Pre made provisional

Categories ; Posterior, flapless, immediate load, CBCT, Implant Direct

Sagittal cut of stone cast.

2

Denture tooth wax - up

3

CBCT with VPS impression worn during scan. VPS is radio opaque so the soft tissues are imaged also

4

Bone availability based on CBCT data transfer

5

BLP ( Bucco Lingual Positioner) locks in BL axis and top of the implant, for screw retained crown.

6

Narrow Diameter Buccal wing. Limited MD space between teeth. Reversible connection via hot glue.

7

Wings are permanently connected to vacuform carrier, crossbar is removed

8

RIRâ&#x20AC;&#x2122;s overlap, X-ray is diagnostic. No need for correction, so green 0 degree rotation-block

9

Model surgery in preparation for fabrication of provisional

10

Small hole enlarged for analog placement

11

Provisional composite used to cement analog into cast

12

Guided implant carrier and implant analog placed back into surgical guide

13

Analog is cemented with composite

14

Analog now in place of planned implant allowing pre-fabrication of provisional

15

Teflon tape used to separate during fabrication of provisional

16

Screw retained premade provisional

17

18

Under contoured emergence profile

19

Guide in place without rotation-block

20

Mark on rotation-block to indicate position of tri lobe for pre-made provisional

21

.

22

Implant is 4.3 mm , diameter of rotation-block is 4.1 mm, so stack

23

Tissue punch

24

Guided start-drill

25

Drill sequence

26

Intra operative radiograph

27

Guided screw tap from Nobel Biocare although Implant direct implant

28

Stack assembly

29

Once implant is a few turns in the osteotomy , snap in rotation-block, for guided implant placement

30

Matching tri-lobe to mark on rotation-block to allow provisional placement in predetermined position

31
