Zygomatic implants have been used widely to treat patients with severely resorbed maxillae. They allow implant placement to support fixed prosthetics. Guided surgical approaches are being utilized to maximize placement of the prosthetic platform of these implants. The implant team (including surgeon, prosthodontist, and laboratory technician) uses a 3-dimensional (3D) computed tomography (CT) scan, i.e, cone-beam CT (CBCT), to determine the available bone mass present in the severely resorbed maxilla, which will help dictate whether successful rehabilitation can be achieved through multiple grafting procedures, a conventional All-on-4® (Nobel Biocare, nobelbiocare.com) or similar procedure may be performed, or zygomatic implants will be required to restore the patient’s arch.
Maxillary six implants All on four implants Conventional placement of maxillary or mandibular implants to rehabilitate complete arch requires placement of bone graft to achieve stability implants. Placement of additional bone grafts require time to mature to osseointegrate with implants.
With the concept of All on four technique placement of longer implants than the conventional implants provides much more stability. Moreover, longer implants provides reduces the number of implants to be used for the final successful prosthetic outcome.
In Aesthetica (Sarat bose road), we successfully rehabilitate edentulism with zygomatic implants with successful prosthetic outcome.
