RESUMO

Bimaxillary protrusion is a clinical condition with high prevalence rate, which damages facial esthetics and affects the mental health of patients. Its clinical manifestations include protrusion of lips, overexposure of teeth, vertical and sagittal overdevelopment of alveolar bone in the anterior areas of upper and lower anterior jaws, and so on. The common protocols for the treatment of severe bimaxillary protrusion is orthodontic treatment with exaction of premolars or combined orthognathic-orthodontic treatment. However, either method is of great difficulty. By systematic mechanical design, the author used the treatment system of customized lingual appliances associated with corticotomy to realize the vertical and torque control of the anterior teeth, and obtain the orthodontic treatment effect of both esthetics and health. The clinical strategies for the treatment of severe bimaxillary protrusion were provided.

RESUMO

In last decades, the number of adult patients requesting orthodontic treatments has increased. Orthognathic surgery allows correction of skeletal dysmorphoses in adults. The management of osteoporotic patients treated with bisphosphonates is a major challenge for orthodontists and maxillofacial surgeons. Few studies have been conducted in these patients and four cases of orthognathic surgery have been described to date. A rare case of orthodontic surgical treatment in an osteoporotic patient who has been treated with bisphosphonates is reported. A 38-year-old patient wishing to improve the aesthetics of her face presented in dentofacial orthopedic consultation. Anamnesis revealed a history of bisphosphonate treatment for osteoporosis. The patient presented a hyperdivergent skeletal class III with laterognathia. The occlusal diagnosis was a class III with premolar and canine open bite, interincisal media discordance and dental crowding. The patient was treated by orthodontics and maxillomandibular osteotomy. A postoperative bone Healing delay of four weeks was recorded. This case report discusses the possibility of performing orthodontic treatment associated with orthognathic surgery in patients treated with bisphosphonates in context of osteoporosis. Orthodontics and maxillofacial surgeons must be prepared for the management of patients treated with bisphosphonates. Studies should be considered in order to specify the optimal methods of management.

RESUMO

(1) Objective: To investigate the oral health-related quality of life (OHRQoL) and self-esteem (SE) of a population with cleft lip and/or palate (CLP) and to compare it with a non-affected control cohort. (2) Materials and methods: This study comprised 91 CLP patients and a control group of 790 individuals, seeking orthodontic treatment. OHRQoL and SE were assessed by the Child's Perception Questionnaire (CPQ) and the Dutch adaptation of the Harter's Self-Perception Profile for Adolescents. Treatment need and self-perception of oral aesthetic were assessed using the Index of Orthodontic Treatment Need (IOTN) and the Oral Aesthetic Subjective Impact Scale (OASIS). Patients' expectations and motivation for treatment were also scored. Linear models were used for statistical comparisons between groups. (3) Results: The cleft group scored higher in all domains of the CPQ, OASIS, IOTN and regarding SE for the domains of scholastic competence, athletic competence, physical appearance and behavioral conduct. The cleft group was not only more motivated and expected less discomfort during treatment but also had higher expectations for the treatment outcome. (4) Conclusions: The OHRQoL of CLP patients is strongly correlated with the presence of an oral cleft, while SE remains a personal resource not influenced by the malocclusion or medical condition.

RESUMO

The retention phase has become an accepted part of orthodontic therapy. Irrespective of the patient's age, underlying malocclusion or the type of mechanotherapy, an orthodontist will use some retention method in virtually every patient following completion of the active treatment. This article presents a short description of the history of orthodontic retention and highlights major developments in retention strategy.

RESUMO

PURPOSE:This study was aimed to investigate the effect of malocclusion on self-esteem of children aging 8 to 10 years in Chongqing. METHODS:According to the standards of the Fourth National Oral Health Epidemiological sampling survey,a multistage, stratified, cluster, and random sampling method was used to select 1 588 children from 12 schools in 3 districts and 3 counties in Chongqing. The part of tooth health of the Index of Orthodontic Treatment Need (IOTN) was used to evaluate malocclusion. The aesthetic part of the IOTN was used to evaluate the subjective orthodontic treatment need. The Harter's Self-perception Profile for Children was used to evaluate the self-esteem. The data were analyzed with SPSS 20.0 software package. RESULTS: Subjective orthodontic treatment need IOTN-AC(moderate severe), overjet (severe: 6-9 mm, >9 mm), anterior crossbite, open bite, caries located in the anterior tooth area were negatively correlated with self-esteem(P<0.05). CONCLUSIONS: Subjective orthodontic treatment need and malocclusion, especially the types that have great influence on beauty obviously affect children's self-esteem. It is necessary to increase the investment and education of early orthodontic intervention.

