification technique allows increasing significantly the graft length up to 58 mm without any modification of the surgical harvesting procedure. Therefore, it can be suggested to reduce the morbidity.
