Considering the large number of fixed functional appliances, choosing the best device for your patient is not an easy task. To describe the development of fixed functional appliances as well as our 20-year experience working with them. Fixed functional appliances are grouped into flexible, rigid and hybrid. They are different appliances, whose action is described here. Four clinical cases will be reported with a view in illustrating the different appliances. Rigid fixed functional appliances provide better skeletal results than flexible and hybrid ones. Flexible and hybrid appliances have similar effects to those produced by class II elastics. They ultimately correct class II with dentoalveolar changes. From a biomechanical standpoint, fixed functional appliances are more recommended to treat class II in dolichofacial patients, in comparison to class II elastics. The electromyographic (EMG) activity of masticatory muscles was monitored longitudinally with chronically implanted EMG electrodes to determine whether functional appliances produce a change in postural EMG activity of the muscles. Pre-appliance and post-appliance EMG levels in four experiments that had been fitted with functional appliances were compared against the background of EMG levels in controls without appliances. The insertion of two types of functional appliance to induce mandibular protrusion was associated with a decrease in postural EMG activity of the superior and inferior heads of the lateral pterygoid, superficial masseter, and anterior digastric muscles; the decrease in the first three muscles was statistically significant. This decreased postural EMG activity persisted for approximately 6 weeks, with a gradual return towards pre-appliance levels during a subsequent 6-week period of observation. Progressive mandibular advancement of 1.5 to 2 mm every 10 to 15 days did not prevent the decrease in postural EMG activity. KEY WORDS Orthodontics, Class II Malocclusion, Fixed Functional Appliance.

Fixed functional appliances correct class II malocclusion by bringing the mandible forward into a new position. Patients using Fixed Functional Appliances complain of difficulty in oral hygiene, soft-tissue irritation, appliance breakage, and difficulty in mastication. Hence, the aim of this study was to conduct a survey evaluating patients’ acceptance of various fixed functional appliances in a university set up. This questionnaire-based study was a university-based setting which consisted of 10 closed-ended and open-ended questions out of which 2 were open-ended questions and 8 were close-ended. It covered discomfort, difficulty in speech, brushing, mastication, oral hygiene and fracture of the appliance. Descriptive statistics were performed. Chi-square test was used to determine the discomfort experienced due to the duration of wear. The significance level for the p-value was set at 0.05. Chi-square test reported that statistically, the insignificant association observed between duration of wear and level of discomfort (p>0.31). All functional appliances have their own disadvantages and discomfort, which is dependent on the intricate fabrication as well as their implementation. Within the limits of the study, it was observed that discomfort was more in the initial few days but reduced over a period of time as the patients got adapted to the appliance.

ABSTRACT Background Management of class II malocclusion in adolescent patients by growth modulation is one of the most debated topics in orthodontics. Noncompliance has been a major concern for orthodontists. Case report This case report describes the management of severe class II malocclusion in adolescent patient using functional appliance system—Forsus to correct class II problems, which is clipped on to bands. This appliance has several advantages, as the patient cannot remove it. It acts on the teeth and jaws for 24 hours each day, patient cooperation is not a problem, and as a result the treatment time is short. There is lot of controversy about the use of functional appliances. Conclusion This case report illustrates that even today, functional appliances have a significant role in the management of class II malocclusion by using growth modulation. The growth modulation minimizes the necessity of extraction of permanent teeth and probably orthognathic surgery. Clinical significance Functional appliances have a significant role in the management of class II malocclusion. The growth modulation minimizes the necessity of extraction of permanent teeth and probably orthognathic surgery. How to cite this article Vijayalakshmi PS, Veereshi AS.

ABSTRACT Treatment of class II malocclusion has always been an enigma to the orthodontic fraternity. Noncompliant correction of class II malocclusion using fixed functional appliances at the deceleration stage of growth has gained tremendous popularity in the recent times. Aim of the illustrated article is to demonstrate the efficacy of a fixed functional appliance in correction of class II malocclusion. We are reporting a 12-year-old female patient with a skeletal class II malocclusion treated using the Forsus appliance. Forsus FRD was the best option considering age, patient comfort, ease of installation, predictable results and patient compliance. The appliance was worn for 5 months after the initial alignment with fixed mechanotherapy (MBT 0.022"). The mandible was brought forward to a class I skeletal and dental relationship by the end of this phase of treatment.

