Background: The correction of Class II malocclusions is one of the most common treatments performed in the United States. Despite Class II malocclusions being one the most commonly presented problems for orthodontists, there is no consensus of which non-surgical treatment modality best impacts a patient’s quality of life long term. Purpose: This study examines the different non-surgical treatment approaches for patients with severe Class II division 1 and the impact of treatment outcomes on patient satisfaction and quality of life long term. Study Design: This study retrospectively analyzed the different treatment approaches and outcomes of class II division 1 with severe overjet, while prospectively assessing patient satisfaction and quality of life long term. Initial and final cephalometric and clinical variables for 83 patients (38 at Harvard School of Dental Medicine, 30 at the University of Iowa, and 15 in private practice in Iowa) treated non-surgically were recorded and analyzed. A retention clinical exam, at least 6 months post-debond, was done for final measurements, assessment of practitioner and patient satisfaction, and patient quality of life questionnaires. Results: Non-surgical treatment of severe Class II division 1 malocclusions yielded 5.54 mm overjet reduction and 0.51 mm of relapse in retention on average. Patients with more overjet at their long term retention check demonstrated significantly poorer satisfaction scores with the appearance of their bite (p<0.001), the appearance of their face (p<0.001), and with their overall orthodontic treatment (p<0.001). Extraction treatment was associated with significantly lower patient satisfaction scores of overall orthodontic treatment (p=0.023) and appearance of bite (p=0.018) but not facial appearance. Patients treated with extractions also showed higher QOL scores on the OHIP-14 (p=0.022) and CPQ (p=0.002) surveys, indicating that extraction therapy of severe Class II division 1 patients led to a significantly poorer quality of life. Conclusion: Non-surgical treatment of severe Class II division 1 malocclusions can yield excellent results and stability long term. Overjet can be dramatically reduced with non-surgical treatment but there is a tendency for overjet to relapse in retention. While treatment outcomes yielded high results of patient satisfaction, patients with more overjet in retention displayed significantly less satisfaction of the appearance of their bite, appearance of their face, and with their overall orthodontic treatment. Extraction treatment was associated with significantly lower patient satisfaction scores of overall orthodontic treatment and appearance of bite but not facial appearance. Patients treated with extractions showed poorer quality of life scores in retention compared to those treated nonextraction.

Former studies indicate that social media is a good way to communicate with stakeholders which also makes it an interesting and relevant focus for this study. As football is becoming more and more commercialized, the demands that non sports related activities are professionalized are raised ever higher. Between the professionals and Sunday league football teams, we find Division 1. A Swedish football league in limbo between the professionals and the amateurs. A league where the clubs manage to survive on pocket money and seldom with the possibility to hire staff on full time. The clubs in Division 1 have been the subject of this research to map how they communicate on the image sharing app, Instagram.  The purpose of this essay is to, through the issue “What patterns can be found on Instagram among the football clubs in the Swedish third tier leagues?” shine the light on the small sports clubs, and their day to day activity and communication. In the long run it will contribute to more effective communication for small organizations.  The thematic analysis of the empirical material shows that the clubs in Division 1 often use Instagram by routine or for the sake of it, rather than with a cut out strategy or plan. Even though it’s evident that a social media presence has positive effects in itself when it comes to building an identity as a club, with supporters and other parties, there are several measures football teams can take to improve their communication on Instagram. Having a  clear cut plan and goals can achieve things such as getting more active and loyal supporters with raised ticket sales as a long term result.

