, Successful prosthetic rehabilitation of patients with extreme bone resorption in the maxilla is often compromised by the inability to obtain sufficient anchorage for the prosthesis.
Such patients seek a permanent solution that involves minimal surgical procedures and reduced treatment time, without sacrificing their expectations of success.
The development of the Zygoma implant
presents a unique alternative for rehabilitating the severely resorbed maxilla, with only one surgical procedure and without the need for grafting.
simplifies the most difficult cases, enabling implantologist to treat patients without bone grafts.
Factors to consider when planning a Zygoma-implant patient:
- Where sufficient anterior bone remains for the installation of standard implants and the posterior alveolar crest has resorbed
to such an extent, that additional implants would otherwise require the support of onlay or inlay grafts.
- Where an anterior onlay graft is required for implant placement and the need to extend the graft posteriorly can be eliminated by placing the Zygoma implant.
- The partially edentulous maxilla with uni- or bilateral loss of premolars and molars, combined with severe bone resorption. In such situations,
a Zygoma implant, in combination with at least two regular implants, will offer adequate support for a fixed restoration.
- Clinically symptom free and pathology free sinuses
- Appropriate radiographic imaging of the maxillary sinuses and zygoma regions
- Possibility of placing at least two ordinary implants in the frontal maxilla
- Possibility of controling or decreasing bending moments by cross-arch stabilization, decreased cantilevers and balanced occlusion
Patient requirements: Fixed prosthesis.
