Syringe delivery system for dispensing a dental composite or other highly viscous material

A syringe delivery system for dispensing a viscous material through a syringe opening comprising:

• a syringe barrel having a delivery opening;
• a plunger including a threaded shaft that threadably engages said syringe barrel for selective dispensing of a viscous material through the delivery opening;
• and
• a plunger gripping member in gripping communication with said plunger that includes a sheath that covers said threaded shaft of said plunger so as to shield said plunger beneath the sheath;
• wherein said sheath provides a sealed environment for said threaded shaft so as to prevent entrance or contamination by foreign matter.

A method of using a syringe delivery system comprising:

• providing a syringe delivery system comprising:
• a syringe barrel having a delivery opening;
• a plunger including a threaded shaft that threadably engages said syringe barrel for selective dispensing of a viscous material through the delivery opening;
• and
• a plunger gripping member in gripping communication with said plunger that includes a sheath that covers said threaded shaft of said plunger so as to hide said plunger beneath the sheath;
• wherein said sheath provides a sealed environment for said threaded shaft so as to prevent entrance or contamination by foreign matter;
• manipulating the syringe barrel of said syringe delivery system so as to selectively dispense a viscous material through the delivery opening of said syringe delivery system;
• and
• cleaning the syringe barrel and sheath of syringe delivery system.
