Dynamic navigation versus pre-made guides for placing upper-jaw dental implants
Official title: Accuracy Assessment of Dynamic Vs. Static Navigation Implant Placement Protocols (Randomized Controlled Trial)
Run by Ain Shams University · NCT07291336 · Data updated 2026-11-12
This will test whether using a real-time dynamic navigation screen or a pre-made surgical guide gives more accurate implant placement for healthy adults missing an upper tooth.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are healthy adults aged 22 or older with at least one missing tooth in the upper jaw between the right and left second premolars, at least six remaining teeth in that jaw, and at least 5 mm of available bone.
✕Probably not a fit
Patients who need bone augmentation, have poor oral hygiene, heavy smoking, uncontrolled systemic disease, pregnancy, or prior head/neck radiotherapy are unlikely to benefit or be eligible for this protocol.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Participants who are at least 22 years old and meet bone and tooth-count requirements will have implant placement planned from x-rays and impressions. They will be assigned to either a static workflow using a fabricated surgical guide or a dynamic navigation workflow where the surgeon follows real-time screen guidance during drilling and implant insertion. Accuracy of the final implant position will be measured against the preoperative plan to compare the two approaches. All procedures and follow-up visits take place at the dental faculty site in Cairo and standard clinical safety criteria are applied.
Why it matters
Potential benefit: If successful, the comparison could identify a method that improves implant placement accuracy and reduces positioning errors and complications.
How similar studies have gone: Prior clinical work has shown mixed but generally favorable results for dynamic navigation, with some studies reporting similar or improved placement accuracy compared with static guides.
