BACKGROUND:The stability of the implant-abutment interface is an important factor that influences load distribution on the marginal bone. OBJECTIVE:In this study, three dental implants with the same connection were subjected to different dynamic loading cycles. The fracture strengths and the horizontal compatibility of implants were assessed. METHODS:Eighty four implant specimens were embedded in a polyacetal cylinder as simulated bone loss of 3 mm from the implant platform. Three of the implants were used to determine the endurance limit. The other specimens were subdivided into four subgroups (n = 6): three for dynamic + static loading, and one for static loading (control group). The tests were performed by applying a compression load. The dynamic loading experiments included three different cycles with endurance upper limit loads at a frequency of 10 Hz. RESULTS:The differences between the fracture strength values of the implant brands were found to be statistically significant. However, there were no meaningful differences between the fracture strength values of implants of the same brand. The specimens of the DTI implant system had the lowest strength (647.9 ± 41.5 N) and the SEM analysis indicated that the Implantium implant system had the shortest horizontal gaps. CONCLUSIONS:There was a negative correlation between the fracture strengths and size of the microgaps. The importance of these in vitro results needs to be validated by clinical trials because the loads in the mouth can be applied from various angles.

具有锥形种植体-基台连接的牙科生物材料系统的动态和静态负载性能

背景：种植体-基台界面的稳定性是影响边缘骨负荷分布的重要因素。目的：在本研究中，三个具有相同连接的牙种植体经受不同的动态加载循环。评估了植入物的断裂强度和水平兼容性。方法：将 84 个种植体标本嵌入聚缩醛圆柱体中，作为距种植体平台 3 mm 的模拟骨丢失。其中三个植入物用于确定耐力极限。其他试样被细分为四个亚组（n = 6）：三个用于动态+静态加载，一个用于静态加载（对照组）。通过施加压缩载荷进行测试。动态加载实验包括三个不同的循环，频率为 10 Hz，具有耐久性上限载荷。结果：发现植入物品牌的断裂强度值之间的差异具有统计学意义。然而，同一品牌植入物的断裂强度值之间没有有意义的差异。DTI 种植体系统的样品强度最低 (647.9 ± 41.5 N)，SEM 分析表明 Implantium 种植体系统的水平间隙最短。结论：断裂强度与微间隙大小呈负相关。这些体外结果的重要性需要通过临床试验来验证，因为口腔中的负荷可以从不同角度施加。发现植入物品牌的断裂强度值之间的差异具有统计学意义。然而，同一品牌植入物的断裂强度值之间没有有意义的差异。DTI 种植体系统的样品强度最低 (647.9 ± 41.5 N)，SEM 分析表明 Implantium 种植体系统的水平间隙最短。结论：断裂强度与微间隙大小呈负相关。这些体外结果的重要性需要通过临床试验来验证，因为口腔中的负载可以从多个角度施加。发现植入物品牌的断裂强度值之间的差异具有统计学意义。然而，同一品牌植入物的断裂强度值之间没有有意义的差异。DTI 种植体系统的样品强度最低 (647.9 ± 41.5 N)，SEM 分析表明 Implantium 种植体系统的水平间隙最短。结论：断裂强度与微间隙大小呈负相关。这些体外结果的重要性需要通过临床试验来验证，因为口腔中的负荷可以从不同角度施加。DTI 种植体系统的样品强度最低 (647.9 ± 41.5 N)，SEM 分析表明 Implantium 种植体系统的水平间隙最短。结论：断裂强度与微间隙大小呈负相关。这些体外结果的重要性需要通过临床试验来验证，因为口腔中的负载可以从多个角度施加。DTI 种植体系统的样品强度最低 (647.9 ± 41.5 N)，SEM 分析表明 Implantium 种植体系统的水平间隙最短。结论：断裂强度与微间隙大小呈负相关。这些体外结果的重要性需要通过临床试验来验证，因为口腔中的负荷可以从不同角度施加。
