Applicator for dental material |
摘要 |
For free-hand use by a dentist, there is provided a cylinder containing tooth filling material urged out of the cylinder by spring pressure, sometimes augmented by thumb pressure against the end of a piston rod in the cylinder. Flow of the material out of the cylinder through a removable and replaceable flexible curved nozzle is under control of a valve located to be readily manipulated between open and closed positions by the same hand of the dentist. Preferably the filling material is in a discrete capsule containing enough filling material for several teeth and easily placed in and removed from the cylinder.
