Introduction: The aim of this retrospective study was to analyze the radiographic peri-implant bone loss of bone level implants and tissue level implants with a convergent neck in screw-retained single crowns and in screw-retained fixed partial prostheses, after two years of functional loading. Materials and methods: The sample was divided into two groups according to their type: Group I: supracrestal implants with convergent transmucosal neck; Group II: crestal implants. In each group we distinguish two subgroups according to the type of prosthetic restoration: single crowns and a three-piece fixed partial prosthesis on two implants. To quantify bone loss, parallelized periapical radiographs were analyzed at the time of implant placement and after two years of functional load. Results: A total of 120 implants were placed in 53 patients. After statistical analysis it was observed that for each type of implant bone loss was 0.97 ± 0.91 mm for bone level and 0.31 ± 0.48 mm for tissue level. No significant differences were found regarding the type of prosthesis and the location (maxilla or mandible) of the implants. Conclusions: Tissue level implants with a convergent transepithelial neck exhibit less peri-implant bone loss than bone level implants regardless of the type of prosthesis.

组织水平的具有收敛颈的牙科植入物的围植入行为

简介:这项回顾性研究的目的是分析在使用两年的功能性螺钉固定的单个牙冠和螺钉固定的固定部分假体中会聚颈部的骨水平植入物和组织水平植入物的射线照相植入物周围骨丢失情况加载中。材料和方法:根据类型将样品分为两组:第一组:具有会聚的跨粘膜颈部的上骨上植入物;第二组:晶状体植入物。在每组中,我们根据修复体的类型将其分为两个亚组:单个牙冠和两个植入物上的三件式固定局部修复体。为了量化骨丢失,在植入种植体时和两年的功能负荷后分析了平行的根尖周X光片。结果:53例患者总共植入了120个植入物。经过统计分析,发现每种植入物的骨水平骨损失为0.97±0.91 mm,组织水平骨损失为0.31±0.48 mm。关于假体的类型和植入物的位置(上颌骨或下颌骨),没有发现显着差异。结论:无论假体类型如何,具有会聚的上皮颈的组织水平植入物的种植体周围骨丢失均少于骨水平植入物。
