Objectives: To compare the clinical and radiographic outcomes of two sinus floor elevation techniques: the conventional lateral window technique versus the transalveolar approach using a hydrodynamic ultrasonic device.
Materials And Methods: The study was designed as a randomized controlled clinical trial, and participants were randomly allocated to the control group (lateral window: LW) or to the test group (hydrodynamic transalveolar approach: HTA). The intraoperative and postoperative data, including procedure duration and patient-reported outcome measures (PROMs), were collected during the surgery and up to 1 year post-surgery.
