Full versus partial thickness flap to determine differentiation and over keratinization of non‐keratinized mucosa. A 3‐year split mouth randomized pilot study

Abstract Objectives It was shown, that Connective Tissue Grafts (CTG) retrieved from the tuberosity tends to determine hyperplastic responses and may induce a beneficial over‐keratinization of non‐keratinized mucosa. Clinically evaluate and compare CTG from tuberosity ability to increase soft tissue...

Clinically evaluate and compare CTG from tuberosity ability to increase soft tissue thickness and the keratinization potential after recipient area is either prepared using split or full thickness flap in edentulous mandible. Materials and methods Fourty implants were placed in 10 edentulous patients with atrophied mandible (Class IV of Misch) presenting less than 1.0 mm of keratinized tissue using a flapless approach and immediately restored with acrylic temporary bridge on multi‐unit abutments. The surgical sites were split‐mouth randomized and prepared as CTG recipients by a tunneling procedure. Twenty benefited of a partial thickness approach and 20 of a full thickness one. The CTG was placed buccally using partial thickness or full thickness flap according to the randomization schedule. The width of keratinized tissue (KT), the horizontal soft tissue thickness (STT), the marginal hard and soft tissue levels as well as the implant success parameters were collected and analyzed. Results After a 3 year follow‐up period the increase of KT was statistically significantly (p < 0.001) larger in the partial thickness group from 0.6(0.6) to 5.1(0.72) mm, while full thickness group showed very little improvement from 0.5(0.51) to 1(0.57) mm (p < 0.001). STT was significantly increased in both groups over time: from 2.4(0.88) to 5.4(0.68) mm in full thickness group and from 2.5(0.51) to 5.8(0.41) mm in partial thickness group without any significant difference between the groups. Conclusion The increase of soft tissue thickness by using CTG from tuberosity was found in both groups, while keratinization of non‐keratinized mucosa appeared more in the partial thickness group.Algirdas PuisysViktorija AuzbikaviciuteEgle Vindasiute‐NarbuteSaulius ZukauskasDainius RazukevicusMichel M.
