Treatment of different patients addressing their orthodontic problems (specially vertical problems) are presented in this chapter. envelope of orthodontic tooth movement has well increased and less emphasis needs to be placed upon patient s compliance. Retrospective analysis of patients who underwent corticotomy as part of their orthodontic therapy for treatment of ⦠Orthodontic treatment goals can be divided into five categories: facial esthetics, dental esthetics, functional occlusion, periodontal health, and stability. The envelope of discrepancy denotes the limits of orthodontic treatment possible with different modalities, namely orthodontics alone or orthodontics with orthopaedics and surgical correction. Consider the distance that incisor teeth can be repositioned orthodontically. To assess whether concomitant particulate bone grafting makes a difference in the ability to safely orthodontically reposition teeth outside the bony envelope after corticotomy. Guidelines for this are provided by the âenvelope of discrepancyâ (image 2). Fry Orthodontic Specialists is an expanding, multi-office practice in the Kansas City metropolitan area. Founded by Dr. Bob Fry in 1977 as part of a larger group, it split off as a thriving single-doctor practice in 1987. 2.
