Components of adult Class III open-bite malocclusion

Stability Following Combined Orthodontic-surgical Treatment for Skeletal Anterior Open Bite – a Cephalometric 15-Year Follow-up Study

“…Some authors [10,11] believe that preoperative incisor extrusion increases the incidence of relapse after surgery. Others do not, such as Lo & Shapiro [25], who found no significant difference in the amount of relapse -they maintain that preoperative extrusion of the incisors does not appear to affect the stability of open-bite correction.…”

Classification of Anterior Open Bite Using Individualized Cephalometry

“…Ellis & McNamara [7] and Tsang [38] have also reported a frequent combination of open bite and Angle Class III.…”

Combined Treatment of Open Bite – Long-term Evaluation and Relapse Factors

“…While Moldez et al [25] and Swinnen et al [29] were much more likely to detect relapse after posterior maxillary impaction, Arpornmaeklong et al [1] reported a greater tendency to relapse in the mandible. Ellis et al [7] emphasized the prevention of masseter-sling expansion to allow for more relapse-free autorotation of the mandible. This concurs with our study's results, namely, that facial height should not be increased if a relapse is to be prevented.…”
