Preparation method of muscular function appliance and material preparation process of muscular function appliance

Abstract

The invention discloses a preparation method of a muscular function appliance and a material preparation process of the muscular function appliance, which comprises the following steps: acquiring scanning data of teeth in an oral cavity through an intraoral scanner, performing structural modeling of the muscular function appliance, reserving a growth and development space in the structural modeling, and then manufacturing a mold; the preparation method comprises the following steps: mixing and uniformly stirring two components of polyurethane materials according to a formula proportion, pouring the polyurethane materials into a mold coated with a release agent in a liquid state, putting the poured mold into a drying oven for curing, and after curing is completed, demolding and taking out the manufactured muscular function appliance. According to the muscular function appliance disclosed by the invention, the prevention and treatment of malocclusion are realized by breaking bad oral habits and helping a patient to develop a good chewing habit; the orthodontic appliance has the advantages that the orthodontic appliance can be better matched with tooth, dental arch and intraoral conditions of a patient, enough space is reserved for growth and development according to the age stage of the patient, so that better comfort and wearing effects are achieved, and hindrance of a traditional orthodontic appliance of a fixed model to growth and development can be reduced.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to a material of a muscle function appliance applied to children's orthodontics and a material preparation process thereof. technical background [0002] The existing muscle function appliance is made of thermoplastic polymer material or silica gel material, and is produced by injection molding or high-pressure injection. This technology has the following defects: 1. It can't realize customized and personalized production, patients can only choose their own similar models, and the wearing comfort and correction effect can't reach the expectations. 2. It is impossible to adjust local features according to doctors' needs and realize special functions. [0003] With the development of new materials and the progress of 3D printing technology, combined with the shape and growth law of children's teeth and dental arch, a personalized muscle function appliance can be designed to correct bad hab...
