Syed Ameer Haider Jafri*

Primary dentition plays a vital role in developing speech, mastication, aesthetic, prevention of bad oral habits and eruption of permanent teeth [1,2]. Especially primary molars are very important in development of occlusion and guidance for the eruption of permanent molar. So whenever restoration in primary molar is not possible and extraction is the choice, there is always a risk of losing space resulting in malocclusion. Other adverse effects of pre-mature extraction of primary molar are mesial migration of first permanent molar, increased overbite, increased crowding, impaction, occlusal impairment, arch asymmetry and disruption of eruption sequence
