|
Purpose: To evaluate the accuracy of zirconia copings in terms of clinical verified for the clinical application of CAD/CAM.
Methods: Zirconia copings (n=5) were prepared using CAD/CAM system and were sintered using the relevant electrical induction furnace, which uses a 2h sintering program with a maximum temperature of . The copings placed at the models and the interval values were measured.
Results: The meas interval values between the die and the zirconia copings were (A), (B), (C). 51.05 (D).
Conslusion: The maximum interval values between the die and the zirconia copings were which is acceptable for clinical use. Proper understanding of the test conditions will help enhancing the accuracy of zirconia coping.
