Surgical Extrusion of a Fractured Lateral Incisor

This patient presented after trauma to the lateral incisor. The fracture extended around 3mm subgingivally on the palatal. The tooth was judged unrestorable on presentation. We discussed the options of extraction, orthodontic extrusion or surgical extrusion and the patient elected to proceed with the surgical option. This option carries some risk but has the benefit of being fast and less expensive. The tooth was root filled and then extracted and repositioned so that the palatal margin was supragingival. The tooth was temporarily bonded to the adjacent incisor to stabilise it while the repair of the socket occurred.

After 3-4 months of healing the PA indicates some surface resorption.

After a healing period. the tooth was restored by the patient’s dentist with a post and direct composite restoration. At two year review the resorption appears stable. There is normal periodontal probing. The tooth has a higher percussive tone indicating some ankylosis. We will continue to monitor the tooth for further resorption. At this stage there are no plans for a crown.
