Problems solved by technology

[0006] However, the hardness of the zirconia material is too hard to be worn easily. If there is no good polishing, it will wear the deciduous teeth and permanent teeth. In the case of asymmetric restoration, the excessively worn deciduous teeth or permanent teeth will damage the deciduous teeth Alignment and occlusal function as well as oral and maxillofacial growth and development have profound effects

Abstract

The invention belongs to the field of medical instruments and relates to a use method of resin, a use method of polyether-ether-ketone and a manufacturing method of a deciduous tooth preformed crown. The resin is used as the material of the deciduous tooth preformed crown; the polyether-ether-ketone is used as a material of the deciduous tooth preformed crown. The manufacturing method of the deciduous tooth preformed crown comprises the following steps of: S1, manufacturing a digital model of the deciduous tooth preformed crown; S2, according to the digital model, performing digital cutting on an initial material to obtain a semi-finished product of the deciduous tooth preformed crown; and S3, polishing the surface of the semi-finished product of the deciduous tooth preformed crown to obtain a finished product of the deciduous tooth preformed crown. According to the manufacturing method of the deciduous tooth preformed crown of the invention, the3D digital model of the deciduous tooth preformed crown isestablished; and 3D printing is performed to obtain the deciduous tooth preformed crown according to the parameters of the 3D digital model. According to the use method of the resin, the use method of the polyether-ether-ketone and the manufacturing method of the deciduous tooth preformed crown of the invention, deciduous teeth, the occlusion function and the growth and development of an oral-maxillofacial region are ensured.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a method for using resin and polyetheretherketone and a method for making preformed crowns of deciduous teeth. Background technique [0002] The development of children's deciduous teeth affects children's chewing, pronunciation, aesthetics, and oral and jaw functions. It also affects the growth and development of the oral and maxillofacial region and general health. Therefore, maintaining the health and integrity of deciduous teeth is very important for children's oral health and general health. The caries rate of deciduous teeth of children in my country is high. The fourth national epidemiological survey shows that the caries rate of 5-year-old children is as high as 71.9%, and only less than 20% have received treatment. [0003] Prefabricated crowns for deciduous teeth are a treatment method suitable for the restoration of severe dental tissue damage in children. The crowns pr...
