Lip Canting Correction In Patients With Facial Asymmetry After Orthognathic Surgery, Pr Wu, Sc Chen, Tf Chen, Ty Wu
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.
Surgical-Orthodontic Correction Of Skeletal Class I Malocclusion With Facial Asymmetry: A Case Report, Kai-Wen Yu, Chi-Ying Huang, Stella Ya-Hui Yang, Yi-Jane Chen
Surgical-Orthodontic Correction Of Skeletal Class I Malocclusion With Facial Asymmetry: A Case Report, Kai-Wen Yu, Chi-Ying Huang, Stella Ya-Hui Yang, Yi-Jane Chen
Taiwanese Journal of Orthodontics
Correction of facial asymmetry is one of the most difficult challenges in orthognathic surgery. Bardinet classified facial asymmetries based on three clinical entities: mandibular lateral deviations, dental asymmetries without skeletal involvement, and skeletal asymmetries. In some cases, combinations of soft tissue deformities and skeletal discrepancies complicate treatment outcome and management. This report presents a case of a 29-year-old male with skeletal Class I malocclusion, high mandibular plane angle, facial asymmetry, and dental Class III malocclusion. Mild left-side down occlusal plane canting and chin deviation to right side was observed. The pre-surgical orthodontic treatment started with full-mouth fixed appliance therapy for …

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 …

Facial asymmetry is a common feature in orthodontic patients. Mild skeletal facial asymmetry can be treated effectively by camouflaged orthodontic technique. Orthodontic treatment combined with orthognathic surgery would be suggested in some extreme cases of facial asymmetry. Although traditional posteroanterior cephalogram was 2D image, it was still full of reference meaning and value for diagnosing the asymmetric component in craniofacial area. The objective of this research was to investigate the differences in morphological characteristics of facial asymmetry patient who can be treated by orthodontic therapy only or combined orthognathic surgery. The pre-treatment postero-anterior cephalograms of two groups of 60 subjects …
Application Of 3-Dimensional Casting Model From Ct Scan In The Orthognathic Surgery To Correct Facial Asymmetry – A Case Report., Yu-Jen Chang, Wen-Ching Tsai, Chia-Yu Wang, Wei-Yung Hsu
Application Of 3-Dimensional Casting Model From Ct Scan In The Orthognathic Surgery To Correct Facial Asymmetry – A Case Report., Yu-Jen Chang, Wen-Ching Tsai, Chia-Yu Wang, Wei-Yung Hsu

In treating patients with facial asymmetry, orthognathic surgery is often needed in combination with orthodontic treatment. Conventional surgical treatment planning uses dental casts and two-dimensional radiography to predict the amount of movement needed. However, the real movement modeled on the mounted casts on the articulator cannot be simulated accurately based on the two-dimensional radiographs. In this case report, we presented a new method using three-dimensional casting model for surgical planning and design. This case report presented an 18-year-old female (at the time of surgery), diagnosed as Class III malocclusion with facial asymmetry. The surgical plan was orthodontic treatment combined with …
Interdisciplinary Approach To Correct Mandibular Prognathism With Missing Central Incisor — Case Report, Sam Sheng-Pin Hsu, Clement Cheng-Hui Lin, Hsin-Yi Hsieh, Emma Yuh-Jia Hsieh, Chiung-Shing Huang, Eric Jein-Wein Liou, Ellen Wen-Ching Ko, Yu-Fang Liao, Yu-Ray Chen

Taiwanese Journal of Orthodontics
A case of mandibular prognathism with facial asymmetry was presented. The missing left central incisor was previously restored with a compromising cantilever bridge. Interdisciplinary approach including orthodontics, orthognathic surgery, and prosthetic dentistry was performed and gave patient a better esthetic and functional result. Ways to achieve better esthetics, evaluation and possibility of surgery-first orthognathic approach, and other possible treatment options were discussed.
Treatment Of Facial Asymmetry By Mini-Implants Combined With One-Jaw Surgery, Ya-Ting Wang, Kang-Yee Wang, Hau-Hueng Chang, Chung-Chen Jane Yao
Treatment Of Facial Asymmetry By Mini-Implants Combined With One-Jaw Surgery, Ya-Ting Wang, Kang-Yee Wang, Hau-Hueng Chang, Chung-Chen Jane Yao

Facial asymmetry may originate from mandibular deviation combined with secondary maxillary compensation in vertical dimension, which can lead to occlusal plan canting. Two-jaw surgery would be an ideal choice for these cases in the past. Nowadays, using mini-implants to intrude elongated maxillary teeth to correct the occlusal plane canting could simplify the surgical plan into one-jaw surgery. In this case, a 30 y/o female was diagnosed with skeletal Class I malocclusion with mandibular deviation to left side combined with occlusal plane canting. The canted occlusal plane was corrected by intrusion of upper right posterior teeth with miniplate and minisrew first, …

Taiwanese Journal of Orthodontics
A case of mandibular prognathism with facial asymmetry was presented. Surgery-first orthognathic approach was performed that no pre-surgical orthodontic treatment was done before surgery. Within this treatment modality, patient had major profile improvement in the beginning of the treatment and total treatment time was shortened. The etiology of mandibular deviation, treatment principles of facial asymmetry, and the advantages of surgery-first orthognathic approach were discussed.

Correction Of Unexpected Post-Surgical Anterior Open Bite With Miniscrew Orthodontics – Case Report, Sam Sheng-Pin Hsu, Yu-Fang Liao, Hsin-Yi Hsieh, Grace Ya-Ying Teng, Yi-Ting Chiang, Shih-Han Chen
Taiwanese Journal of Orthodontics
A case of anterior open bite with facial asymmetry is presented. The un-expected anterior open bite and retrusive mandible occurred shortly following orthognathic surgery (LeFort I - 3 pieces + Bilateral sagittal split osteotomy + genioplasty). The anterior open bite was then successfully corrected with miniscrew orthodontics.Possible causes of post-surgical anterior open bite and the treatment options were discussed comprehensively.
