Presentation Summary

 The residual A-P correction will have to wait
until the patient reaches the pubertal growth
spurt; it has been shown that A-P correction
from the mandible is best achieved during the
peak pubertal growth spurt.
Molar Distalization
 There are many different appliances for molar
distalization: the sliding jig, ACCO appliance,
Wilson molar distalizer, pendulum appliance,
distal jet, and coil spring.
 One of the major side effects of molar distalization is anchorage loss.
 Molar distalization is more efficient with the
help of skeletal anchorage devices. Dr. Ngan's
graduate clinic utilizes the bone-borne
expander sideways.
Case #2: 16-Year-Old Female
 Diagnosis: Class II on right side, mild skeletal
dental asymmetry, thin upper lip and flat profile, severe mandibular curve of Spee, crowding of lower incisors, thin biotype.
 Treatment considerations: Correct unilateral
Class II molar relationship and resolve mild
crowding without excessive proclination of
the incisors.
 Treatment rendered: Comprehensive orthodontic treatment with straight wire appliance
and self-ligating bracket system. Light Class II

elastics (2 oz.) from the start of treatment.
Open coil spring with half activation (halfbracket distance of OCS). After engaging 7's,
still use 2 oz. Class II elastics for U3 to L7. Finish
and stabilize with U/L stainless steel wires.
 Tips: Dr. Ngan highlights the significance
of using the stainless steel wires for at least
three to four months; this is critical for
post-treatment stability and will help with
arch coordination for improving buccal interdigitation.
Removable and Fixed Functional Appliances
 Functional orthopedic treatment is defined as
the use of orthopedic tools to influence the
skeleton of the growing child in the condylar
and sutural areas to achieve skeletal improvement.
 Removable functional appliances include the
activator, bionator, and Frankel regulator;
these appliances require patient compliance.
 Fixed functional appliances, including MARA,
Forsus, and Herbst, are more popular in the
U.S. because compliance is not an issue.
 These appliances transmit muscular forces to
guide the growth process and eruption of
teeth by utilization, activation, and inhibition
of natural forces that signify the growth and
eruption potential.
