Rehabilitation of edentulous maxillary arch with implant-assisted fixed complete prosthesis using multi-unit straight and angulated abutments

In comparison to an edentate mandible, rehabilitation of a completely edentulous maxilla using osseointegrated implants has always tested the ability of clinician and laboratory technician. Complex anatomy, as well as the biomechanical limitations of the maxillary bone, resists the placement of implant in its ideal location. This article illustrates a two-stage surgical and prosthetic management of edentulous maxilla opposing natural teeth using seven implants. This case report highlights the advantages of multi-unit straight and angulated abutments, torqued onto the implants, over which a cast titanium framework was made for fabrication of implant-assisted fixed complete dental prosthesis (FP-3 prostheses).
