TI  - The Effect of CAD/CAM Crown Material and Cement Type on Retention to Implant 
      Abutments.

AB  - PURPOSE: To evaluate the pullout resistance of CAD/CAM implant-supported crowns 
      cemented with provisional and definitive cements on Ti-base implant abutments. 
      MATERIALS AND METHODS: Sixty crowns were milled for use in Ti-base implant 
      abutments and divided (n = 15/group) according to material, as follows: (a) [Pr] 
      Temporary acrylic resin; (b) [Co-Cr] Cobalt-Chromium alloy; (c) [Zr] 
      polycrystalline zirconia; and (d) [Ti] titanium. The cementation was performed 
      with RelyX Temp NE (RxT) cement or RelyX U200 self-etching resin cement, under a 
      50 N (5 kg) load for 10 minutes. Twenty-four hours after cementation, the crowns 
      were subjected to the pullout test in a universal test machine, at a 1.0 mm/min 
      crosshead speed. The tests were performed first without cement to evaluate 
      frictional resistance (Baseline), then with provisional cement (RelyX Temp NE 
      without cement again (Baseline After RxT), and finally with resin cement (U200). 
      The results were analyzed by ANOVA and Tukey test (p < 0.05). RESULTS: Data 
      evaluation as a function of cement type demonstrated the superiority of 
      resin-based cements relative to provisional and baseline groups (p < 0.01). While 
      Co-Cr crowns presented the highest pullout strength values, Pr showed the lowest 
      values (data collapsed over cement) (p < 0.001). Retentiveness data as a function 
      of both factors demonstrated similar pullout resistance between groups without 
      cement (p < 0.001), except Zr baseline. Also, Co-Cr presented higher pullout 
      strength compared to other materials. CONCLUSIONS: Self-adhesive resin cement 
      exhibited superior retention compared to temporary cement, regardless of crown 
      material. Co-Cr and titanium presented higher levels of retention to Ti-base 
      abutment after being cemented.
