In cases involving the bonding of CAD/CAM crowns, I honestly feel that I cannot work without ZOO (laugh).
Recently, CAD/CAM crowns have become very common in our insurance-based prosthetic treatments in Japan.
They now account for nearly half of the prosthetic restorations we place.
No matter how good the adhesive material is, if proper dryness cannot be achieved in the oral cavity, the crown is much more likely to debond.
One small clinical tip I would like to share is this:
When seating the crown, I create small dimples on the abutment tooth using a turbine bur.
This simple step significantly reduces the risk of debonding.
Of course, using ZOO to maintain proper dryness is essential.
Over the past three years, I have not experienced any debonding cases when using this approach.
As long as the patient is not a severe bruxer, the results have been very stable.
Recently, the insurance restrictions for CAD/CAM crowns in Japan have been relaxed, so I expect that the opportunity to use ZOO in these cases will continue to increase.