Um grupo foi tratado com aparelho Bionator, obtendo-se a correção da relação molar e da sobressaliência em 1,3 anos, em média, com idade inicial de 9,17 anos. O outro grupo, utilizado como controle, não recebeu tratamento, foi observado por 1,5 anos em média, com idade inicial de 8,68 anos. Para cada indivíduo havia uma telerradiografia obtida no início e outra no fim da observação. As variáveis cefalométricas foram mensuradas e submetidas ao tratamento estatístico. Os resultados demonstrarama que a correção da má oclusão classe II divisão 1 deveu-se principalmente as alterações dentárias promovidas pel Bionator, representando 71,31% da correção molar e 79,64% da correção da sobressaliência. Houve uma significativa diminuição do ANB pelo Bionator, mas a desejável ação de projeção mandibular não foi estatisticamente significante. Apesar de ter havido significativo aumento do comprimento mandibular, este foi contraposto pela rotação para posterior da mandíbula. Houve também restrição do crescimento maxilar horizontal, e estabilidade ântero-posterior da cavidade glenóide. Parece não haver indicação para o uso sistemático do aparelho Bionator, devendo sua utilização ser restrita a casos de maior retrusão mandibular, planejando-se a reversão dos efeitos de rotação mandibular, para se utilizar o crescimento extra condilar no aumento da protusão da mandíbula. / The effect of Bionator appliance in treatment of the malocclusion Class II division 1 was evaluated, with special emphasis to alterations in mandible.

The results demonstrated that the correction of the class II division 1 malocclusion was due, mainly, to dental alterations promoted by Bionator, representing 71.31% of the molar correction 79,64% of the overjet correction. There was a significant decrease of ANB angle with Bionator, but the desirable action of increase in mandibular protusion was no stastistically significant. In spite of having significant increase of the mandible length, this was opposed by the back rotation of the jaw. There was restriction of the horizontal maxillary growth, and antero-posterior stability of the glenoid fossa. It seems there is no indication for the systematic use of the Bionator, having its use to be restricted to cases of larger mandibular retrusion, being planned the reversion of the mandibular rotation, to use the extra condilar growth to the increase of the mandibular protusion.

Introduction: Class II Division 1 malocclusions are characterized by a retrusive mandible and prominent upper incisors. Despite Class II malocclusions being one of the most frequently treated cases in orthodontists' office, there is no uniform consensus in the orthodontic community on the best treatment modality and biomechanical approach to use in treating patients with Class II malocclusions. Purpose: This paper examines the end-of-treatment outcomes of severe Class II Division I malocclusion patients treated with surgical versus non-surgical approaches. Study Design: This is a retrospective study of consecutively treated severe Class II Division I patients at the University of Iowa. Initial and deband lateral cephalometric radiographs were compared between 45 non-surgical and 21 surgical patients. All patients that were debanded between the ages of 13 to 19 years were included. Multivariable regression analyses were used to examine differences in outcomes between treatment groups. Results: Following adjustment for patient level confounders (age, gender, and race), those treated surgically had better end of treatment cephalometric outcomes. Those treated surgically had a more balanced skeletal profile, greater reduction in overjet, and improvement in ANB angle (p Conclusion: Orthodontic treatment in conjunction with orthognathic surgery is a more ideal treatment for patients with severe Class II Division I malocclusion. When treated surgically, a greater amount of overjet can be reduced while keeping lower incisors in a more stable position in bone.

Magister Chirurgiae Dentium - MChD / The stable position of the mandibular incisors, and the extent to which their spatial position may be changed in the sagittal plane, represents a key point in determining orthodontic treatment goals and objectives. According to the equilibrium theory, the mandibular incisors lie in a narrow zone of stability that is governed by pressure from the lips, cheek, tongue and periodontium. Proclining the mandibular incisors more than 2 mm leads to instability because of an increase in lip pressure. The magnitude of incisor proclination therefore determines aesthetics, stability and function.

The purpose of this study was to determine if NCAA Division I-A football program success had a relationship to student-athlete graduation rates. Graduation rate data for 2001 were obtained from the NCAA and cumulative five-year records of selected NCAA Division I-A football programs determined winning percentage for the years 1996-2000. The data were examined by correlating the two variables of winning percentage and graduation rate. The findings show no significant correlation at a probability level of .05. The results of this study indicate the success of a football programs do not have any relationship to low football team graduation rates. Therefore, other factors such as athletic department ideals, commercialization of sport, or the preconceived notion that collegiate football athletes are only enrolled to compete in football may play a factor in graduation rates among NCAA Division I-A football players.

