CAMselect for KaVo Everest - nickel-free cobalt chrome alloy
The premium alloy CAMselect
CAMselect is a nickel-free cobalt chrome alloy with excellent screening abilities, excellent bonding abilities and high biocompatibility. The premium material is refined with further materials to achieve an incomparable milling ability in the dental CAD/CAM world. Crown margins do not biologically react and therefore discolouring of the gum does not appear.
Clear advantages of CAMselect
- High mechanical strenght
- Low heat conductance
- Gracile design of the framework
- Abrasion bahaviour like enamel
- Silver and palladium free
- Very good milling ability
- Excellent screening abilities
- Thin margin design possible in the cervical margin area
- Excellent polishing ability
Biocompatible material quality
Like all KaVo materials CAMselect is also tested for its compatibility and biocompatibility and therefore certified.
