    Evaluation of Effects of Orthodontic Malocclusions on Duration of Treatment with Regard to the Labor/Cost Concept
    (Aves Press Ltd, 2015) Ersoz, Mustafa; Toy, Ebubekir; Cakir, Ezgi
    Objective: The purpose of this study was to compare the treatment duration and fees of Angle Class I, II, and III malocclusions. Methods: In this retrospective study, the samples were selected from the files of 450 patients treated at the Department of Orthodontics, Inonu University. The files of patients whose treatments were completed as planned were included in the study. In total, 387 patients (137 males and 250 females) met this criterion (mean age: 14.65 years). Patients were divided into three groups: treatment duration less than 20 months (group A), between 20-30 months (group B), and more than 30 months (group C). Analysis of variance (ANOVA) and t-tests were conducted to determine the difference in treatment duration between the groups and sexes. Results: From the 387 patients, 78 (20.2%) had Class I, 254 (65.6%) had Class II, and 55 (14.2%) had Class III malocclusion. The average treatment duration was 27.82 months (males: 31.82 months, females: 29.33 months). There were no statistically significant differences between the sexes according to the treatment duration. The average treatment duration according to malocclusions was 26.24 months for Class I, 28.22 months for Class II, and 28.21 months for Class III. The distribution of the groups according to treatment duration was as follows: Group A: 72 (18.6%), Group B: 173 (44.7%), and Group C: 142 (36.7%) patients. The relationship between the treatment durations and Angle classifications was not statistically significant (p=0.216). Conclusion: This study showed that there were severe anomalies and problematic malformations within each Angle classification because no statistically significant difference among the malocclusion classes in terms of the duration of treatment was found. Therefore, besides the anomaly type, the treatment duration and effort put into the work should also be taken into consideration in determining the treatment charge.

    Treatment of Class II malocclusion with mandibular skeletal anchorage
    (Mosby-Elsevier, 2017) Cakir, Ezgi; Malkoc, Siddik; Kirtay, Mustafa
    Introduction: The aim of this case report was to present the dentofacial changes obtained with bone anchorage in a Class II patient with moderate to severe crowding. Methods: A boy, aged 14.5 years, with a dolichofacial type, convex profile, and skeletal and dental Class II relationships was examined. After evaluation, functional treatment with bone anchorage and 4 first premolar extractions was decided as the treatment approach. Miniplates were placed on the buccal shelves of the mandibular third molars. The hook of the anchor was revealed from the first molar level. After surgery, the 4 first premolars were extracted to retract the protrusive mandibular incisors. The maxillary and mandibular first molars were banded, and a lip bumper was inserted to apply elastics and to help distalize the maxillary first molars. Orthodontic forces of 300 to 500 g were applied immediately after placement, originating from the miniscrews to the hooks of the appliance to advance the mandible. Results: After 20 months of treatment, the patient had a dental and skeletal Class I relationship, the mandible was advanced, the maxilla was restrained, and overjet was decreased. Conclusions: The combination of a bone anchor, Class II elastics, and an inner bow is a promising alternative to functional treatment, along with extractions, in Class II patients.
