About this study
Official title: Accuracy Of Mandibular Reconstruction Using Fibula Free Flaps With Patient Specific Plates And Immediate Dental Implants In Fresh Versus Delayed Cases A Non Randomized Clinical Trial
The goal of this clinical trial is to learn if mandibular reconstruction with immediate dental implants is as accurate in fresh cases and delayed cases
The accuracy of the fibular segments and dental implants will be compared in both groups
Participants will:
undergo a preoperative CT scan with VSP for mandibular reconstruction Undergo the surgical procedure Undergo an immediate postoperative CT scan and have it superimposed on the virtual plan to detect inaccuracies

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
fibula free flapProcedure or surgery
Immediate reconstruction with the use of PSIs and dental implants in fresh and delayed cases
| Study group | Role | What they receive |
|---|---|---|
| Fresh cases | Active comparator | Cases needing mandibular resection and reconstruction with no prior intervention history Receives: Procedure: fibula free flap |
| Delayed cases | Experimental | Cases needing mandibular reconstruction with history of prior intervention in the form of resection and/or hardware placement Receives: Procedure: fibula free flap |
What is being measured
The primary outcome is the main question the study is designed to answer.
Accuracy of the fibular segments and dental implants
Accuracy of the fibular segments and dental implants in patients compared to the Virtual Surgical plan, Measured in degrees and millimeters
Measured: From enrollment "VSP" till the immediate postoperative CT, Throughout the completion of the study, for an average of 1 year

Questions about this trial
What is this clinical trial studying?
A study testing fibula free flap in people with Mandible Reconstruction, run by Cairo 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 4 inclusion and 6 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: under way, not looking for participants, as of the sponsor's last update on 5 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?
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?
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?
Accuracy of the fibular segments and dental implants (time frame: From enrollment "VSP" till the immediate postoperative CT, Throughout the completion of the study, for an average of 1 year). 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 5 Mar 2026.
