摘要
目的:采用随机对比法研究改良不翻瓣微创种植术对后牙区单缺牙患者的治疗效果。方法:选取本院2017年6月~2018年6月收治的90例后牙区单缺牙缺失患者作为研究对象,按照随机数字法分为对照组和观察组各45例,其中对照组给予常规翻瓣种植术治疗,观察组则给予改良不翻瓣微创种植术。记录两组患者的治疗一般情况,包括手术时间、种植体成功率和并发症发生情况;比较术后1 h、24 h的疼痛程度和术后72 h的肿胀程度。随访观察术后1个月和3个月种植体边缘骨吸收程度。结果:两组患者均正常完成手术,其中观察组手术时间(10.35±1.20)min,远低于对照组的(14.09±1.86)min,差异具有统计学意义(t=11.334,P<0.001)。两组患者种植体成功率均为100%,且两组患者术中均未出现严重的并发症,组间差异无统计学比较意义(P>0.05)。观察组患者术后1 h和24 h的VAS评分均显著低于同期对照组;观察组患者术后72 h的肿胀程度评级明显优于对照组;上述差异均具有统计学意义(P<0.05)。所有患者均得到随访,其中两组患者在3个月和6个月的种植体边缘骨吸收程度的组间比较并无统计学意义(P>0.05);且组内比较差异无统计学意义(P>0.05)。结论:改良不翻瓣微创种植术能够达到与常规翻瓣种植术相当的疗效,并且能够显著缩短患者手术时间、减轻术后疼痛以及肿胀程度。
Objective:To study the effect of modified flapless minimally invasive implantation on single missing teeth in posterior region by random comparison.Methods:Ninety patients with single missing posterior teeth admitted to our hospital from June 2017 to June 2018 were selected as the research objects.According to the random number method,they were divided into control group and observation group,45 cases in each group.The control group was treated with conventional valvular implantation,while the observation group was treated with modified flapless minimally invasive implantation.The general treatment conditions of the two groups were recorded,including the operation time,implant success rate and complications.The pain degree at 1 h and 24 h after operation and the swelling degree at 72 h after operation were recorded and compared between the two groups.All patients were followed up for 1 month and 3 months after operation,and the bone absorption at the implant margin was observed and compared.Results:Both groups completed the operation normally.The operation time of the observation group was(10.35±1.20)min,which was much lower than that of the control group(14.09±1.86)min.The difference was statistically significant(t=11.334,P<0.001).The success rate of implants in both groups was 100%.There were no serious complications in both groups.There was no significant difference between the two groups(P>0.05).The VAS score of the observation group at 1 and 24 hours after operation was significantly lower than that of the control group at the same time,and the swelling grade of the observation group at 72 hours after operation was significantly better than that of the control group,the differences were statistically significant(P<0.05).There was no significant difference in bone resorption at implant margin between the two groups at 3 months and 6 months(P>0.05).Conclusion:Modified flapless minimally invasive implantation can achieve the same effect as conventional valvular implantation,and can significantly shorten the o
