Modelling Intra-Sinus Fluid Movements and Drainage Through Computational Fluid Dynamics Before and After Maxillary Sinus Augmentation: A Simulation-Based Pilot Study.

: Sinus lifting, a procedure to augment bone in the maxilla, may cause complications such as sinusitis due to impaired drainage. This study aimed to assess how sinus lifting impacts airflow in the sinus cavity, which is essential for patients undergoing dental implants. Using computational fluid dynamics (CFD), this research analyzed airflow changes after sinus floor elevation, offering insights into the aerodynamic consequences of the procedure.
