Aim: Stable anchorage for the application of orthodontic forces may help avoid unwanted movements of the anchorage teeth. The palatal implant has been shown to provide such anchorage in the maxillary arch. The aim of this clinical study was to introduce stable anchorage in the mandible. Method: After the surgical exposure of the mandibular cortical bone in the vestibule of the canine-premolar region, a T- or L-shaped osteosynthesis miniplate was adapted to the osseous surface. The vertical component was trimmed according to the occlusal level, and the plate was fixed with monocortical screws. After a soft tissue healing period of 10 days, the vertical extension of the plate was used for orthodontic force application to achieve a mesialization of the posterior dentition. Results: This technique provides rigid anchorage; there were no observable inflammatory reactions around the plate penetration areas, and any spaces after premolar extractions can be closed without unwanted side effects to the anterior teeth, normally used as anchorage. A space of up to 8 mm can be closed within 12 months of treatment. Both the insertion and the removal of the implant took place without any adverse events. Conclusion: Surgical miniplates are common in traumatology. The presented new indication for such plates offers orthodontists a stable anchorage element, localized in the mandibular vestibulum. Therefore, the name “Vestplant” characterizes the device.
