Model-free digitization adaptation method used for oral cavity restoration body

Abstract

The invention discloses a model-free digitization adaptation method used for an oral cavity restoration body. The method comprises the following steps of (1) through nuclear magnetic resonance in a medical image, carrying out image scanning on an internal portion of an oral cavity of a patient, and through software, realizing a three-dimensional form entity and acquiring three-dimensional data; (2) according to the three-dimensional data acquired in the step (1), through combining a lesion condition in the internal portion of the oral cavity of the patient, using a CAD technology to carry out data analysis and three-dimensional design on the restoration body; and (3) carrying out primary processing on three-dimensional design data of the restoration body designed and completed in the step (2) through restoration body processing equipment. In the invention, through scanning a diseased area of the oral cavity of the patient, three-dimensional data of the diseased area is acquired; based on the three-dimensional data, through using the CAD technology, the restoration body is designed, and finally three-dimensional scanning is performed on a processed product; product data is acquired and is compared to original three-dimensional data of the patient; and polishing and repairing are performed in real time so as to realize digitization of detection and adaption processes.

Description

technical field [0001] The invention relates to the technical field of oral prosthetics, in particular to a modelless digital fitting method for oral prosthetics. Background technique [0002] With the development of society and the continuous improvement of people's living standards, people's pursuit of beauty is gradually increasing. More and more people are beginning to pay attention to their dental health problems. Many people have different degrees of dental diseases, such as dental caries, missing teeth, periodontal disease, and irregular teeth. The third national oral health epidemiological survey shows that the prevalence of oral diseases in my country is as high as 90%. Many studies have proved that oral diseases not only affect the physiological functions of the oral cavity, but also affect the health of the whole body to varying degrees, and even become an important cause of some systemic diseases. [0003] The continuous development of science and technology an...

Problems solved by technology

[0005] For the detection of the processed restorations, the detection methods in the general dental laboratory are relatively simple. Calipers are used to detect the size, and at the same time, the suitability is observed by trying it on the plaster dental model. is a rather complicated process

At the same time, the measurement accuracy of calipers is limited, and it is more suitable for the measurement of parts with regular shapes. However, for an oral restoration product, its shape is irregular and composed of many complex curved surfaces. The basic dimensions such as length, width, height, and depth are measured, and the measurement error is relatively large. The accuracy of the measurement is related to the instrument itself and the operator.

On the other hand, this measurement method cannot analyze the accuracy of each part of the formed product

The deformation of the product cannot be directly measured, there is no strict quantitative index, and it cannot be visualized
