ABSTRACT

Objectives:The purpose of this clinical prospective study was to compare the dentofacial changes produced by the Sabbagh Universal Spring (SUS²) and Forsus FRD appliances in late adolescent patients with Class II malocclusion, and quantify them in comparison with an untreated group.

Methods: The study was carried out on 59 patients with skeletal and dental Class II malocclusion due to retrognatic mandible. Among these, 20 were treated with SUS², 20 were treated with FRD, and no treatment was done to 19 subjects as the control group. 36 cephalometric landmarks were identified on each lateral cephalometric radiograph.

Results:The effects of both appliances were dentoalveolar and no significant vertical and sagittal skeletal effect on maxilla and mandible was achieved. The retrusion and extrusion of the maxillary incisors as well as the protrusion and intrusion of mandibular incisors were found to be statistically significant in both treatment groups. Soft tissue profile improvement was limited in both treatment groups.

Conclusions: Both appliances corrected Class II discrepancies through dentoalveolar changes; however lower incisor proclination was more prominent with the Forsus FRD. (Eur J Dent 2012;6:302- 310)