RESUMO

Alveolar distraction osteogenesis (ADO) has been used for the reconstruction of atrophic alveolus for decades. The advantage of this technique is that it augments the bone and soft tissues together, creating a better alveolar platform for subsequent surgeries and dental rehabilitation. It is especially useful in patients with large and/or complex alveolar clefts for which approximating the alveolar segments reduces the size of the bony cleft and associated fistula. Displacement of the transported segment is the most frequently encountered complication of ADO but can be managed by constructing case-specific distractors.

RESUMO

INTRODUCTION: Determination of improvement in orthodontic treatment may depend on the measurement method used and the purpose. METHODS: Improvement after orthodontic treatment (from T1 to T2 [beginning to end of treatment]) was assessed 3 ways from a set of 98 patient records: (1) calculated by subtracting judges' assessments at T2 from T1 for records presented in random order, (2) judged as a holistic impression viewing T1 and T2 records side by side, and (3) determined from proxies (American Board of Orthodontics Discrepancy Index, the American Board of Orthodontics Objective Grading System, and the Peer Assessment Rating index). RESULTS: High levels of intramethod consistency were observed, with intraclass correlation coefficient clustering around an intraclass correlation coefficient of 0.900, and distributions were normal. Calculated and judged improvements correlated at r = 0.606. Calculated or judged improvements were correlated at a lower level with proxies. Calculated improvement was significantly associated with "challenge" (T1) scores and judged improvement associated with "results" (T2) scores. Common method bias was observed, with higher correlations among similar indexes than among indexes at the same time that used various methods. Relative to differences in Peer Assessment Rating scores, calculated improvement overestimated low scores and underestimated high ones. The same effect, but statistically greater, was observed using direct judgment of improvement. CONCLUSIONS: These findings are consistent with decision science and measurement theory. In some circumstances, such as third-party reimbursement and research, operationally defined measures of occlusion are appropriate. In practice, the determination of occlusion and improvement are best performed by judgment that naturally corrects for biases in proxies and incorporates background information.

RESUMO

INTRODUCTION: This study aimed to compare patients' Salzmann Index scores for those who applied for Medicaid orthodontic coverage in Pennsylvania with their corresponding American Board of Orthodontics discrepancy index (DI) scores to assess if there is a correlation between Salzmann and DI scores. In addition, a threshold DI score was calculated that would correspond to Medicaid coverage approval. The study intended to answer the following questions: is there a correlation of 0.7 or greater between a patient's Salzmann Index and their DI? If so, is there a particular DI score that can be used as the minimum score for approving Medicaid orthodontic coverage in the state of Pennsylvania? METHODS: Salzmann Index scores, DI scores, and approval and disapproval results for Medicaid orthodontic coverage were obtained from 104 subjects aged between 10 and 17 years. A linear regression model was generated to assess if there was a correlation between the Salzmann scores and DI scores. If a correlation coefficient of 0.7 or greater were found, a threshold Salzmann Index score would be determined for subjects who were approved for Medicaid orthodontic coverage. The threshold Salzmann score would be used in the linear regression formula to find the corresponding DI score, which would be designated as the threshold DI score for approval for Medicaid orthodontic coverage in the state of Pennsylvania. RESULTS: A Pearson correlation of 0.453 was calculated between the 104 Salzmann scores and DI scores, demonstrating a moderate correlation. With the correlation coefficient being lower than 0.7, binary logistic regressions were calculated to assess the predictability between a given Salzmann score and approval and disapproval for Medicaid orthodontic coverage. The Salzmann score had an overall 68.3% success in predicting Medicaid orthodontic coverage approval/disapproval. Of the 58 subjects that were approved for Medicaid orthodontic coverage, 46.6% had Salzmann scores equal to or greater than 25. Of the 46 subjects that were disapproved for Medicaid orthodontic coverage, 78.3% had Salzmann scores equal to or less than 24. CONCLUSIONS: With the lack of high prediction rates seen from the results of the regression models, the current system of Medicaid does not appear to show consistency for assessing the need for orthodontic treatment coverage. Multiple insurance companies that participate under Medicaid require a Salzmann score of 25 or greater for approval; however, the results show the Salzmann score is arbitrary in terms of approval and disapproval. There appear to be underlying factors apart from the Salzmann score that the Pennsylvania Medicaid system uses to justify whether a patient was approved or denied for coverage.

