Abstract:
Objective:To explore the influence of different cement spaces on the marginal adaptation of CAD/CAM zirconia inlay.
Methods:30 teeth extracted for orthodontic purpose were selected and divided into 3 groups (Group A 10 μm, Group B 30 μm, Group C 50 μm). The marginal spaces of inlays were recorded by the light-body Silicone impression material, and measured by microscope. The data were analyzed by SPSS 13.0.
Results : All the inlays fitted very well and all the marginal spaces were less than 120 μm. The shoulder of Group A was statistically lower than Group B and Group C (P < 0.05). The axial surface of Group B was statistically lower than Group C (P < 0.05).
Conclusions :CEREC zirconia inlay is satisfactory when the cement space is between 10-50 μm.
