AIM: To evaluate the orthodontic treatment outcome in patients with Class II, division 1 malocclusion using the PAR index and to investigate factors determining treatment outcome. DESIGN: Retrospective analysis. SETTING: This study constitutes part of the first author’s research study realized in 2000 as part of the requirements of the Postgraduate Orthodontic Program of the Aristotle University of Thessaloniki. MATERIAL AND METHODS: Dental casts of 64 patients (31 boys and 33 girls) (mean age: 12.2±1.7 years) with Class II, division 1 malocclusion and overjet ≥ 4 mm before and immediately after orthodontic treatment. Patient records were taken from the files of the Postgraduate Orthodontic Clinic, Aristotle University of Thessaloniki. INTERVENTIONS: Two groups were formed according to the treatment method followed. Forty-two patients (group I) received non-extraction treatment with activator or/and headgear combined with fixed appliances and 22 patients (group II) were treated with premolar extractions and fixed appliances. MAIN OUTCOME MEASURES: Patients’ dental casts were evaluated before and after treatment using the PAR index. Statistical analysis of data was performed by means of the SPSS 10.0 software and the level of significance was set at p≤0.05. After a two weeks interval, double measurements in 30 dental casts were performed in order to estimate the method’s error. RESULTS: Malocclusion improved in 84.5% of the sample (87.4% in the non-extraction group and 79.9% in the extraction group). Comparison between the two groups showed that differences were statistically significant only before treatment. Treatment outcome was correlated only to the severity of the initial malocclusion. CONCLUSIONS: Great improvement was observed in all patients regardless of the therapeutic modalities used and tooth extractions. |
