Abstract

Objective: The aim of this study was to investigate skeletal, dental and soft tissue

effects of Forsus Fatigue Resistant Device (FRD) and Jasper Jumper appliances in

correction of Class II malocclusion.

Methods: 33 patients were divided into two groups as treated with Forsus FRD

appliance (18 subjects: 8 females, 10 males-mean age: 15.79 ± 1.50 years) and

treated with Jasper Jumper appliance (15 subjects: 9 females, 6 males-mean age:

16.12 ± 1.58 years), randomly. Initial and final lateral cephalometric radiographies

were traced and analyzed digitally. The data were analyzed statistically.

Results: In the assessment of the skeletal parameters, both two groups had similar

outcomes and there were no statistically significant differences (p>0.05). In both

groups ANB, Convexity angles and Wits values decreased and maxillomandibular

discrepancy improved on sagittal plan. Maxillary incisors were proclined in Forsus

FRD group, and maxillary incisors were retroclined in Jasper Jumper treated group

and there was a statistically significant difference between groups (p<0.05). In the

assessment of mandibular incisor, proclination occurred in both two groups. In the soft

tissue evaluation, facial profile was improved through upper lip retrusion and lower lip

protrusion and there were no statistically significant differences between groups in

these values (p>0.05).

Conclusion: The skeletal and soft tissue effects of the Forsus FRD and Jasper

Jumper appliances were similar while there were some differences in dental effects.

Some factors such as skeletal age, cephalometric values should be taken into

consideration when making a choice about the fixed functional appliance.
