Severe Anterior Open-Bite Case Treated Using Miniscrew Anchorage: A Case Report
نویسنده
چکیده
Downward and backward rotation of the mandible and/or excessive eruption of posterior teeth often cause anterior open bite. Depending on the severity of the case, orthognathic surgery is often the treatment of choice due to the difficulty of establishing absolute anchorage of molars by using a traditional orthodontic mechanics. This article reports the successful treatment of a severe skeletal anterior open-bite case using titanium screw anchorage in a 44 years 4 months female patient with 7.0 mm anterior open bite and increased facial height. The titanium screws were implanted in both the buccal and palatal area of the maxilla, and an intrusion force was provided via elastic chains for 13 months. After active treatment of 19 months, her upper first molars were intruded 3.0 mm on each side and good occlusion was achieved. Her retrognathic chin and convex profiles were improved by an upward rotation of the mandible. The results suggest that titanium screws can be considered useful for intrusion of molars in selected anterior open-bite cases. [Fahad Alsulaimani.
