Current trends in clinical dental implant therapy include modification of titanium surfaces for the purpose of improving osseointegration by different additive (bioactive coatings) and subtractive processes (acid etching, grit-blasting). The aim of this study was to evaluate and compare the behaviour of hydroxyapatite and the newly developed bioactive glass coated implants (62 implants) in osseous tissue following implantation in 31 patients.
Bioactive glass and hydroxyapatite was suitably coated on titanium alloy. Hydroxyapatite coating was applied on the implant surface by air microplasma spray technique and bioactive glass coating was applied by vitreous enamelling technique. The outcome was assessed up to 12 months after prosthetic loading using different clinical and radiological parameters.
Hydroxyapatite and bioactive glass coating materials were non-toxic and biocompatible. Overall results showed that bioactive glass coated implants were as equally successful as hydroxyapatite in achieving osseointegration and supporting final restorations.
The newly developed bioactive glass is a good alternative coating material for dental implants.
目前临床牙科植入物治疗的趋势包括改变钛表面，通过不同的添加剂（生物活性涂层）和减法工艺（酸蚀、喷砂）来提高骨整合。本研究的目的是评估和比较羟基磷灰石和新开发的生物活性玻璃涂层植入物（62 个植入物）在 31 名患者植入骨组织中的行为。
生物活性玻璃和羟基磷灰石适当地涂覆在钛合金上。羟基磷灰石涂层通过空气微等离子喷涂技术施加在植入物表面，生物活性玻璃涂层通过玻璃搪瓷技术施加。在修复体负载后 12 个月内，使用不同的临床和影像学参数对结果进行评估。
羟基磷灰石和生物活性玻璃涂层材料是无毒和生物相容的。总体结果表明，生物活性玻璃涂层植入物在实现骨整合和支持最终修复方面与羟基磷灰石同样成功。
新开发的生物活性玻璃是一种用于牙科植入物的良好替代涂层材料。
