Rapid Maxillary Expansion and Early Class III Treatment: New Options using Palatal TADs


May 6, 2018 8:50am ‐ May 6, 2018 9:35am

Description

To increase skeletal maxillary advancement and to avoid the possible dental side-effect of mesial movement of the dentition protraction therapy in growing children using skeletal anchorage has recently been advocated. However, most approaches have employed at least two or more surgical miniplates, which involve invasive placement and removal procedures. Maxillary protraction is often started with a rapid maxillary expansion procedure (RME) because a proportion of Class III cases present with a narrowed maxilla and mobilisation of the midfacial sutures by RME may be beneficial and induce a greater maxillary effect. In this lecture the Hybrid Hyrax appliance and its modifications are shown, which uses two mini-implants in the anterior palate to provide sagittal skeletal anchorage for maxillary protraction and transversal skeletal anchorage for maxillary expansion.

Learning Objectives:

  • Identify the optimal insertion site in the palate.
  • Experience how palatal TADs can be employed for RME and early class III treatment.
  • Recognize how palatal TAD mechanics can be integrated in to the digital workflow (TAD insertion and CAD/CAM manufacturing of the appliance).
