Abstract
The invention is directed to a composition that safely removes a cured dental cement or resin from metal brackets, metal braces, and enamel surfaces of teeth. It contains eugenol, isoeugenol, methyl-eugenol or an isomer thereof. A method for removing orthodontic fixtures adhered with a dental cement or resin to the enamel surfaces of teeth from these surfaces by contacting the dental cement or resin with a composition containing eugenol.
Claims10
A method for removing a dental appliance or dental prosthetic bound to a tooth or teeth via a dental resin, comprising:
- contacting the dental resin with a gel comprising eugenol, at least one polysorbate surfactant and at least one crosslinked acrylic acid polymer gelling agent, for a time sufficient to reduce a Vickers hardness of the dental resin to a value of no more than 70, and
- removing the dental appliance or dental prosthetic from the tooth or teeth.
A method for debonding a metal bracket, a dental appliance or dental prosthetic from a tooth or teeth comprising:
- filling a tray with a composition comprising eugenol,
- wherein the composition has a pH ranging from 6.0 to 8.0 and further comprises:
- a crosslinked acrylic acid polymer, and
- at least one polysorbate;
- fitting the tray over the tooth or teeth that are bonded to the metal bracket, dental appliance, or dental prosthetic for a time sufficient to reduce a Vickers hardness of a dental resin binding the metal bracket, dental appliance or dental prosthetic to the teeth to a value of no more than 70, and
- debonding the metal bracket, a dental appliance, or a dental prosthetic from the teeth.
