Abstract

A lightweight, small footprint, composite extraction pen, for the delivery of dental filling composite from commercially available composite filled carpules. An electric linear actuator is housed in a slender, pen-like housing configured to accept, constrain and allow the rotational positioning of commercially available composite filled carpules. The carpules are contained within an adaptor that connects to the body of the pen. The linear actuator extends and retracts a piston through a bore in the carpule so as to exert pressure on the composite contained therein. The pen provides precise composite delivery while maintaining a highly visible dental environment.
