Acetal Resin (Dental 'D')

Dental 'D' clasp detail

Acetal resin (Dental 'D') is highly resistant to abrasion and possesses excellent tensile and shock strength. Possessing high elastic memory and low thermal conductivity, it is non-toxic and non-allergenic, making it a good substitute for acrylic resins and metals in many prosthetic applications.

Our acetal resin is made in all of the full classic Vita shades and three shades of pink for gum restoration work. A variety of products can be manufactured from this material, but we mainly use it for aesthetic clasps and space maintainers. Clasps can be injected directly, either onto the chrome base or into an acrylic denture, and new clasps can be added to existing dentures to improve their appearance. Creative Chrome manufactures the following acetal resin products.

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.

Figure 1: class 3 jaw relationship, left-hand side

This case was first presented to Steve in 1993. The patient has a class 3 bite, as seen in figs 1,2 and 3, and wanted a denture made to present a class 1 appearance. Previous attempts had failed because the anterior teeth needed to be set so far forward of the ridge that they destabilised the whole appliance even with clasps. The challenge was to manufacture an upper denture that would be at once cosmetically pleasing, retentive and stable.