ABSTRACT Objective: To compare patients’ perceptions of fixed and removable appliance therapy for correction of anterior crossbite in the mixed dentition, with special reference to perceived pain, discomfort, and impairment of jaw function. Material and Methods: Sixty-two patients with anterior crossbite and functional shift were recruited consecutively and randomized for treatment with fixed appliances (brackets and archwires) or removable appliances (acrylic plates and protruding springs). A questionnaire, previously found to be valid and reliable, was used for evaluation at the following time points: before appliance insertion, on the evening of the day of insertion, every day/evening for 7 days after insertion, and at the first and second scheduled appointments (after 4 and 8 weeks, respectively). Results: Pain and discomfort intensity were higher for the first 3 days for the fixed appliance. Pain and discomfort scores overall peaked on day 2. Adverse effects on school and leisure activities were reported more frequently in the removable than in the fixed appliance group. The fixed appliance group reported more difficulty eating different kinds of hard and soft food, while the removable appliance group experienced more speech difficulties. No significant intergroup difference was found for self-estimated disturbance of appearance between the appliances. Conclusions: The general levels of pain and discomfort were low to moderate in both groups. There were some statistically significant differences between the groups, but these were only minor and with minor clinical relevance. As both appliances were generally well accepted by the patients, either fixed or removable appliance therapy can be recommended.

Full textAbstract:
Treatment of complex malocclusion poses a challenge for the orthodontist because of its multifactorial aetiology. Class II malocclusion is the most frequently encountered and treated malocclusion in orthodontic practice and affects approximately 14.6 % of the North Indian population.1 A common reason for Class II malocclusion is mandibular skeletal retrusion which is the most common characteristic, as reported by McNamara.2 This can be caused by genetic or hereditary factors. When evaluating treatment options for Class II patients, the extent of the skeletal discrepancy and the skeletal maturity of the patient needs to be considered. Treatment may range from dental compensation including camouflage with extractions to surgical procedures targeted at moving the jaw at fault. In growing patients, growth modification with functional appliances offers an intermediate treatment option. Functional appliances are basically of two types; Removable and Fixed. Removable functional appliances such as Activator, Bionator, Frankel Function regulator and Twin Block appliance change Class II relationship by the transmission of soft tissue tension to the dentition. Treatment success with these appliances relies heavily on patient compliance. Therefore, in non-compliant patients, fixed Class II correctors in conjunction with fixed orthodontic appliances are the best choice.3 Fixed functional appliances generate continuous stimuli for mandibular growth without break and permit better adaptation to functions like mastication, swallowing, speech and respiration.1 The Herbst fixed functional appliance has been used routinely for Class II patients and has undergone many design variations over time.4 The AdvanSync2 Class II corrector is a recently introduced fixed functional appliance. It has a much smaller size than the conventional Herbst appliances, is easier to place, activate and remove and most importantly, can be used in conjunction with full-arch fixed appliances throughout.3 Here we describe a case report of a patient treated with the AdvanSync2 Class II corrector and the findings observed in the sagittal and vertical dimensions

Full textAbstract:
The introduction of mini-implants has broadened the range of tooth movements possible by fixed appliance therapy alone. The limits of fixed orthodontic treatment have become more a matter of facial appearance than anchorage. Many complex cases which would previously have required surgery or functional appliances can now be treated with fixed appliance therapy using mini-implants. A mutilated dentition case where mini-implants were used to provide anchorage for intrusion of molars and retraction of anterior teeth is reported here to illustrate this point.

ABSTRACT Objective: This study aimed at comparing the dentoskeletal changes in patients with Class II division 1 malocclusion, treated with three types of fixed functional appliances. Methods: A sample comprising 95 patients with the same malocclusion, retrospectively selected, and divided into four groups, was used: G1 consisted of 25 patients (mean age 12.77 ± 1.24 years) treated with Jasper Jumper appliance; G2, with 25 patients (mean age 12.58 ± 1.65 years) treated with the Herbst appliance; G3, with 23 patients (mean age 12.37 ± 1.72 years) treated with the Mandibular Protraction Appliance (MPA); and a Control Group (CG) comprised of 22 untreated subjects (mean age 12.66 ± 1.12 years). Intergroup comparison was performed with ANOVA, followed by Tukey test. Results: The Jasper Jumper and the Herbst group showed significantly greater maxillary anterior displacement restriction. The Jasper Jumper demonstrated significantly greater increase in the mandibular plane angle, as compared to the control group. The MPA group demonstrated significantly greater palatal inclination of the maxillary incisors. Vertical development of the maxillary molars was significantly greater in the Herbst group. Conclusions: Despite some intergroup differences in the amount of dentoskeletal changes, the appliances were effective in correcting the main features of Class II malocclusions.

