Aspects of the use of endosseous palatal implants in orthodontic therapy.
Control of anchorage is one of the fundamental aspects in orthodontics and dentofacial orthopedics. Osseointegrated implants provide such an anchorage in a reliable fashion, as has been demonstrated in orthodontic use of dental implants inserted for prosthetic reasons. More recently, special implants have been introduced that serve as temporary anchorage in orthodontics. One example is the Straumann Orthosystem (Institut Straumann AG, Waldenburg, Switzerland), which is inserted in the midsagittal area of the palate. Owing to the reduced bone height available in the palate, only short implants should be considered; surface enlargement by texturing and the achievement of good primary stability are prerequisite for success. The use of a palatal implant provides a continuous stable anchorage for patients with compromised periodontal anchorage potential, as well as in cases in which compliance is not dependable or cases with esthetic considerations in which the use of extraoral anchorage aids or Class II elastics may be problematic. Minimal stress on the patient, combined with maximal anchorage, distinguishes this promising new treatment modality for the orthodontist cooperating with an oral surgeon. The treatment concept is well aligned with the emphasized need for integral treatment in dentistry, especially of the adult patient.
