Manufacturing method of invisible tooth correcting treatment devices

Abstract

The invention discloses a manufacturing method of invisible tooth correcting treatment devices. According to the method, firstly, an original odonto-maxillary three-dimensional model of a patient is built through a correcting treatment objective and an original odonto-maxillary three-dimensional model; secondly, correcting treatment odonto-maxillary models in different stages of the correcting treatment process are built; then, corresponding three-dimensional printing models are built; corresponding invisible tooth correcting treatment devices are respectively printed out by medial polyethylene according to the three-dimensional printing models; and finally, the invisible tooth correcting treatment devices are polished and ground and are delivered to the patient to be used. By using the method, the invisible tooth correcting treatment devices are directly manufactured without using a solid body objective model, so that the consumption of a great number of light-cured resin materials is avoided; and the problems of high cost and complicated production process of the invisible tooth correcting treatment devices are solved.

Description

Technical field [0001] The invention belongs to the field of orthodontics, and more specifically, relates to a manufacturing method of an invisible appliance. Background technique [0002] Bracket-free invisible orthodontics were first introduced by the American AlignTech company in 1998, and then introduced into the domestic market by the Capital Medical University and Beijing Times Angel Company, and have been promoted and used in China since 2006. Compared with the traditional fixed bracket orthodontics technology, which is fixed orthodontics or braces, the invisible braces without brackets are safer and more comfortable, and will not cut the oral tissue due to the fixed brackets. At the same time, the bracketless invisible appliance will not affect the aesthetics of the oral cavity after being worn by the patient. The patient can take the belt by himself, is convenient to wear, the chairside operation time is short, and there is no need for frequent follow-up visits, so the ...
