Today's orthodontics has made major advances with respect to the most effective, compliance free and invisible treatment options. This leads to fast and stable results with a reduced need for extractions. A key to success is skeletal anchorage in the anterior palate, which is a safe region for placing orthodontic mini-implants. Various treatment options, but especially distalization/mesialization of buccal segment teeth and maxillary expansion are possible. In pre-adolescents and adolescents the Top Jet distalizer and the Hybrid Hyrax or the MICRO2 expander seem to complement to each other as the same orthodontic mini-implants can be used in consecutive stages of treatment. Thus more than 10 mm of space may be readily gained if needed. Thereafter these two mini-implants can then be used to attach a MICRO-transpalatal arch for retention.

The MICRO-4 or 6 expander is a pure bone-borne orthodontic mini-implant supported expander used in older adolescents and adults. More than 6 years of clinical use, in over 200 adult patients, demonstrates excellent results in maxillary expansion. In most cases surgical assisted maxillary expansion can be avoided (17-23 years 100% No-SARPE, 23-33 years 91% No-SARPE, 34-57 years 60% No-SARPE). This technique of expansion, without any loss of anchorage, improves the facial profile and smile, facilitates breathing and relieves strain in the periodontal tissues. The basis for this success is the rigid appliance construction and a polycyclic, force controlled expansion protocol.
Creating between 4-11 mm of space in the anterior mandible has become a routine procedure with the MMDO-hinge expander. This pure tooth-borne appliance does not require surgical insertion but enables strictly parallel opening of the median mandibular distraction zone, without expanding the condyles. This is combined with minimal invasive surgery.
Another compliance free orthodontic appliance, is the Sagittal Maxillary Stretch appliance that has proved very effective for compliance-free late Class III treatment and is a viable option to a protraction facemask. It is invisible, compliance free and stimulates maxillary sagittal growth.
All these appliances offer new treatment possibilities by widening the skeletal bases. Construction principles, clinical decisions and step by step handling of these appliances will be presented, together with clinical photographs showing the treatment of a variety of malocclusions.
