What is being measured
The primary outcome is the main question the study is designed to answer.
Crestal bone changes
Measuring the amount of marginal(crestal) bone changes either loss or gain around the dental implants using the cone beam computed tomography(CBCT) in millimeter scales about the original marginal bone height measured at the time of the visit of final (definitive) prosthetic loading.
The positive(+ve) values mean an increase (gain) in the marginal bone height around the implants, the more the +ve value, the more the gain in the bone height which is the better outcome, while the negative (-ve) values mean decrease (loss) in the marginal bone height around the implants, the more the -ve value, the more loss in the bone height, which is the worse outcome.
Measured: 12 months
Secondary outcomes (1)
Patients Satisfaction
measuring the degree of patient satisfaction using a Patient's Denture Assessment (PDA) questionnaire, via a Likert scale which uses a 5-point system from 1 to 5, All items are scored as follows: unsatisfactory =1 hardly satisfactory =2 moderately satisfactory=3 very satisfactory=4 excellent satisfaction=5 The greater (higher) the score, the more patient satisfaction, which is the better outcome, while the weaker (lower) the score, the less is patient satisfaction, which is the worse outcome.
Measured: 12 months

Questions about this trial
What is this clinical trial studying?
A study testing One-piece zirconia dental implants and One-piece titanium dental implants in people with Complete Edentulism, run by Ain Shams University at 1 site in Egypt.
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 5 inclusion and 10 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: looking for participants now, as of the sponsor's last update on 22 Oct 2024. 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 Egypt. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Mohammad Irakky, masters (00201111232777, implanteeth@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Crestal bone changes (time frame: 12 months). 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 22 Oct 2024; AzTrials last refreshed its copy on 6 Nov 2026.
