Definitions

  • the present invention relates to a digital bracket for orthodontic treatment, and more particularly, to a digital bracket for orthodontic treatment with improved convenience and precision in orthodontic treatment.
  • occlusion refers to a state in which teeth of the upper jaw and the lower jaw mesh with each other when the mouth is closed.
  • malocclusion refers to an incorrect occlusion relationship that is functionally and aesthetically problematic because the arrangement of teeth is not aligned or the interlocking state of the upper and lower jaws is out of the normal position for some reason.
  • the cause of the malocclusion is known to have a large genetic influence, but may be caused by various causes such as problems with the shape or size of teeth, environmental influences, bad habits, wrong posture, and congenital disorders.
  • orthodontic treatment for treating the malocclusion uses the property of teeth moving when an external force is applied.
  • orthodontic treatment uses various devices and methods depending on the cause of malocclusion or the treatment period. For example, it may be classified into a device that inhibits or promotes the growth of the upper and lower jaw bones, or a device that gradually moves teeth to a desired position. In addition, it can be divided into a removable device that can be installed and separated in the oral cavity and a fixed device that is attached to the teeth and then removed at the end of treatment.
  • the fixed treatment method using the bracket is to attach the bracket to a tooth and move the tooth using the tension of a wire such as an orthodontic wire or a rubber band, and is commonly used in various types of orthodontic treatment.
  • brackets are firmly attached to the surfaces of the teeth to be aligned, and the wires are fixed to interconnect the brackets. And, by adjusting the tension applied to the wire to adjust the direction and magnitude of the force applied to the wire in various ways the tooth can be moved slowly. Therefore, the position and posture of the teeth are changed by the tension of the wire, and orthodontic treatment proceeds as the teeth are moved little by little.
  • the operator's experience and knowledge are qualitative data that are difficult to record as concrete data, and differ according to the operator's individual abilities and experiences. For this reason, since the desirable dental model itself, which is the final goal of orthodontic treatment, is formed by the operator's subjective viewpoint or experience, there is a problem in that orthodontic treatment is not universal and objective.
  • the bracket is attached to the tongue or labial surface of the tooth through an adhesive, and after the bracket is attached and fixed to the tooth, the wire is ligated to the bracket.
  • a slit is opened in the bracket, and the wire is inserted and fastened into the slit.
  • the slit is formed including a passage through which the wire is introduced and an inner end into which the wire is inserted and fixed.
  • the passage is opened with a narrower width than the inner end portion.
  • the thickness of the portion where the inner end is formed is thin. For this reason, there is a problem in that the bracket is fractured while the tension of the wire is applied to the bracket.
  • bracket is manufactured to be thick, there is a problem in that the feeling of foreign matter increases when attached to the teeth, and the discomfort of the person to be treated increases. In addition, there is a problem in that the bracket is separated from and separated from the tooth due to repeated contact or interference of the opposing tooth or tongue with the bracket.
  • the bracket in orthodontic treatment, the bracket must be attached to an accurate position in order to move the position of the tooth through the tension of the wire.
  • a jig for guiding and attaching the bracket to the correct position of the tooth is provided.
  • the jig is connected to the bracket and separated from the bracket and the tooth after the attachment of the bracket is completed.
  • the jig is formed substantially integrally with the bracket.
  • an inner surface where the bracket and the jig are connected has been formed in a continuous contour that matches the tooth surface.
  • the bracket is attached with an adhesive, and the adhesive is applied or dripped between the bracket and the tooth. Subsequently, the bracket is pressed so that the inner surface of the bracket is closely attached to the tooth surface through the adhesive.
  • the adhesive is hardened through natural light or a photocuring device, and through this, the bracket can be attached to the tooth surface.
