The prosthesis loading force is an important factor for dental implant survival. Even if adequate osseointegration of the dental implant has been achieved, if the occlusal forces are not correctly distributed, lateral torque can be generated causing high stress on surrounding tissues. The stress value of implant prostheses could be different whether the direction of load is vertical or oblique, affected by the shape of the occlusal surface. When an implant-supported prosthesis is designed with a dental computer-aided design software program, the average vectors from each occlusal contact point can be visualized. If the visualized vector generates lateral torque, the occlusal surface design can be modified before finalizing the design. The described technique uses automated vector analysis to enable visualization of the occlusal vector to improve prosthesis design, optimizing occlusal forces.
种植体负载力是影响种植体存活的重要因素。即使种植体与骨组织达到了理想的骨整合，在咬合力量没有正确分布的情况下，也可能会产生侧向扭力，从而对周围组织造成高应力。种植体修复体的应力值会因受力方向是垂直还是倾斜而有所不同，这受到咬合面形状的影响。当使用口腔计算机辅助设计软件程序设计种植体支持的修复体时，可以直观显示每个咬合接触点的平均力向量。如果可视化向量产生侧向扭力，可以在最终确定设计之前修改咬合面设计。所描述的技术使用自动化向量分析来直观显示咬合向量，以改进修复体设计，优化咬合力量。
