A prospective study was carried out with the purpose of comparing the results of two treatment strategies for deep overbite correction. The sample comprised 27 Class II, Division 1, with deep overbite cases (age 11 to 15 years). One group was treated with a continuous arch wire technique (0.01 6”nickel-titanium wire with reverse curve of Spee); in other group, the segmented arch technique (Burstone) was used for correction of vertical malocclusion; a control group of nine cases was used. Metallic implants were used for superimpositions. Forty five degrees cephalometric radiographs were used for evaluation of lower first bicuspids and first molars. These radiographs were taken before and immediately after leveling of lower arch. Statistical analysis was performed on the colected data. There was no significant difference between the three groups on lower first bicuspids. Lower first molars crowns were not influenced by these two treatments. However, the molar root points were restricted in their normal eruption.
