Preimpression preparation for positive recovery of master casts.
A technique has been described to ensure positive recovery of a cast by using wax to enlarge teeth that have diastemata and teeth that are periodontally involved with bone loss. On removal of the wax, a void is created in the impression. Stone poured into the void will strengthen the involved teeth so that the cast will not fracture on removal from the impression.
