Abstract:
To evaluate the outcomes of an apically repositioned flap (ARF) plus xenogeneic collagen matrix (XCM) in augmenting keratinized mucosa width (KMW) around dental implants when compared with ARF plus free gingival grafts (FGG). Materials and methods Twenty‐six participants with at least one site with KMW ≤2 mm were randomized into FGG or XCM group. Clinical examinations were performed at baseline and at 2 and 6 months after surgery, including KMW, keratinized mucosa thickness, gingival index (GI), and probing depth (PD). Post‐operative pain and patient satisfaction were also evaluated. Results At 6 months, FGG attained a greater increase of KMW and thicker mucosa than XCM (4.1 ± 1.6 mm vs. 1.8 ± 1.0 mm, p 〈 .001; 1.7 ± 0.6 mm vs. 1.2 ± 0.3 mm, p 〈 .01). Regarding GI, PD, post‐operative pain, aesthetic outcomes, and patient satisfaction, no significant difference could be detected. Moreover, the operation time of XCM group was shorter (60 ± 9 min vs. 39 ± 8 min, p 〈 .001). Conclusions FGG could result in greater increase of KMW than XCM, though both could increase KMW, maintain peri‐implant health, and attain comparable aesthetic outcomes. The use of XCM was associated with reduced operation time.
