Technical Field

[0001] The utility model relates to the technical field of invisible orthodontic appliances, in particular to a bracket-free invisible orthodontic appliance with a pressure ridge. Background Art

[0002] As people pay more and more attention to aesthetics, they not only have requirements for the neatness of teeth, but also begin to have requirements in the selection of braces. As a result, people are not limited to choosing traditional fixed orthodontic appliances composed of nickel-titanium alloy archwires and metal brackets. More and more people choose bracketless invisible braces that are beautiful, comfortable and easy to remove.

[0003] Bracketless invisible orthodontic technology is one of the cutting-edge technologies in the field of orthodontics. Its corrective force comes from the rebound force generated by the deformation of the hot-pressed film material, which is equivalent to the rebound force brought by traditional nickel-titanium alloy. However, bracketless invisible orthodontic appliances lack the auxiliary devices used in traditional brackets, such as torque control devices, flat guide devices, jaw pad devices, and lingual buckle devices. This will result in that the movement of teeth cannot be well controlled, there is no effective protection against the adverse movement of the tooth roots, and root bone fenestration and bone cracks also occur from time to time.
