Abstract

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.

摘要

简介

本回顾性研究的目的是分析在两年功能负荷后，采用螺丝固位单冠和螺丝固位固定局部义齿修复的骨水平种植体和软组织水平种植体（具有会聚颈部）的种植体周骨丧失情况。

材料和方法

根据种植体类型将样本分为两组：组 I：具有会聚穿黏膜颈部的骨上种植体；组 II：牙槽嵴顶种植体。在每组中，根据修复体类型进一步分为两个亚组：单冠和两个种植体上的三件式固定局部义齿。为了量化骨丧失，在种植体植入时和两年功能负荷后对平行根尖放射线片进行分析。

结果

共在 53 名患者中植入了 120 个种植体。经过统计学分析，观察到对于每种种植体类型，骨水平的骨丧失为 0.97±0.91mm，而软组织水平的骨丧失为 0.31±0.48mm。种植体的类型和位置（上颌或下颌）对骨丧失没有显著影响。

结论

无论修复体类型如何，具有会聚上皮下颈部的软组织水平种植体的种植体周骨丧失均少于骨水平种植体。
