%X objectives: the purpose of this study was to compare the effects of a differently designed functional appliance (r-appliance) and the anterior inclined bite plate (aibp) in class ii division i (cl ii div i) cases. material and methods: fifty patients (28 girls, 22 boys) were chosen for the study: 25 patients (13 girls, 12 boys) with mean age of 10.4¡À0.8 years were treated with r-appliance for 11¡À2 months, the other 25 patients (15 girls, 10 boys) with mean age of 9¡À1.2 years were treated with aibp for 10¡À2 months. all patients had cl ii div i malocclusion due to mandibular deficiency. lateral cephalograms were analyzed at the beginning (t1, t 1) and end of the study (t2, t 2). results: paired t-test showed that snb had a significant increase in both groups. the same test revealed that impa was reduced in r-appliance for 3.1¡À4.7 (p<0.01), but it was increased for 0.1¡À5.1 (p<0.9) in aibp group. t-test showed that the inter-group difference of impa was statistically significant (p<0.05). sna showed an increase in both groups (p<0.9). ar-b and ar-pog showed an increase in both groups and the differences between them were statistically significant. conclusions: mandibular advancement was achieved in both groups, but r-appliance achieved this result without lingual tipping of lower incisors.