Objective: To compare young people’s experiences of wearing a range of orthodontic appliances. Design: A cross-sectional, qualitative study with purposive sampling. Setting: UK dental teaching hospital. Participants: Twenty-six orthodontic patients aged 11–17 years. Methods: Patients participated in in-depth semi-structured interviews. All interviews were transcribed verbatim and analysed thematically. Results: Young people reported physical, practical and emotional impacts from their appliances. Despite these reported impacts, participants described ‘getting used’ to and, therefore, not being bothered by their appliance. Framework analysis of the data identified a multi-dimensional social process of managing everyday life with an appliance. This involves addressing the ‘dys-appearance’ of the body through physically adapting to an appliance. This process also includes psychological approaches, drawing on social networks, developing strategies and situating experiences in a longer-term context. Engaging in this process allowed young people to address the physical, practical and emotional impacts of their appliances. Conclusion: This qualitative research has identified how young people manage everyday life with an appliance. Understanding this process will help orthodontists to support their patients.

Full textAbstract:
Background: Information regarding the various factors that can influence the duration of orthodontic treatment has been investigated before; however, despite the increasing amount of evidence becoming available, controversy still exists. Therefore, this investigation was considered to be useful as additional information to the orthodontic literature. Aim: To determine factors associated with the duration of orthodontic treatment for patients with a Class II malocclusion treated with a functional/fixed appliance approach to treatment. Design: Retrospective, observational study. Setting: Orthodontic Department, Liverpool University Dental Hospital, UK. Method: Data were collected from the records of eligible patients. Inclusion criteria: Patients were included if they had: 1) Undergone a course of orthodontic treatment involving a first phase of treatment with the Twin-Block appliance between the 1st of January 2005 and 31st of December 2008; 2) A Class II dental malocclusion; 3) Required a functional/fixed orthodontic approach to orthodontic treatment; 4) Completed two phases of orthodontic treatment; 5) Records available in a satisfactory condition. Outcome measures: • Duration of the functional appliance phase of orthodontic treatment • Total duration of orthodontic treatment Results: The pre-treatment overjet was the only factor that had a statistically significant influence on the duration of the functional phase of the treatment (p= 0.016). The factors that were statistically significant predictors for the duration of the full course of orthodontic treatment were: the number of treating clinicians (p=0.001), the number of failed appointments (p=0.001), the chronological age of the patient (p=0.002) and whether the patient had extractions or not (p=0.021). Conclusions: 1. The only factor that had a statistically significantly influence on the duration of the functional phase of treatment was the overjet at the start of treatment (positive association). 2. The factors that had a statistically significantly influence on the total treatment duration were the: a) Number of the treating clinicians (positive association); b) Number of appointments the patients failed to attend (positive association); c) Chronological age of the patient (negative association); d) Presence or absence of dental extractions (positive association).

