ObjectivesRetrospective evaluation of biological and technical complications in implant supported single teeth molar reximations performed in a private practice after functional periods. Material and Methods65 patients（34 females，age 51.7 10.6 years）with 112 implants received annual follow up examinations and participated in a maintenance program.评价种植体和上部结构的存活率（原位）和成功率（无并发症）。时间依赖性种植体周围炎率进行了计算，并确定使用多元考克斯regression.ResultsThe种植体存活率为100%的影响因素。112个冠中有3个需要更换（假体存活率=98.1%）。观察到30例技术并发症：固位丢失（16例）、陶瓷断裂（10例）和螺钉松动（4例）。术后7年随访，上部结构修复成功率为79.0%。总体而言，9.2%的患者发生种植体周围炎（探查深度5 mm，BOP，化脓，骨质流失3.5 mm）;（吸烟者：41.6%，非吸烟者：1.8%）。7年后，非吸烟者的时间依赖性种植体成功率（无种植体周围炎）为100%，吸烟者为58.6%。多因素分析显示，吸烟（危害比，19.5; P=0.008）对peri-implantitis.ConclusionsImplants骨水泥单齿牙在磨牙区的dispensations构成一个可靠的治疗私人执业。吸烟者的种植体周围炎发生率显著增加。
ObjectivesRetrospective evaluation of the biological and technical complications in implant-supported single-tooth molar restorations performed in a private practice after functional periods of 4years.Material and MethodsSixty-five patients (34 females, age 51.710.6years) with 112 implants received annual follow-up examinations and participated in a maintenance program. The survival (in situ) and success (complication-free) rates of implants and superstructures were evaluated. Time-dependent peri-implantitis rates were calculated, and the influencing factors were identified using a multiple Cox regression.ResultsThe implant survival rate was 100%. Three of 112 crowns required replacement (prosthetic survival rate=98.1%). Thirty technical complications were observed: loss of retention (16), ceramic fracture (10), and screw loosening (4). The success rate of the superstructures was 79.0% after 7years. Overall, 9.2% of the patients developed peri-implantitis (probing depth 5mm, BOP, suppuration, bone loss 3.5mm); (smokers: 41.6%, non-smokers: 1.8%). After 7years, the time-dependent implant success rate (free of peri-implantitis) was 100% for non-smokers and 58.6% for smokers. Multiple analysis showed a significant effect of smoking (hazard ratio, 19.5; P=0.008) on peri-implantitis.ConclusionsImplants with cemented single-tooth restorations in the molar region constitute a reliable treatment in private practice. Smokers have a significantly increased peri-implantitis rate.
