Implant-supported rehabilitation of the severely atrophic maxilla: a clinical report

J Prosthodont. 2004 Sep;13(3):187-91. doi: 10.1111/j.1532-849X.2004.04031.x.


Implant-supported rehabilitation in the posterior maxillary region presents a series of challenges because of the possibility of increased pneumatization of the maxillary sinus after dental loss. In cases where significant maxillary bone resorption has occurred, efforts center on maximizing the use of the remaining bone to afford primary stability to the implants. This clinical report describes a patient with extreme maxillary atrophy for whom fixed rehabilitation supported on 8 implants was accomplished. A zygomatic implant, a pterygomaxillary implant, and 2 implants mesial and distal to both canine eminences were placed. This rehabilitation was accomplished with a less invasive technique and in a much shorter time period compared to a sinus lift procedure. One year after prosthetic loading, the clinical and radiological results remain satisfactory.
