Intelligent step-by-step method for tooth movement based on initial and final positions

Abstract

The invention discloses a method for intelligently moving teeth step by step according to the initial position and the final position, based on a computer, including: step S1, input parameters; step S2, for each tooth, set the position from the initial position to the final position At least one stage; step S3, for each stage of each tooth, obtain the position and posture of each step of the tooth in the transformation process; step S4, use the tooth number as the row number, and take the number of steps as the vertical number, set The position and posture of each step of the teeth are filled into the table items to obtain a step-by-step table of teeth; step S5, starting from the first column, calculate whether each tooth collides with adjacent teeth, if there is a collision, cancel the collision, and execute step S6 , if there is no collision, execute step S6; step S6, repeat step S5 for the next column until the last column of the tooth step table. The invention simplifies the operation of technicians and improves the step-by-step efficiency.

Description

technical field

[0001] The invention relates to the technical field of orthodontics, in particular to an intelligent step-by-step method for tooth movement. Background technique

[0002] In recent years, digital oral technology has developed rapidly, and invisible orthodontics have gradually become popular. According to the initial position of the teeth and the final position of the design, appropriate steps are inserted in the middle, so that the orthodontic treatment can be carried out in an orderly, reasonable and step-by-step manner. The step-by-step technique that has been widely used at present, the main defect is that the technician needs to manually insert the intermediate steps, and at the same time, the technician needs to arrange the movement sequence of the teeth reasonably according to the doctor's requirements, and in order to avoid collisions between the teeth during the movement, the initial position Between the final bit, several intermediate bits are inser...

Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing.

[0029] see figure 1 , according to the initial position and the final position of the present invention, the tooth movement is intelligently divided into steps, based on a computer, comprising the following steps:

[0030] Step S1, input the parameters of intelligent stepping into the computer: the initial position, the final position, the space moving step, and the maximum slice value. in,

[0031] The initial position refers to the orthogonal coordinate system composed of the position of each tooth after the digital segmentation of the original dental model, and the mesio-distal direction, lip-lingual direction, and depression and elongation direction of the teeth.

[0032] The final position refers to the situation where the initial position coordinate system exists, keep the relative position of the coordinate system and the teeth unchanged, arrange the teeth to the s...