Previous issue date: 2011-04-26The aim of this prospective study was to investigate the ForsusTM s effects on the upper and lower central incisors. The sample consisted of 22 computed tomography from 11 patients (7 boys and 4 girls, average age 15,8 years), Class II malocclusion that were treated with ForsusTM at the clinic of the Orthodontics graduate program with a concentration area in orthodontics at the Methodist University of São Paulo. Cone beam computed tomographic were obtained from each patient at T1 (after the leveling phase and before the ForsusTM) and T2 (immediately after ForsusTM). To measure the distance between the root apex to the bone plate, the images were obtained with iCATVisionTM and examined with CorelDRAW X5TM. The cephalometric measurements IMPA and 1.PP were traced in images obtained with Dolphin 3DTM (Dolphin Imaging and Management Solutions, Chatsworth, EUA) with software Radiocef Studio 2 (Radio Memory, Belo Horizonte, Brazil). Systematic errors were estimated by paired t test (p<0,05), and casual errors were calculated according to Dahlberg s formula. The statistical analysis of the results was performed using the t test (p<0,05) to determinate the difference of T1 and T2 and to evaluate the correlation of the alterationsobserved the test of correlation of Pearson was made. The results demonstrated a significant increase (p<0,05) in IMPA and 1.PP, the root apex of lower incisors approached the lingual bone plate and the root apex of upper incisors approached the buccal bone plate. The treatment results of the ForsusTM proclined the lower central incisors and uprighted the upper central incisors.
O objetivo deste estudo prospectivo foi avaliar os efeitos do aparelho Forsus® nos incisivos centrais superiores e inferiores. A amostra constituiu-se de 22 tomografias computadorizadas de 11 pacientes (sexo masculino e feminino) idade média de 15,8 anos com má oclusão de Classe II que foram tratados com o aparelho Forsus® na clínica do programa de pós-graduação em Odontologia, área de concentração Ortodontia, da Universidade Metodista de São Paulo. As tomografias foram obtidas em dois momentos T1 (final de nivelamento e antes da instalação do Forsus® e T2 (remoção do Forsus®). Para avaliar a distância do ápice até a tábua óssea, as imagens a serem examinadas foram obtidas com o auxílio do viewer do próprio i-CAT® , o iCATVision® e examinadas com o CorelDRAW X5® já para as medidas cefalométricas IMPA e 1.PP as imagens cefalométricas ortogonais foram obtidas em proporção 1:1 com auxílio do software Dolphin 3D® (Dolphin Imaging and Management Solutions, Chatsworth, EUA) e em seguida examinadas com o software Radiocef Studio 2 (Radio Memory, Belo Horizonte, Brasil). Para a obtenção do erro intra-examinador foi feito o teste t de Student pareado para o erro sistemático e a fórmula de DAHLBERG para estimar a ordem de grandeza dos erros casuais e na análise estatística dos resultados utilizou-se: o teste t para a determinação das diferenças entres as fases de observação e o teste de correlação de Pearson para avaliar a correlação entres as alterações. Observou-se: um aumento significativo (p<0,05) tanto no IMPA quanto no 1.PP, aproximação do ápice dos incisivos inferiores da tábua óssea lingual, aproximação do ápice dos incisivos superiores da tábua óssea vestibular, uma correlação negativa muito forte entre o IMPA e a distância do ápice do incisivo até a tábua óssea lingual e uma correlação negativa moderada entre 1.PP e a distância do ápice do incisivo até a tábua óssea vestibular. Sendo assim o aparelho Forsus® no tratamento da Classe II teve como efeito: vestibularização significativa dos incisivos centrais inferiores, uma verticalização significativa dos incisivos centrais superiores, aproximação do ápice dos incisivos inferiores da cortical óssea lingual e aproximação do ápice dos incisivos superiores da cortical óssea vestibular.

Introduction: Successful treatment of class II Division 1 malocclusion is also implied to the long-term stability of treatment changes and many are the factors that can influence that. Objective: This research aimed to evaluate the long-term stability of the cephalometric changes obtained during Class II malocclusion correction with the MARA (Mandibular Anterior Repositioning Appliance) associated with fixed appliances. Methods: The treatment group comprised 12 patients who were evaluated at three stages: pretreatment (T1), posttreatment (T2) and long-term posttreatment (T3). The mean initial age of the patients was 12.35 years and the mean final age was 15.65 years. The mean age at the long-term posttreatment stage was 22.53 years and the mean long-term posttreatment period was 6.88 years. The control group comprised 12 subjects with normal occlusion and no orthodontic treatment with ages comparable to the treatment group at the posttreatment and long-term posttreatment stages. Intra-treatment group comparison between the three stages was performed with repeated measures analysis of variance (ANOVA), followed by Tukey tests. Intergroup comparison of posttreatment changes and normal growth changes of the treatment group were performed with t tests. Results: reduction of the maxillary protrusion and improvement of the maxillomandibular relationships remained stable during the long-term posttreatment period. Maxillary incisors inclination and overjet presented a tendency to relapse in relation to the control group Conclusions: Despite the different amount of growth potential, the reduction of the maxillary protrusion and maxillomandibular relationship improvement remained stable with no difference from normal occlusion behavior. Palatal inclination of the maxillary incisors and the overjet improvement showed a slight tendency towards relapse when compared to normal occlusion. Therefore, an increase of active retention time could be recommended to prevent that.Introdução: o tratamento bem-sucedido da má oclusão de classe II Divisão 1 está implícito na estabilidade em longo prazo das correções e muitos são os fatores que podem influenciar esta estabilidade. Objetivos: observando que a terapia com o aparelho MARA (Mandibular Anterior Repositioning Appliance) associado ao aparelho ortodôntico fixo mostrou-se eficaz na correção da Classe II, este trabalho estabeleceu como objetivo avaliar cefalometricamente a estabilidade em longo prazo das correções obtidas durante este tratamento. Materiais e métodos: foram analisadas as alterações durante e após o tratamento através das telerradiografias em norma lateral de 12 pacientes (09 meninos e 03 meninas) nas fases: inicial (T1), final (T2) e pós-tratamento (T3), com idade média inicial de 12,35 anos e 15,65 anos ao final do tratamento. A idade media no estágio de pós tratamento em longo prazo foi de 22,53 e o tempo de acompanhamento pós tratamento foi em media 6,88 anos. As alterações foram comparadas a um Grupo Controle com oclusão normal, não tratados ortodonticamente, com idades compatíveis ao grupo experimental nos estágios final e pós tratamento em longo prazo. Os dados obtidos foram analisados através da análise de variância (ANOVA) para medidas repetidas e o teste de comparações múltiplas de Tukey. As alterações ocorridas no período de póstratamento foram comparadas com as alterações do Grupo Controle durante o período correspondente utilizando o teste t independente. Resultados: Observou-se uma redução da protrusão maxilar, assim como, uma melhora das relações maxilomandibulares, as quais, permaneceram estáveis durante o período de póstratamento. A inclinação dos incisivos superiores e o overjet apresentaram tendência à recidiva em relação ao grupo controle. Conclusões: A redução da protrusão maxilar e melhora da relação maxilomandibular mantiveram-se estáveis, sem diferença estatisticamente significante do comportamento na oclusão normal. A retroinclinação dos incisivos superiores e a melhora do overjet mostraram uma ligeira tendência à recidiva quando comparada ao comportamento da oclusão normal. Portanto, um aumento do tempo de retenção ativo pode ser recomendado para evitar essa recidiva.

