目的:用全景片评估平齐对接种植系统、平台转换种植系统边缘骨吸收的差别。方法:植入平齐对接种植体(Noble Replace)54枚,小平台转换种植体(Osstem GS)14枚,斜肩式平台转换种植体(Bicon)25枚。在种植体植入当天、负载3个月后分别进行全景片检查,测量种植体边缘牙槽骨高度,计算牙槽骨丧失量。SPSS l4.0软件进行统计分析。结果:功能负载3个月后,平齐对接种植体近、远中边缘骨吸收量分别为1.88 mm±1.49 mm、1.81 mm±1.34 mm;斜肩式平台转换种植体为-0.68 mm±0.99 mm、-1.17 mm±1.37 mm;小平台转换种植体为0.53 mm±1.48 mm、0.74 mm±0.99 mm。三种种植体两两比较,P<0.05,相互之间存在显著性差异。结论:应用平台转换技术可减少种植体边缘骨吸收,不同的平台转换设计,其保存种植体周围骨质的能力明显不同。
OBJECTIVE: To evaluate the difference of edge bone resorption in planted butt planting system and platform in planting system with panorama film. Methods: There were 54 Noble Replace implants, 14 Osstem GS implants and 25 Bicon oblique implant implants. On the day of implant implantation, panoramic photography was performed after 3 months of loading. The alveolar bone height at the edge of the implant was measured to calculate the loss of alveolar bone. SPSS l4.0 software for statistical analysis. Results: After 3 months of functional loading, the proximal and distal bone resorptions were 1.88 mm ± 1.49 mm and 1.81 mm ± 1.34 mm, respectively. The orthodontic platform implants were -0.68 mm ± 0.99 mm , -1.17 mm ± 1.37 mm respectively; the small plateau implants were 0.53 mm ± 1.48 mm and 0.74 mm ± 0.99 mm. Three kinds of implants compared with each other, P <0.05, there is a significant difference between each other. Conclusion: The application of platform conversion technology can reduce the edge of the implant bone resorption, different platform conversion design, the ability to save the bone around the implant was significantly different.
