Patient perceptions and attitudes regarding post-orthodontic treatment changes. Angle Orthod. (IF 3.4) Pub Date : 2023-07-01 Nurver Karslı,Irmak Ocak,Burak Gülnar,Tamer Tüzüner,Simon J Littlewood
OBJECTIVES To determine patient perceptions and attitudes regarding posttreatment changes at least 2 years after completion of orthodontic treatment. MATERIALS AND METHODS A total of 125 patients (75 females, 50 males, aged 22.93 ± 2.98 years) were enrolled at least 2 years after debonding. Participants had either vacuum-formed retainers (VFRs) or bonded retainers (BRs). Posttreatment changes were

Multidisciplinary approach to restore esthetics and function in a young patient with three consecutive impacted teeth: a case report with 18-month follow-up Angle Orthod. (IF 3.4) Pub Date : 2023-03-20 Luciana Quintanilha Pires Fernandes, Mariana Caires Sobral de Aguiar, Vera Lúcia Cosendey, Jonas Capelli Junior
This case report describes the orthodontic treatment of an 11-year-old patient with three maxillary impacted teeth on the right side. Cone-beam computed tomography showed that these teeth were close together, with the lateral incisor in a lower position, followed by the central incisor, and the canine in a more apical position. Treatment included applying traction to these teeth. A transpalatal arch

A cone-beam computed tomography study of hyoid bone position and airway volume in subjects with obstructive and nonobstructive adenotonsillar hypertrophy. Angle Orthod. (IF 3.4) Pub Date : 2023-07-01 Amin S Mohamed,Janvier Habumugisha,Bo Cheng,Minyue Zhao,Wenqing Bu,Lifeng Liu,Yucheng Guo,Rui Zou,Fei Wang
OBJECTIVES To investigate hyoid bone position and airway volume in subjects with adenoid hypertrophy, tonsillar hypertrophy, and adenotonsillar hypertrophy compared to subjects with nonobstructive adenoids or tonsils and to assess the correlation between hyoid bone and airway parameters. MATERIALS AND METHODS A total of 121 subjects were grouped based on adenoid or tonsillar hypertrophy into four groups

Evaluation of systemic Omega-3 PUFAs effect on orthodontic tooth movement in a rabbit model: RCT. Angle Orthod. (IF 3.4) Pub Date : 2023-07-01 Asser M Gad,Samia O Soliman
OBJECTIVES To evaluate the effect of systemic administration of omega-3 fatty acids on orthodontic tooth movement (OTM) with histological analysis. MATERIALS AND METHODS OTM was induced in 20 adult albino New Zealand rabbits, divided into omega-3 and control groups, with nickel-titanium coil springs for 21 days. Omega-3 or saline was given every day via oral gavage during the experimental period. Animals

The accuracy of artificial intelligence-based virtual assistants in responding to routinely asked questions about orthodontics. Angle Orthod. (IF 3.4) Pub Date : 2023-07-01 Anthony Perez-Pino,Sumit Yadav,Madhur Upadhyay,Lauren Cardarelli,Aditya Tadinada
OBJECTIVES To evaluate the utility and efficiency of four voice-activated, artificial intelligence-based virtual assistants (Alexa, Google Assistant, Siri, and Cortana) in addressing commonly asked patient questions in orthodontic offices. MATERIALS AND METHODS Two orthodontists, an orthodontic resident, an oral and maxillofacial radiologist, and a dental student used a standardized list of 12 questions

Skeletal and dentoalveolar effects of miniscrew-assisted rapid palatal expansion based on the length of the miniscrew: a randomized clinical trial. Angle Orthod. (IF 3.4) Pub Date : 2023-07-01 Eun-Hack Andrew Choi,Kee-Joon Lee,Sung-Hwan Choi,Hwi-Dong Jung,Hyung-Joon Ahn,Toru Deguchi,Jung-Yul Cha
OBJECTIVES To compare skeletal and dentoalveolar changes of miniscrew-assisted rapid palatal expansion (MARPE) according to the length of the miniscrews. MATERIALS AND METHODS This two-arm parallel-randomized controlled trial included 32 adult patients aged 19-35 years who received orthodontic treatment with MARPE. Patients were allocated to two groups, group long (L) and short (S), through block randomization

Effects of orthodontic camouflage treatment vs orthodontic-orthognathic surgical treatment on condylar stability in Class II hyperdivergent patients with severe temporomandibular joint osteoarthrosis: a retrospective observational study. Angle Orthod. (IF 3.4) Pub Date : 2023-07-01 Yajing Tian,Bochun Mao,Shengjie Cui,Yanning Guo,Ningrui Zhao,Yidan Zhang,Yanheng Zhou,Xuedong Wang
OBJECTIVES To investigate the differences in profile changes and stability of the condyles between orthodontic camouflage treatment assisted by vertical control and that accomplished via orthognathic surgery in Class II hyperdivergent patients with TMJ osteoarthrosis (TMJOA). MATERIALS AND METHODS This study included 27 Class II hyperdivergent TMJOA patients (54 condyles) who received orthodontic camouflage
