PERUBAHAN PROFIL WAJAH PASCA 6 BULAN PERAWATAN ORTODONTIK CEKAT (STUDI SEFALOMETRI LATERAL DI RSGM UMY)

Background : Orthodontic treatment is a form of treatment in dentistry that serves to improve mastication, phonetics, and aesthetics. Orthodontic treatment is divided into two types, fixed orthodontic appliances and removable orthodontic appliances. Changes that occur during orthodontic treatment can be divided into three stages: stage 1, leveling and alignment; stage 2, working; stage 3, finishing. Dentoskeletal changes due to orthodontic treatment can be evaluated and analyzed by cephalometry. Cephalometric analysis can be analyzed using Steiner analysis. Steiner analysis is divided into three examinations, which is skeletal, dental and soft tissue. Purpose: The aim of this study is to know facial profile changes after 6 months of fixed orthodontic treatment using the Steiner method, lateral cephalometric study at RSGM UMY. Methods: This type of research is a longitudinal prospective with a cohort study design. The population in this study were 7 people who performed lateral cephalometric radiographs with the inclusion and exclusion criteria, and obtained from the medical records of fixed orthodontic patients at RSGM UMY in March 2021. The sampling technique used in this study was total sampling. Data analysis used normality analysis using Saphiro Wilk and Wilcoxon test was performed because the data distribution was not normal. Result: The subjects in this study were 7 people who performed lateral cephalometric radiographs. However, only 5 people were willing to perform lateral cephalometric x-ray before and after 6 months of fixed orthodontic treatment. Based on the research conducted, it was found that there was no change in facial profile before and after 6 months of fixed orthodontic treatment at RSGM UMY, this was indicated by the result of Sig (2-tailed) 0.317 or p > 0.05. Conclusion: There is no change in facial profile before and after 6 months of fixed orthodontic treatment at RSGM UMY.
