Embodiment 1
[0026] see Figure 1-2 , the present invention provides a technical solution: a manufacturing process of a novel 3D printed movable denture bracket, comprising the following steps:
[0027] Step S1: Model inspection, check whether the model is intact, whether the accessories are complete, whether the occlusal space is sufficient, whether there is a good common seating path, etc., to ensure that the model meets the production requirements;
[0028] Step S2: Model making, clean the silicone tray with water and dry it with an air gun, adjust the plaster with a vacuum mixer, pour the plaster into the tray, wait for 30 minutes until the plaster is completely solidified, and use a plaster finisher on the bottom of the plaster model Shuhei;
[0029] Step S3: Scan the model, fix the upper and lower bites with wax, put the model into the 3shape scanning chamber, start the scanning program to scan the model;
[0030] Step S4: CAD design, CAD designers design the bracket on the oral sc...

Abstract
The invention discloses a novel manufacturing process of a 3D printing movable false tooth support frame. The process comprises the following steps of model inspection: checking whether a model is complete or not; making the model: cleaning a silica rubber tray by water, performing blowing drying by an air gun, and filling gypsum into the tray; model scanning: performing fixation by wax and performing vertical engaging, then, putting the model into a 3 shape scanning cabin, and starting the scanning procedure to perform model scanning; CAD design: performing support frame design on oral cavityscanning data by a CAD design person; 3D support frame printing: a 3D printing center person checks that the designed support frame has a reasonable layout angle and no deformation, and puts printingmaterial titanium powder or cobalt chromium powder into a printing cabin for printing; post treatment: performing sintering stress release after the printing is completed, wherein the stress releasetemperature is 830 DEG C for pure titanium, and is 1,050 DEG C for cobalt chromium alloy, and after the cooling, eliminating an oxide layer on the surface of a casting by a sand blasting machine. Themanufacturing process has the advantages that the material cost and the labor cost are reduced; the rework rate is greatly reduced, so that the movable false tooth support frame is more precise.
Description
technical field [0001] The invention relates to the technical field of 3D printing, in particular to a manufacturing process of a novel 3D printing movable denture bracket. Background technique [0002] The production process of the production process of the traditional movable denture bracket: [0003] 1. Model making, clean the silicone tray with water and dry it with an air gun, adjust the gypsum with a vacuum mixer, pour the gypsum into the tray, use a vibrator to remove the air bubbles in the tray, and wait for 30 minutes until the gypsum is completely solidified. Smooth the bottom of the plaster model with a gypsum trimmer; 2. Determine the positioning path, use the observer to design the position of the snap ring and determine the undercut area, and fill the undercut area at the snap ring position with anhydrite; Fill the plaster mold with the undercut and put it into the remodeling box, fill the agar cooked in the agar machine into the remodeling box, wait for 30 mi...
