With emerging technological advances, application of three-dimensional digitized data allows the clinician to have a surgical guide and a final prosthesis developed using computer-aided design/computer-aided manufacturing (CAD/CAM) technology. These approaches require a sophisticated surgical technique and may need further refinement to ensure the proper fit of the prosthesis.
Computer aided design(CAD) and computer aided manufacturing(CAM) are the most advanced fusion of technology,science and art . In simplified terms the computer programmed for recording the defect and then mills a block of zirconia to the exacting measurements.
ADVANTAGES OF CAD/CAM
● Onlays and inlays achieved with CAD/CAM are far more superior than the conventional fabrication process.
● Final product is more durable and stable.
● CAD/CAM prepared products are more aesthetic match.
● Requires less time in fabrication with exacting measurements.
