"Osseodensification Efficacy on Molar Septum Expansion in Immediate Molar Implant Placement"

Septum width will be directly measured post molar extraction confirming the premeasure of the CBCT. Measurement will be recorded at the narrowest width of the septum. Implant site preparation starts with a pilot drill, in clockwise motion, in the center of the septum, until 1 mm deeper than the planned implant length. Densah® Burs (Versah, LLC, Jackson, MI, USA) were then sequentially used in OD mode (counterclockwise, drilling speed 800-1500 rpm, with copious irrigation) in small increments to gradually expand the osteotomy, until reaching the desired width for the planned implant diameter, Osteotomy diameter as a reflection of septum width expansion will then be directly measured and recorded after site instrumentation. Implants of adequate diameter (4, 4.5, or 5mm) and length (selected using preoperative CBCT) will be inserted in the prepared osteotomies to engage the bone apical to the socket, insertion torque will be measured using the torque wrench and ISQ values

Septum width will be directly measured post molar extraction confirming the premeasure of the CBCT. Measurement will be recorded at the narrowest width of the septum. The initial (pointed) drill will be used to make a hole (starting point) in the interradicular bone to avoid slippage of the subsequent the drills in the socket of the remaining roots. The drills of increasing diameters will be used to complete the implant osteotomy according to manufacturer instructions. In case of limited interradicular bone volume, drilling will be made at the socket of mesial or distal roots. Osteotomy diameter as a reflection of septum width expansion will then be directly measured and recorded after site instrumentation. Implants of adequate diameter (4, 4.5, or 5mm) and length (selected using preoperative CBCT) will be inserted in the prepared osteotomies to engage the bone apical to the socket insertion torque will be measured using the torque wrench and ISQ values
