ABSTRACT: Class III malocclusion associated with skeletal anterior
open bite pattern in adults can be a challenging orthodontic problem, especially
for the nonsurgical treatment. Conventionally, several treatment alternatives
are available such as tooth extraction, molar intrusion, and absolute anchorage
system or orthognathic surgical correction. Although correction with surgery
may be the most effective and stable way, many patients refused surgical
treatment plan because of the costs and traumas it may bring. We reported a
nonsurgical orthopedic treatment of 22-year-old male with severe skeletal anterior
open bite, dental Class III malocclusion, posterior crossbite and a high
mandibular plane angle. The patient refused surgery and extraction. So we formulated
a treatment plan consisting of using rapid palatal expansion appliance to
expand the maxilla, standard edgewise brackets to align the teeth, Class III
elastics to correct the canines, premolars, and molars relationship, reverse
curve of the nickel-titanium wire combined with anterior vertical elastics to
intrude molars and correct open bite. In this case, without suffering of surgery, the posterior crossbite was ideally corrected, and ideal overjet and
overbite relationships and functional occlusion were all achieved. The
patient obtained satisfactory occlusal as well as functional and stable
results.
