Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Study population: These will be patients who are otherwise seeking dental implant therapy and belong to the study centers' standard patient population.
Who may be able to join
- patients of either sex and any race greater than 18 years of age
- patients for whom a decision has already been made to use dental implants for treating an existing dental condition specifically:
- dental implants restored as single tooth replacements, short and long fixed bridges, overdenture, or fixed full denture.
- a temporary healing abutment will be placed on implant during implant placement surgery (single stage procedure).
- patients must be physically able to tolerate conventional surgical and restorative procedures
- patients must agree to be evaluated for each study visit, especially the yearly follow-up visit
Who cannot join
- patients with active infection or severe inflammation in the areas intended for implant placement
- patients with a >10 cigarette per day smoking habit
- patients with uncontrolled diabetes mellitus
- patients with metabolic bone disease
- patients who have had treatment with therapeutic radiation to the head within the past 12 months
- patients in need of allogenic bone grafting at the site of the intended study implant for augmentation purposes. Grafting for treatment of dehiscence or fenestration must have occurred at least 8 weeks prior to implant placement surgery

- patients who are pregnant at the screening visit
- patients with evidence of severe para-functional habits such as bruxing or clenching
- patients with less than 6 weeks of healing time post tooth extraction at the intended treatment site

About this study
Official title: Observational Study of Certain Prevail Implant System in Maxillary and Mandibular Regions
This observational, prospective clinical study evaluates the performance of the Certain Prevail implant system to show potential crestal bone and soft tissue preservation following the crestal bone. It will also evaluate implant performance.
Study (null) hypothesis: The preservation of crestal bone for the Certain Prevail implants will be the same as that for standard non-platform switched implants from contemporaneous studies (historical controls).
Read the detailed description
This is a prospective, observational study of patients with partial or complete edentulism treated with the Certain Prevail dental implants. Restorations will consist of single tooth replacements, short and long fixed bridges, and overdentures and full dentures. All implants are placed using a single stage approach and temporalization occurring after two months of healing (early loading). Each center will strive to enroll a total of 20 patients.

Questions about this trial
What is this clinical trial studying?
An observational study of Partial Edentulism, run by ZimVie at 1 site in Austria.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 8 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Austria. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 17 Aug 2009). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Osseous Integration (time frame: 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Sep 2026.
