Problems solved by technology

However, the problem of powder metallurgy is the shrinkage of the metal after forming and sintering, which will inevitably reduce the forming accuracy of the removable partial denture bracket, and the production process has many procedures, and the production cost is even higher than that of the casting process.

Embodiment 1

[0039] Embodiment 1 The method for manufacturing an oral prosthesis bracket manufactured by metal additives according to the present invention comprises the following steps:

[0040] 1) Obtain the 3D model data of the patient's oral cavity and upper jaw: take the mold from the patient's mouth and make a plaster cast of the oral cavity, and obtain the 3D point cloud data of the plaster cast by scanning the plaster cast of the oral cavity with a scanning device, or directly scan the patient's mouth with a scanning device to obtain directly The 3D point cloud data of the patient's oral cavity, and the 3D point cloud data is exported to the triangular mesh model through the scanning software;

[0041] 2) Select the maxillary surface of the oral prosthesis bracket on the model: import the triangular mesh data in step 1) into the reverse engineering software Geomagic, and select the tissue surface base of the oral prosthetic bracket on the triangular mesh model surface, and generate...

Embodiment 2

[0048] Example 2 The dental prosthesis bracket made according to the manufacturing method described in Example 1 includes a body made of metal material, and the body includes a sleeve part 1 and a support part 2 with a mesh structure, so The said fitting part 1 is arranged on the edge of one side of the said supporting part 2, the said mesh structure 21 is located on the other side of said supporting part 2, and said fitting part 1 and said The support part 2 is integrally formed; the support part 2 fully fits the patient's defective oral and maxillofacial region and provides the supporting force required to resist the physiological movement of the oral and maxillofacial region, and the fitting part 1 is set on the patient's partial dentition, Moreover, the said fitting part 1 has a shape for providing the supporting force required for tooth movement.

[0049] The metal material is stainless steel, pure titanium, titanium alloy, cobalt-chromium alloy.

Abstract

The invention discloses a dental prosthesis stent made of metal additives and a method for manufacturing the dental prosthesis stent made of the metal additives. The method includes: acquiring data of a three-dimensional maxillary model of a patient, selecting a maxillofacial surface of the dental prosthesis stent on the model, reconstructing the maxillofacial surface, stretching the maxillofacial surface until formation of an initial stent model, and repairing the initial stent model to meet design requirements for forming a stent CAD (computer aided design) model available for printing and manufacturing; adopting a selective laser melting 3D (three-dimensional) printer for printing and manufacturing to obtain a stent model, and subjecting the stent model to thermal treatment and surface treatment. The dental prosthesis stent comprises a body made of a metal material, and the body comprises a nesting portion and a supporting portion with a mesh structure. The dental prosthesis stent made of the metal additives and the method for manufacturing the dental prosthesis stent made of the metal additives have the advantages that the structure meeting clinical requirements is made by means of 3D printing technology, high precision, high surface quality and short manufacturing period are realized, and the clinical requirements are met better.

Description

technical field [0001] The invention relates to a method for manufacturing an oral prosthesis bracket manufactured by metal additives and the prosthesis bracket. Background technique [0002] Jawbone and facial defects are a kind of disease in stomatology that seriously endangers human health. It not only causes obstacles to the physiological functions of patients such as chewing, swallowing, and language, but also causes severe facial deformities in patients, causing serious psychological problems in patients. Obstacles, and even some patients lose confidence in life, leading to personal and family tragedies. The reconstruction of the defected maxilla is generally divided into two methods: surgical restoration and oral prosthesis. In recent years, although various surgical reconstruction methods have made great progress, due to the special anatomical shape and tissue structure of the maxillofacial organs, many defects are still difficult to use autologous tissue for surgic...
