A pre and post treatment comparison of class ii division 1 malocclusion cases treated with pre-adjusted edgewise appliances using the par index

AUTHOR(S): Dr. Sunita Saini
ABSTRACT:
PAR index provides a single summary score for all the occlusal anomalies and may be used for all types of malocclusions, treatment modalities and extraction/non extraction cases. The score provides an estimate of how far a case deviates from normal & the difference in score for pre & post – treated cases reflects the perceived degree of improvement & therefore the success of treatment. The aim of the study is to assess the success of treatment in class II Div. 1 cases by PAR index, treated in Department of Orthodontics, RUHS college of Dental Sciences Jaipur. Sample included 100 cases of Class II Div. 1 malocclusion treated with pre adjusted edgewise appliances which were divided into 2 groups, group A (extraction) and group B (non-extraction). The same were evaluated pre and post treatment.
Material: Pre & Post treatment study models of selected cases, PAR index guidelines.
Method-Class II Div. 1 pre treatment study models of patients were assessed by the PAR index and the deviation from the normal occlusion determined by the PAR index.
A comparison of pre and post values in PAR index recorded. It serves as an indicator for correction achieved in malocclusion in post treatment cases.
Results: Results showed significant pre and post treatment difference (p< 0.05) between group A and group B using PAR index, in terms of over jet and overbite.
Conclusion: All the cases irrespective of extraction or non extraction mechanics showed significant overall improvement after treatment with pre adjusted edgewise appliance.
