Clinical Advantages of Palatal Locking Plate Anchor - Multi-Center Results -


The skeletal anchorage, such as conventional dental implants, miniscrews and miniplates, have been become a great strategy in the success of orthodontic treatment. One of important requirement as the temporary skeletal anchorage devise must be excellent reliability, because the failure may cause a problem in the relationship between the patient and the orthodontist in the clinical field.
We have utilized the unique titanium locking plate and screw system as the temporary skeletal anchorage devise for the orthodontic treatment. Using double threaded screws, which lock into both the bone and the locking plate, we could fix the locking plate over the palatal mucosa (2-3 mm apart from the palatal surface), instead of the placement on the cortical bone under the mucoperioseteal incision. The mid-palatal area may be suitable for the temporary implantation for orthodontic skeletal anchorage, because of the less possibility to injure nerves, blood vessels or tooth roots. The placement over the mucosa may not only offer the less instrumentation and faster application, but also produce less inflammation with high self-purification over the keratinized attached palatal mucosa and high flexibility as the devise for the orthodontic anchorage.
In this presentation, we will discuss the high reliability of the palatal locking plate anchor with showing the results (more than 500 patients) from the different three orthodontic practices.
