[0018] A method for generating an occlusal curve of a mandibular tooth model, comprising the steps of:

[0019] A method for generating an occlusal curve of a mandibular tooth model, comprising the steps of:

[0020] a. Set each parameter of the initial curve as an adjustable parameter; wherein, the initial curve is an arbitrary curve, or a standard curve suitable for most people;

[0021] b. If figure 1 , 2 As shown, the Euclidean distance from the two key points of the buccal incisal end of each tooth to the initial curve is used as the loss function;

[0022] c. Continuously adjust the parameters of the curve according to the gradient descent method to minimize the output value of the loss function (that is, the distance from the key point to the curve), and generate a final occlusal curve that conforms to the arrangement of the teeth.

[0023] In one of the embodiments, specifically, in step b, the distal and proximal points of the buccal incisal edge of each tooth are ...

Abstract

The invention discloses a generation method of an occlusion curve of a jaw tooth model. The generation method comprises the steps as follows: a, setting each parameter of an initial curve as an adjustable parameter; b, taking the Euclidean distance between two key points of cutting end of the cheek side of each tooth and the curve as a loss function; and c, continuously adjusting each parameter of the curve according to a gradient descent method to minimize an output value of the loss function to generate a final occlusion curve conforming to the tooth arrangement condition. The final occlusion curve generated by the generation method provided by the invention has greatly improved accuracy and provides more accurate reference of tooth arrangement condition for following orthodontics.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to a method for generating an occlusal curve of a mandibular tooth model. Background technique [0002] At present, in orthodontics, in order to obtain the arrangement of the teeth, the traditional method is to judge the arrangement of the teeth through manual observation and imagining the virtual occlusal curve. This method has the problem of low accuracy. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a method for generating the occlusal curve of the mandibular tooth model. [0004] The technical scheme adopted in the present invention is: [0005] A method for generating an occlusal curve of a mandibular tooth model, comprising the steps of: [0006] a. Set each parameter of the initial curve as an adjustable parameter; wherein, the initial curve is an arbitrary curve, or a standard curve suitable for mo...
