Toca Aqua KitThe DSI Toca Aqua Kit was designed specifically for the sinus lifting crestal approach. This technique is preferred by many as it is less invasive and generally has fewer risks associated with it than other approaches. It also tends to result in a faster recovery time, with fewer post operative issues. The crestal approach can be an effective solution for elevating the maxillary sinus membrane without significant stress or discomfort to the patient.
