Severe Maxillary Atrophy Management – Quad Zygoma Surgical Technique

This clinical case presentation demonstrates management of severe maxillary atrophy using a quad zygoma surgical technique for full-arch implant rehabilitation. Preoperative facial, lateral profile, and CT scan evaluations revealed severe maxillary deficiency requiring advanced zygomatic implant reconstruction. Final postoperative images demonstrated improved facial support, esthetics, and successful full-arch implant rehabilitation.

The presentation documents comprehensive treatment of a female patient with severe maxillary atrophy and compromised maxillary support requiring advanced implant rehabilitation. Initial facial and lateral profile photographs demonstrated loss of upper lip support, maxillary deficiency, and esthetic collapse associated with advanced maxillary resorption.

Preoperative CT scans revealed extensive maxillary bone loss with insufficient alveolar bone volume for conventional implant placement. Measurements shown on CT imaging demonstrated limited residual maxillary dimensions requiring alternative anchorage strategies.

The surgical management phase involved:

  • Exposure of severely atrophic maxillary anatomy
  • Full-arch surgical access
  • Placement of quad zygomatic implants
  • Advanced zygoma-based anchorage techniques for maxillary reconstruction

Intraoperative photographs labeled “Severe Maxillary Atrophy Management” and “Quad Zygoma Surgical Technique” documented implant osteotomy preparation and placement within the zygomatic buttress regions.

Comparative postoperative CT scans demonstrated successful implant positioning and reconstruction of the maxillary arch. Final clinical photographs showed:

  • Improved facial esthetics
  • Enhanced lip support
  • Improved smile appearance
  • Functional full-arch implant rehabilitation
  • Restored facial profile contours

The completed case highlighted the effectiveness of quad zygoma reconstruction in patients with severe maxillary atrophy unsuitable for conventional implant therapy.
