Zirconia crowns on titanium abutments: 5-year study
Part of Mouth & dental clinical trials.
This study checks how well a type of ceramic crown (zirconia) attached to a titanium base works for replacing a single missing back tooth. It looks at results 5 years after treatment.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You were treated for a missing back tooth (premolar or molar) 5 years ago with a dental implant and a screw-retained zirconia crown.
- You were 18 or older at the time of treatment.
- The implant site had enough healthy bone for an implant at least 8mm long and 4.2mm wide with good stability.
- You had no infection at the implant site and good oral hygiene at that time.
- You did not have severe gum disease, bruxism (teeth grinding), smoke, or had radiation to the head or neck.

This trial tests two types of zirconia (ceramic) dental implants for replacing a single missing upper premolar. It aims to see which implant platform works best for long-term stability.
This study checks how well two kinds of dental implants (zirconia and titanium) work over 5 years in replacing a single tooth. You may be included if you already received the specific implant type and restoration the study requires and you can attend regular checkups.
This study tests how well zirconia crowns (tooth-colored caps) perform when placed on dental implants in the back of the mouth. It aims to see if they are a good, long-lasting option for replacing a single missing tooth.
This study looks at how well a full set of replacement teeth made of a strong material called zirconia (a type of ceramic) work when placed on dental implants in the mouth. It aims to understand the long-term success and behavior of these restorations after at least a year.
This study compares two types of material (zirconia or titanium) used as a frame in full-arch screw-retained implant bridges. It aims to find which material has fewer complications, helps patients who have lost all teeth in one or both jaws.
This trial looks at how well a zirconia (ceramic) full set of dental implants and crowns heals over time. It may help people who need a complete upper and/or lower replacement to understand expected healing and fit.
