Zygomatic fixtures--the Sydney experience.

A R Stevenson, B W Austin

    Annals of the Royal Australasian College of Dental Surgeons
    |November 17, 2001

    Summary

    Zygomatic implants combined with standard implants offer a faster, less invasive solution for patients with an atrophic maxilla needing fixed dental restorations. This technique avoids extensive bone grafting, improving patient outcomes.

    Area of Science:

    • Oral and Maxillofacial Surgery
    • Restorative Dentistry
    • Dental Implantology

    Background:

    • Atrophic maxilla presents significant challenges for full denture stability and implant-supported restorations.
    • Traditional bone grafting for dental implants is invasive and not suitable for all patients.
    • Osseointegrated dental implants are a viable solution but often require extensive bone augmentation in atrophic maxillae.

    Purpose of the Study:

    • To evaluate the efficacy of combining zygomatic fixtures with conventional implants in the anterior maxilla for fixed restorations.
    • To offer a less morbid and time-efficient treatment alternative to bone grafting for patients with severe maxillary atrophy.
    • To present clinical outcomes for patients treated with this hybrid implant approach.

    Main Methods:

    • Placement of zygomatic implants anchored in the zygoma.
    • Simultaneous or sequential placement of conventional implants in the anterior maxilla.
    • Restoration with a fixed maxillary prosthesis.
    • Evaluation of treatment time, morbidity, and prosthetic stability.

    Main Results:

    • Successful prosthetic rehabilitation was achieved in all five patients.
    • The combined technique allowed for shorter treatment duration compared to traditional grafting procedures.
    • Patients experienced reduced surgical morbidity.
    • Stable and retentive fixed restorations were provided.

    Conclusions:

    • The combination of zygomatic implants and anterior maxilla implants is a viable and effective treatment for patients with severe maxillary atrophy.
    • This approach significantly reduces treatment time and patient morbidity.
    • It provides a stable, fixed prosthetic solution, overcoming the limitations of conventional dentures and extensive grafting.
