Embodiment Construction

[0017] Such as figure 1 as shown, figure 1 It is a schematic flow chart of the 3D printing method of the metal dental crown of the present invention. The 3D printing method comprises the following steps:

[0018] Step 101: Set STL format data.

[0019] It should be understood that STL is a specific 3D printing data format, and the three-dimensional data of the part to be printed can be converted into the STL format.

[0020] Step 102: Optimizing the placement angle of the dental crown.

[0021] It should be understood that since the inner surface of the fixed bridge of the crown will be in direct contact with the patient’s abutment teeth, it is an important molding surface, and in order to ensure the suitability of the crown edge and the interior of the crown, grinding has to be carried out in the subsequent processing, so in order to To ensure the molding quality of the inner surface, that is, to make the inner surface convenient for grinding, it is necessary to optimize ...

Abstract

The invention discloses a 3D printing method of a metal dental crown. The method comprises the steps that a, a layer of metal printing powder is laid on a printing platform; b, laser with first reserved energy value is emitted to carry out selective melting on the metal printing powder on the printing platform, and a supporting structure is formed; c, laser with second reversed energy value is emitted to carry out selective melting on the metal printing powder on the printing platform, and a metal dental crown solid layer is formed; d, laser with third reserved energy value is emitted to carryout multiple of outline crispening treatment on the metal dental crown solid layer; e, the other layer of metal printing powder is laid on the basis of the previous layer of metal printing powder, and the step b is continuously executed. Through the above manner, when the metal dental crown is printed, each metal dental crown layer is subject to crispening treatment, the inner surface and the outer surface of the metal dental crown layer are smooth, the metal dental crown cannot wear tooth flesh, and the user experience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing method of a metal dental crown. Background technique [0002] In dentistry, a crown refers to the part of the tooth exposed to the gums in a broad sense. The dental crowns referred to in the market today are mostly "artificial dental crowns" (or braces) in the narrow sense. Artificial dental crowns are mainly used to repair or restore teeth. When tooth decay or lesions or various injuries are difficult to achieve restoration through simple fillings, for health considerations and to achieve the purpose of tooth plastic beauty, at this time, under the advice of a dentist, it can be repaired through dental crowns . [0003] At present, many manufacturers on the market can automatically generate dental crowns. However, the inner and outer surfaces of the dental crowns generated on the market are rough and have dross, which is easy to wear the gum, which greatly r...
