AI Technical Summary

Benefits of technology

The present invention provides an appliance for orthodontic treatment with a ready base that can be easily mounted on a patient's bone. The base has a cured layer and an uncured layer of polymer resin that enhances the bonding strength and makes the removal of the base easy. The uncured layer is cured when the appliance is mounted on the patient's tooth to form an integral base for the appliance. The base is transparent or translucent and includes a cured layer that serves to wick or transmit curing light energy over the entire layer of uncured resin to achieve better bonding and curing of the uncured layer.

Problems solved by technology

Secondly, an uncured layer of substantially the same polymer resin would be applied to the cured layer and the appliance with this bilayer base would be suitably packaged and ship ed to an orthodontic customer, who would mount the bracket on a tooth, after suitably preparing the tooth, and thereafter cure or polymerize the uncured layer of resin to effect attachment of the bracket to a tooth.

Embodiment Construction

[0021]Referring now to the drawings, and particularly to FIGS. 1 to 4, an orthodontic bracket 10 is shown in mounted position on a tooth 11 in FIGS. 1 and 4 to illustrate the invention. It will be appreciated that the bracket 10 includes a bracket body 14 and a base 16.

[0022]While the bracket body 14 illustrates a bracket of a type that is sold by TP Orthodontics, Inc. of LaPorte, Ind., it will be appreciated with respect to the invention the bracket body may be of any suitable type and of any suitable material. Moreover, the invention, being directed primarily to the base, can be used on any appliance that would be mounted on a tooth, including a bracket, a molar tube, or a lingual button, an implantable stem for a tooth implant, or other appliance desired to be bonded to a tooth or the jaw for purposes of dentally or orthodontically treating a patient. Thus, the appliance body 14 may be of any type that would be useful in treating the dentition of a patient, orthodontically or oth...

Abstract

A bilayer base for attaching appliances selected from the group consisting of a component of a dental appliance, an orthodontic appliance, or an orthopedic appliance to a bony part of the human body wherein the appliance part to be attached to the bony part of the body may be made of metal, ceramic, or plastic. The base permits the appliance to be ready for mounting and includes a cured layer of polymer resin mounted on the appliance and an uncured layer of substantially the same polymer resin over the cured layer which when cured becomes integral with the cured layer in attaching the appliance to a bony part of the body.

Description

[0001]This invention relates in general to a ready appliance for immediate attachment to a bony part of the human anatomy, and more particularly to an adhesive base on the appliance having a cured layer of plastic material attached to the appliance and an uncured layer of substantially the same material to be cured at the time of mounting the appliance on a bony part of the human anatomy.BACKGROUND OF THE INVENTION[0002]Heretofore, it has been known to provide prepasted orthodontic appliances (appliances having uncured adhesive on the mounting side) to orthodontists for immediate mounting on teeth, without requiring the orthodontist to apply adhesive, like the appliances disclosed in U.S. Pat. Nos. 4,204,325 and 4,978,007. Such prepasted orthodontic appliances include a body provided with an uncured layer of chemically curable or light-curable adhesive on the mounting side which when cured attaches and secures the appliance to a tooth. It is well known that this type of an orthodont...
