Technical Field

The invention relates to the field of oral medical treatment, in particular to a film taking method of an invisible orthodontic appliance based on laser cutting.

Background

Digital invisible orthodontic appliances which have emerged in recent years have been widely popular and are gradually replacing, to some extent, traditional "steel wire mouthpiece" appliances. On the manufacturing process of the invisible orthodontic appliance which is mainstream at present, the membrane taking of the appliance is time-consuming and labor-consuming work, after the film pressing process is completed, a worker firstly cuts the membrane by using scissors, then breaks the membrane off from a tightly attached dental cast by hands, finally, a polishing pen is used for repairing the membrane along a gum line, and the membrane after being polished can become the invisible orthodontic appliance. The traditional membrane taking method is low in efficiency and not beneficial to batch production, and deformation of the appliance is easily caused in the membrane taking process, so that the use effect of the appliance is influenced. In conclusion, it is very important to design a film taking method which is convenient for taking the film of the invisible orthodontic appliance and is beneficial to automatic mass production.

Disclosure of Invention

In order to solve the technical problems, the invisible orthodontic appliance film taking method based on laser cutting is provided, so that deformation of the appliance in the film taking process can be eliminated, the edge of the appliance can be formed beautifully, more importantly, the film taking efficiency is greatly improved, and the film taking method can meet the requirements of automatic production.

In order to achieve the purpose, the technical scheme of the invention is as follows:

a film taking method of an invisible orthodontic appliance based on laser cutting comprises the following steps:

obtaining a digital model of the jaw of the patient by oral cavity scanning or impression taking;

1) obtaining a digital model of the jaw of the patient by oral cavity scanning or impression taking;

2) forming the digital dental model into a solid dental model through 3D printing;

3) placing the dental cast in a film pressing machine for film pressing to obtain the invisible orthodontic appliance;

4) drawing a black line along a gum line on the appliance closely attached to the dental cast;

5) under the control of the visual positioning laser cutting control system, the laser cutting head cuts the orthodontic appliance along the black line to finish the separation of the orthodontic appliance and the dental cast.

Further, the light source of the laser cutting head is a CO2 laser.

Further, the laser cutting head comprises a manipulator which is used for operating the laser cutting head.

According to the technical scheme, the film taking method of the invisible orthodontic appliance based on laser cutting eliminates deformation of the appliance in the film taking process, omits the process of polishing with a polishing pen and trimming, optimizes formation of the appliance, greatly improves processing efficiency of the appliance, and is suitable for batch production of the appliance.
