Optimization of Connective Tissue Graft Length by Graft Splitting: A Case Series.

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.
