An aspect of the present invention is a drill assistance device comprising: a drill guide device that serves as a guide when forming a plurality of holes from a curved surface of a hard palate having the curved surface; and a guide sleeve that is fitted in the drill guide device in an attachable and detachable manner. With this device, it is possible to easily and accurately perform the hole making with a drill and the implant of a screw in an oral cavity. The drill guide device comprises: a guide frame unit that is formed by connecting a plurality of tubular guide frames to each other; a fixing member to be capped on a tooth of a patient; a connecting portion that connects the guide frame unit and the fixing member and determines arrangement of the guide frame unit on the curved surface; and at least one protruding portion that holds the guide sleeve inserted in any of holes inside the guide frames. The guide sleeve comprises: a tubular sleeve main body having an inner diameter that allows the drill to be inserted and an outer diameter that allows the sleeve main body to be inserted in any of the guide frames; a water injection slit that is provided in the sleeve main body; and projecting portions that are each fitted in at least one recessed portion provided in the at least one protruding portion when the sleeve main body is inserted in any of the holes of the guide frames.

An orthodontic appliance is provided and includes: a base member fixed to two or more screws implanted in a vicinity of median palatine suture of a palate bone; an arm-shaped arm member having a first connecting portion connected to the base member and a second connecting portion located in a vicinity of palatal side of a tooth; and a traction member that is made of an elastic wire material and pulls a tooth as the traction target. The traction member has a traction base portion, a traction fixation portion, and a traction force generation portion. The traction fixation portion has a bent portion in which the wire material extending along dentition is plastically deformed and bent toward a tooth root side. The bent portion is hooked on a protruding portion protruding to a palate side in a bracket.

An embodiment of the present invention is a drill assistance device that is provided with a drill guider that serves as a guide when forming multiple holes from the curved surface of the hard palate, which has a curved surface, and a guide sleeve that is detachably fitted into the drill guider. The device is capable of easily and accurately drilling with a drill and implanting screws in the oral cavity. The drill guider is provided with: a guide collar unit formed by connecting multiple cylindrical guide collars to each other; fixing members to be capped on the patient's teeth; connectors that connect the guide collar unit to the fixing members and determines the location of the guide collar unit on the curved surface; and projections for holding the guide sleeve when inserted in a guide collar. The guide sleeve is provided with: a cylindrical sleeve body with an internal diameter in which the drill can be inserted and an external diameter that can be inserted in a guide collar; a water-filling slit provided in the sleeve body; and protrusions that fit together with a crevice provided in the projection when the sleeve body is inserted in a hole.

One aspect of the present invention is a self-ligation type orthodontic bracket which has a simple structure and in which a shutter can be reliably opened and closed, and fixed. The orthodontic bracket is provided with: a bracket body having a slot to which a wire is attached and an introduction port connected to the slot; a shutter provided between the slot and the introduction port to be able to move forward and backward; and a stopper wire which is attached to the bracket body and prevents the shutter from detaching. The stopper wire is elastic. Both end parts of the stopper wire are supported by the bracket body. When the shutter is closed, the central part of the stopper wire is located at a position which blocks the path along which the shutter moves forward and backward.

The present invention provides an orthodontic device based on a novel orthodontic technique, the device being provided with: a base member that is fixed to two or more screws embedded in the vicinity of the median palatine suture between the bones forming the palate; an arm-like arm member that has a first connection portion connected to the base member and a second connection section located in the vicinity of the palate side of teeth; and a pulling member that is made of an elastic wire material, and pulls a tooth to be pulled. The pulling member has: a pulling base fixed to the second connection section; a fixed pulling portion locked to a bracket fixed to an object to be pulled, which is located away from the pulling base; a pulling force generation unit that is located between the pulling base and the fixed pulling portion, and applies backward pulling force and forward rotation force or forward pulling force and backward rotation force to the bracket through the fixed pulling portion. The fixed pulling portion has a curved section that is bent toward the dental roots by plastic deformation of the wire material extending along the teeth. The curved section is locked to a protrusion of the bracket, the protrusion protruding toward the palate.

A base member for an orthodontic implant device. The base member makes it possible to easily and reliably attach a correction implement. The base member is secured by a plurality of screws that are embedded in a bone inside an oral cavity. Each of the plurality of screws has a screw part that is embedded in the bone and a polygonal-columnar head part that is exposed inside the oral cavity. The base member has at least three engagement holes that are provided so as to be capable of engaging the polygonal-columnar head parts and such that the centers thereof are not on the same straight line.

A self-ligating orthodontic bracket that can be used for accurate correction. The orthodontic bracket comprises a bracket main body and a shutter. The bracket main body has: a slot for attaching a wire; and an introduction opening that communicates with the slot. The shutter is retractably provided between the slot and the introduction opening of the bracket main body. The bracket main body has an outside guide wall that forms the slot and the introduction opening. The shutter is inserted through a through hole that is provided in the outside guide wall. When the shutter is to be closed, a tip part of the shutter that protrudes from the insertion hole to the slot side is moved in a first direction, which is oriented from the introduction-opening side toward an opening-part side, so as to cover the slot.
