The case report describes the orthodontic management of 19-year-old non-identical twins diagnosed with bimaxillary dentoalveolar protrusion on a Class I skeletal base with severe crowding using two different treatment mechanics. The first patient was treated with frictionless mechanics by making use of Kalra simultaneous intrusion and retraction arch for space closure, whereas the friction mechanics accomplished the task in the second patient with mini-implant (Titanium mini-implant, FavAnchor™ SAS, Favorite supplies, Thane west, Maharashtra, India) assisted power arm (Power hook, Azdent Orthodontics, Zhengzhou, China) retraction. It evaluated the overall treatment duration, anterior torque control, and level of comfort for the patients with the two mechanics. The post-treatment results in both cases exhibited remarkable change in inclination of upper anterior teeth which were established through cephalometric findings. Moreover, the anterior torque control was comparatively superior with loop mechanics over mini-implant assisted sliding mechanics. Both the treatment mechanics effectively and efficiently corrected the malocclusion with considerable impact on soft-tissue profile.","PeriodicalId":42593,"journal":{"name":"APOS Trends in Orthodontics","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141103179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Satisfaction is a multidimensional concept, requiring multi-item questionnaires for it to be adequately assessed. A 58-item, orthodontic patient satisfaction questionnaire (PSQ) was developed to assess orthodontic patient satisfaction. Appropriately adapted assessment tools are needed to assess orthodontics patient satisfaction in different populations. The validity and reliability of such tools should be demonstrated before their use for each target population. The PSQ was yet to be validated in Arabic. Therefore, the objective of this study was to translate, adapt, and validate an Arabic orthodontic PSQ.\u0000\u0000\u0000\u0000The 58-item English PSQ was translated to Arabic through translation and back-translation. An expert panel examined the relevance of PSQ items. The questionnaire was circulated through social media to recruit responses from Arabic-speaking orthodontic patients who completed orthodontic treatment. Cronbach’s alpha, item-total correlation (I-TC), and kappa reliability coefficient were calculated. The analysis of variance test was used to compare satisfaction scores between genders and different orthodontic treatment appliances.\u0000\u0000\u0000\u0000Ten items were removed based on expert ratings.

Nine questionnaire items were removed because of low I-TC (<0.3). The resulting 39-item questionnaire had a Cronbach alpha of 0.79 and a kappa coefficient of 0.82. The mean total PSQ score of the sample was 167.61 ± 21.45. Items with the top ten highest I-TC correlations had a Cronbach’s alpha of 0.90. Patients on metal braces had a highest mean total PSQ score (P = 0.004).
