A sinus lift is currently one of the most commonly performed augmentation procedures. There are a few methods for this bone augmentation. They differ between the minimum trauma, the surgical difficulty and the percentage perforation of the Schneider membrane. Lateral antrostomy using the Caldwell Luc surgical procedure is the most common but still the most traumatic one for the patient. Hence, a great deal of effort is being put in in order to find less traumatic but at the same time more predictable (reducing potential complications) techniques. These surgical procedures include hydrodynamic piezoelectric methods for extending the Schneider membrane. Unfortunately, the literature on this specific topic is extremely limited. In the largest library, PubMed, there are less than 10 articles on these innovative techniques. In the following article, sinus lift surgical procedures were performed with a W&H surgical device utilizing a hydrodynamic piezoelectric technique in all cases (Ziętek Piezo Crestal Lift Concept®).
