Embodiment Construction

[0034] In order to make the purpose, advantages and features of the present invention more clear, a method for generating a virtual tooth root that can control the shape proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that: the drawings are all in a very simplified form and use inaccurate proportions, which are only used to facilitate and clearly illustrate the purpose of the embodiment of the present invention; secondly, the structures shown in the drawings are often actual structures part; again, each drawing needs to display different emphasis points, and sometimes adopts different scales.

[0035] The present invention provides a virtual tooth root generation method capable of controlling the shape, which includes the following implementation steps:

Abstract

The invention relates to a virtual tooth root generation method capable of controlling the shape. The method mainly comprises the following steps of: 1, establishing a three-dimensional coordinate system M1, and drawing a tooth root virtual contour in an X1Y1 plane of the three-dimensional coordinate system M1, 2, determining an actual boundary line L of any tooth T, 3, selecting any point p on the boundary line L, and determining a plane D, 4, establishing a three-dimensional coordinate system M2, 5, determining a transformation matrix A of the tooth root virtual contour from the three-dimensional coordinate system M1 to the three-dimensional coordinate system M2, and 6, obtaining a final curved surface K1, namely the required virtual tooth root, by utilizing the transformation matrix A.By means of the method, virtual tooth roots in different shapes can be generated for incisor teeth, canine teeth and molar teeth, the recognition degree of various teeth is improved, and the method can be achieved only through one algorithm.

Description

technical field [0001] The invention relates to a virtual tooth root generation method capable of controlling the shape. Background technique [0002] With the continuous improvement of living standards, people have higher and higher requirements for their own appearance. Orthodontics can not only effectively improve the appearance of patients, but also bring confidence to patients when getting along with others. Fixed brackets need to be bonded to the teeth during the treatment period, which affects the appearance; and the risk of oral infection increases, which brings pressure to the patient. Invisible aligners have an invisible effect and have the advantages of less chance of oral infection, and have been greatly developed. Before the patient wears invisible aligners, doctors and technicians need to use orthodontic software to formulate a treatment plan for the patient to obtain the final treatment effect. The orthodontic software needs to import the patient's tooth mo...
