Cephalometric measurements and their impact on interlabial distance in individuals with and without anterior open bite: A comparative study

The interlabial gap in individuals with AOB is mainly influenced by vertical facial dimension, while in controls, maxillomandibular divergence and lip-to-S-line distances play a greater role. Moreover, AOB and increased vertical facial dimension are the most influential factors affecting the interlabial gap, highlighting the need to address both during orthodontic diagnosis and treatment planning.
