30 March 2021

Presented by: Guy McLellan
Host: David Veige
Date: 30 March 2021
Time: 19:00

Treating the severely atrophic maxilla has long been considered the remit of maxillofacial surgeons with extensive bone/iliac crest grafting, requiring hospital admission, lengthy recovery and extended treatment times. This has understandably led to poor patient uptake of these complex procedures.

The zygomatic implant offers a treatment alternative to major grafting, which can be carried out in the practice setting under local anaesthetic and conscious sedation. The high stability achieved with this implant allows for immediate loading. The zygomatic implant can be combined with either anterior axial implants or for severely atrophic, with two zygomatic implants each side (Quad zygoma).

Learning Objectives

You will learn about the following:

  • Classification of atrophic maxilla
  • Treatment alternatives for the atrophic maxilla
  • Major grafting procedures with clinical cases, including complications
  • The zygoma implant including indications, planning, use of stereolithographic models, technique and recent advances
  • Use of the zygoma implant as a “rescue implant” for failing implants
