Abstract
An ultrasonic sinus membrane/periosteum separation tool set consisting of a cutting tool and a spray nozzle for use with a hand piece of an ultrasonic machine is disclosed. The cutting tool has a connection base, a pole and a cutter tip. The spray nozzle has a connection base, a pole and an operating tip. The pole extends from the connection base, having a longitudinal fluid passage for the passing of a fluid and a fluid injection hole for injecting a fluid into a hole made on the alveolar ridge of the gingiva of the patient to be treated. The cutter tip and the operating tip each have jet holes for ejecting a fluid radial in jets, facilitating sinus augmentation (sinus lift or sinus graft). The ultrasonic sinus membrane/periosteum separation tool set can also be used in an upper/lower jaw deformity implant surgery.
