Abstract
Aim: This study evaluated the role of buccal pedicle flap technique compared to connective tissue graft for peri-implant soft tissue augmentation.
Materials and Methods: This study was a randomized controlled clinical trial including 21 implants that were placed in partially edentulous sites and were randomized at the second stage surgery after 3 months of implant placement as follows: group I (buccal pedicle flap), group II (connective tissue graft) and group III (control group). Clinical parameters including gingival thickness, keratinized mucosa width, pink esthetic score, gingival, and plaque index were measured at baseline and after one year.
Results: Gingival thickness, keratinized mucosa width, and pink esthetic score increased significantly in group II after 1-year follow-up compared to the two other groups followed by group I, which showed a significant increase in gingival thickness. Gingival index and plaque index decreased in the three groups after 1 year.
Conclusion: The buccal pedicle flap showed an increase in gingival thickness, so it can be used for soft augmentation around the implant. It has the advantages of decreasing pain, morbidity, and the need for second surgical site, but connective tissue graft was superior to it in all clinical parameters measured.
