The best part about being able to design the Acetal, metal, and Titanium frameworks, is the fact that we produce all of these frames in-house. Whether we are 3D-printing Wironium frames and casting them, or we are designing our Acetal frames or Titanium frames and milling them, all cases are totally handled in-house.
With the design for the Acetal framework, the clasp is much thicker where it connects to the minor connector. It becomes thinner and narrower as it extends toward the mesial part of the tooth. These Acetal frames they are a great substitute for patients that do not want to wear metal partials but prefer to have a restoration that is more esthetically pleasing and flexible than rigid metal or titanium.
The main difference between metal frameworks, such as Wironium and Titanium, and these flexible Acetal frameworks are the frameworks can be tooth-colored so they will match the patient’s teeth and at the same time be flexible in the patient’s mouth.
