Acetal partial denture is an ideal prosthetic solution for patients missing one or several teeth. Utilizing an Acetal framework, this type of denture offers superior durability, excellent aesthetics, and outstanding comfort. The Acetal framework can be combined with either Acrylic or Flexible denture bases, providing design versatility while optimizing both strength and aesthetics.