Background: The importance of nutrition on athletic performance is evident. Athletic trainers (ATs), nutritionists/RDs, strength and conditioning specialists (SCSs), and other athletic department personnel may be available to student-athletes and can be solicited for nutrition advice. Multiple studies have found that although some universities have a sports nutritionist on staff, student-athletes approached an AT most often for nutrition advice rather than an SCS, nutritionist or other person. ATs have the necessary education to provide proper nutrition information to student-athletes; however, it is not the primary role of an AT. Objective: The purpose of this study was to examine the quantity, quality and variety of nutrition support offered to Division I student-athletes who participate in football. Additionally, the purpose was to gain the perspective of the AT with regard to their role in educating football players on basic nutrition principles. Design: Cross sectional. Setting: Participants completed a web-based questionnaire. Patients or Other Participants: 253 Division I institutions were identified; from those institutions 120 head ATs were randomly chosen to receive the questionnaire. Responses from 30 (25%) head ATs (Football Bowl Subdivision 53.6%; Football Championship Subdivision 46.4%) were analyzed. Results: A majority (69%, n=20) of the institutions provided access to a nutritionist/RD. When asked who they believed student-athletes would solicit nutritional advice from first, respondents ranked their answers as follows: AT (n=11, 36.7%), SCS (n=10, 33.3%), nutritionist/RD (n=7, 23.3%), and coach (n=2, 6.7%). However, in the Likert scale questions, participants felt between neutral and slight agreement regarding their own responsibility, or that overall, ATs should feel responsible to teach nutrition or promote proper eating habits. In another question, participants were asked who is responsible for educating football players about nutrition at their institution and were able to select more than one response. Participants felt that all three professionals had a fairly high level of responsibility (SCS n=26, 86.7%; AT n=23, 76.7%; nutritionist/RD n=21, 70%). ATs ranked their perception of who helped with management of specific medical issues as follows: AT (n=26, 86.7%), nutritionist/RD (n=21, 70%), physician (n=18, 60%), and SCS (n=3, 10%). FBS institutions seem to provide more nutrition services compared to FCS institutions; 73.7% of FBS institutions are providing access to a nutritionist/RD and whereas only 26.5% of FCS institution provide this service. Conclusions: ATs from our study strongly agreed that nutrition plays an important role in performance. As shown in previous studies, ATs and SCSs were found to be the primary sources of nutrition information for student-athletes in Division I settings. This study gathered the AT’s perspective and perceived roles regarding where student-athletes receive nutrition information from most often. The ATs in this study confirmed that they felt the ATs and SCSs were primarily approached for nutrition advice. Although these ATs responded that the SCSs, ATs, and nutritionist/RDs were all responsible to educate football players at their institutions, the ATs answers were conflicting when they said that they did not feel the ATs role should be responsible for educating football players on nutrition and performance. Because ATs did perceive themselves as qualified, it is suggested that they may feel another professional of the sports medicine team is more appropriate to fill this role. A sports medicine team consisting of ATs, SCSs, nutritionists/RDs and physicians should work together to promote the benefits of nutrition and provide optimal services within their professional scope of their practice. In the absence of one or more professional, effective knowledge and communication must be maintained to assure that the roles of nutrition services are still provided to football players.

