The study reported an adult orthodontic case with a unilateral ankylosed upper permanent first molar. A number of complications occurred, including occlusal plane canting, dental midline deviation and asymmetric molar relationship. The case demonstrated the mechanics used to solve all the complications we met. The case also showed the phenomenon that after extraction of the ankylosed tooth, the bone remodeling mechanism of the bone in situ seemed abnormal and resulted in difficulty of protracting the tooth into the extracted site. All the above reasons, therefore, resulted in prolonged treatment time. In addition, the case also demonstrated the method we used …

Clinically, there are many ways to achieve molar distalization, such as skeletal anchorage, extraoral anchorage, sliding jig, lip bumper, and pendulum, etc. Although several methods have been described to distalize molars or total dentition, there is no strong scientific evidence of the effectiveness of various methods. To date, temporary anchorage devices (TADs) are increasingly used as orthodontic anchorage sources because of its strong anchorage, including endoosseous implants, miniplates, miniscrews and microscrews. Application of bony anchorage makes teeth move more efficiently, without depending on patient compliance in wearing appliance. However, only case reports and small case series have been published on …

Dental Pulp Response To Orthodontic Tooth Movement, Chih-Wei Wang, Kai-Long Wang, Kwok-Hing Ho, Shun-Chu Hsieh, Heng-Ming Chang
Taiwanese Journal of Orthodontics
Pulp vitality may occasionally change while tooth experiencing orthodontic movement, and orthodontists are the particular group who concern this phenomenon if it happens. The respiration rate of dental pulp will be depressed inevitably in short term when tooth is subject to orthodontic force. If force level is extreme, circulatory interruption can occur and further induce pulp necrosis. When orthodontic movement on pulpalcompromised teeth (e.g. teeth with trauma history or large restorations) is required, the pulp response to orthodontic force should be monitored. This article provides an overall review on the pulpal reactions during orthodontic movement and dental movement on teeth …

A 20-year-old young male complained of his protrusive and deviated chin. He also presented occlusal plane cant, anterior open bite and unrestorable maxillary right first molar and mandibular left first molar. The severe maxilla-mandibular discrepancy was solved with surgery-first double jaw orthognathic surgery. The space of two extracted first molars was closed by protraction of the second and third molars after surgery. Two protraction techniques were used in this case, including closing maxillary right first molar space with reciprocal retraction, and closing mandibular left first molar with one miniscrew as an absolute anchorage. Careful biomechanical consideration was used during protraction …

Taiwanese Journal of Orthodontics
The obstructive sleep apnea–hypopnea syndrome (OSAHS) is a common sleep-related breathing disorder characterized by repetitive obstructions of the upper airway during sleep. Nasal continuous positive airway pressure (CPAP) is the primary choice of treatment for OSAHS, but many patients are unable or unwilling to comply with the treatment. The modification of pharyngeal patency by oral appliances (OA) is an alternative treatment for OSAHS. This article provides a brief review and information of the oral appliance application in treating OSAHS.

Camouflage Treatment In Adult Patient With Mandibular Lateral Displacement, Transverse Deficiency And Facial Asymmetry – A Case Report, Yu-Ling Tsai, Chun-Liang Kuo, I-Hua Liu
Taiwanese Journal of Orthodontics
Facial asymmetry is common in humans. Significant facial asymmetry causes both functional as well as esthetic problems. The etiologies of facial asymmetry include congenital disorders, acquired diseases, and traumatic and developmental deformities. The causes of many cases of developmental facial asymmetry are indistinct. The principle of facial asymmetry management would be correcting the underlying disorder. Orthognathic surgery is the first and better choice if face correction is the primary consideration. Camouflage orthodontic treatment was a non-invasive option for mild to moderate severity of asymmetry. We present a case with mandibular lateral displacement, transverse deficiency and facial asymmetry in a 19-year-old …
