Acetal frameworks / tooth coloured clasps | Bremadent Dental Laboratory in London
Acetal is a polyoxymethylene semi-flexible, tooth coloured material that delivers high strength, durability and high resistance to wear. It's routinely used for partial denture frameworks and tooth coloured clasps due to it’s functional and aesthetical features which blend seamlessly with natural teeth. It's used as an alternative to acrylic and chrome dentures and is digitally CAD/CAM milled.
Technical features:
Acetal frameworks / tooth coloured clasps are milled via our in-house CAD/CAM milling machine from a digital IO scan or traditional impressions. The material is biocompatible and 100% monomer / metal free. It has a flexural strength of 90mpa and a moisture absorption of 0.22 wt%. It is used for partial denture frameworks, tooth coloured clasps, temporary crowns or single one tooth dentures with clasps as one unit.
Acetal exhibits exceptional a high tensile strength and is resistance to wear, abrasion, and fatigue, ensuring long-term durability. The material is dimensionally stable and maintains it’s shape when exposed to saliva and oral fluids. It has a low coefficient of friction, reducing the potential for irritation or damage to adjacent teeth and tissues. It also exhibits good wear resistance, ensuring that dental restorations maintain their integrity and functionality over an extended period.
Clinical features:
Acetal frameworks are easy to adapt too, lightweight, thin and semi-flexible which makes it comfortable to wear for the patient. They blend in naturally with the adjacent teeth whilst being held in securely and firmly by the tooth coloured clasps as part of the framework which is easily adjusted chair side if needed. They are easy to maintain and have a high resistance against staining due to it's chemical resistance against oral acids and other chemicals in the mouth. Please see images below:
