Abstract

The invention is suitable for the technical field of invisible tooth appliance processing, and provides an invisible tooth appliance solid model recognition processing technology. The technology comprises the following steps: sequentially scanning model contours to generate three-dimensional images, and carrying out identifiable positioning on positioning reference points marked on a model; matching the three-dimensional images generated by scanning with a preset model database, determining a database model to perform datum point matching positioning, and obtaining a paired database model; carrying out cutting contour line setting through the paired database models, and transmitting set contour line data to an automatic mechanical arm; and carrying out trajectory cutting of the mechanicalarm according to set contour line data and coordinate datum points. According to the method, the production efficiency of a traditional production process is improved, and machining failures caused bythree-dimensional coordinate errors or identification recognition errors in identification type information scanning and positioning are reduced.

Description

technical field [0001] The invention belongs to the technical field of invisible tooth aligner processing, and in particular relates to a process for identifying a solid model of an invisible dental aligner. Background technique [0002] Dental Invisible Orthodontic Appliance is a device for treating malocclusion, which can be called orthodontic appliance. It can produce force, or the functional force of the masticatory perioral muscle can change the deformed jaw, misplaced teeth and periodontal support tissue through the appliance, so as to facilitate the normal growth and development of the tooth and maxillofacial surface. An appliance is usually a flexible wire and bracket, or a mechanical device combined with a plastic base, worn in the mouth or maxillofacial area. [0003] In the production line for the processing and production of invisible orthodontic appliances, most of them are completed manually using electric tools, and some automated production relies on pre-exi...
