CEREC
This is the most recent computerized technology for the preparation of crowns ,veneers,onlays,inlays.
Teeth can be restored in a single sitting with the patient,rather than multiple sittings required with earlier techniques.
The teeth are prepared and then photographed using a special type of cameras that give a 3D digital model. A properietary software is then used to approximate the restoration shape in comparison to the surrounding teeth. The practitioner then refines that model using 3D CAD computer aided design software .When the design phase is complete, the information is sent to the milling unit which mills the actual restoration from a solid ceramic block using diamond burs. The restoration is then bonded to the tooth.
