Comparing two types of dental implants over five years
Official title: Comparative Performance of Two-piece Zirconia Tissue Level Implants vs. Titanium Bone Level Implants Placed With a Fully Digital Workflow - 5-year Follow up of a Randomized Clinical Trial
Run by The University of Hong Kong · NCT05326880 · Data updated 2026-11-12
This study is testing whether a new ceramic dental implant works better and is safer than a traditional titanium implant for replacing single teeth over five years.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults aged 18 and older who require a single tooth replacement in the premolar-to-premolar area and can comply with study protocols.
✕Probably not a fit
Patients with conditions that may interfere with study participation or those who are pregnant will not benefit from this study.

What this trial studies
This study is a post-market, randomized-controlled trial designed to compare the medium-term performance and safety of two types of dental implants: the Straumann PURE 2-piece Ceramic Implant and the Straumann Bone Level Implant. It aims to evaluate the occurrence of biological and technical complications, as well as patient satisfaction and aesthetic outcomes over a five-year period. Participants will receive either a ceramic or titanium implant for single tooth replacement in the premolar-to-premolar area, and their progress will be monitored through scheduled follow-up visits. The study utilizes a fully digital workflow to enhance the accuracy and efficiency of the implant procedures.
Why it matters
Potential benefit: If successful, this study could provide insights into which type of dental implant offers better long-term performance and patient satisfaction.
How similar studies have gone: Previous studies have shown varying success with different types of dental implants, but this specific comparison of zirconia versus titanium implants is relatively novel.

Show full inclusion / exclusion criteria
Inclusion Criteria: following criteria must be met for inclusion in the study: * Patients must have voluntarily signed the Informed Consent Form before any study related procedures are performed, are willing and able to attend scheduled follow-up visits and agree that the pseudonymized data will be collected, analyzed, and published. * Patients must be males or females who are a minimum of 18 years of age. * Patients, who have received a single tooth replacement with a study implant as per-protocol in the premolar-to-premolar area (excluding lower incisors) in the mandible and maxilla and restored with a screw retained ceramic crown. Exclusion Criteria: * Patients with conditions or circumstances, in the opinion of the Investigator, which would prevent completion of study participation or interfere with analysis of study results, such as history of non-compliance or unreliability. * Pregnancy or intention to become pregnant at any point during the study duration.
