About this study
Official title: Comparative Assessment of Primary Stability in Double, and Triple Thread Implant Designs in the Posterior Maxilla
The goal of this randomized clinical trial is to compare the primary stability of double-thread and triple-thread dental implant designs in patients requiring implant placement in the posterior maxilla.
The main question it aims to answer is whether implant thread design influences primary implant stability in the posterior maxilla.
Participants will be randomly assigned to one of two groups. Group A will receive a double-thread dental implant, while Group B will receive a triple-thread dental implant. Primary implant stability will be assessed at the time of implant placement using insertion torque and resonance frequency analysis (ISQ).implant stability using ISQ will also be evaluated at 3 months

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
triple thread dental implantDevice
Participants assigned to this group will receive a triple-thread dental implant placed in the posterior maxilla. Primary implant stability will be assessed at the time of implant placement using insertion torque and resonance frequency analysis (ISQ).
double thread dental implantDevice
Participants assigned to this group will receive a double-thread dental implant placed in the posterior maxilla. Primary implant stability will be assessed at the time of implant placement using insertion torque and resonance frequency analysis (ISQ).
| Study group | Role | What they receive |
|---|---|---|
| Double-Thread Implant Group | Experimental | Participants assigned to this arm will receive a double-thread dental implant in the posterior maxilla Receives: Device: double thread dental implant |
| Triple-thread implant | Experimental | Participants assigned to this group will receive a triple-thread dental implant placed in the posterior maxilla. Primary implant stability will be assessed at the time of implant placement using insertion torque and resonance frequency analysis (ISQ). Receives: Device: triple thread dental implant |
What is being measured
The primary outcome is the main question the study is designed to answer.
insertion torque
The primary outcome of this study will be the insertion torque, expressed in Newton-centimeter (Ncm). Measurements will be performed using a surgical motor/torque wrench and recorded at the time of implant placement (T0).
Measured: at the time of implant placement T0
Secondary outcomes (1)
implant stability (ISQ)
The first secondary outcome will be the assessment of implant stability (ISQ) using the Osstell ISQ device. The measurements will be expressed on the ISQ scale (1-100) and recorded at the time of implant placement (T0).
The second secondary outcome will also be the evaluation of implant stability (ISQ), assessed with the Osstell ISQ device on the ISQ scale (1-100), but recorded at 3 months, corresponding to the prosthetic stage
Measured: 3 months

Questions about this trial
What is this clinical trial studying?
A study testing triple thread dental implant and double thread dental implant in people with Dental Implant and Primary Stability of the Implants, run by Future University 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 5 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: opening soon, as of the sponsor's last update on 26 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
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 falah M Alshahrani, BDS (0561554512 ext. 00966599224538, alhmadflah@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
insertion torque (time frame: at the time of implant placement T0). 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 26 Aug 2026.
