Problems solved by technology

[0004] At present, the application of invisible orthodontic technology is still a situation of separation of "medical" and "system". The diagnosis plan is determined by the orthodontist in the hospital, and the manufacturer makes a matching invisible appliance according to the doctor's treatment plan. This process is: doctor's diagnosis, Determine the plan, send the data to the manufacturer, the manufacturer processes and produces, and sends it back to the doc

Embodiment Construction

[0023] The system for manufacturing the dental appliance and the method for manufacturing the invisible appliance using the system are described in detail below.

[0024] The system of the present invention for making dental appliances includes a data acquisition system, a modeling system, a model making system, a hot press forming system and a detection system;

[0025] The data acquisition system includes a system for collecting dental jaw data of the patient to be corrected, and using reverse software to transform the obtained dental jaw data into a three-dimensional model, and then presenting the patient's dental jaw data for diagnosis by the orthodontist through a certain processing method And formulate the initial digital dental model of the treatment plan;

[0026] In the actual data collection process, first add a portion of water to the material to be removed from the impression according to the proportion, and make it into a viscous shape for impression use. Fill the impres...

Abstract

The invention discloses a system for manufacturing teeth correcting equipment and a method for preparing the concealed teeth correcting equipment by the system. The system comprises a data acquisition system, a modeling system, a model making system, a thermoplastic forming system and a detection system. The manufacturing method includes the steps: acquiring initial oral cavity state information and building an initial digital model of upper and lower jaws; designing the ideal state of each tooth and making a standard digital model according to oral conditions; designing a series of stage digital models between the initial digital model and the standard digital model; manufacturing the needed concealed teeth correcting equipment according to a series of solid dental models. The stage digital models represent preset target situations at different correcting stages, and the solid dental models are made by a 3D (three-dimensional) printing DLP (digital light processing) surface exposure process. The teeth correcting system can correct patients in any age groups.

Description

Technical field [0001] The invention relates to the fields of orthodontic treatment and additive manufacturing, and in particular to a system for manufacturing a dental appliance and a method for manufacturing an invisible appliance using the system. Background technique [0002] Dental malformation is one of the main oral diseases and has a high prevalence. Traditional orthodontic deformity correction methods mostly use fixed bracket appliances that are bonded to the teeth. The disadvantage is that the wires are exposed, and the wires often come out to wipe the lips, which not only affects the appearance but also causes damage to the lips; at the same time, the need for appliances Long-term adhesion to the teeth will cause great difficulty in cleaning the teeth during the entire orthodontic process. Once the cleaning of the teeth cannot be guaranteed, the teeth will be demineralized and discolored; moreover, the doctor needs to be in each stage of the orthodontic process To adj...
