Title of Talk

Think the indications for orthodontic miniplates over again


As temporary skeletal anchorage devices were being developed in the 1990s, 2 types were widely put into use. There were great expectations for those that could ossointegrate with bone. This type included retromolar implants, palatal implants, and mini-implants. The other type, developing in parallel, was the mechanical retention type and included miniplates and miniscrews. Extensive clinical experience for a wide range of orthodontic problems and detailed evaluations of these modalities over the years have brought us to where we are now: the temporary skeletal anchorage devices in use are miniplates and miniscrews, and both offer mechanical retention. These 2 types of devices actually function best when they are working in collaboration with each other. Although miniscrews have a valuable role in modern orthodontics, the focus of this presentation will be on recent indications for miniplates; those are 1) backup system of miniscrews, 2) difficult cases with complex orthodontic problems, 3) surgical orthodontics and 4) orthopedic treatment.
