This study evaluated the effects of axial and oblique occlusal loading on implant-supported partial dentures with different connection systems (external hexagon, internal hexagon, and Morse taper). Upon axial loading, all systems presented similar stress values. Stress values increased under oblique loading. Stress distribution changed for some of the internal connection structures. It can be concluded that oblique load increases stress on bone structures and prosthetic components. Internal connection system implants present more favorable stress distribution patterns than do external connection system implants.
本研究评估了轴向和斜向咬合负荷对具有不同连接系统（外六角形、内六角形和莫氏锥度）的种植体支持局部义齿的影响。在轴向负荷下，所有系统的应力值相似。在斜向负荷下，应力值增加。一些内部连接结构的应力分布发生了变化。可以得出结论，斜向负荷会增加骨结构和修复部件上的应力。与外部连接系统种植体相比，内部连接系统种植体具有更有利的应力分布模式。
