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.
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.
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.
From the results of this study, we can conclude that tooth implant supported prosthesis show very good survival when used in rehabilitation cases.
多年来，种植体治疗已成为部分或完全无牙患者的常用治疗选择，其长期成功率超过 90%。随着生物材料和技术的显著进步，现在种植牙科可以为满足各种需求的大多数患者进行修复体修复。然而，为了满足不断增长的患者群体的需求，近年来出现了一些新的种植学趋势，这些趋势侧重于微创手术和财务可持续性。在某些临床情况下，将牙齿和种植体连接起来以支持固定局部义齿（FPP）可能是一种可预测且可行的治疗方法。
本研究共选择了 22 名接受牙和种植体支持修复体作为最终修复的患者。这 22 名患者中，男性 12 名，女性 10 名。按照适当的方案放置种植体，如果需要进行移植程序，则进行移植程序。进行了第二期手术程序，并遵循了延迟加载方案。使用美国 IBM SPSS 24.0 进行统计分析，芝加哥。使用 Kaplan Meier 生存量表测量植入物和牙齿的存活率。在基线（加载时）、12 个月和 24 个月评估骨丢失情况。
测量植入物的存活率为 6 个月、12 个月、18 个月和 24 个月。在 24 个月时，有一个种植体出现故障，因此植入物的存活率为 95.4%。在 12 个月时，有一个种植体周围出现 1 毫米的骨丢失。在 24 个月时，有两个种植体周围分别出现 1 毫米和 2 毫米的骨丢失，一个种植体周围出现 2 毫米的骨丢失。
从这项研究的结果可以得出结论，在修复病例中，牙种植体支持的修复体具有非常好的存活率。
