Modified hygroscopic gold casting technique.

B T Cecconi, K Asgar

The Journal of Prosthetic Dentistry

|February 1, 1975

Summary

This summary is machine-generated.

A modified hygroscopic gold casting technique uses a dual-wax pattern and controlled water addition to the investment. This method enhances investment expansion for improved gold casting results, with excellent clinical success since 1970.
