The maxillary sinus lift technique known as sinus lift procedures in order to put implants is the most studied, most common, most developed in dentistry oral surgery.
In this technique, buccal approach, we lift the Schneiderian membrane but before is necessary make a huge flap in the vestibular zone of the maxilla in order to obtain the bone exposition and then we can make a hole in the bone and only at this moment we can try to lift the membrane.
We can understand this procedure really invasive.
In this last period, the concept of mini-invasive surgery has interested many surgeries in dentistry and of course also bone surgery before the implant.
The mini-invasive crestal approach for sinus lift was just developed by Baldi (Sinus floor elevation using osteotomes or piezoelectric surgery D. Baldi, et al Int. J. Oral Maxillofac. Surg. 2011; 40: 497–503).
Of course, the development, growing and diffusion of mini-invasive surgery was possible thank to technological innovation as endoscopic instruments and Piezosurgery (we can cut the bone with the ultrasonic device without damaging soft tissue).
The use of these two techniques together allows us to achieve a reduction of surgery time, morbidity, healing time and also the healing quality and above all the best patient’s compliance.
