Flapless Transcrestal Maxillary Sinus Floor Elevation: computer guided implant surgery 


Alveolar bone resorption and pneumatization of the maxillary sinus reduce, in many cases, the available amount of bone for the placement of dental implants in the edentulous posterior maxilla. Techniques for internal bone augmentation of the maxillary sinus floor have been established to overcome this anatomical limitation. The transcrestal approach is advocated as “minimally invasive” because of the undisturbed vascularization of the graft and reduced postoperative morbidity. The main concern related to minimally invasive sinus augmentation is the small amount of bone height and therefore a conventional lateral approach should be preferred in patients with severely resorbed maxillae. Another great concern is the risk iatrogenic perforation of sinus membrane, as the elevation is not performed under direct optical control, and because of the limited access, there is no possibility to repair the torn membrane as in the lateral surgical approach. Various modifications to the original transcrestal sinus floor elevation technique have been reported in the literature to overcome these issues: membrane elevation by inflation of a balloon catheter and the use of hydraulic pressure or negative pressure. Aim of this work is to describe a new technique for flapless transcrestal elevation of the maxillary sinus floor via CAD-CAM surgical templates in combination with hydraulics.
