What this Trial Is About
Researchers are studying the use of dynamic navigation technology to improve the placement of full-arch dental implants in patients with complete upper jaw tooth loss or significant bone loss. The study focuses on evaluating the accuracy and clinical success of nasopalatine, trans-sinus, and trans-nasal implants, while also examining how anatomical features of the nasal cavity and sinus wall seen in CBCT scans affect implant positioning. This research aims to enhance treatment outcomes for patients requiring full-arch rehabilitation. The study involves detailed imaging and planning before surgery, including clinical exams, panoramic X-rays, film guide fabrication, and CBCT scans. During surgery, implants are placed using a dynamic navigation system that guides the precise positioning of nasopalatine, trans-sinus, and trans-nasal implants. Post-surgery, CBCT scans verify implant placement accuracy, followed by careful post-operative care and scheduled follow-up visits over six months, ending with permanent restoration of the implants. Participants will undergo multiple assessments including CBCT imaging, bone measurements, blood tests, and clinical evaluations before, during, and after implant placement. Researchers will measure implant positioning accuracy using 3D deviation and angular deviation metrics, as well as implant stability and survival rate over six months. Regular follow-ups will monitor healing and success of the implants, with the total study period spanning from enrollment through six months post-surgery.

Your Study Journey
Screening
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 screening and enrollment visit (in-person)
Treatment
Duration - Surgery day plus immediate post-operative period
Participants undergo full-arch dental implant placement using dynamic navigation technology. This includes clinical examinations, imaging, pilot hole placement, and implant surgery under local anesthesia or sedation with dynamic navigation guidance to ensure precise implant positioning.
1 implant surgery visit (in-person)
Post-operative Follow-up
Duration - 6 months
Participants receive post-operative care including medications and site care instructions, provisional restorations, and attend follow-up visits to monitor healing and implant stability. Permanent restorations are completed at 6 months post-surgery.
Follow-up visits on Days 3, 7, 14, Month 1, Month 3, and Month 6 (in-person)
