Design method and preparation method of orthodontic appliance, orthodontic system

Abstract

The invention discloses a design method and a preparation method of a tooth straightener and a tooth straightening system. The design method includes: obtaining a digital dental model: obtaining a digital dental model, including a digital dental model body and a digital upper palate; designing a main body of a dental appliance: designing the posterior tooth area based on the digital dental model with at least The main body of the orthodontic appliance for one tooth to move in the distal direction, the main body of the orthodontic appliance includes a shell-shaped orthodontic appliance body and an auxiliary part body; an auxiliary anchorage part is set: a set of the auxiliary part body is provided on the auxiliary part body An auxiliary anchorage part that absorbs the reaction force generated when at least one tooth in the posterior region of the shell-shaped appliance body moves to the distal direction; an auxiliary conduction part is provided: an auxiliary conduction part is provided to guide at least one tooth in the posterior region to the distal direction Auxiliary conduction part for the reaction force generated when moving in the direction. The dental appliance obtained by the above design method can prevent the teeth in the anterior region from inclining to the labial side.

Description

Technical field [0001] Technical Field The present invention relates to medical devices, and particularly to a dental appliance design method and the preparation method, orthodontic system. Background technique [0002] Malocclusion is one of the three major oral diseases, a high prevalence. Most of malocclusion in growth and development, congenital malformations phenomenon caused by genetic factors or acquired environmental factors, malocclusion bring great harm to local or even systemic oral, maxillofacial such as the impact of development, the impact of oral health effects of oral function, appearance, etc. affect the appearance, at present mainly in patients with surgically or worn appliance for correction of malocclusion. [0003] In recent years, due to its invisible appliances can pick to wear comfortable to wear, and beautiful, more and more people choose. Orthodontic treatment process, and treatment applied to the teeth of any force to move in a direction opposite inevit...

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
