Extraction vs nonextraction orthodontic treatment: a systematic review and meta-analysis
Conclusions:
Four first premolar extraction results in maxillary and mandibular
inter-first molar width decrease and retraction of upper/lower lips.
Nonextraction treatment results in mandibular intercanine width increase
and shorter treatment duration. There was no significant difference
between the two groups regarding maxillary intercanine width, US PAR
score, and posttreatment smile esthetics. Further high-quality focused
research is recommended.
