Early dentofacial orthopedic treatment of a patient with maxillary hypoplasia and congenital central hypoventilation syndrome
Publication date: March 2014 Source:Orthodontic Waves, Volume 73, Issue 1 Author(s): Mika Shibata , Chihiro Tanikawa , Kohtaro Yashiro , Yuko Shintaku , Mikihiko Kogo , Takashi Yamashiro Congenital central hypoventilation syndrome (CCHS) is a respiratory disorder characterized by compromised central and peripheral chemoreflexes that lead to hypoventilation during sleep. All patients with CCHS require lifelong ventilatory support during sleep; however, nasal bilevel positive airway pressure (BiPAP) therapy can cause maxillary hypoplasia. In the present case, the patient had been diagnosed with CCHS and was initiat...

Evaluation of effects of activator treatment on mandibular growth by analyzing components of condylar growth and mandibular rotation
Conclusion Both the sagittal condylar growth and counterclockwise mandibular total rotation attributed to activator treatment contribute to forward displacement of the mandible. The activator effects are expected greater in patients with flat mandibular plane, small gonial angle, backwardly inclined mandibular ramus and long posterior facial height.

Pattern of stress distribution in different bracket–adhesive–tooth systems due to debonding load application
Conclusion Despite the overall similarity in stress distribution pattern of different bracket–adhesive–tooth systems, some differences on pattern of stress distribution and magnitude of stress were also observed. This may bring about more susceptibility of curved enamel surface teeth to lower bond strength, damage and fracture than flat enamel surface teeth. (Source: Orthodontic Waves)

Questionnaire survey on pain and discomfort after insertion of orthodontic buccal miniscrews, palatal miniscrews and, orthodontic miniplates
Conclusion These results suggest that appropriate skeletal anchorage devices should be selected on a case-by-case basis, considering not only the mechanical effect but also the patients’ pain and discomfort levels. (Source: Orthodontic Waves)

Fallibility of Pont's index in a Bangladeshi population
Conclusion Significant correlations were noted for inter-premolar and inter-molar width. The findings suggest that Pont's index potentially overestimate the arch expansion required to alleviate crowding. (Source: Orthodontic Waves)

Stability of miniscrews with different continuous orthodontic forces as measured by cone-beam computed tomography
Conclusion This study concluded that miniscrews could be significantly displaced with 50 and 150g during 3 months wherein the heavier loading force essentially caused more miniscrew mobility. Clinically, it is suggested to use proper magnitude of force to miniscrews with care in order to overcome orthodontic anchorage failure. (Source: Orthodontic Waves)

The effects of palatoplasty and pre-surgical infant orthopedic treatment on occlusion in unilateral cleft lip and palate patients
Conclusion Dental arch relationship in UCLP patients was not influenced by the type of palatoplasty and the use of pre-surgical infant orthopedic treatment. Our results suggest that pre-surgical infant orthopedic treatment results in the increase of anterior dental width, whereas two-stage palatoplasty is significantly effective for increasing posterior dental width in UCLP patients.

Two-phase treatment in a patient with a skeletal Class III malocclusion: Early orthopedic treatment and subsequent camouflage treatment with temporary anchorage devices
Publication date: September 2014 Source:Orthodontic Waves, Volume 73, Issue 3 Author(s): Kae Hirata , Seiji Haraguchi , Wakako Tome , Takashi Yamashiro In this case report, we describe the outcome of a two-phase orthodontic approach used to treat a 4-year and 8-month-old girl who exhibited excessive negative overjet and skeletal Class III jaw relationship. In Phase I treatment, growth modification using a protraction headgear appliance was used to normalize maxillomandibular growth. A forward growth of the maxilla and a normal overjet were achieved. During pubertal growth period, a skeletal Class III jaw relationsh...

Bimaxillary protrusion trait in the Indian population: A cephalometric study of the morphological features and treatment considerations
Conclusion Unlike in other ethnic and racial groups, bimaxillary protrusion in Indian subjects is likely a bidental protrusion over normal dento-alveolar bases. The skeletal characteristics suggested a normal relationship of the functional components of the face. The condition could be treated successfully with orthodontic mechanotherapy alone.

Evaluation of facial asymmetry measurements on simulation model
Conclusion The correlation of the ratio and the center of mass based parameters can be differently influenced by type of deformations and facial anatomical zones. Center of mass based parameters may be used in conjunction with ratio parameters in order to differentiate type of asymmetry. (Source: Orthodontic Waves)

Comparison of perception of necessity of orthodontic treatment between orthodontists and dentists at dental check-ups with DAI
Conclusion There were two types of gaps in the perception of the necessity of orthodontic treatment. The first one is an individual difference among the dentists, which is related to the evaluation of missing teeth and space in the dental arches. The other is recognized as gaps in the perception between orthodontists and dentists, which are related to the amounts of crowding. It is important to realize the difference of perception and improve the mutual understanding to prevent overlooking malocclusion. (Source: Orthodontic Waves)
