Method and system for determining target dentition layout

Abstract

The invention provides a method and system for determination of object dentition layout. The method comprises receiving an original data set representing original dentition layout, wherein the original data set comprises a data set representing an original position of at least one key tooth, acquiring a parameter set representing a head structure, ensuring a data set representing an object position of at least one key tooth through the parameter set according to the data set representing an original position of at least one key tooth, and producing an object data set representing object dentition layout according to the data set representing an object position of at least one key tooth. The method and system allow fast, convenient and automatic or semi-automatic determination of object dentition layout, put the concept of biological integral correction into a tooth fixing correction and invisalign computer-based tooth arrangement design and improves tooth correction design bio-safety, reasonability and effectiveness.

Description

technical field [0001] The present invention generally relates to the technical field of orthodontics, and specifically, the present invention relates to a method and a system for determining a target dentition layout according to target positions of several key teeth. 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 for orthognathic deformities mostly use fixed brackets that are bonded to the teeth. Compared with the traditional fixed bracket orthodontic technology, the new invisible orthodontic technology does not require brackets and steel wires, but uses a series of invisible orthodontic appliances, which are made of safe elastic transparent polymer materials. The orthodontic process is almost completed without being noticed by others, and will not affect daily life and social interaction; and because patients can take off and wear them by themselves, ...

Problems solved by technology

[0004] Although it is an intuitive approach to set the target position based on the initial position and then produce the intermediate position, the current method for determining the target position is to mechanically simulate the set-up target by the designer according to the clinician's requirements position, while the designer mainly considers the mechanical movement and mathematical problems of the teeth in the design of the tooth arrangement, and hardly considers the angle / position relationship between the tooth root and the alveolar bone, the health of the soft and hard tissues of the oral cavity, and the health of the joints. Sexual structure issues and facial aesthetics issues

Moreover, the level of clinicians varies, and the degree of control over the results of tooth placement is uneven; therefore, the orthodontic appliance worn by the patient is likely to fail to achieve a good orthodontic effect due to insufficient control of the clinician's medical technology and aesthetic principles. Extended treatment period

[0005] Furthermore, the pre-determined target position is not necessarily a target position that can be reached medically or can be reasonably reached, which makes it impossible or difficult to achieve the above-mentioned manually determined target position medically.
