We were recently educated by Dr. Frank Spear
on treatment options for Class III patients. These patients are usually offered
3 alternatives: maxillary or mandibular orthognathic surgery, orthodontics, or
restorative treatment.
If the patient will
not accept the first two options, the doctor must develop a functional,
restorative occlusal scheme. Dr. Spear offers advice based on his extensive
experience. Class III relationship allows the patient to slide into an
exaggerated protrusive position without anterior interference. This slide can
become habitual. When the patient is restored to normal occlusion, with
standard overjet and overbite, this habitual slide will meet a major
interference, leading to wear, parafunction, or worse. Dr. Spear suggests that
the best occlusal scheme is end-to-end with little-to-no overjet, and minimal
anatomy in the posterior. At this point, the patient has maneuverability and
stable occlusion.
