Abstract:Objective To explore the aesthetic impact of immediate implantation of anterior teeth with autogenous soft tissue grafting on the lip contour.Methods A retrospective analysis was conducted on 39 patients undergoing single tooth implant who received immediate implantation of anterior teeth at Daqing Oilfield General Hospital from July 2022 to June 2023. Based on the treatment method, they were divided into an experimental group (22 cases) and a control group (17 cases). In the control group, Bio-Gide was routinely applied after surgery, while the autologous connective tissue grafts were used for postoperative filling in the experimental group. Immediately after surgery, the implant accuracy, postoperative wound healing time and pain levels were compared between the two groups. Two weeks after the surgery, the levels of interleukin-6 (IL-6) and matrix metalloproteinase-2 (MMP-2) in gingival crevicular fluid were compared between the two groups. After 6 months of surgery, the stability of the implant, Pink Esthetic Score (PES), increment of attached gingival thickness and width and postoperative complications were compared between the two groups.Results There were no statistically significant differences between the two groups in terms of implant neck deviation, apical deviation, and angular deviation, ISQs, wound healing time, and pain levels at 72 hours and 1 week postoperatively (P > 0.05). The differences in PES scores between immediately after surgery and 3 months, 6 months, and 12 months postoperatively were higher in the experimental group compared to the control group (P < 0.05). The increment of attached gingival thickness and width at 3 and 6 months after surgery in the experimental group was higher than that in the control group (P < 0.05). The differences in IL-6 and MMP-2 levels between immediately after surgery and 2 weeks after surgery were not different between the two groups (P > 0.05). No severe complications were observed in either group postoperatively.Conclusions Autogenous soft tissue grafting enhances the postoperative pink aesthetic outcomes in implantation of anterior tooth, and promotes the restoration and maintenance of the labial soft tissue contour.
