Abstrakt: Objective: To evaluate the use of Class III Twin Blocks for the early treatment of Class III malocclusion. Design: Retrospective analysis. Subjects' and Method: 14 subjects were consecutively treated with a modified version of the Class III Twin Block appliance. Lateral cephalometric radiographs taken at the start and end of treatment were assessed digitally. Results: The mean age of subjects was 10 years and mean treatment time was 6.6 months. The cephalometric analysis of changes during treatment shows proclination of the upper incisors [mean 5.1°, SD 5.1], retroclination of the lower incisors [mean -4.5°, SD 3.9], reduction in angle SNB [mean -1.3°, SD 1.8] and an increase in the maxillary/mandibular planes angle (mean 2.1°, SD 2.2]. Average cephalometric digitizations and photographs of a clinical case are shown. Conclusions: Class III Twin Blocks can be used successfully for early treatment of Class III malocclusion. A randomly allocated prospective study is required to fully evaluate the efficacy of this appliance. [ABSTRACT FROM AUTHOR]
