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.

Provided herein are curable compositions for use in a high temperature lithography-based photopolymerization process, a method of producing crosslinked polymers using said curable compositions, crosslinked polymers thus produced, and orthodontic appliances comprising the crosslinked polymers.

A method for providing an orthodontic appliance includes: a step of creating three-dimensional data for an auxiliary mouthpiece and three-dimensional data for an orthodontic mouthpiece based on an intraoral shape and a shape and a bonding position of a protruding piece to be bonded to an orthodontic target tooth; a step of forming, based on the three-dimensional data for the auxiliary mouthpiece, the auxiliary mouthpiece including a recessed portion that corresponds to the protruding piece; and a step of forming, based on the three-dimensional data for the orthodontic mouthpiece, the orthodontic mouthpiece including a pressing portion that comes into contact with the protruding piece.

An orthodontic appliance and uses thereof are disclosed. The first orthodontic appliance includes a shell-like body at least having a geometric structure allowing at least one tooth in a posterior region to move in a distal direction. The shell-like body is further provided with an auxiliary anchoring portion capable of absorbing a reaction force generated by the at least one tooth in the posterior region while moving in the distal direction. Provided between the shell-like body and the auxiliary anchoring portion is an auxiliary transmitting portion used for aiding transmission of the reaction force generated by the at least one tooth in the posterior region while moving in the distal direction.

Methods and systems for creating orthodontic aligners with specific tongue spikes that work alone or in combination with other tongue spikes to provide protection against tongue thrust and to correct tongue thrust are disclosed. Three-dimensional computer modeling software is used to modify a three-dimensional model of the patient's teeth by creating a desired tongue spike and digitally adding a tongue spike to a tooth to protect the orthodontic aligner from forces resulting from tongue thrust.

Embodiments of the present invention provide devices (tags), systems, and methods to determine structural integrity and other states of orthodontic-elements, such as orthodontic-brackets, orthodontic-archwires, orthodontic-expanders, orthodontic-elastic-bands, and orthodontic-power-chains, to name a few, in a non-invasive and contactless way, with respect to monitoring; and using comparatively safe and/or low energy electromagnetic radiation, such as radio waves. Negligible-sized backscatter-tags with sensors are implanted in or attached to such orthodontic-elements. Such arrangements may permit monitoring of forces acting on teeth by various orthodontic-elements. Using backscatter imaging technology, the structural integrity and other states of the orthodontic-elements may be monitored; which may allow non-invasive and contactless detection of problems such as cracking, bending, excessive pressure, improper temperature, and/or the like. Additionally, initially unknown locations of the implanted negligible-sized backscatter-tags with sensors may be readily determined upon a given scanning (reading) session; and thus mapped to provide an effective image of the orthodontic-elements.