Objectives: To compare the skeletal, dentoalveolar and soft tissue effects of the AdvanSyncTM appliance with intermaxillary elastics in the correction of Class II malocclusions in growing patients.
Materials and Methods: A retrospective study was conducted using lateral cephalograms of patients taken pre-treatment (T1) and post-comprehensive orthodontic treatment (T2). 41 patients consecutively treated with AdvanSyncTM were compared to 41 similar patients treated with intermaxillary Class II elastics. All patients had significant growth potential during treatment, as assessed by cervical vertebral maturation. A comparison group was generated from historical databases and matched to the experimental groups for skeletal age, gender and craniofacial morphology. Treatment changes were evaluated between the time points using a custom cephalometric analysis generating 31 variables as well as regional superimpositions. Data was analyzed using one-way analysis of variance and Tukey-Kramer tests.
Results: The effects of AdvanSyncTM and fixed orthodontics (T2-T1) included maxillary growth restriction, protrusion, proclination and intrusion of mandibular incisors as well as mesialization of mandibular molars (p<0.01). The effects of Class II elastics and fixed orthodontics were similar to AdvanSyncTM, with the exceptions of less maxillary growth restriction and greater retrusion and retroclination of maxillary incisors (p<0.01). Significant mandibular growth stimulation, relative to untreated controls, did not occur with either modality.
Conclusion: AdvanSyncTM and intermaxillary elastics were effective in normalizing Class II malocclusions during comprehensive fixed orthodontics. AdvanSyncTM produced its effects through maxillary skeletal growth restriction and mandibular dentoalveolar changes. Class II elastics worked primarily through dentoalveolar changes in both the maxilla and mandible.October 2016

A malocclusion can be defined as ‘a deviation from the ideal that may be aesthetically or functionally unsatisfactory, with a wide range of occlusal traits’. Orthodontics is a constantly evolving specialty, with ever changing principles and techniques continuing to be developed. There has been huge progress in orthodontics in recent times, with changes in the types of brackets, archwire materials, and appliance systems (such as temporary anchorage devices and aligner technology). The key principles of orthodontics date back to 1899 when Edward Angle described ‘the key to a normal occlusion as the anteroposterior relationship between the upper and lower first molars’. In 1972, Lawrence Andrews described ‘six keys to an ideal static occlusion’. This was the basis of early orthodontic treatment planning. Knowledge of craniofacial development and growth is required as a foundation for understanding the aetiology of a patient’s malocclusion, to reach a diagnosis, and to plan orthodontic treatment. A basic understanding of the types of orthodontic appliances is beneficial (mainly fixed appliances, functional appliances, some use of removable appliances, and retainers). In addition to the management of a malocclusion, orthodontic treatment is often required in conjunction with other specialties, including oral and maxillofacial surgery, paediatric and restorative dentistry Key topics discussed in this chapter include: ● Fixed appliances ● Functional appliances ● Removable appliances ● Retention ● Index of treatment need ● Orthodontic assessment and diagnosis ● Cephalometric analysis ● Malocclusion ● Ectopic canines ● Dental anomalies.
