Problems solved by technology

Existing databases related to permanent teeth are not applicable to deciduous teeth. There is no research on the physiological data of deciduous crowns at home and abroad, resulting in no basis for the development of children's oral CAD / CAM technology; Also refer to the opposing teeth and adjacent teeth to construct the crown shape of the affected tooth and restore it

Embodiment 1

[0020] like figure 1 As shown, a method for constructing a deciduous tooth crown physiological database provided by an embodiment of the present invention includes the following steps:

[0021] Step S1: At the mouth The maxillary and mandibular dentition models were taken from the healthy children of the system;

[0022] Step S2: scan the upper and lower dentition models with a three-dimensional dental model scanner, output three-dimensional dental data, and use reverse engineering software to extract single crown data according to the three-dimensional dental data;

[0023] Step S3: Measure the mesio-distal diameter, buccolingual diameter and gingival diameter of a single crown At the same time, the groove, fossa, cusp, and crest morphology were recorded, and the reference standard mean or sample value of each tooth position was used as the scale factor to perform the overall scaling with the sample centroid as the center, and the crown was normalized to obtain normalize...

Embodiment 2

[0062] like figure 2 As shown, the embodiment of the present invention provides a construction system of a deciduous tooth crown physiological database, including the following modules:

[0063] Obtain the maxillary and maxillary dentition model module 81 for use in the mouth The maxillary and mandibular dentition models were taken from the healthy children of the system;

[0064] Obtaining a single crown data module 82, using a three-dimensional dental model scanner to scan the upper and lower dentition models, outputting three-dimensional dental data, and using reverse engineering software to extract single crown data according to the three-dimensional dental data;

[0065] Normalized crown data module 83 for measuring the mesio-distal diameter, buccolingual diameter and gingival diameter of a single crown At the same time, the groove, fossa, cusp, and crest morphology were recorded, and the reference standard mean or sample value of each tooth position was used as the ...

Abstract

The invention relates to a method and a system for constructing a deciduous tooth crown physiological database. The method comprises the following steps: S1, taking an upper and lower jaw dentition model from a child with a healthy oral system; S2, extracting single dental crown data by using the three-dimensional dental model; S3, obtaining normalized dental crown data; S4, performing alignment processing on the normalized dental crown data, and constructing a deciduous tooth crown form database; S5, testing the bite force of the tested child, and constructing a deciduous dentition bite force database; S6, matching the bite force data with the dentition model to obtain the bite force contact point distribution condition of the single dental crown; and S7, constructing a digital deciduous tooth database according to the deciduous tooth crown form database, the deciduous dentition bite force database and the single dental crown bite force contact point distribution condition. According to the method provided by the invention, a database including the deciduous tooth crown form, the deciduous dentition bite force and the bite force contact point distribution is established, and big data support is provided for subsequent research and development of non-metal crowns.

Description

technical field [0001] The invention relates to the field of databases, in particular to a method and system for constructing a deciduous tooth crown physiological database. Background technique [0002] At present, CAD / CAM technology is rarely used in the field of pediatric dentistry. One of the reasons is that there are significant differences in the structure and physiological properties of deciduous and permanent teeth. The existing database of permanent teeth is not suitable for deciduous teeth, and there is no research on the physiological data of deciduous crowns at home and abroad, which leads to the development of oral CAD / CAM technology in children. Also refer to the opposite teeth and adjacent teeth to construct the crown shape of the affected tooth. [0003] Therefore, how to construct a physiological database of deciduous crowns has become an urgent problem to be solved. SUMMARY OF THE INVENTION [0004] In order to solve the above technical problems, the pr...
