Abstract

The purpose of this study was to determine dental and
skeletal effects of the of Teuscher activator in treatment of Class
II Division 1 malocclusion cases. Sixteen patients (eight males and
eight females) with Class Division 1 malocclusion were selected for
this study. The mean age of the patients was 10 years 5 months.
All patients were treated with the Teuscher activator for one year.
Cephalometric radiographs and plaster study models were made at
two stages; before and after treatment by the Teuscher activator.
The cephalometric radiographs and the study models were analyzed
and the collected data were subjected to statistical analysis.
Statistical paired T test was done to determine the significant
difference between the pretreatment and posttreatment measurements.
Results: The SNA angle was significantly decreased (P = .002).
The SNB angle was significantly increased (P = 000). The ANB
angle was significantly decreased (P = 000). The mandibular plane,
palatal plane, and Y-axis angles (SN-MP, SN-PP. and Y-axis
respectively) were not significantly affected (P = .204, P =.705,
P = .041 and P = .064). Teuscher functional appliance could be
used successfully in treatment of Class II Division 1 malocclusion
cases.
