| Abstract | Background: Dental implants have become very popular with success rate reaching around 98%. However, due to lack of anatomical structures, such as periodontal ligament, cementum and connective tissue, soft tissue around dental implants may be more susceptible to inflammation and breakdown. Therefore, attached keratinized mucosa (KM) will be more critical for dental implant and its prosthesis. There are different techniques used to augment keratinized mucosa. Studies have shown that free gingival graft, apically positioned flap and collagen matrix graft can be viable procedures to enhance soft tissue. However, given that all three procedures produce adequate amount of KM, no study focused on patients’ comfort level during the procedure and healing. Also, there has been no randomized controlled trial that compared all three procedures in gaining of KM. Aim: To evaluate and compare patients’ experience and effectiveness of free gingival graft (FGG), apically positioned flap (APF) with and without Mucograft around implants. The primary outcome was the level of patients’ discomfort and pain during procedures and healing time. The secondary outcome was width of keratinized mucosa gain with esthetic evaluation. Materials and Methods: Subjects with lack of KM (<2mm) around dental implants were randomly assigned to one of the three groups; APF alone, FGG or APF with Mucograft, to receive soft tissue augmentation procedure. After the procedure, subjects received surveys regarding their experience during procedure and during healing period for pain, swelling, and bleeding. Amount of pain medication used (Tylenol#3) was also reported by subjects. KM was measured at 3 month follow-up visit. Results: Data for the primary outcome was collected from 28 subjects (9 APF, 7 FGG, 12Mucograft) and 24 subjects presented for 3 month follow-up keratinized mucosa measurement (7 APF, 7 FGG, 10 Mucograft). There was no difference in level of discomfort during the procedure between three groups. Mucograft group showed highest level of pain, swelling during healing and number of pain meds between the 3 groups (P<0.05). Gain of keratinized mucosa measured at 3 months showed no statistically significant difference. Conclusion: The results of this study suggest that soft tissue augmentation utilizing Mucograft may cause more discomfort than FGG or APF during the healing period. All three procedures provide adequate amount of keratinized mucosa. iii |
