SINUS FLOOR WITH OSSEODENSIFICATION OR LATERAL WINDOW

Access to the bone crest will be performed through a slightly palatinized crestal incision, and a full-thickness mucoperiosteal flap will be elevated. Implant site preparation will be performed according to the bone densification drilling sequence established by the Densah® technique protocol

A full-thickness mucoperiosteal flap will be elevated. The lateral window will be made with a spherical diamond drill (number 8) at 20,000 rpm. The mesiodistal and apicocoronal dimensions of the lateral access window to the sinus will be measured in all the participants using a caliper. Sinus membrane elevation will be performed with manual instruments.
