Overview
Brief Summary
In this study it was aimed to examine the changes in mandibular bone after functional treatment by using fractal dimension (FD) and cortical thickness (CT) analysis.
Detailed Description
In this study it was aimed to examine the changes in mandibular bone after functional treatment by using fractal dimension (FD) and cortical thickness (CT) analysis. The study will perform on 42 mandibular retrognathia cases. The treatment group (T), comprised of 30 cases treated with functional appliance for one year in puberty. The control group (C) consists of 12 patients who had insufficient oral hygiene; didn't take any orthodontic treatment for one year. FD and CT analysis will evaluate for both sides. FD measurements will perform on processus condylar, antigonial notch, and ramus regions in the panoramic radiographs. Paired t-test will apply to analyze all between groups (before (T1) and after treatment (T2), before (C1) and after (C2) control). Also, independent t-test wişll use to determine whether there was any difference between the treatment group (∆T=T2-T1) and the control group (∆C=C2-C1).

Outcomes
Primary Outcomes
The effect of functional treatment on the cortical structure of the mandible will be investigated by measuring cortical thickness.
Time Frame: for one months from the beginning of the study
the effects of functional treatment with cortical thickness to cortical bone structure
Thanks to fractal dimension analysis, the effect of functional treatment on the trabecular bone structure of the mandible will be examined.
Time Frame: for one week from the beginning of the study
the effects of functional treatment with fractal analysis to trabecular bone structure
