Aluminum Denture Flask Cleaner

Dental Aluminum Denture Flask Cleaner

Features

1. A dental flask for denture-making is provided which includes a pair of threaded, longitudinally shiftable pins received in stepped, communicating bores in the anterior region of the primary,and closure sections of the flask to permit selective movement of the pins between a position precluding significant relative movement of the flask sections and a position permitting limited degrees of such movement.

2. The pins are shifted to their movement-blocking positions during all preliminary operations of the denture-making process, and thereafter moved to their recessed positions in order to ensure accurate reproduction of the denture model by compensating for the characteristic expansion and contraction of the denture material during hardening thereof.
