First Clinical Visit:    


1. Pre-operative radiograph.


2. View of pre-operative site.


3. Osteotomy being enlarged with a teal 3.0mm latch reamer rotating at 50 RPM without water irrigation after the initial osteotomy was made with the 2mm pilot bur.


4. Osteotomy being enlarged with a red 4.0mm hand reamer rotating at 50 RPM without water irrigation.


5. Bone depth gauge being used to measure the depth of the osteotomy.


6. A 4.5mm x 6.0mm HA coated implant being inserted into the osteotomy with an implant seating tip threaded onto a straight driver.


7. Harvested bone being placed over the shoulder of the implant.


8. Trimmed polyethylene healing plug being inserted into the seated implant.


9. Post operative radiograph.
Second Clinical Visit:    


10. Bonded prosthesis prior to its removal for the making of implant level transfer impression.


11. View of operative site prior to the making of an implant level transfer impression.


12. View of the trimmed black polyethylene plug seated in the well of the implant.


13. Healing plug being removed with a healing plug removal instrument.


14. Impression reamer being rotated on guide pin to remove any tissue which might inhibit the complete seating of an impression post.


15. Green 3.0mm plastic impression post being inserted into the 3.0mm well of an integrated implant for the making of an implant level transfer impression.


16. Green 3.0mm plastic impression post receiving its mandatory seating tap.


17. Impression material being injected around impression post for the making of a full arch implant level transfer impression.
