| Abstract | |
The objective of this study was to compare the treatment time of bilateral complete Class II malocclusion with and without crowding treated with four premolar extractions, The sample was selected from arquive of beginning models and pastes of pacients treated at Bauru Dental School, department of Orthodontics. The selected sample was composed by 57 patients and divided into two groups. Group 1 presented no crowding or crowding 0-3 mm was composed by 23 patients being 11 male and 12 female with a mean age of 13,13 years (minimum age 10,67 and maximum age 18,25). Group 2 presented crowding 4 mm or more was composed by 34 patients being 19 male and 15 female with a mean age of 13,07 years (minimum age of 11,08 and maximum age of 18,33). To compare treatment times between groups, t test was performed. Results demonstrated that there was not significantly difference in treatment times of group 1 (2,51 years) and 2 (2,49 years). Thus, the results support the idea the principal factor responsible for similarity treatment times is the need of the molar relationship correction, which is similar in both groups. (AU) | |
