Abstract

A device adapted to facilitate retention and release of a dental laminate includes an elongated main body having a channel extending through it, a resilient element connected to a first end of the main body for contact with the dental laminate, a connector disposed at a second end of the main body adapted to communicate the channel with vacuum suction, and a particularly configured valve body. The valve body includes a passage defined therein that is selectively rotatable between increased and decreased alignments with the main body channel to permit variable fluid flow through the channel as well as to essentially cut off fluid flow through the channel when desired. A bearing assembly is also disposed between an extension of the connector and a proximal portion of the elongated main body, thereby permitting essentially stress-free rotational movement between the connector and the main body.
