Gold castings

Gold is used extensively in many areas of dentistry, including full and partial removable dentures. Although expensive, gold has some advantages over cobalt chrome due to a lower value of modulus of elasticity and greater ductility. This gives clasps greater flexibility, allowing them to engage deeper undercuts with less likelihood of fracture. Gold also makes an ideal alternative to Cobalt or Nickel chrome for patients with allergies to those alloys.

We have found Argenco 60S from the Argen Corporation to be an excellent alloy for our requirements and use it for all of our gold castings.

We are happy to design cases for clients if preferred, but a downloadable design sheet is provided on this site for the convenience of those who wish to do this for themselves.

Double hinged sectional denture

Double hinge sectional denture framework, open

This case required a small unilateral denture to replace the patient's upper right 5 and 6. It was decided to use a two-part or sectional technique to ensure positive retention. There are numerous types of two-part denture designs, but this one may be unique to Creative Chrome, having been devised by Steve to fully engage all of the available undercuts when locked together with a P.W bolt (figs 1 & 2).
