The resins and removable partial dentures are one of the most common methods to fill dental cavities and treat the partial edentulism.

Through the years, the experts have used many materials, and combinations of them, to improve the resistance and flexibility of the prosthetic material.

What are the Acrylic/Acetal Dentures?

The Acrylic/Acetal dentures (also called poly-methylmethacrylate or PMMA and polyoxymethylene or POM) are defined by the experts of the University of Medicine and Pharmacy Timisoara as a synthetically obtained material that can be modelled or injected in many ways to fill dental cavities and other abnormal spaces, or to create dental replacements.

How are the Acrylic/Acetal Dentures created?

To create the acrylic/acetal dentures, the specialists can use the material in two forms, as prepackaged cartridges or in a granular form that will be manipulated to be used as an injectable material.

The thermoplastic grains of acrylic/acetal are heated (it melts at temperatures between 200 and 250°) to plasticize the resin and later fill the mold with the form that is needed (the acrylic/acetal material is injected under pressure).

Finally, the acrylic/acetal dentures are combined with metal-free ackers circular clasps, which act as support and help to stabilize the dental prosthesis in its place when the patient puts it on.

Likewise, as this material is so flexible, it is able to accommodate into the patient’s mouth (even in the most complicated cases) to provide an excellent stability while used. The acrylic/acetal is also considered an ideal material to create a lot of dental prostheses and parts of them, including the pre-formed clasps for partial dentures, provisional bridges, partial denture frameworks, stress-absorbing components of the dental implant systems, single pressed unilateral partial dentures, orthodontic appliances, artificial teeth for removable dentures, among others.

Another important advantage of acrylic/acetal is the great biocompatibility of this material, which makes it an excellent material to be used in the mouth and teeth without experiencing adverse reactions (it is non-allergic and non-toxic).
