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
