Embodiment Construction

[0049] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0050] The process of repairing the damaged tooth of the patient includes: using the bad tooth as the abutment, and preparing the abutment. Three-dimensional data, in which the three-dimensional data of the oral cavity includes the three-dimensional data of the abutment; design the corresponding three-dimensional data of the crown according to the three-dimensional data of the abutment, and process the crown; install the crown on the prepared abutment, and the restoration is completed. In layman's terms, it is to trim the broken top of the tooth into a regular shape, then install the pro...

Abstract

The invention provides a method for checking the printing accuracy of a 3D printer dental restoration model, comprising: obtaining the three-dimensional data of the reference model; designing and obtaining the three-dimensional data of the tooth crown; obtaining the printed model of the prepared tooth by 3D printing; processing and obtaining the processing model of the tooth crown; checking the processing of the tooth crown The coordination between the model and the prepared tooth reference model; check the cooperation between the crown processing model and the prepared tooth printing model; when the cooperation between the crown processing model and the prepared tooth reference model and the relationship between the crown processing model and the prepared tooth printing model When the cooperation between them meets the requirements, the 3D printer passes the precision inspection. Based on the prepared tooth reference model, the prepared tooth printing model and the crown processing model are obtained, and the 3D is verified by checking the cooperation between the crown processing model and the preparation tooth reference model and the cooperation between the crown processing model and the preparation tooth printing model The printing accuracy of the printer can only be used to print out the patient's crown when the printing accuracy of the 3D printer meets the requirements to ensure the restoration effect.

Description

technical field [0001] The invention relates to the technical field of dental restoration, in particular to a method for testing the printing accuracy of a 3D printer dental restoration model. Background technique [0002] When one of the patient's teeth is damaged and the damage is not high, the bad tooth can be used as the abutment, and a new crown can be installed on the abutment for repair. In the process of restoration, it is necessary to prepare the bad tooth first, and then install the crown on the prepared abutment tooth. The so-called tooth preparation is to trim the teeth into a regular shape so that they can be fitted with crowns. Today, crowns used in restorations are typically 3D printed. [0003] 3D printing is based on digital model files, using powdered metal or plastic and other bondable materials to construct objects through layer-by-layer printing. It can directly print 3D data to obtain physical products without traditional molds. Realize the 3D design...
