    Abstract: An adjustable orthodontic band conforms around teeth of varied sizes. The band may be elastic or a superelastic alloy, and elastically expands under force to fit different teeth. Or the band has shape memory, e.g. shape memory metal alloy, with variable circumference under applied energy such as heat. The band may be solid heat shrink or elastomeric polymer, or metal alloy. Or, interconnected struts are separated by voids that may receive cement or are covered with elastomer. Adjustability may vary along the band. A kit of adjustable bands has varied adjustable size ranges, and may include no more than about 8 or fewer bands together covering an overall range of up to 30% or more difference in circumference. One band having at least a 30% range of adjustable circumference also may be provided for each tooth type. The adjustable bands are pre-coated with cement, and are pre-packaged in a UV and moisture protective container. Estimated size is all that is required to choose the correct band for most teeth.

    Abstract: An improved dental appliance system, and methods for using and fabricating the improved appliance, including a polymeric overlay or shell having a teeth-receiving cavity formed therein. The dental appliance having the necessary stiffness or strength to firmly secure the appliance on the teeth and provide controlled forces required for repositioning the teeth, until such time as removal of the appliance is desired. The appliance may be configured for use with a removal mechanism. The removal mechanism provides for selective release of the appliance from the teeth as the removal mechanism undergoes a state change stimulated by an environmental stimulus or environmental switch.

    Abstract: A superelastic endodontic instrument, such as a file, is formed by grinding a superelastic wire to form a file preform or blank, and rotating a first end of the blank while preventing rotation of a second end of the blank. The file blank is maintained in the austenite phase at least until twisted to form a stress induced martensite which is plastically deformed by the twisting. A heat treatment step may be performed prior to twisting, during twisting or after twisting of the preform. The file blank may be heated by electrical heating methods or by submerging the blank in a heated liquid.

    Abstract: The present invention is a dental implant inserted into the jaw bone for anchoring an artificial tooth in the bone. It has been designed to overcome the difficulties and complexities of prior art implants. The inventive implant consists of three simple components: An elongate body which has an neck portion and a root portion; an abutment which is mounted to the neck portion of the body and which receives the temporary or permanent replacement tooth; and a screw which secures the abutment to the body. The root portion of the body consists of multiple legs and is formed from a shape memory alloy. Use of shape memory alloy allows the root portion to assume a closed, elongate shape at cool temperatures and to assume an open, fanned shape at temperatures typical of the human body. The inventive implant is maintained at cool temperatures until and during insertion into the body allowing an easy and non-traumatic placement of the implant. Once in place, the implant warms to body temperature and self expands to anchor itself within surgical site. A method for using this self-expanding dental implant is also provided.

    Abstract: A ligature for an orthodontic appliance comprising a coil spring hoop of helically wound metal strip or wire or a wave spring hoop of wave wound metal strip or wire, preferably of shape memory metal. Such a metal ligature is simpler and more convenient to use than wire ties and has a life considerably longer than the elastomeric ligatures currently in use; because of this extended life they can be permanently attached to a bracket body to provide a self-ligating bracket. A coil wound ligature has the form of a hoop and is attached to the bracket body via a U-shaped core member threaded through part of the hoop and having its ends fastened to the bracket body. The ligature may have the form of a loop having its ends inserted in respective bores in the bracket body. The ligature may comprise an attachment part by which it is attached to the bracket body and a loop retainer part engageable over a bracket tie wing, the attachment and retainer parts being connected together by two mesially-distally spaced wave wound spring parts.

    Abstract: A tooth-fixing member of a shape memory alloy including two pairs of fixing fingers formed on both sides of a band base for engaging teeth, the pair of fixing fingers being processed to open in parent phase and close in martensite phase. Tooth fixing procedure includes the steps of: forming a cavity in each of plural target teeth; inserting each pair of fixing fingers of the tooth-fixing member in martensite phase into the cavity; and heating the tooth-fixing member to the parent phase to open the fixing fingers so as to fix the teeth together. The tooth-fixing member applicable to various dental treatments, which include: fixation of teeth which are loose due to periodontal diseases like pyorrhea alveolaris; fixation of teeth to ensure a space for a tooth to erupt; fixation of a tooth which is extruding abnormally; fixation of a transplanted tooth; and correction of slanting teeth.
