Abstract

The invention discloses a method for preparing a false tooth support through a 3D printing laser stereo-lithography technology. According to the method for preparing the false tooth support through the 3D printing laser stereo-lithography technology, the individual false tooth support most suitable for a patient is printed through the 3D printing laser stereo-lithography technology; the comfort level and the service life of the false tooth support are ensured by means of a finite element technology; the operation difficulty of a physician is lowered; the manufacturing cost is reduced; the manufacturing period is shortened. The surface of the false tooth support is processed through an anodizing and / or electrochemical deposition method so that the surface of the false tooth support can have more excellent synosteosis features and biology activity, osteoblast growth and surface calcification are facilitated, and the satisfaction of the patient is improved. The method is suitable for the field of medical devices.

Description

technical field

[0001] The invention relates to the field of medical devices, in particular to a method for manufacturing a denture bracket based on 3D printing laser stereoforming technology. Background technique

[0002] At present, dentition defect is a common disease in clinical oral cavity. Removable partial denture is one of the main methods to repair dentition defect. It has a wide range of indications and is relatively cheap. Removable partial dentures are divided into crowns and denture frames. Due to the difference in the shape of each person's jaw, the condition of the dentition defect is different, and the shape of the denture bracket is very different, so the denture bracket has always been a personalized design. The shape is more complicated, and the force is also more complicated. The doctor's experience requirements and technical requirements are relatively high. Because it is a personalized design, each denture bracket is different, and the rationality of ...

Examples

Embodiment Construction

[0031] refer to Figure 1 to Figure 8 , the present invention is a method for manufacturing a denture bracket based on 3D printing laser stereoforming technology, comprising the following steps:

[0032] a) Construct the three-dimensional model of the denture bracket through forward modeling or reverse modeling;

[0033] b) Stress analysis and fatigue analysis of the three-dimensional model of the denture bracket using finite element technology;

[0034] c) Print the denture bracket through 3D printing laser stereoforming technology;

[0035] d) Using anodic oxidation and / or electrochemical deposition methods to carry out surface treatment on the denture bracket;

[0036] e) Use scanning electron microscope and / or electron probe and / or X-ray photoelectron spectroscopy and / or laser confocal microscope and / or goniometer to carry out biological evaluation on the denture frame;

[0037] f) Comparative analysis of the electrochemical behavior of localized corrosion on the surfac...
