Literature Review: Corticotomy-Assisted Orthodontic Treatment, Lei Kang, Shou-Hsin Kuang, Tzu-Ying Wu
Taiwanese Journal of Orthodontics
Corticotomy-assisted orthodontics (CAOT) can shorten orthodontic treatment time by increasing regional acceleratory phenomenon. The periodontal wound healing caused by corticotomy are similar to the periodontal tissue reaction induced by orthodontic force; if the two phenomena could be accumulated and both enhancing bone remodeling, orthodontic tooth movement should be accelerated theoretically. There are many different kinds of procedures and strategies in the clinical application of corticotomy-assisted orthodontics, but when the cost and benefit ratio for the patients are thoroughly considered, using minimal invasive corticotomy to assist orthodontic treatment may be more practical. As for the clinical efficacy of minimal invasive corticotomy, …

Taiwanese Journal of Orthodontics
It has been more than seven decades that traditional two-dimensional (2D) image develops into threedimensional (3D) image. Due to the limited technology, 2D lateral cephalograms are traditionally used for airway assessment; however; the problem with cephalometry is that the 3D airway change can only be measured by linear measurement. Since 1990s, the development of cone beam computed tomography (CBCT) has offered more information for orthodontists, which is considered to be a diagnostic tool and initially served as the radiographic standard for airway assessment for patients with obstructive sleep apnea (OSA). Over the years, more studies on 3D reconstruction in airway …

The replacement of teeth by osseointegrated implants is usually restricted to patients with completed craniofacial growth. Implant insertions in children, adolescents and young adults who we refer to as young patients are circumvented due to several unfavorable potential effects including trauma to tooth germs, tooth eruption disorders, and multidimensional restrictions of dental alveolus and skeletal craniofacial growth. The clinical and radiographic findings have clearly shown that the implants do not behave like normal erupting teeth during the development of the dentition. Neither does the fixtures move together with the adjacent teeth, but behaves more like ankylosed teeth. This was a …

Objective: The aim of this study was to investigate the morphological characteristics of the craniofacial pattern in skeletal Class II adults with mandibular retrusion. Materials and methods: Lateral cephalograms of 80 adults with skeletal Class II malocclusion with mandibular retrusion (∠ANB > 5°, ∠FNB < 86°) compared with 80 adults with normal occlusion (equal sexes in both groups). Thirty five landmarks were identified and digitized. Cephalometric analysis utilizing 30 linear, 29 angular and 4 ratio measurements were undertaken. Statistical comparison of the two groups was performed with Student’s t-test and 2 way-ANOVA. Results: (1) The skeletal Class II sample with mandibular retrusion had longer anterior cranial base length but the internal cranial base angle and the saddle angle were not different from the normal occlusion subject. (2) The sample with mandibular retrusion had longer maxillary length but the maxilla was in normal position related to the cranial base. The mandible was more retrusive and smaller but the ramus width was wider than normal occlusion subject due to compensatory growth. (3) The mandibular retrusion sample had more tilting maxillary plane, mandibular plane, ramus plane and occlusal plane. The sample had longer total anterior facial height, longer upper and lower anterior facial height and shorter posterior facial height (shorter ramus height) than normal occlusion subjects. Hyperdivergent facial pattern and the mandible rotated clockwisely were noted. (4) The mandibular retrusion sample had extrusive but normal inclined upper incisors, more inclined and extrusive lower incisors, smaller interincisal angle, larger overjet and deep overbite. (5) The mandibular retrusion group had more mesial tipping and more extrusive upper 1st molars. Besides, more mesial tipping, more retrusive, and more extrusive lower 1st molars were noted. Conclusion: Multiple variations of skeletodental features were found for skeletal Class II malocclusion with mandibular retrusion.
