Abstract

Purpose: The purpose of this study was to evaluate the influence of the implant-abutment connection type on the bone level around dental implants in long-term observation and the survival rate for the different types of implant-abutment connections.

Materials and methods: Two groups of implants made of titanium grade 23 alloy and with sandblasted and acid-etched (SLA) surface were included in the study: (a) the internal hex implant-abutment connection group (480 SPI dental implants; Alpha-Bio Tec, Petach Tikwa, Israel, 184 patients) and (b) the internal cone implant-abutment connection group (60 C1 dental implants; MIS Implant Technologies, Shlomi, Israel, 34 patients). Certain inclusion and exclusion criteria were applied. Marginal bone loss (MBL) around the dental implants was measured in intraoral radiographs taken with parallel technique with a film holder and by bite recording index. X-rays were performed at the moment of functional loading, and at 12, 24, 36, and 60 months after loading. The digital analysis was conducted using Dental Studio 2.0 computer software.

Results: Average MBL was significantly lower in the conical connection compared with internal hex group-0.68 ± 0.59 versus 0.99 ± 0.89 mm (12 months), 0.78 ± 0.80 versus 1.12 ± 1.00 mm (24 months), 0.83 ± 0.87 versus 1.22 ± 1.03 mm (36 months), and 0.96 ± 1.02 versus 1.30 ± 1.15 mm (60 months after loading). Both groups of implants achieved a 100% survival rate.

Conclusion: The internal cone connection reduced bone resorption compared with the internal hex. Both groups of implants had a 100% survival rate.

长期观察种植体-基台连接方式对种植体周围骨的影响:内锥体与内六角。

目的:本研究的目的是评估种植体-基台连接方式对种植体周围骨水平的长期观察影响，以及不同种植体-基台连接方式对种植体周围骨水平的影响。材料与方法:采用23钛合金表面喷砂酸蚀(SLA)两组种植体进行研究:(a)内六角种植体-基台连接组(480 SPI牙种植体;Alpha-Bio Tec, Petach Tikwa, Israel, 184例患者)和(b)内锥体种植体-基台连接组(60例C1牙种植体;MIS Implant Technologies, Shlomi, Israel, 34例患者)。采用了某些纳入和排除标准。牙种植体周围的边缘骨质流失(MBL)是用平行技术和咬合记录指数在口腔内拍摄的x线片测量的。在功能负荷时刻，以及负荷后12、24、36和60个月进行x光检查。采用Dental Studio 2.0计算机软件进行数字分析。结果:与内嵌组相比，锥形连接组的平均MBL显著降低:0.68±0.59 vs 0.99±0.89 mm(12个月)，0.78±0.80 vs 1.12±1.00 mm(24个月)，0.83±0.87 vs 1.22±1.03 mm(36个月)，0.96±1.02 vs 1.30±1.15 mm(60个月)。两组移植体的存活率均达到100%。结论:内锥体连接比内六角连接减少骨吸收。两组移植体的存活率均为100%。
