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.


슬라이드8
Enough drilling for the implant placement with the appropriate Stopper connected to the drill with irrigation (Recommended speed : 1,200rpm)

슬라이드9
Tapping with irrigation

슬라이드10
Recommended speed when using the Cortical tap : 50rpm

슬라이드11
Open the sterilized package after checking the type, size and expiration date of implant specified on the label and packaging status.

슬라이드12


슬라이드13
Connect the Fixture Driver mounted on the Hand Piece or Torque Ratchet to the implant in a straight line.

슬라이드14
Be careful to prevent contamination of implants from metal or saliva.

슬라이드15
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

슬라이드17
CMI IS-III active 5.0*10mm (Neobiotech, Korea) fixtures were placed in the area of #46 and 47.

슬라이드18
3 implants were placed successfully.

슬라이드19
Healing abutments were connected to the fixtures.

슬라이드22
Postoperative panoramic radiograph showing 3 implants placed in the mandibular right posterior area.

4 weeks after the surgery.

슬라이드21
3 months after implant placement surgery.
Good soft tissue healing was seen. Impression was made at this time.


슬라이드23
A periapical radiograph after 3 months healing.

슬라이드24
Pick Cap impression copings (Neobiotech, Korea) were connected to the implants for making impression for prosthesis fabrication.

슬라이드25
A definitive 3-unit zirconia SCRP FPD were fabricated.

슬라이드27


슬라이드28
SCRP prepared abutments.

슬라이드29
The SCRP abutments were repositioned.

슬라이드30
A definitive 3-unit zirconia SCRP FPD were fabricated on the SCRP abutments.

슬라이드31
3-unit SCRP zirconia FPD were cemented with a final resin cement.

슬라이드33
The prosthesis was repositioned and the screw holes were occluded by resin.
