Zirlux Acetal Partial Dentures
Special Features of Zirlux Acetal
Zirlux Acetal Partial Frameworks are designed and milled from a void-free disk of copolymer using CAD/CAM technology for precise fit. Flexible partial dentures are tissue borne; Zirlux Acetal resin is different because it is semi-flexible. Its strength allows the manufactured framework to be supported by the existing dentition, much like a metal framework. Clasps are made from the same resin material. They have elastic memory and are designed to engage securely into the natural undercuts of abutment teeth for maximum hold.
When to choose Zirlux Acetal over other types of partial dentures
Zirlux Acetal is an ideal framework option for patients that are sensitive or allergic to free monomer used in denture acrylics. Esthetically-conscious patients will enjoy a partial that visually disappears in the mouth. Suitable for partial dentures, Nesbit partials, or as a transitional appliance during healing for implant cases.
Zirlux Acetal Material Properties
What is it made from? Zirlux Acetal is made from 99.9% pure polyoxymethylene (POM), a highly crystalline millable thermoplastic copolymer. Acetal resin properties include high tensile and flexural strength, fatigue resistance, low moisture absorption, and excellent dimensional stability.
Acetal has been successfully used in dentistry worldwide for more than 30 years in an injectable form. This material now comes in millable form which eliminates the problem of shrinkage during processing. Acetal resin cuts cleanly and quickly using either wet or dry milling methods.
How to Care for Zirlux Partials
After meals, rinse the appliance under cool, running water to remove any debris or food particles. Use a soft bristle denture brush with a denture paste or liquid antibacterial soap to clean the appliance.
Never use any abrasives such as toothpaste meant for use on enamel, powdered household cleanser, or a hard-bristled brush to clean the partial denture.
Can you add teeth to a Zirlux Acetal Partial?
As a Zirlux Acetal provider, Stomadent Dental Lab has the equipment and expertise necessary to quickly and easily make reasonable minor repairs and additions to the resin partial using genuine Zirlux materials.
Hybrid Partials: Zirlux Acetal Resin with Metal Frameworks
It is possible to combine Acetal resin elements with a Wironium or Titanium framework to create a hybrid partial that possesses the benefits and esthetic appeal of tooth-colored semi-flexible clasps with the added strength and rigidity of a metal framework. This option is particularly important in the case of free end or long span partials where partials made from flexible or semi-flexible materials don’t always function ideally during mastication.
