Aim: The aim of this study was to know the relaps prevalence after Orthodontic treatment with fixed Orthodontic appliance using PAR index. Methods: Sample of this study were 24 dental impression post treatment and 24 dental impression during the research. The method of this study was descriptive analitic with Shapiro-wilk test to get the data homogenity and normality, Paired T test to analyze the difference of paired data with normal distribution. Results: Result showed saphiro wilk test after bracket removal score and the score when this study was performed was p>0,05 which means the distributione of data was normal. Paired sample t test showed the result after bracket removal score and the score when this study was performed was p<0,05 which means there were significance differences. Conclusion: There were significance difference between PAR index after bracket removal and when this study was performed. This showed that there was prevalence of mild relapse after fixed orthodontics treatment
