Root Coverage for Single Deep Gingival Recessions: Outcomes Based on a Decision-Making Algorithm

Figure 1

Graphic illustration of the decision-making process. When the GM-VF distance is clearly greater than RD, CAF + CTG should be adopted. In borderline cases (gray color), CAF + CTG was adopted. When CAF is rejected, narrow recessions should be treated with DPE + CTG and wide recessions should be treated with LSF + CTG. The presence of compromising factors in narrow defects moves the decision towards LSF + CTG. In addition, 3-teeth length is recommended for CTG in the presence of compromising factors (see text for extended explanation). RD = recession depth; GM = gingival margin; VF = vestibule fornix; CAF = coronally advanced flap; DPE = double papilla envelope; LSF = lateral sliding flap; CTG = connective tissue graft; RW = recession width.
