Ceramill Sintron

ceramill sintron®

CoCr dry mill – easy as wax

Ceramill Sintron revolutionises CNC-based dry processing of non-precious metal restorations using desktop milling machines in-house in the laboratory. The wax-like texture of Ceramill Sintron allows the material to be dry milled effortlessly. During the subsequent sintering process under shielding gas atmosphere the frameworks achieve their final material properties – a CoCr unit with very homogeneous material structure. Any conventional CrCo framework porcelain can then be used for veneering. Ceramill Sintron was developed in collaboration with the Fraunhofer IFAM Dresden, Germany.

Indications

  • Crowns & Bridges, anatomically reduced & fully anatomical
  • Telescope
  • Multi-unit, screw-retained restorations on titanium
  • Custom abutments on titanium bases
  • Anatomically reduced and fully anatomical crown and bridge frameworks in the anterior and posterior region

Your benefits

  • Effortless dry milling and minimum cutter wear thanks to wax-like texture
  • Comfortable handling due to easy reworking and fi nishing of the milled framework in the green state
  • Maximum process reliability thanks to homogeneous, distortion-free frameworks
  • Excellent strength values, bonding strength and biocompatibility
