Primate spaces are diastemata consistent with an inherent physiological pattern rather than functional adaptation. This article presents an atypically increased primate space only in the right mandibular arch.
Primate spaces, those between the primary lateral incisor and canine in the maxilla and the primary mandibular canine and first molar in the mandible, are anthropometric diastemata that are consistent with an inherent physiological pattern rather than the result of functional adaptation.1 Approximately 60% of children have primate spaces in their primary dentition.2 Primate spaces are more commonly present in boys than girls and are often noted in the maxillary arch (83.7%) compared with the mandibular arch (61.2%).3
Although there is considerable variation in the presence or absence of primate spaces, they tend to remain stable following the eruption of the primary teeth, with little evidence of primary canine relationship changes in either arch.3 Primate spaces tend to occur more frequently and with wider mesio-distal dimensions in the maxilla compared with the mandible.4
