Telescopic Restoration: Telescopic Restoration Technique
The telescopic or sleeve overdenture restoration is an excellent alternative to extensive cortical bone grafting, that is often necessary for the treatment of atrophic alveolar ridges. Although it is a removable prosthesis, the patient perceives that the overdenture has the stability of a fixed prosthesis. Three implants placed bilaterally is the ideal support for this prosthesis. Straight and angled solid core Bicon abutments with 360° of universal positioning not only facilitate the fabrication but also enhance the possibility for exceptional aesthetics with the telescopic restoration because the abutment itself can act as the primary crown. Although the positioning of the abutments in the following clinical case is not typical of a telescopic restoration, the depicted techniques are demonstrative.

     


1. Occlusal registration plate.


2. Recording preliminary occclusal relationships.


3. Black plastic impression post being inserted into 2.0mm implant well.


4. Black impression post being tapped into 2.0mm implant well.


5. Impression material being injected around impression post for the making of implant level transfer impression.


6. Black impression post and metal implant analog.


7. Plastic impression post and metal implant analog being inserted as a unit into transfer impression.


8. Transfer impression prior to the pouring of a stone model.


9. A milled abutment being prepared with a 3.0mm long 2° cervical taper.


10. Milled abutments on master stone model.


11. Six individual metal copings seated on milled abutments.


12. Metal horseshoe shaped strut.


13. Horseshoe shaped strut on metal copings.


14. Yellow plastic orientation jig facilitating the initial insertion of a milled abutment.


15. Plastic jig facilitating the insertion of a second milled abutment.


16. Abutment being tapped for a definitive seating into the implant.


17. Orientation jig being removed.


18. Six definitively seated milled abutments.


19. Six individual copings seated on milled abutments.


20. Horseshoe shaped strut seated on individual copings.


21. Red acrylic resin being injected in horseshoe shaped strut.


22. Horseshoe shaped strut being affixed to six individual copings.


23. Impression material being injected around copings and affixed strut for their withdrawal in a transfer impression.


24. Occlusal registrations being made over seated abutments.


25. New master model on which the soldered copings and horseshoe shaped strut will be processed into the final prosthesis.


26. Final prosthesis on model.


27. Final prosthesis on model.

31. Milled abutment being inserted into prosthesis to facilitate its orientation into the well of its implant.


32. Prosthesis being inserted as an orientation jig for the seating of a milled abutment.


33. Yellow plastic orientation jig confirming the accuracy of the abutment placements.


34. Tapping of the milled abutment into the well of the implant.


35. Abutment being tapped definitively into its implant.


36. Definitively seated abutments.


37. Telescopic overdenture being inserted.


38. Telescopic overdenture being inserted.


39. Occlusal contacts being confirmed.
