Immobilization of root-compromised maxillary anterior teeth: a case report with 14-year clinical follow-up.

The efficacy of a modified cast-metal resin-bonded splint was evaluated after 14 years in service. The splint was used to immobilize the root-compromised maxillary central and lateral incisors of a teenage male following relapsed orthodontic treatment. The affected teeth were indirectly traumatized, before their eruption, in a bicycle accident that resulted in avulsion of their primary predecessors. The rationale for selecting this treatment modality rather than the alternatives is discussed. The clinical protocol employed during the treatment and subsequent follow-up is described.
