Manufacture method and wearing method of digital space retainer

Abstract

The invention discloses a manufacture method of a digital space retainer and relates to the technical field of pediatric dentistry. The manufacture method comprises the following steps: S1, scanning the oral cavity of a patient by using an intraoral scanner to acquire digital models of the maxilla and the mandible of the patient and acquire the occlusion relationship; S2, designing a digital modelof a digital space retainer by combining designing software based on the acquired digital models; and S3, manufacturing the space retainer by applying a PEEK/PEKK material and combining the digital model of the digital space retainer. According to the method, the digital model is acquired by scanning the oral cavity of a patient by adopting the digital scanning technology, intraoral impression manufacture is not needed, and the situation of discomfort, even nausea and vomiting generated when an impression is manufacture for a patient can be avoided; and the digital space retainer has a largeappearance improvement, excellent biocompatibility, half radiopacity of ray and plaque adhesion prevention by adopting the specific high-molecular material PEEK/PEKK.

Description

technical field [0001] The invention relates to the technical field of children's stomatology, in particular to a manufacturing method of a digital space maintainer and a wearing method thereof. Background technique [0002] A space maintainer refers to a device made to maintain the space and maintain a normal physiological space after a child's teeth are lost prematurely. It can prevent the adjacent teeth from tilting to the lost part and the opposing teeth from elongating. The space maintainer can maintain the mesio-distal and vertical gaps of prematurely lost teeth in the dentition, and maintain the normal eruption of inherited permanent teeth. [0003] The traditional space maintainer has the following disadvantages in production: [0004] ①The production of traditional space maintainers requires intraoral impressions, and most children will feel discomfort or even nausea and vomiting; [0005] ② There are large errors in the manufacturing process of traditional space ...

AI Technical Summary

Problems solved by technology

[0004]①The production of traditional space maintainer needs to make an impression in the mouth, and most children will feel discomfort or even nausea and vomiting;

[0005]② There are large errors in the manufacturing process of traditional space maintainers. Take out the ring from the mouth and manually reset it into the impression, the position is difficult to be completely accurate, the cast plaster model may also cause the shift of the ring, and there are also a series of errors in the manufacturing process of the space maintainer, which leads to the inability of the space maintainer Fully up to precise standards, adjustments or even redoing may be required;

[0006]③The manufacturing and wearing process of the traditional space maintainer is cumbersome, the number of follow-up visits is high, and the chairside operation time is long;

[0007] ④Because the traditional space maintainer is made by hand, it is usually made of metal materials, which has the problem of not being beautiful enough. There may be some problems after wearing it, such as metal allergy, the dissolution of the glass ionomer binder causes the gap dental caries
