Microimplant screws for Anchorage


Friends,

MIA is an extremely valuable modality. It helps in your routine treatment and also enables to treat those difficult cases that we thought not treatable by orthodontics. It also improves outcomes in many cases and cuts treatment time. Long ago we had posted several cases on www.healthmantra.com/ic/ , one case was of correction of anterior cant of occlusion

Now there is a wonderful article on correction of post cant by use of MIA, it is in Aug issue of AJODO. here is the abstract and one pic

Introduction: Facial asymmetry is a major complaint of orthodontic patients. In those with severe facial asymmetry, combination treatment of LeFort I osteotomy and mandibular surgery was commonly used. This article demonstrates the usefulness of titanium screws for orthodontic anchorage to intrude the molars in 2 patients with facial asymmetry and canted occlusal plane. Methods and Results: The first patient was a woman, aged 29 years 6 months, with mandibular protrusion and canted occlusal plane; she was treated with molar intrusion and intraoral vertical ramus osteotomy. During presurgical orthodontic treatment, a titanium
screw was implanted in the zygomatic process, and the molars were intruded for 6 months by using an elastic chain of 200 g. After intrusion, the molars were intruded 3.0 mm, and the canted maxillary occlusal plane was improved. The second patient was a young man, aged 16 years 5 months, with mandibular deviation and canted occlusal plane; he was treated with a combination of titanium screw anchorage and intraoral vertical ramus osteotomy. A miniscrew was implanted in the alveolar bone, and the orthodontic load began immediately after placement surgery by using an elastic chain. After 5 months of intrusion, the molars
had been intruded by 3.0 mm. Conclusions: Compared with 2-jaw surgery, this method of molar intrusion is less invasive, involves less psychological stress, is less expensive, and results in less postoperative discomfort. Therefore, treatment with titanium screws for molar intrusion to correct a canted occlusal plane could become a new treatment strategy for patients with facial asymmetry.
