Claims6
In a dental implement for dispensing amalgam, said implement having a handle, a lever mounted on said implement, an amalgam carrier engaging the lever, a dispensing rod extending from one end of the handle, a portion of the dispensing rod cooperating with the amalgam carrier to dispense the amalgam, a spring having a rear end secured to the handle and a front end engaging the lever to maintain the carrier in a normally lowered position so that by operating the lever the amalgam carrier is raised and the dispensing rod extends beyond the amalgam carrier, thereby acting to discharge the amalgam, the improvement comprising:
- means extending from said dispensing rod for condensing the amalgam into the tooth cavity.
A dental implement for dispensing amalgam comprising in combination:
- a handle;
- a lever mounted on the dental implement;
- an amalgam carrier engaging said lever;
- a dispensing rod extending from one end of said handle, said dispensing rod having:
- a shank portion extending outwardly along the longitudinal axis of said one end of said handle, a transverse portion extending away from said longitudinal axis of said handle,
- an oblique portion oriented at an acute angle to said longitudinal axis of said handle, and
- a curved portion forming an arc connecting said transverse portion and said oblique portion;
- a spring having a rear end secured to said handle and a front end engaging said lever to maintain said amalgam carrier in a normally lowered position so that by operating said lever said amalgam carrier is raised and a segment of said oblique portion of said dispensing rod extends beyond said amalgam carrier, thereby acting to discharge the amalgam;
- and
- a plugger extending outwardly from said curved portion of said dispensing rod and forming an obtuse angle with said oblique portion so that after the amalgam is dispensed, the dental implement may be inverted to position said plugger in proximity to the tooth cavity for condensing the amalgam.
