Brief summary

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.

Interventions

PROCEDUREFibReORS with apically positioned flap (apical position)

Periodontal surgery including flap elevation. root surface scaling, bone remodeling and suture of the flap at 2 mm subcrestal position

PROCEDUREFibReORS with apically positioned flap (crestal position)

Periodontal surgery including flap elevation. root surface scaling, bone remodeling and suture of the flap at either a crestal 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.