RESUMO

BACKGROUND: The aim of this study was to determine the retention practices following orthodontic treatment in a tertiary health institution in Nigeria. METHODS: A retrospective study conducted in the Orthodontic Clinic of the Lagos University Teaching Hospital over a 3-year-period. Data on the type of retainers used and the retention practices in the upper and lower arches were obtained from case files of patients who had completed orthodontic treatment in the institution. Statistical analysis was performed using IBM SPSS software version 23. RESULTS: The demographic variables comprised of 136 subjects; 93 females (68.4%) and 43 males (31.6%). Their ages ranged from 9-44 years with a mean age of 18.96 ± 6.75. Class I malocclusion was the most common malocclusion pattern (84.6%), followed by Class II (10.3%) and Class III (5.1%). Removable retainers were more commonly used and accounted for retention carried out in 85.3% of the study population. There was a preference for the use of removable retainers in the upper arch; the Hawley retainer being the most used (79.4%). In the lower arch however, no form of retention was carried out for majority of the patients after orthodontic treatment (86.8%). However, when done, the fixed lingual retainer was the most frequently used (13.2%). CONCLUSION: The Hawley retainer was the predominant retainer in this study. The fixed lingual retainer was the most frequently used in the lower arch. Longitudinal studies are required to determine efficacy of different types of retention following orthodontic treatment.

RESUMO

ABSTRACT: This retrospective study aimed to explore the effect of orthodontic treatment (ODT) on anterior tooth displacement (ATD) caused by periodontal disease (PD).A total of 72 patients were selected and were divided into a control group (n = 36) and an experimental group (n = 36). Patients in both groups received conventional periodontal treatment. In addition, patients in the experimental group also received ODT. Outcomes include probing depth, percentage of bleeding sites, clinical attachment loss, clinical crown length, tooth root length, and periodontal tissue of the affected tooth (alveolar bone height, periodontal pocket depth, bleeding index).After treatment, the patients in the experimental group achieved more improvements in probing depth (P < .01), percentage of bleeding sites (P < .01), clinical attachment loss (P < .01), clinical crown length (P = .04), and periodontal tissue of the affected tooth (periodontal pocket depth (P < .01), and bleeding index (P < .01)), than those of patients in the control group.This study suggests that ODT is beneficial for ATD caused by PD. Future studies are still needed to verify the findings of this study.

RESUMO

Introduction: patients´ satisfaction with their dental appearance and tooth colour is often influenced by certain factors which need to be addressed periodically among different populations. Methods: a self-administered questionnaire consisting of sociodemographic data, questions on patients´ satisfaction with tooth colour, perceived malalignment of teeth, non-aesthetic anterior tooth-coloured restoration and presence of tooth fracture were distributed. Data collected was analysed using Statistical Package for Social Sciences (IBM, SPSS version 20). Chi square was used to test the statistical differences at a significance of p> 0.05. Results: a total of 410 patients (M=147, F=263) participated in the study. About 73% had tertiary education while 36.3% were within the modified ISCO-08 Group 2. The respondents that were satisfied with the general dental appearance and tooth shade were 66.3% and 63.5% respectively. More males (65.1%) than females (62.7%) were satisfied with tooth colour while more females (69.1%) were satisfied with dental appearance. The older age group were more satisfied with dental appearance and tooth colour. Awareness of tooth whitening (Over 80%) and the desire to undergo tooth whitening was more among the post-secondary individuals. More of dental patients (73.1%) than medical (59.2%) were satisfied with teeth appearance (p=0.003). Conclusion: patients are increasingly aware of their dental appearance/tooth colour and the need to improve it with tooth bleaching and/or orthodontic treatment. Female were more dissatisfied with their tooth colour but more satisfied with their dental appearance than the male. Older people were more satisfied with their dental appearance and tooth colour compared to younger age group.

RESUMO

Digital technologies are gradually integrating our orthodontic practices and retainers, often less considered compared to active devices, are also benefiting. The author will give in this article a brief presentation of the various current possibilities offered by the use of digital tools for carrying out and monitoring fixed or removable retention methods. The digital workflow is perfectly suited to the production of modern and durable retainers, whether for fixed or removable devices, as well as their long-term monitoring. The objective is not to decide on the superiority of one system over another, but to expose all the possibilities for adapting the digital tool to the orthodontist's method of retention. The benefit of using digital technology is saving time and improving performance, minimizing unnecessary manipulation and improving device precision. Digital technology provides all the elements necessary to achieve new generation retainers both more simply, and for them to be more precise and more durable. These technologies are in constant progress and we can still consider improvements in the near future as software and hardware developments progress.

