Correction appliance machining method and correction appliance machining system

Abstract

The invention relates to the technical field of medical treatment, and discloses a correction appliance machining method and a correction appliance machining system. In an execution mode of the invention, the correction appliance machining method comprises the following steps: scanning a correction appliance model on which a correction appliance template in a sleeving way, and acquiring a three-dimensional model image of the correction appliance model; acquiring a correction appliance model image matched with the three-dimensional model image from a prestored correction appliance model database, and determining a cutting trace of the correction appliance template according to the correction appliance model image; cutting the correction appliance template according to the cutting trace. By adopting the execution mode of the invention, automatic cutting of the system for machining the correction appliance on the correction appliance template is realized, the intelligent degree is higher, the phenomenon of more tailoring, more grinding or less tailoring when the correction appliance template is manually tailored according to experience can be effectively avoided, and the reject ratio and the labor cost of product production are reduced.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a processing method and system for an orthotic. Background technique [0002] Orthodontic appliances, as a medical tool for correcting the alignment of teeth, have been widely used. At present, aligners are generally made of resin molds, and the resin molds are generally press-molded first, and the excess resin molds are cut off after compression molding, and then polished. [0003] However, the inventors of this patent application have found that the prior art has at least the following defects: [0004] In the prior art, when cutting and polishing the appliance, most of them are cut by workers according to experience along the tooth contour after the resin mold is molded, so it often results in excessive cutting, grinding or grinding of the resin mold. The phenomenon of less cutting, the defective rate of product production is high, and the labor cost is high. Moreover, whe...

Problems solved by technology

[0004] In the prior art, when cutting and polishing the appliance, most of them are cut by workers according to experience along the tooth contour after the resin mold is molded, so it often results in excessive cutting, grinding or grinding of the resin mold. The phenomenon of fewer cuts, the defective rate of product production is high, and the labor cost is high

Moreover, when there is excessive cutting and grinding of the resin mold, it will easily damage the crown part of the resin mold, which will not only affect the appearance of the appliance, but also affect the comfort of the user when wearing the appliance; When there is less cutting of the resin mold, it is often necessary to cut and polish the resin mold again, which will prolong the production time of the appliance
