(TC67) Orthodontic Forced Eruption: An Alternative Treatment Modality for Teeth With Compromised Coronal Tooth Structure

This table clinic presents a unique case report of a forced eruption of a maxillary lateral incisor. A 27-year-old female presented with tooth #10 without its crown or any coronal tooth structure supra-gingivally due to trauma. It was previously treated with RCT and a fiber post 5 years prior. Dental examination revealed no percussion or palpation sensitivity, and periodontal probing's circumferentially were 3mm or less. With patient consent, forced eruption was planned after endodontic re-treatment and placement of a new metal post and core, to be followed by a new crown. A composite button was bonded on to the buccal of #10, and an Essex retainer made with a notch on the lingual surface. Elastic was placed around this buccal button and over the Essex appliance into the lingual notch, and was worn daily, with the elastic being replaced every other day by the patient for 2 weeks. A fiberotomy procedure was performed both at day two and at one-month post-treatment initiation. Tooth #10 was sufficiently extruded after two weeks of extrusion with the appliance and was stabilized with a splint using braided ligature wires for six weeks. After this, the tooth was prepared for a new crown and was seated 10 weeks post extrusion. A six-month recall evaluation revealed complete healing of #10 without any concerns from the patient. This case report demonstrates orthodontic extrusion as a valuable but underutilized treatment option in the management of teeth with compromised coronal tooth structure.
