Abstract

Introduction: About 1/3rd of orthodontic patients have class II malocclusion and different treatment options are available for the treatment. It is the goal of orthodontics to give an ideal smile to the patients and therefore this study
was conducted to compare the outcomes of different treatment protocols.
 
Materials & Methods: A cross-sectional study was conducted using pretreatment and post-treatment photographs, cast and post-treatment radiographs of 135 subjects being divided into 3 treatment protocols: Upper premolar extraction (UPE), clark’s twin block (CTB) and class II elastics (C2E) treatment modality. The cases were analyzed using ABO-OGS, IOTN and PAR index. Wilcoxon-Signed Rank test was used to compare the pretreatment and post-treatment malocclusion scores. Mann-Whitney U test and Kruskal-Wallis test were used to compare the scores among treatment modalities. p≤0.05 was kept as a level of significance.
 
Results: The ABO index indicated that more failure with C2E followed by CTB and UPE (40, 33.3 and 20%) respectively. PAR and IOTN showed statistically significant improvement.
 
Conclusion: All treatment modalities are effective however; C2E has more failure cases as compared to other modalities.
