This study aimed to quantitatively evaluate the relationships between the horizontal or vertical balance of the LCF<\/jats:styled-content> generated during maximum voluntary pursing\u2010like movements and dental arch length (DAL<\/jats:styled-content>) or width (DAW<\/jats:styled-content>) or the lingual inclination of the upper or lower 1st molars (LIUM<\/jats:styled-content>, LILM<\/jats:styled-content>) in patients with Angle Class I malocclusion. Sixteen subjects with Angle Class I malocclusion (median age: 23\u00b74 \u00b1 5\u00b79 years) who had never undergone orthodontic treatment were randomly selected. LCF<\/jats:styled-content> was measured in eight directions during maximum voluntary pursing\u2010like lip\u2010closing movements. Dental arch models were scanned and analysed to obtain DAW<\/jats:styled-content>, DAL<\/jats:styled-content>, LIUM<\/jats:styled-content> and LILM<\/jats:styled-content> measurements. Mandibular deviation was measured on posteroanterior cephalograms. A significant negative correlation was detected between maxillary DAL<\/jats:styled-content> and upper LCF<\/jats:styled-content>. Maxillary DAL<\/jats:styled-content>, DAW<\/jats:styled-content> and the DAL<\/jats:styled-content>\/DAW<\/jats:styled-content> ratio displayed significant negative correlations with total LCF<\/jats:styled-content> and upper LCF<\/jats:styled-content>. However, no significant correlations were detected between any mandibular dental arch morphological parameter and LCF<\/jats:styled-content>. The difference in the LIUM<\/jats:styled-content> between the deviation and non\u2010deviation sides exhibited a significant positive correlation with the difference in upper LCF<\/jats:styled-content> between the deviation and non\u2010deviation sides and was significantly negatively correlated with the difference in lower LCF<\/jats:styled-content> between the deviation and non\u2010deviation sides. These results suggest that upper LCF<\/jats:styled-content> is related to maxillary DAL<\/jats:styled-content>, and the horizontal balance of the LCF<\/jats:styled-content> of the upper and lower lips is related to the LIUM<\/jats:styled-content> during pursing\u2010like lip\u2010closing movements in patients with Angle Class I
