Acetal for bite splints

WallaBC Acrtal Splint FLEX blanks are made of a thermoplastic copolymer based on a medical-grade PETG. The material is characterized by high flexibility and simultaneously high impact strength. Free of toxic and allergenic substances, it is ideal for patients with intolerances. Using CAD/CAM technology, you will achieve a perfect fit with no re-machining.

Benefits:

  •  Biocompatible – medical thermoplastic

  •  High level of flexibility

  •  Good polishing properties

  •  Possible to bond to conventional polymers (with a bonder)

  •  Bisphenol A and monomer-free

    Milling Attention

    The shoulder shall not be prepared in the area of corner and sharp edge. The shoulder shall be prepared in the shape of a round inner edge or inclined surface.

    The space of 1mm is required to be reserved for the preparation of the cutting edge, so as to ensure that the PMMA block can achieve the ideal grinding effect in the process of CAD / CAM. The preparation of the cutting edge should be at the enamel layer, and avoid the preparation at the point or area of stress concentration.

    Scope of Application

    • Invisible clear-transparent frameworks

    • Full, partial and implant supported dentures

    • Night guards

    • Clasps and other dental appliances processed by CAD/CAM milling machines for light weight, aesthetic non-metallic restorations.

    Highlights

    • More precision due to no injection heating or cooling, which avoids any expansion or shrinkage

    • Low moisture absorption and fatigue resistance

    • No thermal conductivity

    • Clasp on teeth instead of tissue.

    • More esthetically pleasing tooth colored clasp
