Technical Field

The invention relates to the field of oral clinical orthodontics, in particular to a self-filling bracket-free invisible appliance for orthodontics.

Background

With the change of the dietary habits and life styles of people and the insufficient attention on oral hygiene, the teeth deformity is common, and the occurrence of the teeth deformity has great adverse effect on the life quality of patients; the orthodontics in oral clinical medicine refers to the orthodontics of the originally irregular teeth of a patient by a tooth appliance, so that the teeth are arranged in order.

The traditional tooth orthodontic mode is orthodontic bracket, each bracket is fixed on the surface of the tooth through adhesive, and an arch wire passes through the groove of each bracket to exert various types of orthodontic force on the tooth, so that the tooth is straightened. However, the orthodontic mode has great influence on daily life and diet of a wearer, and has poor aesthetic property, the wearer is easy to generate psychological conflict and the orthopedic effect is influenced, on the basis, a bracket-free invisible appliance appears on the market, the bracket-free invisible appliance is a tooth sheath structure which is attached to an orthopedic structure and is obtained by using a computer-aided printing design combined 3D scanning technology, high polymer plastic is used as a raw material for customization, the material has high transparency, is safe, sanitary, moderate in strength and elasticity, not only can control the size of the orthodontic force, but also can control the acting time of the orthodontic force, the dislocation and distortion teeth are gradually corrected by using the material resilience characteristic of the high polymer plastic, the tooth movement can be finely controlled, and the aim of correcting the teeth through small-range tooth movement is achieved by continuously adjusting a plurality of the bracket-free appliances, the correction is effectively completed.

However, the existing bracket-free invisible appliance can only perform orthodontic correction operation on deformed teeth, while in actual oral clinical operation, tooth deformity is accompanied with decayed teeth, and the decayed teeth are required to be maintained while the orthodontic correction operation is performed. The bracket-free invisible appliance is almost in a full wrapping state with the surface of a tooth in the wearing process, and in order to achieve the correction effect, the wearing time of the bracket-free invisible appliance body can not be less than 20 hours every day, so that the problems that food residues are left on the surface of the tooth, bacteria are easy to breed, the environment outside the tooth is not clean and the like are caused, and the health of the tooth is influenced. Therefore, it would be a technical advantage if a denture-free invisible appliance of the caries maintenance type could be designed.
