Direct step-by-step method for generating orthodontic states

Abstract

The present invention provides a method for generating a state of orthodontic treatment, comprising the following steps: receiving a digital model representing the current state of teeth; The number of treatment steps from the tooth state to the desired tooth state, and K is an integer greater than or equal to 1; for each treatment step-by-step parameter, a set of digital models representing the tooth treatment state set corresponding to the treatment step-by-step parameter is generated, so that K groups of digital models; and from the K groups of digital models, selecting a digital model representing the best set of orthodontic states. And the present invention also provides a method for manufacturing a dental appliance based on the obtained dental orthodontic state, and the dental appliance manufactured according to the method.

Description

technical field [0001] The present invention generally relates to the field of oral clinical orthodontics, and in particular, the present invention relates to a method for producing a series of orthodontic states. Furthermore, the present invention also relates to a method for manufacturing a dental appliance based on the obtained orthodontic state, and a dental appliance manufactured according to the method. Background technique [0002] Dental deformity is one of the three major diseases of the oral cavity and has a high prevalence rate. The traditional orthodontic methods mostly use fixed brackets that are bonded to the teeth. The disadvantage is that the steel wires are exposed, which affects the appearance. At the same time, because the orthodontics are glued to the teeth for a long time, they cannot be removed during the whole orthodontic process. Oral hygiene is difficult to maintain well, and it is easy to breed plaque and cause tooth demineralization and discolorat...

Problems solved by technology

Although it is intuitive to manually set the target position through the initial position and then produce the intermediate position, this separation of the target position and the intermediate position does not achieve the overall optimality of the two.

Moreover, after determining the target position, the method uses an interpolation method to calculate the intermediate position. This interpolation method does not guarantee that the final path is optimal, and there may be fewer intermediate positions to reach the target position.

Furthermore, the pre-determined target position is not necessarily a target position that can be reached medically or that can be reasonably reached, thus making it impossible or difficult to achieve medically.
