ABSTRACT
Objective To test the fracture loading of extracted cracked teeth with CEREC CAD/CAM ceramic inlays/onlays. Methods All the extracted teeth were divided into two groups (A control group; B test group; n=15 teeth in each group). All the teeth were prepared into those imitating cracked teeth. Those teeth in group B were strengthened with CEREC CAD/CAM ceramic inlays/onlays. All teeth were thermocycled and mounted for testing and then were loaded until fracture. Results The force of anti-fracture of extracted teeth imitating cracked teeth with CEREC CAD/CAM ceramic inlays/onlays (group B) was obviously higher than that of the teeth without CEREC CAD/CAM ceramic inlays/onlays (group A). Conclusion CEREC CAD/CAM ceramic inlays/onlays can effectively prevent the crack of teeth in clinical practice.
