“…However, an additional benefit of the long-term use of an LLA is achieving and maintaining nearly ideal alignment of the lower incisors with selective extraction of the primary teeth without any additional appliances. 6,13 In a previous study, about one-third of patients who were treated with this approach did not receive further treatment in the permanent dentition. 13 As with any retrospective study, there were some limitations that should be noted.…”

“…A full description of the original sampling strategy was reported elsewhere. 13 The main inclusion criteria were the availability of both lateral cephalometric radiographs and study casts at the following two time points: before phase 1 treatment in the early mixed dentition (T1) and at the end of LLA therapy (T2; evaluation for phase 2) in the permanent dentition after the mandibular second molars erupted. Of the 137 patients who had complete records, 98 patients received LLA treatment with or without treatment in the upper arch (LLA group), and 39 patients did not receive any treatment in the lower arch (no-LLA group).…”

Objectives To investigate the effects of long-term use of the lower lingual arch (LLA) on the sagittal and vertical positions of the permanent lower incisors and first molars. Materials and Methods The sample consisted of 98 patients who were treated with an LLA (LLA group) and 39 patients who were treated without an LLA (no-LLA group). The positional changes of the lower incisors and first molars were analyzed after performing mandibular structural superimpositions on lateral cephalometric radiographs taken before treatment (T1) and at the end of LLA therapy (T2). The mean ages at T1 and T2 were 8.5 years and 13.2 years, respectively. Study casts were analyzed to quantify arch dimensional changes. Results Mesial movement of the lower molar cusp was similar between the LLA and no-LLA groups, but the vertical position was slightly greater at T2 in the LLA group. In the LLA group, there was a molar tip-back effect, and the lower incisors were proclined 4.2° more than in the no-LLA group. Arch perimeter decreased 3.6 ± 2.6 mm without an LLA and 0.97 ± 3.7 mm with an LLA. Intercanine and intermolar widths both increased about 1 mm more with an LLA (P < .0001). Conclusions The LLA does not seem to restrict mesial movement and vertical eruption of the lower incisors and molars in the long term. The LLA effectively preserves the arch perimeter at the expense of a slight lower incisor proclination.

“…He did not even mention about overjet and overbite. He only considered the sagittal plane in his classification Though there are ample amount of classifications given in the field of orthodontics, for classifying the relation between class II dental arches, there is more to contribute towards the classifications, as none of the classifications describe the extent to which malocclusion is present and the how to perform treatment planning of such malocclusion [9]. There are the cases where patient present with end-on molar relationship, as for now these cases are included in class II malocclusion but treating these patients as class II becomes difficult as there can be a notable difference between the presentation of malocclusion [10].…”

“…In class II malocclusion position of both upper and lower anterior teeth becomes very important and relation i.e overjet has to be established for proper diagnosis and treatment planning. Today, no such data is available for quantifying overjet in class II malocclusion which would prevail in treatment planning [9]. Considering the importance of overjet and overbite a new classification is to be formulated.…”

Background: It is important to quantify class II malocclusion for proper diagnosis of the case and adjusted treatment will aid in successful correction of malocclusion. Hence, the study will aid for proper treatment planning by classifying class II malocclusion established on the amount of overjet, overbite, distance and relation of maxillary and mandibular first molar and the relationship of canine and molar. Objectives: To grade Class II malocclusion in form of overjet and overbite. Materials and Methods: Patients visiting Department of Orthodontics and Dentofacial Orthopedics, Sharad Pawar Dental College, Wardha, having class II malocclusion will be chosen. The chi square test, student's paired and unpaired t test, and descriptive and inferential statistics will be used in the statistical analysis. Expected Results: The outcome after conduction of the study is expected to have more patients with Type 1 overjet and Type B overbite kind of Class II malocclusion. Conclusion: The establishment of this new classification will aid in concise analysis and proper treatment planning of Class II malocclusion thereby enhancing the esthetics and functional stability for the patient comfort.
