Pre-surgical planning for cranial and facial reconstruction includes preparing a computer generated jaw or skull model for determining a locational position for a dental implant, a surgical bone implant to repair missing bone in the cranium, install ear prostheses, and/or install nose prostheses. The computer generated jaw or skull model is made from medical imagery and computer aided design. A surgical guide is prepared with oversize holes in registration with analogs for the dental or surgical bone implants to be inserted in the jaw or cranial skull model. The surgical guide is fitted atop each analog, and bonded to the jaw or skull model at a predetermined angle of the analog in the jaw or skull. The surgical guide is removed and attached to the jaw or skull of a patient for accurate drilling for insertion of the implants into the jaw or skull of the patient.

A retainerless orthodontic dental implant system for positioning the mandible forward relative to the maxilla and for facilitating optimal airflow during sleep and a method of using such a system.

A method of increasing movement of a tooth in a jaw having at least one tooth with an orthodontic brace thereon includes: (1) holding a handle of a device, the device having an elongate member extending from the handle and a screw tip at a distal end of the elongate member; (2) moving a sleeve along the elongate member to set a length of exposed screw tip; (3) locking the sleeve in place relative to the screw tip; (4) drilling a hole with the screw tip through a cortical bone of a jaw to increase movement of the tooth; and (5) stopping the drilling when the length of exposed screw tip has penetrated the jaw.

An orthodontic structure includes a body where at least one connecting hole is formed, a fastening part disposed on the body and fastened to an implant, and at least one traction assembly connected to the body. The traction assembly includes an orthodontic table and an adjustment part extending outwards from the orthodontic table to engage the connecting hole. The orthodontic table has at least one locking recess capable of holding a metal wire in place. The orthodontic structure is connected to the implant which is embedded in an alveolar bone in advance to provide a requisite anchorage effect required by orthodontics. Thus, the implant treatment and the orthodontic treatment can be concurrently executed to shorten the treatment time for straightening teeth and attain good implanting and straightening effects.

A method is provided including shaping a thermoplastic material on a dental arch of a subject and utilizing the shaped thermoplastic material to facilitate inserting of a steerable implantable neural stimulator into a greater palatine foramen of the subject. The method further includes advancing the stimulator through a greater palatine canal of the subject to a sphenopalatine ganglion (SPG) of the subject. Other applications are also described.

A hybrid temporary anchorage device implant system and method of use is disclosed. A temporary anchorage device (TAD) implant includes an external hex head, a cupped inner portion, a threaded core, a platform, and an implant portion. A first abutment is installed on the implant portion. The first abutment may include a graduated portion, a screw-retained healing collar, and a threaded portion. A second abutment may be installed over the first abutment. The second abutment may include a graduated head, a bulbous base, and an inner canal.

An orthodontic structure includes a body where at least one connecting hole is formed, a fastening part disposed on the body and fastened to an implant, and at least one traction assembly connected to the body. The traction assembly includes an orthodontic table and an adjustment part extending outwards from the orthodontic table to engage the connecting hole. The orthodontic table has at least one locking recess capable of holding a metal wire in place. The orthodontic structure is connected to the implant which is embedded in an alveolar bone in advance to provide a requisite anchorage effect required by orthodontics. Thus, the implant treatment and the orthodontic treatment can be concurrently executed to shorten the treatment time for straightening teeth and attain good implanting and straightening effects.

An orthodontic appliance can easily achieve and ensure movement of correction target tooth row in a desired direction and achieve highly predictable treatment is provided while anchorage is satisfactorily ensured. A correction device includes a grip member formed to fit to an inner shape of an oral cavity of a patient so as to grip and cover a tooth row, gum parts, and alveolar bone parts of the patient. The correction device includes a first piece 20 covering an area extending from a crown part to a periphery of a cervical part of a correction target tooth and a second piece included in the grip member. The correction device further includes a force applying member 30 provided to connect the first piece 20 to the second piece 10 and configured to move the correction target tooth in a desired direction.

A temporary anchor device includes at least one screw mechanism and an external plate. The at least one screw mechanism includes a skeletal screw having a threaded portion configured to drill into jaw bone of a patient, a smooth portion configured to sit within gums of the patient, and a proximal portion configured to extend external to the gums. The at least one screw mechanism further includes an attachment mechanism configured to attach to the proximal portion of the skeletal screw. The external plate is configured to be locked between the skeletal screw and the attachment mechanism to anchor the external plate external to the gums.

The present invention provides a dental member, which has a reduced size, and thus prevents damages to tooth roots upon implantation, has high strength and low elasticity, and is excellent in engraftment stability after implantation. The dental member is produced with an amorphous alloy having a composition represented by formula: Zr.sub.aNi.sub.bCu.sub.cAl.sub.d [wherein a ranges from 60 to 75 at. %, b ranges from 11 to 30 at. %, c ranges from 1 to 16 at. %, and d ranges from 5 to 20 at. %] and is used as an orthodontic anchor screw wherein the screw part has a core diameter of 0.5-1.0 mm or a length of 2-5 mm, a one-piece-type dental implant wherein the screw part has the largest diameter of 0.5-2.9 mm and a length of 2-13.4 mm, or a two-piece-type dental implant wherein the screw part has the largest diameter of 0.5-2.9 mm and a length of 2-5.9 mm.
