Problems solved by technology

Therefore, it is very difficult for the operator to realize the functional aesthetic design of the dentition for the restoration of the dentition and orthodontic diagnosis and treatment; not only the work process is long, but also the aesthetic shape of the anterior teeth cannot be designed according to the patient's personality and temperament characteristics

Embodiment Construction

[0026] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] According to the present invention, a digital production method for selecting an anterior tooth aesthetic form based on temperament classification has the following steps:

[0028] 1) According to the corresponding relationship between the crown and labial morphology of the 6 maxillary anterior teeth and the appearance and temperament, the aesthetic morphology of the maxillary anterior teeth is divided into 6 categories, namely beautiful type, dignified type, elegant type, handsome type, and fortitude type, bionic type;

[0029] 2) The most typical three-dimensional data of the anterior tooth shape in each type of the three-dimensional scanning step 1) is used as the basic template data D1;

[0030] 3) Allow patients to choose their favorite temperament type;

[0031] 4) Three-dimensional scanning of the maxillary dentition of...

Abstract

The invention relates to a digital model selection manufacturing method for anterior teeth aesthetics forms based on gas classification, which comprises the following steps: 1) dividing the anterior teeth aesthetics forms into six classes according to a corresponding relationship between dental crown lip surface forms and appearance gas of six teeth of maxillary anterior teeth; 2) performing three-dimensional scanning on each type of parting to serve as basic template data D1; 3) enabling the patient to select a favorite gas quality type by himself / herself; 4) performing three-dimensional scanning on the maxillary dentition of the current patient to obtain data D2; 5) taking the invariable part as a common area, firstly zooming the D1 to be similar to the D2 in size by using an integral zooming algorithm, and then registering the D1 to the D2 by using a common area registration algorithm; and 6) directly replacing the data of the corresponding area in the data D2 with the anterior teeth data in the data D1, and using a mouse to interactively adjust the detail form to obtain a digital prediction model of the individual anterior teeth aesthetic form. According to the personality characteristics of the patient, the anterior teeth aesthetic form is designed, and the aesthetic design level of the operator is rapidly improved.

Description

technical field [0001] The invention relates to a type selection of anterior teeth aesthetic shape, in particular to a type selection digital production method of anterior teeth aesthetic shape based on temperament classification. Background technique [0002] The normal tooth database currently only has the basic form, which is mainly used as the basic template for manual interactive CAD design, but for the aesthetic form, because the degree of personalization is stronger, there is no ready-made database, especially for Chinese people. The standard data of the aesthetic shape of the tooth dentition not only requires a single tooth, but also the arrangement relationship between the teeth, that is, the dentition. Therefore, it is very difficult for the operator to design the functional aesthetics of the dental dentition for dental dentition restoration and orthodontic diagnosis and treatment; not only the workflow is long, but also the aesthetic shape of the anterior teeth ca...
