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.
