Leeway space is due to ?
(A) Space differential between deciduous canine and molar and their succedaneous permanent teeth (B) Space differential between deciduous incisors and their succedaneous permanent teeth (C) Difference between deciduous and permanent maxillary and mandibular canines only (D) Difference between deciduous and permanent maxillary and mandibular molars only
(A) When the primary molars and canine are exfoliated the combined width of primary molars and canine are significantly larger than the premolars and permanent canine that replace them, and the “leeway space” provided by this difference offers an excellent opportunity of natural or orthodontic adjustment of occlusal relationships at the end of the dental transition
