Embodiment Construction

[0031] Such as Figure 4 As shown, the invisible aligner without brackets for guiding the movement of the lower jaw includes an upper jaw brace 1 and a lower jaw brace 2. The upper jaw brace 1 has an upper protrusion 11, and the lower jaw brace 2 has a lower protrusion 21. The upper jaw brace 1 and the lower jaw brace have a lower protrusion 21. 2 When snapping together, the upper protrusion 11 and the lower protrusion 21 are in contact. The distance between the upper protrusion 11 and the lower protrusion 21 is the distance to be corrected. When the upper and lower jaws occlude, the upper protrusion 11 and the lower protrusion 21 are pressed against each other. The upper protrusion 11 is behind, the lower protrusion 21 is in front, and the lower protrusion 21 is in front. The protrusion 21 is continuously pushed forward, and the force received by the lower protrusion 21 is transmitted to the mandibular brace 2 and then to the mandible, so that the mandible moves. When it is ...

Abstract

A bracketless invisible appliance for guiding lower jaw to move includes an upper jaw tooth socket and a lower jaw tooth socket. The upper jaw tooth socket has an upper protrusion, and the lower jaw tooth socket has a lower protrusion. When the upper jaw tooth socket and the lower jaw tooth socket are occluded, the upper protrusion makes contact with the lower protrusion. The bracketless invisibleappliance has the advantages of good wearing comfort, no influence on the daily life of a wearer, and improvement of guiding lower jaw to move with mandibular retrusion.

Description

technical field [0001] The invention relates to the field of orthodontics, in particular to a bracketless invisible appliance for guiding mandibular movement and a manufacturing method thereof. [0002] technical background [0003] Dental and maxillofacial deformities in early childhood development are mainly caused by bad oral habits or abnormal functions, manifested as abnormal dental arch shape or positional relationship between jaws. At present, the main treatment methods are headgear-muscle activator, twinblock appliance, bioregulator, Frankel function regulator, etc. [0004] The cranial-muscle activator consists of a non-mechanical plastic base with the maxillary part covering the entire palate and the mandibular part extending down to the floor of the mouth. The base is distal to the first permanent molar. The base includes an upper base and a lower base. The upper and lower bases are connected to form a plastic cap for the lower incisors in the anterior region to ...
