Distraction osteogenesis (DO) is a surgical procedure that uses a distractor through an osteotomy site, by applying mechanical stretching forces to produce new organization. These organizations contain skeleton, muscles, nerves, blood vessels and so on. This article reviewed the comparisons of DO with conventional guided bone regeneration (GBR) and conventional orthognathic surgery (OGS), as well as the introduction of some of the recent case reports, clinical studies and post-surgery stability in relation to the dentoalveolus, maxilla and mandible regions. The success of DO is mainly related to the surgical treatment plan and the techniques. Same as the OGS, pre-surgical DO …

Application Of Miniscrew Anchorage To Assist Scissors-Bite Correction, Ting-Ting Wu, Ellen Wen-Ching Ko
Taiwanese Journal of Orthodontics
Posterior complete buccal crossbite, also called scissors-bite or Brodie Bite, is usually difficult to be corrected. In most cases with the occlusion of complete buccal crossbite, the mandibular teeth are lingually tilted, and the maxillary teeth erupt past their antagonists. When using the conventional orthodontic treatment to correct the scissors-bite, extrusion of the molars and subsequent occlusal plane canting frequently occur. Applying miniscrew as direct skeletal anchorage can facilitate the scissors-bite correction without totally depending on patients’ compliance. Two young female adults, with unilateral complete posterior buccal crossbite and Angle Class I malocclusion, were treated with fixed appliance, miniscrews, and …

Treatment Of Skeletal Class Iii Malocclusion With Mandibular Miniplate Skeletal Anchorage – Case Report, Yi-Shiou Chen, Jian-Shun Chen, Fong-Lan Chan, Yi-Jane Chen
Taiwanese Journal of Orthodontics
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 …

Periodontal accelerated osteogenic orthodontics (PAOO) is a clinical procedure that combines selective alveolar corticotomy, particulate bone grafting, and the application of orthodontic forces. This procedure is theoretically based on the bone healing pattern known as the regional acceleratory phenomenon (RAP). Recently, partial evidences supported that PAOO had some advantages: 1. Shorter treatment time; 2. An increment in alveolar bone width; 3. Decreased amount of apical root resorption; 4. Increased post-treatment stability. This article reviewed the recent case reports, clinical studies, and animal studies, and tried to introduce the development, idea, and the method of PAOO for the application of rapid …

Intrusion Of Supraerupted Maxillary Molar Using Posterior Bite Plate And Mini-Screw, Chih-Kai Huang, Chun-Liang Kuo, Yun-I Wang, I-Hua Liu
Taiwanese Journal of Orthodontics
Supraerupted maxillary molars usually result from early loss of the opposing mandible molars. This may induce insufficient intermaxillary space and compromised prosthesis. The best way to deal with supraerupted maxillary molars is no doubt to intrude them. For the minor supraeruption of maxillary molars, simply wearing a posterior bite plate could apply vertical force to intrude them. But the larger supraeruption, combination with temporary anchorage device usage will supply more stable anchorage force to intrude maxillary molars back to the normal position. This article reported three cases, one using only posterior bite plate and the others in combination with mini-screw, …

Taiwanese Journal of Orthodontics
To manage moderate mandibular prognathism combined with anterior open bite in adult cases,the dento-alveolar growth has to be guided and carefully utilized during orthodontic treatment, especially when the patients have acceptable profile before treatment and tend to deny the needs of orthognathic surgery. Two cases with similar diagnosis and treatment principle were reported. Extraction of mandibular molars provided spaces for lingual tipping movement of lower incisors, the lower occlusal plane showed a counter-clockwise rotation, the open-bite was accordingly corrected and the molar relationship was also normalized. To be able to command the occlusal plane changes is the key to archive …

Overextrusion of maxillary molars usually results from early loss of antagonistic teeth due to caries or periodontitis. Conventional techniques for molar intrusion was used multiple teeth and extraoral devices, that depended highly on patient’s cooperation and usually result in extrusion of other teeth rather than posterior intrusion. This article reviews treatment consideration, force mechanics and side effects about miniscrews for intrusion of upper molars. We also present a clinical case to confirm miniscrew treat supra-erupted upper molars successfully.

Taiwanese Journal of Orthodontics
Adult orthodontic treatment has become increasingly popular. The primary motivating factor for seeking orthodontic treatment in adults is facial and dental esthetics, especially the alignment of their anterior teeth. Pathologic migration of anterior teeth is a common cause of esthetic concern among adult patients. The anchorage control is very important in the orthodontic treatment for the dentition with compromised periodontal support. Mini-implant anchorage provides a good solution to this situation. However, the force level should be light and consistent. Herein we report a 33-year-old female patient who presented a Class II division 1 malocclusion with maxillary anterior crowding, protrusion, and …
