Leeway space is the size differential between the primary posterior teeth (C,D,E) and the permanent teeth (canine, first and second pre-molar). Maxillary space of 1.5mm, mandibular 2.5mm can be seen. Maxillary space of 1.5mm, mandibular 2.5mm can be seen.

Primary (baby) teeth start to form between the sixth and eighth week of prenatal development, and permanent teeth begin to form in the twentieth week. [1] If teeth do not start to develop at or near these times, they will not develop at all, resulting in hypodontia or anodontia .
The need for orthodontic space opening prior to prosthodontic management depends on the amount of edentulous space available in relation to adjacent teeth, occlusion and aesthetic concerns.
