Crestal sinus lift using a turbine fitted with spherical diamond- faced burs with stops: Non-traumatic technique

Introduction One of the most frequent reasons for failures during the operation of maxillary sinus floor lift is connected with the possibility of a rupture to the Schneiderian membrane which, if lacerated, cannot perform its function of graft containment. In order to reduce the incidence of complications the turbine is frequently used in association with spherical diamondfaced burs to cut the hard tissue with extreme accuracy and minor trauma, while saving the soft tissue. In this study a new technique of maxillary crestal sinus lift performed with the aid of a turbine with spherical diamond-faced burs is proposed. Calibrated stops have been created to perfectly control the procedure. Case Study The patient was a female, 47 years old, non-smoker, healthy with no systemic disease, not on regular prescribed medication, periodontally treated, who needed an operation of maxillary sinus lift. The cortical of the maxillary sinus is reduced through the use of these burs so as to obtain a hole which can enable both access to the maxillary sinus and, subsequently, the lifting of the Schneiderian membrane. Working time is reduced to less than 3 minutes in the cortical thinning operation and percussive trauma is avoided. Conclusion Due to the reduction in trauma and invasivness of the process, this technique could be a valid alternative to the techniques known and applied to date.
