Abstract
A dental bracket having a non-adhering, moldable base, wherein the moldable base is conformed to the surface of the tooth to which it is to be adhered. A very thin layer of dental adhesive interposed between the moldable base and the tooth (by coating of any or both of the tooth and moldable base--preferably the tooth) effects full adherence of the bracket to the tooth. The base material is fully cured by normal curing methods such as by UV or other wavelength light activation. Use of a non-tacky, bondable plastic membrane (or coating or use of a thin inert interposition material which is non-tacky and bondable) bonded to the base material (and which is conformed with the molding of the base material), facilitates application of a bracket with an applicator. A bracket applicator and package suitable for use with the dental bracket of the present invention is also described.
