REHABILITATION WITH CALVARIAL BONE-GRAFTS AND OSSEOINTEGRATED IMPLANTS AFTER PARTIAL MAXILLARY RESECTION - A CLINICAL REPORT

Osseointegrated implants can be positioned on the nondefect side of a midline maxillary resection if there is sufficient residual bone. Axial loading of the implants is difficult because the axis of rotation for an obturator prosthesis is located along the palatal margin of the defect. Rotation of the prosthesis due to a class I lever will encourage stresses within the implants and the bone surrounding the implants on the nondefect side, and this may be detrimental. Placement of implants within the defect will prevent rotation of the prosthesis and encourage axial loading of the implants. © 1992 The Editorial Council of The Journal of Prosthetic Dentistry.
