Influence of Flap Position on Soft Tissue Regrowth, Keratinized Tissue Increase and Postoperative Discomfort Following Fibre Retention Osseous Resective Surgery (FibReORS): a 6-month Split-mouth RCT With Multilevel Analysis.
Influence of Flap Position on Soft Tissue Regrowth, Keratinized Tissue Increase and Postoperative Discomfort Following Fibre Retention Osseous Resective Surgery (FibReORS): a 6-month Split-mouth RCT With Multilevel Analysis.
There is lack of data in literature on keratinized tissue increase after FibReORS in relation to primary flap position. This study has been designed as a split-mouth randomized trial to assess the influence of flap position after FibReORS. 16 patients were recruited and treated. The placement of the flap 2 mm apically to the bone crest instead at the bone level would be a viable approach to increase KT width without delaying wound healing. The extent of post-operative discomfort/pain was not influenced by primary flap position.
Inclusion Criteria:
1) diagnosis of severe chronic periodontitis (corresponding to grade III or IV according to the actual classification); 2) good general health; 3) full-mouth plaque score (FMPS) and full-mouth bleeding score (FMBS) < 20%; 4) at least two contralateral sextants with residual PDs of > 5 mm and persisting bleeding on probing (BoP) at posterior natural teeth 3 months after the completion of cause-related therapy
Exclusion Criteria:
1) pregnancy and lactation; 2) smoking > 10 cigarettes/day; 3) intake of antibiotics in the previous 6 months. In addition, teeth with degree II or III mobility, horizontal bone loss higher than 1/3 of the root length or designed as abutment for prosthetic rehabilitation were also excluded from the study.
