Embodiment Construction

[0182] A kind of oral cavity parameterized measurement method of the present invention, its steps are as follows:

[0183] Acquisition of 100 data models:

[0184] 101 Acquisition of data model;

[0185] 1011 Acquiring the data model. First, use dental alginate impression material to obtain the corresponding models of the soft and hard tissues of the oral cavity and maxillofacial region; then, scan with a desktop scanner to obtain model data.

[0186] 1012 Alternatively, directly scan the soft and hard tissue structures of the oral cavity and maxillofacial region by an intraoral scanner to obtain model data.

[0187] 102 Second, use the camera to obtain facial photos from different angles, such as: front, 45° angle and side; from various states, such as: smiling state and non-smiling state;

[0188] 103 Third, use a camera to obtain photos of oral dentition, including upper dentition, lower dentition, left dentition, right dentition, and front dentition, and obtain photo im...

Abstract

The invention relates to the computer data processing, and in particular relates to a method for redefining a teeth model of the oral cavity by using the computer technology, thereby realizing the conversion of the oral cavity to a digital model from a physical model, and the dental care diagnostic procedure becomes convenient and efficient. The invention aims at providing an oral cavity parametrization algorithm, thereby solving a problem that the artificial measurement and computation are required in the prior art. The invention provides the oral cavity parameterization innovation, fuses multiple intelligent teeth feature recognition algorithms to mark out the teeth benchmark, and then automatically computes various results of oral cavity speciality examination by combining the definitions of various parameter, and the whole procedure does not exceed 1 minute. Compared with the traditional way, a fast and convenient way is provided, the accuracy rate is more than 97%, and the efficiency and the precision of the oral cavity speciality examination are greatly improved. The method disclosed by the invention has the advantages that the former judgement method depending on the doctor experience is broken through, the labor intensity of the orthodontic doctor is lowered, the measurement precision is improved, the medical treatment risk is lowered, and the in-treatment efficiency and experience are improved.

Description

technical field [0001] The invention relates to computer data processing, in particular to redefining the dental model of the oral cavity by using computer technology, realizing the transformation from the physical model of the oral cavity to a digital model, and making the dental medical diagnosis process convenient and efficient. Background technique [0002] Orthodontics is a branch of oral clinical medicine, which mainly studies the occurrence and development mechanism, diagnosis, analysis, prevention and treatment of dental and jaw deformities. For patients who need orthodontics, specialist examinations are required, including: temporomandibular joint, opening degree, opening type. Joint symptoms: pain, snapping, etc. Special examinations, including: dental models, X-ray film examinations, full maxillary tomograms, and cephalometric films. Head and maxillofacial imaging examinations, including: maxillofacial and dental and jaw photography, functional examination of th...
