58C00
Preoperative radiograph shows 5mm of available bone height on #16
58C02
Flap raising on site 16

58C03
Site preparation was done with Ø3.6 S-reamer at 1200rpm.

58C04
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.

58C05
Taper drill designed for S-wide implant

58C06
Site 16 was prepared to place Ø6.0*7.0mm S-wide EB implant.

58C07
ф6.0*7.0mm S-wide EB implant in place

58C08
Immediate loading was planned due to 45N/cm of excellent stability achieved in the inferior cortical wall.

58C09
ф6.0 healing abutment

58C10
Class II CMI fixation was achieved with 1-2mm of sinus involvement. The sinus was not grafted.

58C17
Try-in of the SCRP crown

58C18
External type of abutment in place

58C19
The final SCRP crown was cemented on the SCRP abutment with a final resin cement.

58C20
The crown was unscrewed and polished outside the mouth.

58C21
Occlusal view. SCRP type of final restoration was delivered one week after implant placement.

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.
