Abstract

Example embodiments of the present invention include hot melt dental adhesive materials that can create a reversible bond. In addition, example embodiments of the present invention include hot melt dental impression materials that can be used to accurately and efficiently obtain a dental impression. Moreover, example embodiments of the invention include devices and methods for use with the hot melt dental adhesive materials and the hot melt dental impression materials disclosed herein. The hot melt dental adhesive materials and the hot melt dental impression materials can provide dental professionals with dental materials that are more effective, efficient, and easier to use when compared to conventional dental adhesive materials and conventional dental impression materials.

First claim

What is claimed is:

1. An orthodontic bracket, comprising:
a base portion made of a translucent material;
an extended portion extending away from a first side of the base portion;
a weak adhesion layer positioned on the extended portion, wherein the weak adhesion layer is at least semi-translucent to radiant energy;
a release liner positioned on the weak adhesion layer; and
a dental adhesive layer located on a second side of the base portion, wherein the first side and the second side are on opposite sides of the base portion; and
wherein the dental adhesive layer is configured to become molten in response to a supply of radiant energy and to form a bond between the orthodontic bracket and a tooth upon cooling.

2. The orthodontic bracket recited in claim 1 , wherein the dental adhesive layer comprises a thermoplastic component that has a first solid state and a second liquid state and is capable of changing from the first solid state to the second liquid state with an increase in temperature of the dental adhesive layer.

3. The orthodontic bracket recited in claim 2 , wherein the dental adhesive layer further comprises a radiant energy absorbing composition.

4. The orthodontic bracket recited in claim 1 , wherein the extended portion is made of a material that is at least semi-translucent to radiant energy.

5. The orthodontic bracket recited in claim 4 , wherein the second side of the base portion includes a surface texture that interfaces with the dental adhesive layer.

6. The orthodontic bracket recited in claim 1 , wherein the weak adhesion layer is made from a silicon oil polymer.
