Embodiment 1
[0040] Such as Figures 1 to 3As shown, this embodiment provides an orthodontic bonding base, including a plate body 1, the plate body 1 is crescent-shaped, the inner surface 3 of the plate body 1 is a concave curved surface, and a tapered retention hole 2 is provided. The retention hole 2 is a counterbore, the outer side 4 of the plate body 1 is a convex curved surface, and the inner side 3 is also called the bonding surface, which is used for bonding with the outer side of the posterior teeth. The hole of the tapered retention hole 2 The bottom faces the plate body, and the opening of the tapered retention hole 2 faces the tooth surface of the posterior teeth. The diameter of the bottom of the tapered retention hole 2 is smaller than the diameter of the opening.
[0041] Further, the thickness of the plate body 1 is 0.9 mm.
[0042] Further, the material of the plate body 1 is cobalt-chromium alloy.
[0043] Further, there are 14 retention holes 2 in number.
Embodiment 2
[0045] Such as Figures 1 to 5 As shown, the working principle and method of the present invention are as follows: the inner surface 3 of the plate body 1 is glued to the outside of the patient's posterior teeth, the bracket is connected to the outer surface 4 of the plate body 1, and the function of the retaining hole 2 is to bond the The adhesive is put into the retention hole 2 first, and then the plate body 1 is bonded to the outer surface of the posterior teeth, so that the adhesive enters the hole to realize the mechanical retention. If there is no retention hole 2, the bonding Force will drop obviously, and its reason is that under the situation that does not have retaining hole 2, the bonding agent between plate body 1 and posterior tooth is relatively thin and can cause, and plate body 1 falls off easily in oral cavity. Compared with the prior art, the present invention is installed on the outside of the back teeth, without contact with the gums and other parts, is no...
Embodiment 3
[0047] Such as Figures 1 to 3 As shown, the present embodiment provides a method for manufacturing an orthodontic bonding base, comprising the following steps:
[0048] S1. Prepare production materials and production equipment: prepare cobalt-chromium alloy powder; CAD / CAM equipment, grinding machine, sandblasting machine, corundum, grinding sandstone, metal polishing paste;
[0049] S2. Selection of abutment teeth and data collection: check the oral condition of the patient, select the abutment teeth, and use scanning equipment to collect data on the patient's dentition;
[0050] S3, utilize CAD (computer-aided design software) to design and manufacture the base electronic model;
[0051] S4, importing the electronic model of the substrate into CAM (Computer Aided Manufacturing System);
[0052] S5, using CAM (Computer Aided Manufacturing System) to control the 3D printing equipment to make the cobalt-chromium alloy powder into a base entity:
[0053] S6. The substrate is...
