The Effect of Deciduous Cuspid Extraction on the IMPA Angle,
Abstract
The purpose of this paper was to determine the effect of deciduous cuspid extractions on the IMPA angle. Records were reviewed of 340 children receiving mixed dentition orthodontic care. Twenty-two (22) were found to have had no lingual arch placed after deciduous cuspid extraction. The analysis of the data revealed that no child lost IMPA if the initial FMIA was 65 degrees are greater before extractions. As the FMA increases over 28 degrees one can expect to lose IMPA after deciduous cuspid extraction. Of the 22 patients who had deciduous cuspids extracted, 10 patients lost IMPA and 12 patients had no change or an increase of IMPA. The findings strongly suggest that in patients with normal FMSs' and FMIAs' the extraction of the deciduous cuspids will not appreciably affect the IMPA.
