Abstract:

A Removable functional appliance is composed of polished acrylic shields and stainless steel wires prescribed for patients with more pronounced class II malocclusion or open bite. These appliances work comfortably with a patient’s inherent growth to produce the desired Skeletal or Dental development. It can be achieved by dentoalveolar effects, alteration of soft tissue and utilisation of greater Mandibular growth potential. The commonly used Removable functional appliances are Twin Block appliance, Activator, Bionator, Frankel appliance, etc. This study aims to assess the frequency of the usage of removable functional appliances in a hospital based set up. The data of patients undergoing Removable functional appliance therapy was retrieved from the case sheets of the patients.The collected data was tabulated in Excel and statistically analysed with the help of SPSS software. From the results obtained, Twin block appliance was the most prevalent Removable functional appliance with a frequency of 60.6%. Frankel appliance and Activator each had a frequency of 9.1%. Twin block appliances were mostly preferred for males than females whereas Activator is preferred mostly for females. Based on the age, Twin block appliance was preferred for the age group 10-15 years, Frankel appliance for 5-10 years, Activator and Other appliances for 10-15 years. Therefore, within the limits of this study, we observed that Twin block appliance was the most preferred Removable functional appliance used in the management of Class II malocclusion and the most common age group receiving appliance therapy is 10-15 years.

Abstract:

Background/Aim. Functional appliances can be used effectively in the treatment of skeletal Class II/1 malocclusions. The best treatment results are obtained during active period of facial growth when skeletal, as well as dentoalveolar, changes occur. In comparison with removable functional appliances, such as activator, that are effective only during adolescent period of growth, the Herbst fixed appliance is also successful at the end of the growth period. It also offers a shorter treatment time and a patient compliance is not necessary. The aim of this study was to analyze and compare dentoalveolar changes in the group of young adult patients with Class II/1 malocclusion treated with the Herbst appliance and an activator. Methods. The sample for this study consisted of 50 patients of both sexes, 14-21 years of age with Class II/1 malocclusion. For estimating the effect of functional appliances used, the following cephalometrics parameters were determined: inclination of the upper and lower incisors, interincisal angle, antero-posterior molars relationships, overjet and overbite. The results obtained were statistically tested. Results. The cephalometric findings after the treatment indicated retroinclination of upper incisors (average value of 9?) and proclination of lower incisors (average value of 7?), mostly expressed in the patients treated by Herbst appliance (p < 0.001). Increased overjet and distocclusion were completely corrected in the group of patients treated with the Herbst appliance, while the correction of malocclusion in the activator group was only partially accomplished. No changes in the overbite were noticed at the end of the treatment in both groups. Conclusion. The results of this study revealed that the Herbst appliance is more effective in the treatment of Class II/1 malocclusion in young adults in comparison with the activator.

Abstract:

The purpose of this study was to evaluate the skeletal and dentoalveolar effects and optimal timing for treatment of class II malocclusion with functional appliances in children and adolescents.A group of 30 patients with class II malocclusion were divided into 3 groups according to their use of functional appliance: Twin block, Activator, Fränkel appliance. The group was also divided into 2 groups according to the cervical vertebrae maturation method. Lateral cephalometric radiographs were analyzed pretreatment (T0) and posttreatment (T1). Among the functional appliances, treatment with Twin block and Activator showed significant increase in the length of the mandible (Co-Gn) and the lower anterior facial height (ANS to Me), whereas the overjet and overbite were significantly reduced. Treatment with Fränkel appliance showed significant improvement in the relationship of maxilla and mandible. In addition, if the functional appliance was used during the period of pubertal growth peak, there was a significant increase in mandibular length, improvement in the relationship of maxilla and mandible, labial inclination of lower incisors and decrease in overjet compared to the treatment before pubertal growth peak. Therefore, this study indicates that using functional appliances for patients with class II malocclusion is effective and the optimal timing for using functional appliances is during pubertal growth peak.

Abstract:

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

Abstract:

Myofunctional appliance are considered by many authorities orthopedic in nature, influencing the facial skeleton of the growing child in the condylar and suture areas. They also exert an orthodontic effect on the dent-alveolar area. Among these activator is the most well-known myofunctional appliance. The article describes the myofunctional appliance and its technique training, design, steps in preparation of Class II and Class III activator in sequential stages with illustrated case reports, treating class III molar relationship with crowded arch in maxilla and anterior cross bite. The Author acknowledges that the article is summarized from the lectures, handouts during his postgraduate studies in Kyushu University and Hiroshima University, Japan and from his experience from Dhaka Dental College and private practice at Ortho Dental Care. This article is a continuation of the series of technique training in orthodontics especially for the post-graduate trainees as well as for the practitioners who will learn and practice functional appliance specially activators. Once again, I believe that post-graduate trainee doctors, faculty members, private practitioners and all other concerned will find this article as a guide line during their training as well as in their professional practicing period.
