Force distribution with natural teeth depends on micromovement induced by the periodontal ligament. The location and cusp inclination of the tooth qualitatively alter the force pattern. Osseointegrated implants do not have micromovement associated with force distribution. Force distribution to the osseointegrated implant interface is completely different than with natural teeth. Alterations in tooth location and cusp inclination are suggested to limit implant overload. Force distribution in splinted natural teeth and osseointegrated prostheses are compared. The mechanism of interface force distribution and the consequences of poor interface fit are interrelated. The differential mobility of splinted natural teeth affects diagnosis and treatment. However, combining natural teeth with an osseointegrated prosthesis requires new design principles.
天然牙的力分布取决于牙周韧带引起的微动。牙齿的位置和牙尖倾斜度会定性地改变力的模式。骨结合种植体不存在与力分布相关的微动。骨结合种植体界面的力分布与天然牙完全不同。牙齿位置和牙尖倾斜度的改变被认为可以限制种植体过载。比较了联冠天然牙和骨结合修复体中的力分布。界面力分布机制与界面贴合不良的后果相互关联。联冠天然牙的差异移动性会影响诊断和治疗。然而，将天然牙与骨结合修复体相结合需要新的设计原则。
