MAXILLARY SINUS LIFT BY CRESTAL (OR TRANS-ALVEOLAR) APPROACH
The maxillary sinus lift is a procedure performed to increase the amount of bone in the molar area of the upper arch to prepare it for the placement of one or more dental implants.
When upper molars are lost, the sinus cavity tends to move closer to the maxillary ridge; over the time, the edges of the cavity can be so near to the ridge that there is no bone left to place implants.
By “raising” the Schneider’s membrane that covers the floor of the maxillary sinus, the dentist is able to add autologous, heterologous or synthetic bone materials to re-create the adequate conditions for implant placement.
After the incision, use the twist drill for initial preparation.
The purpose of these drills is to perform a preparation up to 1-2 mm from the floor of the maxillary sinus.
The drilling depth can be adjusted using the drill stops included in the kit.
The drill-stops intended for the Rialto kit can be identified by the laser marking “SL” on each drill stop.
These drills must not come into contact with the Schneider’s membrane as the cutting edges may perforate the sinus mucosa.
