Extraction treatment using Invisalign Technique.

The Invisalign method is gaining an increasing interest as an alternative treatment option in adult patients and in difficult orthodontic cases. The aim of this work is to show a class II malocclusion with severe crowding in the upper and lower arches treated with the extraction of the upper first premolars performed by means of Invisalign. The alignment phase was successfully completed but the space closure achieved with crown tipping and without correct root inclination making a further fixed appliance phase necessary.

The use of titanium miniscrews for molar protraction in extraction treatment.

Orthodontic space closure in the mandibular arch by protraction of the mandibular second molars, after the extraction of first molars, may sometimes result in loss of incisor anchorage when using conventional orthodontic procedures. The introduction of miniscrews for immediate loading as orthodontic anchorage, has enlarged treatment possibilities. The authors illustrate their clinical experience in an adult patient treated with the extraction of mandibular first molars and the protraction of second and third molars into the extraction sites. Anchorage control was achieved with the surgical insertion of titanium miniscrews for immediate loading in the cortical bone distal to second bicuspids. Space closure was achieved by means of sliding mechanics according to Bidimensional Technique. The position of lower incisors was maintained preventing any detrimental facial effect.

Extraction treatment using a palatal implant for anchorage.

AIM: To describe the use of Straumann Orthosystem implants for orthodontic anchorage. METHODS: The Straumann Orthosystem consists of a titanium palatal implant and connected device, which can be used when absolute anchorage is required. In the present study the implant was placed in the midline at the junction of the alveolar process and hard palate. The implant was osseointegrated 13 weeks after placement. A palatal arch attached to the implant and upper first molar bands was used to provide stationary anchorage in a 23 year-old female with protruding upper anterior teeth and moderate crowding of both arches. CONCLUSION: A palatal implant provides stationary anchorage for retraction of anterior maxillary teeth.
