Anterior cross bite is not rare and is one of the characteristics of class III malocclusion. The prevalence rate is about 4-14% in Chinese children. Rapid Maxillary Expander (RME) has been successfully used for many years because it is not only used for correction of vertical, transverse and sagittal dimension of maxilla but also exert on reduction in nasal airway resistance. A 10 years 4 months old Chinese girl came with a chief complaint of anterior cross-bite and severe crowding. She had allergy history with nasal congestion. Complete anterior crossbite and mid-face deficiency with severe dento-alveolar discrepancy on upper arch …

Taiwanese Journal of Orthodontics
Treatment duration is one of the major determinants for patients receiving orthodontic treatment. To avoid long treatment time, orthodontists have to design sound mechanics meeting the anchorage demands and delivering appropriate force system to the tooth and its supporting tissues. However, the more crucial factors related to the treatment efficiency may lie in the individual biological response which is still largely unknown, to the force system which orthodontists regularly delivered. Low level laser with specific power setting has been shown as a non-invasive adjunctive treatment without obvious side effect for facilitating orthodontic movement in some clinical studies.

Taiwanese Journal of Orthodontics
How to accelerate orthodontic tooth movement has been an interesting issue to orthodontists and researchers. Ways being proposed to accelerate orthodontic tooth movement (OTM) include medication, mechanical stimulation, low level laser, corticotomy, periodontal accelerated osteogenic orthodontics, and surgery-first orthognathic surgery. Those invasive surgical procedures are used successfully on orthodontic patients for acceleration of OTM. Other non-invasive procedures, though with promising results obtained from animal experiments, await further clinical confirmations. This article reviewed recent clinical and animal studies, and the mechanism of medication, mechanical stimulation and surgical approaches for their effectiveness on OTM.

At present, even if the orthognathic surgical procedure had been improved and the acceptance of surgery increased, the patients and dentists could not be satisfied with simply the recovery of masticatory function. Facial esthetics has become a marked issue. However, everything has its own limitation. There is no single treatment could fulfill all the facial esthetics requirements, not even the orthognathic surgery. If the orthognathic surgery could be combined with other cosmetic surgical procedure, the patients would be more likely to receive relatively compre-hensive treatment. First, this article reviewed the fundamental definition of facial esthetic in psychology. In addition, we …

Elastomeric chains were introduced to the orthodontic profession in the 1960s’, and are now an integral part of every day practices. They are used to generate light continuous forces for correcting rotations, consolidating spaces, and retraction canines. They are inexpensive, easily applied, relatively hygienic and require little or no patient cooperation. Elastomeric chain, however, are nor without their disadvantages. When exposed to an oral environment, they absorb water and saliva, permanent stain, and suffer breakdown of internal binds leading to permanent deformation. They also experience rapid loss of force due to stress relaxation, resulting in a gradual loss of effectiveness. …

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 …

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 …
