What factor can assist in the alignment of teeth by providing leeway space?

Primate spaces are critical in orthodontics as they refer to the naturally occurring gaps between primary teeth, typically located between the maxillary lateral incisors and canines or the mandibular canines and first molars. These spaces provide essential leeway, allowing for proper alignment of permanent teeth as they erupt. The presence of primate spaces aids in accommodating larger permanent teeth in the dental arch, facilitating their proper alignment and reducing the likelihood of crowding.

Increased arch length does not directly contribute to the creation of space for teeth alignment; rather, it refers to the overall measurement of the dental arch. Ramus resorption deals with changes in the jawbone related to orthodontic movements or adult aging and does not play a direct role in creating space for tooth alignment. Broad face types may influence the overall facial aesthetic and perhaps tooth positioning, but they do not specifically create leeway space for tooth alignment like primate spaces do.
