摘　　要：目的:在三维标准牙冠数据的基础上,实现调的模拟过程。方法:对牙冠的咬合设计进行一定简化和假定,以势能场函数来模拟调的数学表示,并得出相应的求解方程。结果:在Matlab环境下进行了实现,给出了调的实际例子。结论:用数学公式来模拟描述牙冠设计的调,有一定理论意义。Objective: Basedonthe3Dstandardtooth data, to realizethe modeling procedure oftheocclusal adjustment. Method: Simplify and presume the procedure of the occlusal adjustment on the tooth restoration, using potential energy field functions to model the mathematic expression of the occlusion-adjusting, and result to the corresponding equation. Results: Giving the practical example of the occlusal adjustment under the Matlab environment. Conclusion: There are theoretic significance by some means in using the mathematic formula to describe the occlusal adjustment procedure during the design of the tooth restoration.
