Implant placement with IS III active fixtures in the posterior mandible


Situation

A 55-year-old male Hypertension A pre-operative panoramic radiograph revealed teeth missing on #45, #46 & #47. The treatment plan was: 1) IS-III active implant installation was planned. 2) Prosthesis: 3-unit zirconia SCRP FPDs on implants #45, #46 & #47

Multiple oblique incision was performed to safe attached gingiva and minimally invasive surgery. This method helps patient's wounds heal much faster.

Enough drilling for the implant placement with the appropriate Stopper connected to the drill with irrigation (Recommended speed : 1,200rpm)

Tapping with irrigation

Recommended speed when using the Cortical tap : 50rpm

Open the sterilized package after checking the type, size and expiration date of implant specified on the label and packaging status.


Connect the Fixture Driver mounted on the Hand Piece or Torque Ratchet to the implant in a straight line.

Be careful to prevent contamination of implants from metal or saliva.

Fully insert the implant inside the bone with the torque value of 35~45Ncm by placing the implant in the pre-drilled hole and rotate the Hand Piece with 25~35rpm. Make sure not to exceed 50Ncm when placing an implant.

CMI IS-III active 4.0*10mm (Neobiotech, Korea) fixture was placed in the area of #45

CMI IS-III active 5.0*10mm (Neobiotech, Korea) fixtures were placed in the area of #46 and 47.

3 implants were placed successfully.

Healing abutments were connected to the fixtures.

Pick Cap impression copings (Neobiotech, Korea) were connected to the implants for making impression for prosthesis fabrication.

A definitive 3-unit zirconia SCRP FPD were fabricated.


SCRP prepared abutments.

The SCRP abutments were repositioned.

A definitive 3-unit zirconia SCRP FPD were fabricated on the SCRP abutments.

3-unit SCRP zirconia FPD were cemented with a final resin cement.

The prosthesis was repositioned and the screw holes were occluded by resin.
