ᕣ When treating a patient with a steep mandibular plane, avoid extruding posterior teeth. ᕤ When the posterior teeth have a strong Class I interdigita-tion, patients seldom relapse after VektorPRO correction. In addition, you and your patients and their parents will be able to see fast improvements in the face and occlusion. Especially since corrections occur in 4 to 6 months. There are no lab fees, an easy instal-lation and light continuous forces make the VektorPRO an efficient Class II corrector that sets a new standard for treatment. The results being produced when patients use the VektorPRO are unprecedented in terms of treatment time and patient comfort.