Dual career (DC) means that an athlete combines sport and study/work. A balanced DC strongly depends on an athlete's ability to cope with stressors and is of paramount importance to succeed with both studies and sport (Stambulova et al., 2015; Wylleman &amp; Reints, 2010). The study aimed to explore dual career (DC) motivation, stressors, and coping in Swedish football players. The participants were nine male student-football players from seven football clubs in Sweden aged between 22 to 27 (M = 24.84, SD = 1.50) in Division 1, Superettan, and Allsvenskan (three highest levels of football in Sweden). A semi-structured interview guide was designed to explore the study’s aim.      Based on the result, a thematic map was developed from the central concept, categories, themes, and sub-themes created from analyzing the corresponding data. The thematic map connects all parts of the results and summarizes the study. The results revealed that internal DC motivation dominated, but education was partly affected by external motivation. Lack of support, dealing with time pressure and the challenge with performance and pressure in DC were the most significant stressors. Student-athletes demonstrated different ways of coping with stressors. Three coping strategies were identified. The participants highlighted physical and mental recovery in DC and the importance of social support. Findings showed that Covid-19 (C-19) positively impacted education, where remote learning was beneficial. The discussion, therefore, highlights the recommendations for flexible academic programs for all student-athletes at university to facilitate DC. The study concluded that internal motivation, combined with social support and previous experiences, is the predominant factor in succeeding with DC. / Dubbel karriär (DC) betyder att en idrottare kombinerar sport och studier/arbete. En balanserad DC beror starkt på idrottarens förmåga att hantera stressfaktorer och är en avgörande faktor för att lyckas med både studier och sport (Stambulova et al., 2015; Wylleman &amp; Reints, 2010). Syftet med studien var att utforska svenska studerande fotbollsspelares erfarenheter med fokus på motivation, stressorer och stresshantering. Deltagarna bestod av nio manliga studerande fotbollsspelare, från sju olika fotbollsklubbar i Sverige vars ålder varierade mellan 22 till 27 (M = 24,84, SD = 1,50) i Division 1, Superettan och Allsvenskan (tre högsta fotbollsligorna i Sverige). En semistrukturerad intervjuguide designades för att studera syftet. Baserat på resultatet utvecklades en tematisk karta utifrån de kategorier, teman och sub-teman som uppkom av den analyserade datan. Den tematiska kartan är studies produkt som sammanfattar resultatet och hur de sammankopplade. Resultatet påvisar att dubbla karriärer drivs mer från inre motivation, men utbildning påverkas delvis av yttre motivation. Brist på stöd, hantering av tidspress och utmaningarna med prestation och krav inom DC var de största stressorer. Student-idrottare demonstrerade olika sätt att hantera stressfaktorer och tre hanteringsstrategier identifierades. Deltagarna lyfte fram fysisk och mental återhämtning i DC och vikten av socialt stöd. Resultaten visade att Covid-19 (C-19) påverkade utbildningen positivt, där distansundervisning var fördelaktig. Diskussionen vill därför lyfta fram rekommendationerna för flexibla akademiska program för alla studentidrottare vid universitetet för att underlätta DC. Studien drog slutsatsen att intern motivation, kombinerat med socialt stöd och tidigare erfarenheter, är de dominerande faktorerna för att lyckas med DC.

This study aimed to examine end-of-treatment outcomes of severe Class II Division I malocclusion patients treated with surgical or non-surgical approaches. This study tests the hypotheses that occlusal outcomes (ABO-OGS) at end of treatment will be similar while cephalometric outcomes will differ between these groups. A total of 60 patients were included: 20 of which underwent surgical correction and 40 of which did not. The end of treatment ABO-OGS and cephalometric outcomes were compared by Mann-Whitney U tests and multivariable linear regression models. Following adjustment for multiple confounders (age, gender, complexity of case, and skeletal patterns), the final deband score (ABO-OGS) was similar for both groups (23.8 for surgical group versus 22.5 for non-surgical group). Those treated surgically had a significantly larger reduction in ANB angle, 3.4 degrees reduction versus 1.5 degrees reduction in the non-surgical group (p=0.002). The surgical group also showed increased maxillary incisor proclination (p=0.001) compared to candidates treated non-surgically. This might be attributed to retroclination of incisors during treatment selection in the non-surgical group – namely, extraction of premolars to mask the discrepancy. Studies such as this are necessary because they begin to give practitioners view of not only the outcomes of a single treatment plan, but a comprehensive approach by providing evidence of the over-arching treatment used for successful treatment in both groups.
