Effect of cement space on the marginal fit of CADCAM
#0183;#32;Evidence suggests that the cement space of CADCAM zirconia crown restorations should be set at no smaller than 60 m for better seating on the abutment with minimal need of manual adaptation. 29 An et al 36 evaluated the marginal fit of zirconia copings with simulated die spacer set at 60 m and calculated overall mean vertical discrepancy value of 104 m.
