摘要
背景:大量研究表明,牙周组织引导再生技术的使用显著提高了即刻种植技术的成功率,甚至在临床上与延期种植成功率无明显差别。目的:比较种植体即刻种植和延期种植修复前牙的临床效果。方法:选择前牙种植体修复患者100例,共160颗患牙,按照随机配对原则分为试验组和对照组,试验组微创拔牙后将种植体即刻植入拔牙窝内,配合运用牙周组织引导再生技术完成种植体植入过程;对照组微创拔牙3个月后,将种植体植入拔牙窝内,配合运用牙周组织引导再生技术进行失牙区义齿延期种植修复过程,两组均在种植体植入后3个月进行上部冠修复。对比两组种植修复治疗后的美学效果、牙周袋深度及种植体成功率。结果与结论:试验组修复完成后1,3,6,12个月的牙龈美学评分优于对照组(P<0.05),修复1,3,6,12个月的牙周袋深度小于对照组(P<0.05);两组修复12个月后种植体成功率比较差异无显著性意义(P>0.05)。表明种植体即刻种植修复在美学效果、治疗周期、牙周组织健康程度方面均优于延期种植修复,但修复成功率与延期种植修复无明显差异。
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）. 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.
