Conditions
Summary
The goal of this clinical trial is to evaluate the effectiveness of dynamic navigation in full-arch dental implant placement in patients with complete maxillary edentulism. The main questions it aims to answer are: * the accuracy of nasopalatine implants, trans-sinus implants, and trans-nasal implants placement in the anterior maxillary bone with dynamic navigation * the clinical effectiveness of nasopalatine implants, trans-sinus implants, and trans-nasal implants in full-arch rehabilitation * the correlation between the anatomical features of the nasal cavity and the anterior sinus wall on CBCT images and their influence on nasopalatine implants, trans-sinus implants, and trans-nasal implants position
Eligibility
Inclusion Criteria3
- Aged 18 years or older
- Good overall health (Class 1 and 2 according to the American Society of Anesthesiologists classification system)
- Clinical diagnosis of complete edentulism of the upper arch classified as Class IV to VI according to Cawood and Howell
Exclusion Criteria4
- Systemic or local conditions that may affect surgery, wound healing, or bone integration, such as cardiovascular diseases, diabetes, bone-related diseases, or medication affecting bone metabolism
- Smoking more than 10 cigarettes per day
- Presence of acute infections in the planned implant site
- Limited mouth opening of less than 40mm

Interventions
Pre-surgery (Implant Placement): Clinical examination, panoramic radiography, film guide creation, and CBCT imaging will be performed. Based on CBCT data and the film guide, bone measurements will be taken, and a treatment plan with virtual implants will be developed. 4-6 pilot holes will be made, adjusting for critical structures like the maxillary sinus, inferior alveolar nerve, and planned implant sites. Full blood count and coagulation tests will be done. During Surgery: Implant surgery will be performed under local anesthesia/sedation. Incision and mucosal flap reflection will expose the implant site. A clip will be fixed to the anterior maxilla with screws, connected to the monitoring device. The dynamic navigation system will guide the placement of nasopalatine, trans-sinus, and trans-nasal implants, ensuring optimal placement. Post-surgery: Post-operative CBCT will be performed to check the implant positions, confirming the accuracy of the implant placement.
