  • Orthodontic Camouflage Treatment of Skeletal Class III Malocclusion with Mandibular Bite Turbo Application
    CASE REPORT East J Med 25(2): 321-326, 2020 DOI: 10.5505/ejm.2020.57060 Orthodontic Camouflage Treatment of Skeletal Class III Malocclusion with Mandibular Bite Turbo Application Saadet Cinarsoy Cigerim Department of Orthodontics, Faculty of Dentistry, Van Yuzuncu Yil University, Van, Turkey ABSTRACT Treatment of skeletal class III malocclusions is difficult malocclusions. The treatment of skeletal class III malocclusions varies according to the jaw and the growth period of the anomalies. Adult individuals whose growth is over are treated with fixed orthodontic mechanics or orthognathic surgical approaches. If skeletal class III malocclusion is not severe and does not constitute a problem aesthetically, camouflage treatment can be done with fixed orthodontic mechanics. This case report presents the results of orthodontic camouflage treatment and treatment applied to a skeletal class III malocclusion female patient with chronological age of 17 years and 9 months and skeletally in the Ru period. The molar relationship of the patient with a slightly concave profile is Angle class III. In cephalometric examination, skeletal class III malocclusion was detected (ANB angle= -6). At the end of treatment, a Angle class I relationship and a smooth soft tissue profile were obtained.

  • SPACE ANALYSIS Space Analysis Is a Process That Allows an Estimation of the Space Required in Each Arch to Fulfil the Treatment Aims
    أ. د. أكرم فيصل الحويزي 5th Year Lec. No. 12 SPACE ANALYSIS Space analysis is a process that allows an estimation of the space required in each arch to fulfil the treatment aims. It helps to determine whether the treatment aims are feasible, and assists with the planning of treatment mechanics and anchorage control. Space planning is carried out in 2 phases: 1- to determine the space required for relief of crowding, overjet correction and creating space for any planned prostheses. 2- calculates the amount of space that will be created during treatment by molar distalization, arch expansion, inter-proximal stripping …etc. Before undertaking a space analysis, the aims of the treatment should be determined as this will affect the amount of space required or created. Space analysis can act only as a guide, as many aspects of orthodontics cannot be accurately predicted, such as growth, the individual patient’s biological response and patient compliance. MIXED DENTITION ANALYSIS: In mixed dentition space analysis, mesiodistal width of unerupted canine and premolars is predicted so that discrepancy between space available and space required for these teeth in the dental arch can be determined. There are three main approaches to mixed dentition space analysis: a) Measurement from radiographs: The widths of unerupted canine and premolars is estimated using proportionate measurement from radiographs, which takes into account any magnification. The widths of permanent canine and premolars are measured directly from dental radiographs. The width of a deciduous molar is measured from the radiograph and from the dental cast and the following equation is used: 푼풏풆풓풖풑풕풆풅 풕풐풐풕풉 풕풓풖풆 풘풊풅풕풉 퐷푒푐푑푢표푢푠 푚표푙푎푟 푡푟푢푒 푤푑푡ℎ = 푈푛푒푟푢푝푡푒푑 푡표표푡ℎ 푟푎푑표푔푟푎푝ℎ푐 푤푑푡ℎ 퐷푒푐푑푢표푢푠 푚표푙푎푟 푟푎푑표푔푟푎푝ℎ푐 푤푑푡ℎ Then the combined widths of the permanent canine and premolars is compared to the combined widths of the deciduous canine and molars.

In these cases, the correction of class II can be hindered by molar distalization, obtained with ‘no-compliance therapy’ that involves the use of appliances which minimize the need for such co-operation and attempt to maximize the predictability of results. The aim of this review was to outline the effectiveness of no-compliance fixed orthodontic devices in the molar distalization. After selection according to the inclusion/exclusion criteria, 16 articles from 2000 to 2019 were qualified for the final analysis. The literature shows various no-compliance fixed devices whose effect is to distalize the maxillary molars. The present revision allows to conclude that there is a need to increase the number of studies, especially with regard to the most recently introduced devices in the literature. The analysed studies allow to hypothesize that these appliances act with a minimal variability of molar distalization and disto-inclination among them, although different effects among the appliances can be observed as regards to the anchorage.
