Comparison of Different Cleaning Procedures for Decontaminating Zirconium Oxide Surface After Polishing.

Purpose: To evaluate the efficacy of cleaning protocols for the decontamination of organic compounds from polished zirconium oxide samples.

Materials And Methods: A total of 24 rectangular plate specimens were sintered from zirconium oxide. All samples were polished with commercially available polishers (coarse, fine, and superfine) and polishing paste.

Influence of Cement Type on its Quality of Removal from Zirconium Oxide Implant-Supported Restorations.

Purpose: To assess excess cement removal after cementation of implant-supported cementretained restorations using different cements.

Materials And Methods: A dental model with soft tissue imitation, 20 individual zirconium oxide abutments, and 20 zirconium oxide crowns were fabricated. Half of the restorations were cemented using resin cement (RX) and the other half with resin-modified glass-ionomer cement (GC).

The Effect of a Polishing Protocol on the Surface Roughness of Zirconium Oxide.

Purpose: To evaluate the surface roughness values of zirconium oxide samples that were gradually polished using a commercially available polishing system and polishing paste.

Materials And Methods: A total of 50 rectangular specimens of predetermined size (10 × 10 × 3 mm) were sintered from zirconium oxide. Samples were randomly assigned to one of five groups (n = 10 each): control, coarse (Co), fine (F), super fine (SF), or polishing paste (PP).
