Temporary anchorage devices (TADs)are common used in orthodontic treatment for anchorage and force application. They have many advantages, including small size for insertion, potential for immediate loading, no need of patients’ compliance. The success rate of miniscrews was more than 80%. There are several factor affecting stability of TADs, including: insertion torque, soft tissue condition and bone quality of insertion area, magnitude and direction of orthodontic force, oral hygiene condition and insertion method. There are many different shapes, materials and types of miniscrews. Different types of TADs may have different mechanical properties and result in different success rate. We discussed …

The etiologies of skeletal Class III malocclusion include excessive growth of the mandible, insufficient growth of the maxilla, or the combination of both. The ideal treatment for severe mandibular prognathism is a combination of orthodontic treatment with orthognathic surgery to setback the mandible. However, nonsurgical approach using mini-implant anchorage could distalize the mandibular dentition and improve the occlusion if the skeletal discrepancy is mild to moderate. In this report, we present the treatment of a 20-year-old male patient with Class III malocclusion and anterior crossbite. Mini-plates were implanted on anterior border of mandibular ramus and used as temporary anchorage devices …
Treatment Of Class Ii Division 1 Malocclusion With High Mandibular Plane Angle By Miniscrews – A Case Report, Hsin-Lan Shen, Eric Jein-Wein Liou

This 16-year-old female presents with Class II Division 1 subdivision right malocclusion, complicated by gummy smile, large mandibular plane angle and the mandibular right first molar missing. Treatment consisted of 4 temporary anchorage devices (TADs) application and extraction of bilateral maxillary first premolars and the mandibular left first premolar. Bimaxillary anterior and posterior teeth were intruded by miniscrews for counterclockwise rotation of the mandible. A very favorable result was achieved due to reduction of gingival display and the mandibular plane angle was decreased successfully.

Skeletal Class III with anterior open bite is one of the most challenging problems that orthodontists may encounter. Treatment modalities for skeletal openbite malocclusion include growth modification and surgicalorthodontic therapy; which treatment is chosen depends on the patient’s age and growth potential. Treatment considerations should focus on the patient’s facial profile, skeletal pattern, growth potential, and severity of dental malocclusion. Here, we present the nonsurgical orthodontic treatment of an adult patient with anterior openbite and high-angle skeletal Class III facial pattern. The soft tissue problems associated with anterior openbite included lip incompetency and tongue thrusting habit. We corrected the dental …
