Abstract

PURPOSE

This study aimed to assess the use of bone augmentation materials in Finland from 1994 to 2012 by assessing removal rates of implants placed in combination with autologous bone, xenogeneic grafts, and synthetic alloplastic materials.

MATERIALS AND METHODS

The National Institute for Health and Welfare in Finland granted permission to access raw data of the Finnish Dental Implant Register for implant augmentation materials and removal rates of implants placed in augmented sites from April 1994 to April 2012.

RESULTS

A total of 198,538 implants were placed in Finland between 1994 and 2012 in 110,543 operations. A total of 3318 (1.7%) of the placed implants were removed during the observation period. Augmentations were performed on 20,812 (18.8%) operations during 1994-2012. The removal rates of implants placed at sites augmented with autologous bone were 2.31%, xenogeneic materials 0.91%, and synthetic alloplastic materials 2.80%. The removal rate was 1.87% when no augmentation material was used.

CONCLUSIONS

The placement of dental implants in conjunction with bone augmentation materials is predictable with a low complication rate.

摘要

目的

本研究旨在通过评估与自体骨、异种移植物和合成异质材料联合植入的种植体的移除率，来评估1994年至2012年期间芬兰骨增量材料的使用情况。

材料与方法

芬兰国家健康与福利研究所批准获取芬兰牙种植体登记处的原始数据，这些数据涉及种植体增量材料以及1994年4月至2012年4月期间在增量部位植入的种植体的移除率。

结果

1994年至2012年期间，芬兰共进行了110543例手术，植入了198538颗种植体。在观察期内，共移除了3318颗（1.7%）植入的种植体。1994年至2012年期间，20812例（18.8%）手术进行了增量操作。在使用自体骨增量的部位植入的种植体的移除率为2.31%，异种材料为0.91%，合成异质材料为2.80%。未使用增量材料时，移除率为1.87%。
