ABSTRACT
<p><b>OBJECTIVE</b>The aim of this study was to investigate the effects of the pendulum appliance in treating dental Class II patients with various vertical growth patterns.</p><p><b>METHODS</b>The samples (n = 30) were divided into three groups equally based on their FMA. Pretreatment and post-treatment cephalometric radiographs were taken to measure the changes.</p><p><b>RESULTS</b>The amount of upper molar distalization in the low-angle group was the fewest, and that in the high-angle group was the most. Upper molars had been intruded insignificantly. The amount of anchorage loss at the first premolars and overjet increased at incisors was different in the three groups. The biggest change happened in the low-angle group, and the smallest in the high-angle group.</p><p><b>CONCLUSION</b>The results of this study showed that pendulum appliance could move the upper molars distally in a short period of time. The upper molars in different groups were intruded insignificantly. Pendulum appliance could be used to move the upper molars distally in high-angle cases.</p>
