Abstract
The present invention provides a delivery syringe and a set of delivery syringes for flowable composite materials that overcome the difficulties associated with currently available composite delivery methods. Specifically, the present invention provides a flowable composite delivery syringe with a vibratory mechanism. The vibratory mechanism allows the composite material to contain a higher filler load and still have desirable flow characteristics. The higher filler load produces a stronger composite material with less shrinkage during the curing process. Additionally, the vibratory mechanism contained in the delivery syringe prevents air entrapment voids during the delivery of the composite material into the tooth cavity preparation.
Claims17
A set of flowable dental composite delivery syringes, each syringe having a connection site for a self contained vibration apparatus that can be easily moved from syringe to syringe within the set of composite delivery syringes, the vibration apparatus containing a vibration source, battery source, and on/off actuator, wherein the vibration source increases the flowability of the extruded flowable composite material and reduces air entrapment in the dispensed composite material.
A flowable dental composite delivery syringe, having a vibration apparatus that transfers vibration to the syringe tip and the dispensed flowable composite material as it enters a tooth cavity, wherein the vibration source increases the flowability of the extruded flowable composite material and reduces air entrapment in the dispensed composite material.
