Embodiment Construction

[0014] The specific embodiments of the present invention will be further described below with reference to the examples.

[0015] A method for additive manufacturing of a personalized dental crown provided in this embodiment includes the following steps:

[0016] a. Complete the acquisition of personalized crown data according to the needs of the patient. Due to the different shape of the crown required by each patient, it has different data. The data can be obtained from the patient's description or provided by the patient;

[0017] b. Carry out three-dimensional modeling according to the data in step a;

[0018] c. Optimizing the design of the occlusal contact points of the three-dimensional model of the personalized dental crown in step b; as an option, finite element technology can be used to optimize the three-dimensional model of the personalized dental crown. Therefore, it can be highly matched to the patient's oral cavity, so that the patient can restore the chewing a...

Abstract

The present invention relates to the technical field of additive manufacturing of dental crowns, and in particular to a method for additive manufacturing of personalized dental crowns, comprising the following steps: a. Complete the acquisition of personalized dental crown data according to the needs of patients; b. According to step a Perform three-dimensional modeling on the data in step b; c, optimize the occlusal contact point of the personalized dental crown three-dimensional model in step b; d, import the optimized three-dimensional model data in step c into related equipment, and personalize the dental crown Do additive manufacturing. The rapid printing of dental crowns can be completed through additive manufacturing technology, especially the use of light-curing printers can shorten the printing time of dental crowns. At the same time, this method can meet the individual needs of dental crowns and avoid the discomfort caused by mass production of dental crowns. Thereby different patients are suitable for different dental crowns.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing of dental crowns, in particular to a method for additive manufacturing of personalized dental crowns. Background technique [0002] Additive manufacturing technology is a technology that uses a method of gradually accumulating materials to manufacture objects. Compared with the traditional material removal-cutting processing technology, it is a bottom-up manufacturing method. In the past two decades, additive manufacturing technology has achieved rapid development. Different names such as rapid prototyping, 3D printing, and entity free manufacturing express the characteristics of this technology from different aspects. Additive manufacturing technology refers to a scientific and technological system that directly manufactures parts based on the principle of discrete-accumulation and is driven by three-dimensional data of parts. Based on different classification principles and ways ...
