Biologically Guided Flap Stability: the Role of Periosteum Retention on the Performance of the Coronally Advanced Flap

Aim: to evaluate the possible benefit on wound healing and flap stability of periosteum inclusion, comparing a "split-full-split" thickness flap elevation versus a "split" thickness approach performed during CAF for the treatment of isolated-type gingival recessions in the upper jaw. Material and Methods: forty patients were randomized, 20 were treated with "split-full-split" (test group) and 20 with a "split" approach (control group). Analyzed parameters at 1 year were: CRC, percentage of Recession Coverage (RC), Keratinized tissue (KT) gain, patient-related outcome measurements.
