摘要：

文题释义：
氧化锆种植体：钛合金种植体是当前牙科种植的金标准，但其灰色外观导致美学效果较差且有引发过敏反应的风险。氧化钇稳定四方相氧化锆陶瓷种植体(即氧化锆种植体)具有与天然牙齿色泽相近、力学性能优异、生物相容性好的优点，逐渐成为种植体材料的热门选择。
抗旋结构：基台和种植体连接部位的设计特点，指的是基台与种植体能否在受到旋转或侧向外力时松脱，常设计为四角、六角、八角形、栓条状等嵌套啮合抗旋或利用摩擦抗旋。单牙修复时，修复冠通常能在外力作用下旋转，所以在选择种植系统时要考虑是否具备抗旋特性。

背景：两段式粘接固位氧化锆种植体在临床应用中存在折断风险，不同抗旋结构直接影响种植体-基台连接方式的可靠性，并可能间接影响向骨组织传导的应力大小及分布。
目的：探索更适合两段式粘接固位氧化锆种植体-基台连接方式的抗旋结构。
方法：在NX 12.0制图软件中绘制6组不同抗旋结构形状(圆三角形、三花瓣形、四方形、十字键槽形、六方形、Torx形)的种植体系统及周围骨模型，以X_T格式导入ANSYS 2021软件中，向模型施加模拟口内咬合和种植体植入时的受力，通过对比种植体、基台、粘接剂和周围骨应力的大小及分布，预测种植体断裂可能性及对周围骨质的影响。
结果与结论：①垂直载荷下，仅种植体受抗旋结构形状影响，四方形、三花瓣形抗旋结构下的种植体受力最小，但三花瓣形抗旋结构下的放置朝向影响种植体受力结果。倾斜载荷下，抗旋结构为圆三角形和三花瓣形时基台受力最小，但这两种形状抗旋结构摆放朝向均会影响基台受力大小；抗旋结构为十字键槽形和六方时种植体受力最小。扭矩力载荷下，抗旋结构为六方形时种植体受力最小。在3种载荷下，不同抗旋结构下粘接剂和周围骨质受力的大小和分布均无明显差异。②结果显示，抗旋结构主要与种植体-基台连接部分受力相关，对周围骨质影响较小，对粘接固位两段式氧化锆种植体而言，六方形抗旋结构可能是一种机械上具有优势的种植体-基台连接类型。

Abstract: BACKGROUND: There is a risk of fracture in the clinical application of two-piece cement-retained zirconia implants, and different anti-rotation structures directly affect the reliability of the implant-abutment connection, and may indirectly affect the magnitude and distribution of stress conduction to bone tissue.
OBJECTIVE: To explore the anti-rotation structure that is more suitable for two-piece cement-retained zirconia implant-abutment connection.
METHODS: Six sets of implant system and surrounding bone models with different anti-rotation shapes (round triangle, three-petal shape, square shape, cross keyway shape, hexagonal shape, and Torx shape) were drawn in NX12.0 drawing software, and imported into ANSYS workbench2021 in X_T format, and the forces on simulated intraoral occlusion and implant placement were applied to them. By comparing the magnitude and distribution of stress on the implant, abutment, adhesive and surrounding bone, the fracture likelihood and the impact on the surrounding bone were predicted. 
RESULTS AND CONCLUSION: (1) Under vertical load, only the implant was affected by the shape of the anti-rotation structure. The implants with square and three-petal anti-rotation structures were subjected to the least force, but the placement direction of the three-petal anti-rotation structure affected the force results of the implant. Under oblique load, the abutment was subjected to the least force when the anti-rotation structure was a round triangle and three-petal shape, but the placement direction of these two shapes of anti-rotation structures would affect the force on the abutment; the implant was subjected to the least force when the anti-rotation structure was a cross keyway and hexagonal shape. Under torque load, the implant was subjected to the least force when the anti-rotation structure was hexagonal. Under the three loads, there was no significant difference in the magnitude and distribution of the force on the adhesive and surrounding bone under different anti-rotation structures. (2) The results showed that the anti-rotation structure was mainly related to the force on the implant-abutment connection part, and had little effect on the surrounding bone. For two-piece cement-retained zirconia implants, the hexagonal anti-rotation structure may be a mechanically advantageous implant-abutment connection type.
