The quality of maxillary bone is generally lower than that of mandibular bone; consequently,
complete arch immediate implant-loading treatment is not as predictable in the maxillary as in the
mandibular arch. The All-on-4 concept has proven to be an effective and successful treatment
protocol. However, the survival rate of All-on-4 implants in the maxilla is lower than of those in the
mandible. In this report, 2 anterior wide-diameter implants were used with the All-on-4 concept for
a maxillary rehabilitation to provide biomechanical benefits with better primary stability while
still achieving a functional and esthetic result. The clinical challenges of using wide-diameter implants
in the anterior region are also discussed and should be considered during treatment
planning. (J Prosthet Dent 2016;116:483-487)
