Description

Invisible orthodontic abutment without brackets using dental implant anchorage

technical field

The present invention relates to the technical field of orthodontics, in particular to a bracket-free invisible orthodontic abutment utilizing dental implant anchorage.

Background technique

In clinical practice, it is often encountered that the patient has been missing teeth for a long time and the adjacent teeth are inclined, the opposite teeth are elongated, leading to occlusal disorder, poor adjacency and insufficient restoration space, and problems such as "black triangle" of the gums will also occur, and the inclined adjacent teeth are borne by the patients. The direction of the occlusal force is not parallel to the long axis of the tooth, which will lead to excessive lateral force on the inclined adjacent teeth. At this time, the treatment method of minor tooth movement (MTM) is often used, that is, the orthodontic treatment of a simple dental deformity with a small range and distance of tooth movement, a single treatment target, and a simple method to restore the repair space, Establish normal adjacencies, gingival morphology and occlusion. Although the moving range and distance of the teeth are small, the teeth that need to be moved need precise control in the three-dimensional direction, and the teeth that do not need to be moved and the occlusal relationship need to be kept stable. It can be seen that the treatment of MTM is more difficult.

Bracketless invisible orthodontic treatment has outstanding advantages such as no wires and brackets in traditional orthodontic treatment, no impact on aesthetics, and full effect monitoring. The situation of tilted teeth is more common in adult patients. This part of the group has higher aesthetic requirements due to social needs, and has a higher tendency to choose invisible orthodontics without brackets. Invisible correction technology inherits the concept of traditional orthodontic mechanics, and is a perfect combination of computer-aided three-dimensional diagnosis, personalized design and digital molding technology.

At present, implant anchorage can provide absolute anchorage for partial orthodontic correction of inclined adjacent teeth and depression of opposing teeth before restoration, accurately control the movement of teeth, and maintain the stability of teeth and occlusion that do not need to be moved. It is invisible correction without brackets. A powerful tool for MTM. In clinical practice, both micro-implants and dental implants can provide implant anchorage. The surface of the micro-implant has been designed with a structure connected to the orthodontic device, which is widely used in clinical invisible orthodontics without brackets. structure to realize the combination of the form and function of the bracket-free transparent appliance and the dental implant. However, there is no similar structure on the market to realize the connection between the bracketless transparent appliance and the dental implant.
