-Jane lost the fight with her hair dryer that morning!
-She had a “Class II” skeletal facial profile. This was noticeable by her lower jaw that was proportionally positioned too far back. It gave her a “V” shaped or “pointed” facial appearance. 

Patient Review:
Head photos reveal two details:
Over 50% of the population shares this facial characteristic. Most parents will notice another feature often associated with “Class II” facial profiles, a dental bit “overjet”. The following photos show the patient upper protruding dentition. 
Treatment Consideration: 
Patient had a “canine tooth” (high in her maxillary upper jaw) that didn’t have enough arch space to come down. 
Patient seemed to have a severe overjet (upper teeth too far forward) and an overbite (upper teeth too far down). Diagnosis confirmed that it wasn’t the patient’s upper teeth that were too far forward but her lower teeth along with her lower jaw that were too far back.  

A “Schwartz” expansion appliance was first used to guide the growth of Jane’s upper dental arch laterally (sideways). 

The “Schwartz” appliance fitted nicely behind the patient’s upper teeth. 
Jane wore it from February 10th to August 13th, about 6 months. 

On August 13 a second removable appliance was used: The “Twin Block”
The “Twin Block” consists of two halves, one for the upper arch and one for the lower arch. Upon closure, the “Twin Block” causes the lower jaw to slide forward thus closing the “overjet” protrusion. 

Finally, “Speed Braces” were used to finalize the “Twin Block” pre-defined dental occlusion and to provide esthetic teeth position.

Except for a minor discrepancy on her upper left Canine, Jane’s teeth are nicely positioned and in good occlusion. 

Jane’s lower jaw was brought forward in treatment to give her beautiful facial esthetics and a healthier jaw placement.
