What are your thoughts regarding the stability of open-bite surgery?
Surgical open-bite closure stability is controversial. Denison and colleagues published a paper in which 43% of their 28 patients undergoing surgical closure of open bite had recurrence of the open bite; 22% of the patients actually had no incisor overlap at the longest-term follow-up. They concluded that persistent etiologic factors caused recurrence of the open bite. We have done a similar study at UCLA in which we matched our patient numbers and length of follow-up with the Denison patient group. In our study, no patient had open-bite relapse at final follow-up. The basic difference between the Denison group and our group was the type of orthodontic surgical preparation. The Denison group used continuous-archwire surgical preparation to match the upper and lower arch widths, archforms, and planes of occlusion.
