About this study
this study aimed to evaluate both clinically and radiographically the effect of flapless versus flap techniques on initial crestal bone loss and osseointegration of dental implants in lower posterior area. the study is to designed to observe the clinical outcomes such as primary stability and pain within initial hours and days and secondary stability over a 6 month period .
Read the detailed description
this clinical trial was designed to observe the clinical outcomes of techniques of implant installation including flapless and flap techniques about their effect on; osseointegration that measured by checking dental implants stability with resonance frequency analysis device after 6 months of their installation, initial crestal bone loss around the dental implants after 6 months of their installation that that evaluated radiographically and also recording pain perception by the patients within the initial hours and days after implant insertion by both techniques.The patients collected and operated from department of Oral and Maxillofacial surgery, Faculty of Dentistry, Tanta University, Egypt.
Approval of this research was obtained from Faculty of Dentistry, Tanta University Research Ethics Committee (REC). The purpose of the present study was explained to the patients and informed consents were obtained according to the guidelines on human research published by the REC at Faculty of Dentistry, Tanta University.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
flapless techniqueProcedure or surgery
taking a punch of tissue to place dental implant through surgical guide
flap techniqueProcedure or surgery
conventional flap elevation and drilling to place dental implant
tissue punchingProcedure or surgery
just a punch of tissue taken to place dental implant
| Study group | Role | What they receive |
|---|---|---|
| flapless group | Experimental | 10 patients received dental implants just by taking a punch of tissue Receives: Procedure: flapless technique; Procedure: tissue punching |
| flap group | Experimental | conventional flap elevation to place dental imp;lant Receives: Procedure: flap technique |
What is being measured
The primary outcome is the main question the study is designed to answer.
crestal bone loss and osseointegration
initial crestal bone loss around the dental implants measured radiographically and secondary stability checked after six months to check osseointegration of the dental implants by resonance frequency analysis device.
Measured: 6 months postoperatively

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 8 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 2025. 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?
crestal bone loss and osseointegration (time frame: 6 months postoperatively). 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 2025.
