Two Severely Compromised Teeth Restored Using Digital Planning Combined With Double Orthodontic Magnetic Extrusion: A Case Report

Tooth tissue loss due to dental caries is frequently challenging to restore, and this loss is made worse by proximal tooth borders that extend below the gingival margin. This report describes a digitally designed case in which the ferrule and supracrestal tissue attachment were preserved by simultaneous double magnetic extrusion of two root filled teeth. A 67-year-old male presented with the chief concern of a fractured maxillary left canine. The maxillary left lateral incisor and canine underwent rapid magnetic extrusion to create ferrules (3 mm). Eighteen months after treatment, the restorative margins were sound and the teeth with associated periodontal tissues were healthy. The positive results demonstrate that the combination of digital planning and double magnetic extrusion has potential as a technique for restoring severely damaged teeth where insufficient supra-gingival tooth tissue remains. Adjacent root canal treated teeth with severe loss of coronal structure are suitable candidates for double magnetic extrusion.
