Full mouth implant rehabilitation of patients with severely atrophic maxilla: Quad zygomatic implants approach

Severe atrophy of the maxilla can be due to various factors such as tumor resection, generalized aggressive periodontitis, genetic disorders or syndromes. Fabrication of a prosthesis with adequate retention and stability for patients with an atrophic edentulous maxilla presents a significant challenge. Treatment concepts with zygomatic implants have evolved as an alternative for bone augmentation procedures. This review describes the restoration of the maxillary dentition using four zygomatic implants (quad zygomatic implant technique). Within the limitations of this observation, we can state that full mouth rehabilitation with quadruple zygomatic implant technique can definitely be considered as a viable treatment option treating patients with atrophic maxillae. However, studies with more follow-up time and controlled clinical trials should be done in order to document the longevity of this treatment modality.
