Mold compound ejection tip for dentistry

An intra-oral molding compound ejection tip is provided to provide a substantially uniform expanding solid angle of the mixed molding compound upon molding compound ejection. A prior art intra-oral tip typically includes an ejection orifice defined about an axis parallel to the direction of mold compound ejection. In a preferred embodiment, two cuts are placed in the tip at right angles to one another within the plane of the normal axis of molding compound ejection. Each of these cuts is sized with respect to the ejection orifice to produce a uniformly expanding solid angle of the ejected molding compound. This uniformly expanding solid angle of the ejected molding compound has the property of having higher normal incidence to both preparation and margin to the preparation in teeth having dental surgery.
