A dental composite is disclosed which is made of a light curable material containing filler particles suspended in the light curable material. The filler particles are formed from material that has been previously cured and then reduced in size, preferably by grinding, to a predetermined range of particle sizes.
A dental impression tray having a pair of spaced and outwardly flared sidewalls with a layer of material, such as gauze, netting, plastic or the like, or a rigid material, extending perpendicularly between the sidewalls. The sidewalls, furthermore, are dimensioned to extend substantially a one-half arch of a dental occlusion. The layer of material, however, extends outwardly from one end of the sidewalls so that the layer extends substantially a three-quarters of an arch of a dental occlusion. The dental impression tray is easily convertible between a one-half arch and a three-quarters arch of a dental occlusion by selectively removing the outwardly extending portion of the layer material. Additionally, a frame connects the sidewalls together while a notch in the frame enables the sidewalls to deflect upon occlusion and remain in a deflected position. Optionally, the sidewalls are eliminated.
Calcified Tissue Facing Preparation Containing An Antimicrobial Agent
The present invention provides a calcified tissue facing preparation characterized by having a polymerizable resin, and an antimicrobial agent of formula (I) where R is a hydrocarbon radical having between 1 and 16 carbon atoms, n is an integer between 1 and 8 inclusive and X is a halogen atom selected from fluorine, chlorine or bromine. It is appreciated that R includes unsaturated hydrocarbon radicals, as well as heteroatom containing radicals. Preferably, the molecule of formula (I) is associated with an adduct species. A solvent and the complementary spectrum antimicrobial benzalkonium chloride are also optionally added. An antimicrobial oral rinse excluding the polymerizable resin contains at least 0. 2% by weight of the antimicrobial agent.
Dental Bonding Formulation Complexing Calcified Deposits Associated With A Dentinal Tubule Opening
A dental bonding formulation provides a single application step in which a chelating agent present within the formulation is capable of complexing ions present in a dentinal tubule calcified deposit. The formulation has a pH of between 1. 2 and 4 to promote complexation without inducing excessive dentin etch. A curable resin is also present in the formulation to seal the underlying dentin surface.
A mouth guard having a tray with a trough dimensioned to receive at least the front two incisors. Impression material is disposed within the trough for creating a dental impression of the wearer's teeth. The tray further includes a stiffening element which concentrates the force transmission through the tray created by occlusion to an area between the upper and lower front incisors.
A mouth guard for a human adult which minimizes or eliminates teeth grinding. The mouth guard includes a tray having an arcuate trough opening at each end and dimensioned to receive at least the bicuspids of the human adult. The tray is constructed of a rigid plastic material. A dental impression material is disposed in the tray so that a portion of the impression material extends outwardly from each end of the tray by an amount sufficient to cover the canines or first bicuspids of the human adult when the tray is positioned over the bicuspids.
The present invention provides a calcified tissue facing preparation characterized by having a polymerizable resin, and an antimicrobial agent of the formula:
where Ris a hydrocarbon radical having between 1 and 16 carbon atoms, n is an integer between 1 and 8 inclusive and X is a halogen atom selected from fluorine, chlorine or bromine. It is appreciated that Rincludes unsaturated hydrocarbon radicals, as well as heteroatom containing radicals. Preferably, the molecule of Formula (I) is associated with an adduct species. At least one of glutaraldehyde or a chelating agent are added to enhance the preparation characteristics.
