'Maturational Patient Report' supplied by GrowthTek clearly
assists and guides the clinician in formulating a well-timed treatment
plan. It is very important not to rely on chronologic age in
determining whether a face-mask appliance (reverse head-gear)
will benefit the patient.
The face-mask works best during the very early adolescent period
of development or earlier during mid-to-late childhood. It is
theorized that early intervention is best because the maxilla is
significantly smaller in size and because the mid-palatal suture is
not completely fused. The movement of Point A forward is facilitated
by labial root torque being placed on the upper incisor teeth.
As you can see on the following charts, significantly more forward
maxillary movement is achieved during early adolescence. The relative
success of treatment is diminished as adolescence proceeds, with
significantly less success during late late adolescence. In other words,
success with face-mask therapy is not dependent on maxillary growth
How is orthodontic face-mask treatment best timed?

section of this web site for specific clinical information regarding
maturational timing of treatment. Also refer to the 'Background
Information' section of this web site for additional information.
