Conclusions
The zygomatic implant – the zygomaticus fixture – appears to be a promising development in implant technology. It offers an interesting alternative solution to complex bone grafting in the severely resorbed posterior maxilla. The combination of a regular implant, Zygomatic and pterygoid gives us an excellent torque for immediate loading, giving back the masticatory function to the patient.
Moreover, this technique enhances the psychological and the esthetic outcomes.
