Modified Serial Extraction in Patient with Sever Crowding: A Case Report

Serial extraction treatment is interceptive treatment to resolve arch length / tooth mass discrepancy. It follows serial extraction of primary teeth to facilitate the eruption of the 1st premolar and then extract it. In our case we present modification for the serial extraction treatmentby extraction of the 2nd premolars instead of the 1rs premolars. We believe that this is good modification to the serial extraction patterns, especially in cases with abnormal eruption sequence.
