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
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
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
