【Abstract】 The fit of a crown is fundamental for the clinical success of a restoration.The purpose of this study is to investigate whether the crown fit of a new Titanium alloy (Nickel-Chromium-Titanium-alloy)is suitable for clinical application.The results showed the distance of margin was (38 0989±11 7933)μm,axial wall(54 5956±10 1848)μm,conical cusp (30 9389±11 2219)μm,occlusal(40 8278±9 6343)μm,in Nickel-Chromium-Ti Alloy metal crown.There was no significant difference between these two dental materials ( P <0 05)(two-way ANAOV).Both Nickel-Chromium-Titanium alloy and Nickel-Chromium alloy had nice marginal seal and internal seal and both artificial crowns were clinically acceptable.更多还原
