Combinations o

Blades and

Subperiosteal

In this situation all remaining teeth had to be extracted, figs. 1, 2. A partial bone impression on the left posterior quadrant was taken for a unilateral subperiosteal implant since not enough bone existed in that area for a blade. Fig. 3 shows the subperiosteal implant and the desired blades that were to be used. The subperiosteal implant is always tried in before the blades are inserted to make sure of its proper fit, fig. 4. Grooves were then made into the crestal bone for the insertion of three blades, and the tissues were sutured together, figs. 5, 6, 7, 8, 9. Soldered gold copings were fitted over the implants, fig. 10. By the fourth week, the prosthesis was ready for cementation, figs. 11, 12, 13, 14. This is an eight and one half year post operative x-ray, fig. 15.
