Zirlux Acetal Partials: Pros and Cons
Esthetic, durable, metal-free tooth borne removable partial dentures are made from Zirlux Acetal resin by CAD/CAM technology to exacting specifications for a precise fit. The patient will appreciate the comfort, the ease of wear, the lack of a metallic taste, and no thermal conductivity when drinking cold or hot beverages. Like its metal counterparts, denture teeth must be physically bonded to the resin framework with denture acrylic or a monomer-free acrylic substitute.
Taking Impressions for Resin-Based Zirlux Acetal Partials
The teeth, hard tissue, and surrounding soft tissue of both arches may be digitally scanned using a chairside scanner. Data files are electronically transferred to the dental lab for incorporation into the digital processing workflow.
In the absence of a chairside scanner or for complex cases that involve missing teeth in multiple quadrants, bite registrations and impressions taken in scannable impression trays are sent to the dental laboratory. The records are scanned by the laboratory technician using a three-dimensional scanner that literally takes hundreds of images of the physical records at all angles in all dimensions.
With either method, the collected data files are used to construct virtual articulated three-dimensional models of the patient’s dentition that can be rotated and viewed from any angle or any plane in space. This allows the partial to be designed via computer-aided design (CAD) and fabricated by computer-aided manufacturing (CAM).
Zirlux Acetal Color Choices
The millable copolymer material is available in VITA shades A1, A2, A3.5, B1, plus G2 (bleaching shade), and P1 (pink). These color choices allow for a wide range of color-matching options that work well in many situations and with different tooth configurations.
Zirlux Acetal Partials’ Average Lifespan
An appliance made from this resin can last up to 10 years, depending on parafunctional habits and patient care.
