Abstract
A dental tool for use in photo-cured filling processes. The dental tool includes a tool tip formed from a material that allows the transmission of ultraviolet and visible light wavelengths through the tool tip without significant distortion or reflection. The material is also relatively high strength so not to shatter or break during use. The fill material will also not adhere to the tool. The material of a preferred embodiment is sapphire. The tool is able to continue to compact and shape the fill material while the composite polymer fill material is undergoing photo-curing. The light beam used for photo-curing is able to safely pass through the tool without the risk of damage to the surrounding tissue from reflection or distortion of the light beam.
Claims19
A dental tool for use in filling cavities, said tool comprising:
- a tool tip for manipulating fill material within a dental cavity;
- said tool tip formed from a material that transmits wavelengths between two hundred to seven hundred sixty nm without significant distortion.
A dental tool for use in filling cavities, said tool comprising:
- a tool tip for manipulating fill material within a dental cavity;
- and
- said tool tip formed from a material that allows wavelengths between two hundred to seven hundred sixty nm to be transmitted through said tool tip without significant distortion and a tensile strength between about two hundred seventy-five to four hundred MPa.
A dental tool for use in filling cavities, said tool comprising:
- a tool tip for manipulating fill material within a dental cavity;
- and
- said tool tip formed from sapphire so that wavelengths between two hundred to seven hundred sixty nm are able to be transmitted through said tool tip without significant distortion, a tensile strength between about two hundred seventy-five to four hundred MPa and the ability to easily shed fill material.
