摘要
目的:初步对微创技术在口腔种植中的应用进行临床探讨。方法:2008年至2009年间,共对16例牙缺失患者行微创牙种植术,其中男性6例,女性10例。采用曲面断层全景片和CT计算机导航技术进行术前检查,运用或不运用手术导板,采用不翻开粘骨膜瓣或改良的不翻瓣方法植入种植体。通过测定术后当日、1个月、3个月、6个月、12个月和18个月的x线牙槽骨改变进行临床评价,并对种植体的稳定性进行共振频率分析(RFA),记录分析种植体稳定性数值(ISQ)。结果:共植入种植体57枚,术后8~16周进行永久修复,全部修复获得令人满意的功能和美观效果。随访时间为18个月,种植体存留率为100%,X线观察牙槽骨无明显吸收状况。种植体植入当日ISQ测定为一例患者6枚种植体44-46,其余种植体ISQ大于60,所有种植体冠修复后ISQ值均大于60,经方差分析在各时间段的ISQ值无显著差异。结论:微创牙种植技术操作简单,手术时间短,手术创伤小,在严格地掌握适应症,术前结合CT制定治疗计划,术中仔细操作下,可以获得满意的临床结果。
Objective: To explore the clinical results of dental implants using minimal invasion surgical technique. Methods : The study population consisted of 16 patients (6 males and 10 females) who were referred implant placement using minimal invasion surgical technique during 2008 - 2009. Computer tomography had been taken before surgery, implants were placed using flapless surgical technique. The clinical parameters were evaluated by checking crestal bone changes of X - ray. Implant stability quotient (ISQ) values were measured at placement surgery and 1, 3, 6, 12, 18 months after installation. Results: 57 implants were placed, final prosthesis were finished 8 -16 weeks after surgery, all implants were in good condition. The survival rate after 18 months' following -up was 100% , no significant marginal bone loss of peri - implant was observed. The ISQ at placement surgery were all more than 60 except fnr 6 implants of one patient ( ISQ 44 - 46), the final ISQ after prosthetics all exceeded 60, and there was no significantly difference. Conclusion: The method of dental flapless surgery is simple, the operation time can be shorten greatly and the invasive was mini- mized, a satisfactory clinical resuh can be arrived contributing to careful patient selection,treatment plan design and operation.
