Study Summary The goal of this clinical trial is to evaluate whether a newly designed Advanced Intelligent drill can improve the safety and effectiveness of Maxillary Sinus Floor Augmentation (MSFA) procedures in adults with insufficient bone height in the posterior maxilla for dental implants. The main questions it aims to answer are: * Can the AI drill reduce the risk of Schneiderian membrane perforation compared to traditional drilling methods? * Does the AI drill improve the efficiency of window preparation during the procedure? The researcher compares the outcomes of participants treated with the AI drill to those treated with a traditional rotary drill to see if the AI drill leads to fewer complications (less membrane perforations, bleeding and postoperative complications) and better surgical outcomes. Participants will: * Undergo MSFA using either the AI-powered drill or the traditional rotary drill. * Attend follow-up appointments to monitor healing and outcomes, including imaging and clinical evaluations. This study hopes to advance surgical techniques for safer and more effective preparation for dental implants.
