Titanium alloy denture bracket and manufacturing method thereof

Abstract

The invention discloses a titanium alloy false tooth bracket, which comprises a jaw plate matched with the patient's inner jaw, the outer side of the jaw plate has an arc-shaped edge matched with the neck contour of the remaining teeth, and dentures for covering the gingiva of missing teeth Mounting position, the titanium alloy denture bracket is molded by additive manufacturing using titanium alloy powder, the denture mounting position includes an anterior tooth mounting position, and a support frame is provided in the anterior tooth mounting position, and the titanium alloy denture bracket has high manufacturing precision , the surface is smooth and flat; the dentures are firmly installed, easy to wear, and firmly fixed to the oral cavity; the production of dentures takes a short time and is low in cost, which is a qualitative leap compared with the existing denture brackets.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a titanium alloy denture bracket and a manufacturing method thereof. Background technique [0002] The production method of removable dentures under the traditional technology is as follows: first, cast a bracket that fits the oral cavity, and the bracket has a mounting position covering the gingiva of the edentulous area, and the bottom surface of the mounting position is usually provided with structures such as grids or slots It is used to bond the dentures in the installation position, but when installing the anterior teeth in this way, due to the small area at the bottom of the anterior teeth, the bonding force is low, and because the anterior teeth usually have a certain forward angle when installed, it is difficult to Dentures need to bear a lot of lateral force when biting, and they are easy to fall off due to excessive force, which affects the daily life of patients.

Problems solved by technology

[0003] The problem to be solved by the present invention is to provide a titanium alloy denture bracket and its manufacturing method, which can effectively increase the firmness of the anterior denture. In addition, the denture bracket also has the advantages of high manufacturing precision, fast manufacturing speed and low cost. The present invention solves this technical problem in the following way: a titanium alloy denture bracket, comprising a jaw plate matched with the patient's inner jaw, the outer side of the jaw plate has an arc-shaped edge matched with the contour of the neck of the retained tooth and is used to cover The denture installation site for missing teeth and gums is characterized in that: the titanium alloy denture bracket is made of titanium alloy powder through 3D additive manufacturing, and the denture installation site includes the front teeth installation site, and an integrated Formed support frame, when installing the front teeth dentures, inject molten resin glue into the front teeth installation position, then put the front teeth denture cover with slots in the middle on the support frame and adhere to the resin glue to complete the dentures The support frame installed in the denture plays the role of tooth root retention, making the denture stronger. The 3D additive manufacturing process of titanium alloy powder solidified by laser ablation has the advantages of fast manufacturing speed, easy manufacturing and high manufacturing accuracy. The high feature solves the problem of cumbersome and poor precision in the traditional reverse casting process, and also makes it possible to set the support frame in the installation position of the anterior teeth, which will inevitably cause the problem of breakage of the support frame in the traditional casting process. As mentioned above, compared with the existing denture brackets, the denture bracket of the present invention has achieved a leap in quality, strength and cost.
