System for taking an impression in the patient's mouth of an implant stump comprises perforated tube that goes over stump end and piston that fits into its open end

摘要

The system consists of a tube (7) with one or more vents (13) that fits over a stump (5) to receive a prosthetic tooth that is inserted in a jawbone implant (2). The lower end (8) of the tube is shaped to fit against the base (6) of the stump portion that projects from the implant, and its open upper end is made to receive a plug in the form of a piston (10) that compresses the material (14) used to take the impression, while surplus material is squeezed out through the vents.
