ABSTRACT:
An applicating device and method of cosmetic bonding and veneering of teeth with composite dental material which includes a disposable syringe tip defining a reservoir for containing a predetermined amount of composite dental material and having connected thereto a discharge end portion which narrows to a rectangularly shaped discharge orifice having a width of approximately 0.5 mm and a length of approximately 4 to 6 mm. A piston or plug seals the end of the reservoir portion and which piston is displaceably disposed in the reservoir portion. The discharge orifice is provided with a sealing cap when not in use. The method of bonding and veneering a dental material on a tooth includes the step of expressing a flat thin ribbon veneer of composite material directly onto the tooth. The composite material is formed in a thin uniform flat strip of not more than 0.5 mm in thickness and approximately 4 to 6 mm. in width by expressing it through the discharge opening of a syringe tip. Depending upon the nature of the composite material, the tip may be of varying degrees of opacity from clear to black.
