Apparatus, devices, or methods used for one or more of the following:

  • correcting abnormalities or injuries that prevent the proper or desired bringing together of the cooperating surfaces of natural teeth, or their artificial replacements that are permanently affixed within the mouth, located on opposite jaws;
  • preserving or rectify the appropriate or desired relative positioning, separation gaps, or alignment of natural teeth; or
  • preventing or repairing damage to natural teeth or their appropriate or desired relative positioning, separation gaps, or alignment (e.g. devices that surround or cover teeth to prevent grinding).
