Orthodontic appliance design method, preparation method, and orthodontic system

Abstract

The invention discloses an orthodontic appliance design method, a preparation method, and an orthodontic system. The orthodontic appliance design method comprises the following steps: acquiring a digital dental model which comprises a digital dental model body and a digital palate part; designing an orthodontic appliance main body which is at least provided with one tooth in a posterior tooth areato move towards a distal direction based on the digital dental model, wherein the orthodontic appliance main body comprises a shell-shaped orthodontic appliance main body and an auxiliary part main body; arranging an auxiliary anchorage part, wherein the auxiliary anchorage part is arranged on the auxiliary part main body which can absorb counter-acting force generated by the tooth on the rear tooth area of the shell-shaped orthodontic appliance main body when the tooth moves towards the distal direction; arranging an auxiliary conduction part which is used for assisting in conducting the counter-acting force generated when at least one tooth in the rear tooth area moves towards the distal direction. The orthodontic appliance obtained by the design method can prevent the teeth in the anterior tooth area from inclining towards the lip side.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a design method and preparation method of a dental appliance and a dental appliance system. Background technique [0002] Dental deformity is one of the three major diseases of the oral cavity and has a high prevalence rate. Most dental and jaw deformities are deformities caused by congenital genetic factors or acquired environmental factors in the process of growth and development. Dental and jaw deformities bring great harm to the oral cavity and even the whole body, such as affecting the development of the maxillofacial and oral cavity. Health, oral function, and appearance are affected. At present, patients mainly correct dental and jaw deformities through surgery or wearing appliances. [0003] In recent years, invisible orthodontic appliances have been chosen by more and more people because they are comfortable to wear, removable and beautiful. In the process of o...

Problems solved by technology

However, the above-mentioned control methods have the following problems: increasing the number of anchorage teeth can only be applied to a small number of cases; the method of preparation for anchorage is difficult to accurately control the increase of anchorage units when the anchorage is insufficient, thereby causing uncertainty in the treatment results; Because the way of traction between the upper jaw (or lower jaw) and the lower jaw (or upper jaw) lead at the same time, there will be some side effects when used; the implant anchorage needs to damage the implant in the patient's mouth, some patients do not accept it, and The operation has relatively high requirements for doctors; therefore, there are some problems in the above-mentioned control methods in the process of personalized correction

In fixed orthodontics, in addition to implant anchorage, the commonly used methods of anchorage control include the addition of trans-palate anchorage (TPA) and Nance bow devices in the mouth. It works very well, but because it has to be fixed with the molars, it affects eating and oral hygiene, and the patient feels poor
