What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
IMPLANTProcedure or surgery
six implants will be placed in the maxilla in the following area ( canine , premolar , molar )
| Study group | Role | What they receive |
|---|---|---|
| Group I: PARALLEL | Active comparator | Group I: Six compressive implants will be installed parallel to each other in the canine and 2nd premolar areas Receives: Procedure: IMPLANT |
| Group 2: inclined | Active comparator | Group II: Six compressive implants will be installed with two posterior inclined implants. Receives: Procedure: IMPLANT |
What is being measured
The primary outcome is the main question the study is designed to answer.
implant stability
Implant stability will be measured by ISQ using an Ostell device
Measured: 6 months
Secondary outcomes (3)
plaque index
plaque index will be measured with periodontal probe according to the following score 0; absence plaque , score 1; plaque only detected by a probe passing through the smooth marginal surface of the implant, score 2; plaque can be recognized by naked eye, and score 3; plenty of soft matter.
Measured: one year
gingival index
gingival index and bleeding will be measured using periodontal probe according to the following score ; 0; no bleeding when a periodontal probe is passed along the mucosal margin, 1;isolated bleeding spots visible, 2; blood forms a confluent red line on the mucosal margin, 3;heavy or profuse bleeding
Measured: one year
Pocket Depth
Pocket Depth around implant will be measured by mm using periodontal probe
Measured: one year

Questions about this trial
What is this clinical trial studying?
A study testing IMPLANT in people with Compressive Implants, run by Mansoura 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 1 inclusion and 1 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 27 Mar 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 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
implant stability (time frame: 6 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 27 Mar 2026.
