Technical Note on Root Coverage of Lower Anterior Teeth Using a Partially Deepithelialized Connective Tissue Graft (PE-CTG) Aided by a High-Speed Handpiece

Figure 4

(a) In a large recession defect, when the connective tissue is exposed without leaving the epithelialized portion, necrosis of the graft is observed at 1 week after the surgery. Complete coverage did not occur after 6 months. (b) When PE-CTG was performed in a case with a gingival recession defect 5 mm in depth, the epithelialized portion was sloughed and capillary ingrowth was observed in the underlying connective tissue 1 week after the surgery. Even after 6 months of surgery, complete root coverage was maintained.
