What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Densah Bur OsseodensificationProcedure or surgery
Osteotomy site preparation using sequential Densah burs in reverse (counterclockwise) condensing mode at 800-1500 rpm with copious sterile saline irrigation and gentle pumping motion to preserve and compact bone.
Modified Conventional DrillingProcedure or surgery
Sequential conventional drilling with the final drill operated in counterclockwise rotation to condense bone.
| Study group | Role | What they receive |
|---|---|---|
| Densah Bur Group | Experimental | Osteotomy site preparation using Densah burs in reverse (counterclockwise) condensing mode at 800-1500 rpm with copious sterile irrigation and gentle pumping motion, followed by early loading after 2 months. Receives: Procedure: Densah Bur Osseodensification |
| Modified Conventional Drilling Group | Experimental | Osteotomy site preparation using conventional drills sequentially in a clockwise direction, with the final drill operated in a counterclockwise direction, followed by early loading after 2 months. Receives: Procedure: Modified Conventional Drilling |
What is being measured
The primary outcome is the main question the study is designed to answer.
Implant Stability Quotient (ISQ)
Implant stability measured using Resonance Frequency Analysis (RFA) with the Osstell Mentor device and SmartPeg. Measurements were recorded in four directions (every 90 degrees) and averaged per implant to provide an ISQ score (scale: 1 to 100, where higher scores indicate greater stability).
Measured: 12 months

Primary outcome
Implant Stability Quotient (ISQ)
Time frame: 12 months
Implant stability measured using Resonance Frequency Analysis (RFA) with the Osstell Mentor device and SmartPeg. Measurements were recorded in four directions (every 90 degrees) and averaged per implant to provide an ISQ score (scale: 1 to 100, where higher scores indicate greater stability).
Results and safety
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

Questions about this trial
What is this clinical trial studying?
A study testing Densah Bur Osseodensification and Modified Conventional Drilling in people with Jaw, Edentulous, Partially and Dental Implant Failure, 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 10 inclusion and 4 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 30 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 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 Quotient (ISQ) (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 30 Sep 2026.
