The method of Root Canal Treatment before Extraction technique in an orthodontic extraction case with Labial Braces

Abstract

In the previous article on the method, we studied how to systematically close the extraction gap to resolve constricted alveolar bone malocclusion, which is common in orthodontics and may require several months or years to resolve. The main study pertains to orthodontic cases with a substantial arch-length discrepancy that require extractions; Class II Division 1 and 2 cases typically favor first bicuspid extractions. The study showed that root canal treatment of the indicated extraction bicuspids facilitates interproximal reduction of the mesial and distal areas, thereby providing space. This method provides an option to reduce the Arch Length Discrepancy and delay extraction timing during the initial alignment stage. The orthodontist's initial treatment aims to align the crowded area and correct the Curve of Spee. The treatment could begin with bracket placement, either Lingual or Labial orthodontic method, before reaching a stage at which it is ready to close the space created without extraction. This paper presents case studies to demonstrate the advantages and disadvantages of delaying extraction using the Root Canal First Before Extraction method. The sample cases are used to demonstrate the method's effectiveness and to highlight potential disadvantages in complex cases.
