[EP-23] The use of milled acetal in removable partial denture framework - a case report
[Abstract]
[Introduction]
Advances in digital manufacturing has significantly revolutionised the field of dental materials, providing clinicians and technicians with good precision, efficiency and customisation over large spectrum of metal-free options. This case report aims to describe the clinical procedure of fabricating a highly crystalline acetal copolymer resin, and to examine and evaluate its use as a material for removable partial denture frameworks.
[Case Summary and Treatment Details]
The report presents the treatment of a 60-year-old female patient who presented with aesthetics and functional concerns regarding her removable partial cobalt-chromium denture. Following master impressions made with conventional impression techniques, the master casts were scanned, and digitally designed, and the acetal copolymer resin (Zirlux Acetal) removable framework was milled, which was tested to ensure the accuracy of fit before final heat-processing with acrylic teeth.
[Progress and Discussion]
The clinical outcome demonstrated that the acetal base polymer was a viable option for removable partial frameworks that provide satisfactory retention, resistance, and better aesthetics. Despite the potential advantages of adopting a metal-free digital workflow in the fabrication of dentures, this presentation will discuss other clinical considerations like accuracy and precision of fit, treatment efficiency, patient’s subjective feedback, and other production nuances.
