Why it matters for dental
For specialists and practices placing posterior implants, this RCT shows that standardized titanium-base and custom titanium abutments for monolithic zirconia crowns had comparable 3-year marginal bone level stability, survival, and patient satisfaction with no major technical complications.
Key points
- 01
Fifty-one patients attended the 3-year follow-up; 28 received crowns on standardized titanium bases and 23 received crowns on custom titanium abutments.
- 02
No implants or crowns were lost at 3 years in either group.
- 03
Median marginal bone level changes from baseline to 3 years were statistically similar between the two abutment types (p > 0.05).
- 04
One minor zirconia chip occurred in the titanium-base group, yielding a 3.6 % technical complication rate; all other biological and technical outcomes were comparable (p > 0.05).
