NEW PROCEDURE FOR SINUS LIFT USING A MICROSCOPE

抄録

Two common methods for performing sinus lift for implant therapy are the lateral approach and the vertical approach. The vertical approach is more commonly used at present and is considered highly atraumatic, but is essentially performed blindly. As a result, perforations in the mucosa often pass unnoticed. In addition, there is a tendency for beginners to readily use this approach because of its comparative simplicity, resulting in the occasional patient with poor progress. The procedure could be carried out more safely if the mucosa could be viewed during the vertical approach while peeling away the flap, similar to the lateral approach. The field of vision thus needs to be expanded using a microscope. We used a specially developed raspatory and sinus balloons to successfully achieve sufficient elevation of the sinus floor. This technique enables a safe, atraumatic operation, and is potentially applicable to retreatment in patients in whom the initial implant does not survive.
