Smoothing processing method for edges of appliance

Abstract

The invention discloses a smoothing processing method for edges of an appliance. The method comprises the steps as follows: rough grinding is performed on the brace edges of the appliance with the edges to be subjected to smoothing processing through a columnar sandstone bur, and a rough-ground appliance is obtained; the revolving speed of the columnar sandstone bur is higher than 3,500 rps; and secondary grinding is performed on the rough-ground appliance through a corundum bur with the outer wall sleeved with an absorbent ball, and the appliance with the edges subjected to smoothing processing is obtained. With the method, secondary grinding is performed through the corundum bur with the outer wall sleeved with the absorbent ball, all that is required for realizing of the surrounding effect for all surfaces is to slightly roll the bur over the brace edges, the smooth effect can be realized through once to twice grinding, and the detail processing capability for the brace edges is also greatly improved.

Description

technical field [0001] The invention relates to the technical field of dental processing, in particular to a processing method for smoothing the edge of an appliance. Background technique [0002] The treatment of the edge of the braces generally uses a columnar sandstone bur. First, the excess part of the edge of the braces is quickly ground at a speed of 3,000 rpm or more, and then repeatedly ground at a speed of 1,500 rpm to remove the appliance. The flash and sharp parts of the edge make it form a rounded and smooth edge effect. However, due to the relatively thick material of the bur, this technology takes a long time to process in practice, the edge is not smooth enough, and the ability to handle details is insufficient, which often leads to poor oral comfort and even damage to the soft tissues in the oral cavity. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the above deficiencies in the p...

Problems solved by technology

[0004] In view of the above deficiencies in the prior art, the purpose of the present invention is to provide a method for smoothing the edge of the aligner, which aims to solve the problem that the edge of the braces in the prior art generally uses a columnar gravel bur, which takes a long time to process and has a smooth edge. The degree is not ideal, and the ability to deal with details is insufficient, which may easily lead to poor oral comfort and even damage to the soft tissues in the oral cavity.
