ABSTRACT:Early loss of primary teeth lead to loss in space, arch length, arch perimeter and arch circumference. The normal occlusal relationship and normal permanent teeth alignment is not able to develop and permanent teeth remain impacted or erupt out of arch. When the space is progressively lost, the therapy should be considered to regain the space so that additional disharmonies do not develop. Space regainers are the appliances used to restore space and occlusal harmony and further minimize the complex orthodontic treatments and facilitate permanent tooth eruption. This article is an overview which depicts a range of space regaining appliances, removable and fixed, used to overcome or reduce space discrepancies.
