Pterygoid extension with

palatal struts endosteal righ and left

In this somewhat unusual old pterygoid extension case, one posterior abutment is a natural tooth—the only tooth remaining in the arch (I). The large torus and uneven ridge resorption were also noteworthy in this case, forcing unusual, unbalanced placement of the blodevents (2). The pterygoid extension implant, and older design (3,4), covered a good portion of the palate, requiring extensive exposure (5) of the palatal surface for seating the implant. The tissues were closed under the bar (6), and allowed to heal (7). The clip-on denture (8), without a bothersome palatal portion (9), attaches to the bar.
