Abstract:
BACKGROUND:Numerous studies have demonstrated that the use of periodontal tissue-guided regeneration technique significantly elevated success rate of immediate technical planting. No significant difference is detected as compared with the delayed planting success rate in the clinic. OBJECTIVE: To compare the clinical effects of immediate implant and delayed implant in the restoration of anterior teeth. METHODS:A total of 100 cases with former dental implants, who had 160 diseased teeth, were enroled in this study. They were divided into experimental and control groups according to the principle of random pairing. In the experimental group, the implant was put into the extraction sockets after minimaly invasive tooth extraction with the use of periodontal guided tissue regeneration technique. In the control group, at 3 months after minimaly invasive tooth extraction, implant was implanted in the sockets. Delayed planting repair of denture in the missing teeth area was performed with the use of periodontal guided tissue regeneration technique. Crown restoration was conducted in both groups at 3 months after implantation. Aesthetics, periodontal pocket depth and implant success rate were compared after repair in both groups. RESULTS AND CONCLUSION: Gingival esthetics score was better at 1, 3, 6 and 12 months after repair in the experimental group than in the control group (P < 0.05). Periodontal pocket depth was less at 1, 3, 6 and 12 months after repair in the experimental group than in the control group (P < 0.05). No significant difference in success rate of implants was detected at 12 months after repair between both groups (P> 0.05). Above findings confirmed that aesthetic effect, treatment cycle, and the health of periodontal tissue were better in the immediate implanting group than in the delayed implanting group. However, no significant difference in success rate was detected between immediate implanting and delayed implanting groups.
