背景:多年来,植入疗法已成为部分或完全无牙个体的常用治疗选择,长期成功率超过90%。随着生物材料和技术的显著进步,植入牙科现在可以在大多数患者中进行修复,以满足所有类型的需求。然而,为了满足不断增长的患者基础的需求,近年来,种植学的新趋势正在出现,重点是微创手术和财务可持续性。在某些临床情况下,连接牙齿和植入物以支持固定的部分假体(FPP)可能是可预测且可行的治疗过程。
方法:本研究选择了22例患者,这些患者的牙齿和种植体支持的假体作为最终修复。在这22名患者中,12名是男性,10名是女性。按照适当的方案放置植入物,并且如果需要移植程序,则进行它们。进行第二阶段外科手术,并遵循延迟加载方案。统计分析是使用IBMSPSS24.0,芝加哥,美国。通过KaplanMeier生存量表测量植入物和牙齿的存活。在基线时评估骨丢失(在加载时),12个月和24个月。
结果:在6个月时测量植入物的存活率,12个月,18个月和24个月。24个月时,一个植入物显示失败,因此植入物的存活率为95.4%。在12个月时,在一个植入物周围看到1mm的骨损失。在24个月时,在两个植入物和一个植入物周围分别存在1和2mm的骨损失。
结论:从这项研究的结果来看,我们可以得出结论,牙种植体支持的假体在康复病例中使用时显示出非常好的存活率。
BACKGROUND: Over the years, implant therapy has been a commonly used treatment option for individuals who are partially or totally edentulous, with a long-term success rate of over 90%. With significant advancements in biomaterials and technology, implant dentistry can now conduct prosthetic rehabilitations in the majority of patients catering to all types of needs. However, in order to meet the demands of a patient base that is always growing, new trends in implantology are emerging in recent years that are focused on minimally invasive surgery and financial sustainability. In certain clinical scenarios, connecting teeth and implants to support fixed partial prosthesis (FPPs) may be a predictable and workable course of treatment.
METHODS: 22 patients were selected for this study who had tooth and implant supported prosthesis placed as a final restoration. Out of these 22 patients; 12 were male and 10 were female patients. Implants were placed following proper protocol and if grafting procedures were required they were carried out. A second stage surgical procedure was carried out and delayed loading protocols were followed. The statistical analysis was done using the IBM SPSS 24.0, Chicago, USA. The survival of the implants and teeth were measured by the Kaplan Meier survival scale. Bone loss was assessed at baseline(upon loading), 12 months and 24 months.
RESULTS: The implant survival rate was measured at 6 months, 12 months, 18 months and 24 months. At 24 months, one implant showed failure, so the survival rate of the implants were 95.4%. Bone loss of 1 mm was seen around one implant at 12 months. Bone loss of 1 and 2 mm was present around two implants and one implant respectively at 24 months.
CONCLUSIONS: From the results of this study, we can conclude that tooth implant supported prosthesis show very good survival when used in rehabilitation cases.
