CAD CAM System for dental ceramic zirconia blocks
Mar 27, 2018| CAD CAM System for dental ceramic zirconia blocks
A Precision Solution for Modern Dental Restoration
The Dental Zirconia CAD/CAM System is an advanced digital solution that streamlines the design, milling, and production of zirconia dental restorations with high precision and efficiency. It integrates cutting-edge hardware and software to meet the demanding clinical and aesthetic requirements of today's dentistry.
System Composition
A typical zirconia CAD/CAM system includes:
3D Scanning Device: Captures accurate digital impressions
CAD Design Software: Creates detailed 3D models of restorations
Milling Machine: Precisely mills zirconia discs based on digital designs
Sintering Furnace: Densifies and strengthens the milled restorations
Working Principle
Digital Scanning: Captures the patient's oral structure using a 3D scanner.
Design Phase: Restoration shape, size, and fit are modeled via CAD software.
Milling Process: The CAM module guides the milling unit to carve the zirconia disc.
Sintering: The milled zirconia is fired in a high-temperature furnace to finalize strength and translucency.

Sintering
It is not hard to imagine that the digital scanner laid the foundation of the high-precision since the making of the denture. The powerful software can automatic recognize and process the denture related data.When the computer locks the basic data that ensured the precision of the denture,those 3D images can be moved and revised freely,which offer chances to the dental technicians for the personal processing, and can satisfy the needs of the patients. When the design is finished, the milling machine turn the cubic zirconia blocks into crystal teeth. The multi-axis designing reduces the deviation to less than 15mm, which ensures the original form of the teeth precisely and avoid the the loss of precision and strength that was caused by the manual grinding after the milling to the largest extent.The ziconia material has been protected during the whole milling process and avoid the defect that even can be remedied by post-production . Sinistering and crystallization are the final process during the processing of the zirconia blocks. The precisely temperature controlled crystallization furnace ensure the shrinkage of the material is in conformity with the shrinkage factor.
High accuracy processing equipment and procedure make the zirconia block denture is fitted evenly and closely to the natural teeth.The models that are showed by the manufacturers have the same quality of the denture in the patients' mouth.Because the processing equipment which is controlled by the computer will not varies from person to person.The gap which is less than 100um avoid the pigmentation and the invasion of the bacterial infection, which let us do not have to damage the gingiva in order to make our teeth look more beautiful in the exceptional cases .
