Use of standard zirconia abutments yield better esthetic outcomes compared with titanium abutments

Results

Twenty-five subjects completed the follow-up visits at 1 and 5 years. ICAI values showed statistically significant better aesthetic outcomes when zirconia abutments were used compared to titanium abutments. Between 1 and 5 years, the aesthetic sub-analysis of the crown component worsened but the mucosal sub-analysis improved. There were no significant changes in bone levels, but the plaque index, bleeding on probing, and probing depths worsened in both groups.

At 5 years, standard zirconia abutments achieved better aesthetic outcomes, although with similar clinical behaviour.
