Abstract
Purpose: The purpose of this study was to assess the dentoskeletal effects of R-appliance in treatment of patients with Class II division1 in the late mixed dentition stage.
Methods and Material: The sample included twelve cases (6 females and 6 males), with average age of 10.5 years, who were treated by R-appliance for 12 months. All cases had malocclusion Class II division 1 due to mandibular retrusion. Lateral cephalograms were taken and analyzed before and after the treatment to evaluate the efficacy of the appliance.
Result: statistical analysis using the SPSS version 20.0 revealed that there was highly significant increase in SNB angle by 4.14 mm (P<0.001). The highly significant increase in mandibular length was 1.8 mm, (P= 0.003). Also, the wits appraisal was found to be significantly decreased by (p= 0.001*). The vertical measurements showed significant difference with (S- GO, N – Me, Ans –Me) by (p= <0.001*). The dentoalveolar measurements were significantly decreased with overjet around 5.42mm (P <0.001*) and statically significant with (U1-L1, U1 – SN) recorded (<0.001*) for both.
Conclusion: The study concluded that the treatment of Class II malocclusion due to mandibular deficiency by R-appliance was effective.
