Wide implant placement in the sinus-lifted maxilla and native bone


Preoperative radiograph shows 5mm of available bone height on #16


Flap raising on site 16

Site preparation was done with Ø3.6 S-reamer at 1200rpm.

In the S-reamer drilling, bone chips produced a wide and flat bony surface on the cross-section of the head, which prevents perforation of the sinus Schneiderian membrane.

Taper drill designed for S-wide implant

Site 16 was prepared to place Ø6.0*7.0mm S-wide EB implant.

ф6.0*7.0mm S-wide EB implant in place

Immediate loading was planned due to 45N/cm of excellent stability achieved in the inferior cortical wall.

ф6.0 healing abutment

Class II CMI fixation was achieved with 1-2mm of sinus involvement. The sinus was not grafted.

The final SCRP crown was cemented on the SCRP abutment with a final resin cement.

The crown was unscrewed and polished outside the mouth.

This case presents replacement of failed implant with ф6.0*7.0mm Neobiotech S-wide EB implant on site 16. Site preparation was done with S-reamer and no grafting was conducted. Implant was placed with 1-2mm of sinus involvement and has achieved inferior cortical fixation with 45N/cm of excellent stability. Immediate loading was performed on the same day of the surgery.
