Intelligent and Intuitive

Z4 uses different-sized tools.

• Automatic changer for 6 tools with haptic tool length detection and tool breakage monitoring
• 5 tool changer inserts (6 tools each) coded for different applications or materials
• Color-coded tool magazines

Cost Saving and Performance

• Widest choice of materials
• Flexibility in intraoral scanners
• Seamless workflow due to Z4’s integration with 3Shape™, DWOS Chairside™ and Exocad ChairsideCAD™
• Z4 doesn’t require additives as it purely operates with clear water
• Z4 can mill even titanium abutments due to its sturdy build.
• Produce your titanium implant abutments using prefab abutment blanks. For hybrid implant restorations such as a screw-retained crown or hybrid abutments, standard blocks can be used, as the Z4 drills the screw channel itself
• All blocks with the most commonly used CEREC® or universal mandrel can be loaded into the Z4

Smart. Silent. Sturdy 

• Z4 reminds you and gives detailed instructions on cleaning and maintenance
• Easy-cleaning coating
• The inside of the milling chamber is coated with non-stick paint that lets the water just drip off.
• Noise reduction. Silent mode is available.
• Extra thick layers of sound-absorbing foam around the milling chamber helps to reduce noise
• Massive machine bed of aluminum cast to minimize vibrations and distortions
• Finely balanced spindle
• State-of-the-art controller

Safe Operation

• Z4 checks if the right tool magazine is loaded
• It measures the blocks to ensure that the right size is being loaded
• One cannot open the mill during operation due to its patient protection lock mode
• A service camera is incorporated so that the service technicians can review the recorded video stream
