Lip Canting Correction In Patients With Facial Asymmetry After Orthognathic Surgery, Pr Wu, Sc Chen, Tf Chen, Ty Wu
Taiwanese Journal of Orthodontics
Patients with facial asymmetry usually accompany with lip canting. Most of these patients came for orthognathic surgery combine orthodontic treatment for chin deviation and asymmetric facial problem. However, the improvement of lip canting after surgery is not as predictable as correction of chin deviation. From our literature review, the correlated factors of lip canting were discussed, and the relationship between improvement of lip canting with two jaw/ one jaw orthognathic surgery were reviewed.

The digital dental models are not subject to physical damage, and require negligible storage space. They can be transferred electronically to specialists easily and can be carried out with virtual setups. A precision 3-dimensional head model can be fabricated by integrating a digital dental model into a maxillofacial 3-D CT image. Using this 3-D image, it is possible to perform dental decompensation, reposition of osteotomized bony structures, and simulate the postoperative results on hard and soft tissue in 3-D on our computer screen. Besides, it also spares the laboratory time with CAD/CAM surgical splint manufactured.

Surgical Orthodontic Correction Of Class Iii Malocclusion With Anterior Openbite - A Case Report, Yi-Jen Liu, Ya-Wen Wang, Wen-Pei Wong, Min-Chih Hung, Chung-Chen Jane Yao, Yi-Jane Chen
Taiwanese Journal of Orthodontics
The etiologies of skeletal Class III malocclusion include excessive growth of mandible, deficient growth of maxilla, and the combination of both. Anterior openbite may be due to skeletal, dental, habitual, or functional problems. Mini-implant can be a reliable anchorage for maxillary molar intrusion, which facilitate anterior openbite closure by counterclockwise rotation of the mandible. However, the mandibular counterclockwise rotation may increase antero-posterior jaw discrepancy in Class III malocclusion. Therefore, surgical orthodontics is often required in the treatment of Class III malocclusion with anterior openbite. In this report, we present the treatment of an adult Class III patient with mandibular prognathism, …

Taiwanese Journal of Orthodontics
Facial asymmetry affects more frequently on the lower face than the upper face. Significant facial asymmetry compromises both occlusal function and facial esthetics. The etiology of facial asymmetry may be skeletal, dental, and soft tissue components of dentofacial structures. Correct diagnosis and appropriate treatment planning are very important in the management of the orthodontic patients with the chief complaint of facial asymmetry. Facial asymmetry in lower face can be clearly detected through the examination on chin deviation and asymmetry of bilateral gonial angle regions. The amount and the direction of deviation usually reveals the dental compensation in the transverse aspect …

Taiwanese Journal of Orthodontics
In order to achieve better facial esthetics, functional occlusion, maintaining tissue health and stable treatment results, orthognathic surgery is required in certain orthodontic patients. While planning orthognathic surgery, we should inform patients benefits and risks associated in this treatment modality. Possible side effects including the post-operational temporary physiological influences to the patient should be mentioned.Thus, patients will be less anxious and deal with those problems more comfortably. The most common post-operation influences of orthognathic surgery is hypomobility. The objective measurements for mandibular function are maximum mouth opening (MMO), maximum bite force, and muscle fatigability. We summarize and compare the literatures …

Surgical Orthodontic Treatment For A Class Iii Patient With Anterior Openbite And Multiple Idiopathic Root Resorption – A Case Report, Shao-Chun Lu, Shu-Yin Chao, Yao-Der Huang, Sang-Heng Kok, Yi-Jane Chen
Taiwanese Journal of Orthodontics
Severe root resorption with excessive tooth mobility may compromise the capability of the teeth to sustain occlusal loading, and possibly lead to extraction. Apical external root resorption (AERR) is considered as one of the risks associated with orthodontic treatment. Some clinical factors have been shown to correlate with orthodontic treatment, whereas the determinants for predicting AERR consistently were not found. Therefore, orthodontists must monitor the amount of root resorption during the course of orthodontic treatment. Multiple idiopathic root resorption (MIRR) is a rare condition. If MIRR is present, the severity of tooth mobility may get worsen during orthodontic treatment. The …

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 …
