Immediate Stabilization and Function / Polyceramic Material Fused to Metal: Extraction, Placement and Restoration of Four Mandibular Incisors with Two Immediately Functioning Implants and a four-unit polyceramic material to metal fixed prosthesis
This case demonstrates the extraction of four mandibular incisors and the immediate placement of two immediately functioning implants and their restoration with a four-unit polyceramic material to metal fixed prosthesis.

 

    


1. Pre-operative radiograph.


2. Pre-operative site.


3. Extraction of failed endodontically treated tooth.


4. Extraction of failed endodontically treated tooth.


5. Soft tissue being removed from the five walls of the extraction sockets.


6. Osteotomy being prepared with 2.0mm pilot bur rotating at 1100RPM with external irrigation.


7. Parallel pin confirming appropriate trajectory and acting as a guide for subsequent osteotomy.


8. Latch reamer extension being used to facilitate the use of the pilot bur close to the adjacent canine tooth.


9. Parallel pins seated in their pilot osteotomies indicating their trajectories.


10. A 2.0mm guidepin being inserted into the pilot osteotomy to accommodate using a sulcus reamer as a planisher to level the crestal bone around the pilot osteotomy.


11. Sulcus reamer being inserted onto the guide pin.


12. Sulcus reamer being used to level the bone heights around the pilot osteotomy, since uneven levels may cause inadvertent displacement of the reamer burs.


13. Osteotomy being enlarged with an olive green 2.5mm latch reamer bur rotating at 50RPM without water irrigation.


14. Depth gauge confirming the appropriateness of the prepared osteotomy


15. 3.5mm x 11.0mm HA coated implant with a 2.0mm implant well is being inserted with the black polyethylene healing plug.
