Title:
IMPACTOR AND PASTE FEEDER
Document Type and Number:
WIPO Patent Application WO2004008982
Kind Code:
A3
Abstract:
An impactor (10) for safely, efficiently, and effectively placing mercury-free dental restorations in a cavity of a patient's tooth, the impactor (10) having a housing (35), anvil (32), hammer (33), solenoid (31) or other transducer, end cap (49), source of restoration paste, and paste feeder tube for condensing mercury-free paste in the cavity. The impactor (10) provides periodic impulses by activating the solenoid (31), causing the hammer (33) to strike the anvil (32). The anvil (32) is forced into contact with the paste, thereby condensing the paste into a high-density metal or other material suitable for dental restoration. Also disclosed is a solenoid (31) or other transducer having a "T" shaped hammer (33) which strikes an anvil (32). The solenoid (31) or other transducer can be used to compact or strike any surface.