RESUMO

BACKGROUND: Maxillary protraction with or without expansion is a widely known orthopedic treatment modality in growing skeletal Class III patients. However, limited data are available regarding the outcomes of long-term changes in the maxilla. Aim of this meta-analysis was to assess the effectiveness of the long-term maxillary anteroposterior changes following a facemask therapy with or without rapid maxillary expansion in growing skeletal Class III patients. METHODS: A comprehensive literature search was conducted using the databases of PubMed, Science Direct, Web of Science, and Embase. Randomized controlled trials and cohort studies, published up to Sep. 2020, with maxillary protraction and/or expansion as keywords were included in this meta-analysis. Risk of bias within and across studies were assessed using the Cochrane tools (RoB2.0 and ROBINS-I) and GRADE approach. Overall and subgroup comparisons with the random-effect model were performed in this meta-analysis. Meta-regression models were designed to determine potential heterogeneity. RESULTS: There was a statistically significant increase (Mean difference, 2.29°; 95% confidence interval, 1.86-2.73; and p < 0.001 after facemask (FM) protraction. Mean difference, 1.73°; 95% confidence interval, 1.36-2.11; and p < 0.001 after rapid maxillary expansion(RME) and facemask protraction) in the Sella-Nasion-A point (SNA) angle in the treatment groups as compared with the control groups, when measured during the less than 3-year follow-up period. However, no statistically significant changes (Mean difference, 0.28°; 95% confidence interval, -0.57-1.13; and p = 0.52 after facemask protraction. Mean difference, 0.34°; 95% confidence interval, -0.64-1.33; and p = 0.50 after rapid maxillary expansion and facemask protraction) were observed in the SNA angle in the groups, when measured after 3 years of follow-up. Meta-regression analysis also showed that with increased follow-up duration, the effectiveness of maxillary protraction decreased. CONCLUSION: This meta-analysis revealed that maxillary protraction therapy could be effective for a short-term in correcting maxillary hypoplasia and the treatment result was not affected by mean age and sex. However, with increased follow-up duration, the sagittal maxillary changes gradually decreased. Limitations on this review were only the SNA angle was used and clinical heterogeneity was not discussed. The quality of evidence was moderate. Further long-term observational studies are necessary for a comprehensive evaluation of the effects on maxillary skeletal changes.

RESUMO

Background: To correlate the need for orthodontic treatment between the self-perception of Chilean adolescents from 14 to 18 years old with the observation of a dentist using the same assessment scale, as well as to determine if covariates such as gender, age and type of school influence the self-perception of the adolescent and the examiner. Material and Methods: Cross-sectional descriptive study of adolescents aged 14 to 18 years from public, subsidized and private schools in Temuco, Chile. The probability sample is stratified by course, from first to fourth year, a total of 414 students participated, according to the eligibility criteria. The photographic score of the aesthetic component (AC) of the Index of Orthodontic Treatment Need (IOTN) was used. The statistical analysis of the data was performed with the SPSS Statistics program v.23. Results: 94.9% of the adolescents perceived themselves as having good aesthetics. The examiner considered that 77% presented this condition, p<0.00. Males perceived themselves better than females. At age 15, 1.7% of students considered themselves to have poor aesthetics, p<0.01. From the examiner's perspective, aesthetics are related to type of school, p<0.00. Conclusion: Adolescents perceive themselves better aesthetically than do the evaluators. The school type factor, according to the IOTN-AC examiner, shows a higher proportion of students with no need for orthodontic treatment in private schools, and a threshold need in municipal and subsidized institutions.


Correlacionar la necesidad de tratamiento ortodóncico, entre la autopercepción de adolescentes con el diagnóstico de un evaluador odontólogo, utilizando la misma escala de valoración, así también determinar si las variables como el género, la edad y la dependencia educacional influyen en la autopercepción del adolescente y la observación del examinador. Material y Métodos: Estudio descriptivo de corte transversal, en adolescentes de 14 a 18 años de escuelas públicas, subvencionadas y privadas de Temuco-Chile. Muestreo probabilístico estratificado por cursos, de primero a cuarto medio con una muestra de 414 estudiantes, según los criterios de elegibilidad. Se utilizó el score fotográfico del componente estético (AC) del Índice de Necesidad de Tratamiento de Ortodoncia (INTO). El análisis estadístico de los datos fue realizado con el programa SPSS Statistics v.23. Resultados: El 94,9% de los adolescentes se autoperciben con una buena estética, el examinador considera que un 77% presenta esta condición, p<0,00. Los varones se perciben mejor que las damas. Los adolescentes de 15 años un 1,7% considera tener mala estética, p<0,01. Desde la perspectiva del examinador la estética se relaciona con la dependencia educacional, <0,01. Conclusión: Los adolescentes se autoperciben mejor estéticamente que lo diagnosticado por evaluadores odontólogos. El factor dependencia educacional según INTO-AC examinador, muestra mayor proporción de estudiantes sin necesidad de tratamiento ortodóncico en los establecimientos privados, y necesidad límite en los públicos y subvencionados.
