The usefulness of three-dimensional imaging for prognostication in cases of intentional tooth replantation

Abstract

This paper describes the utility of three-dimensional (3D) images obtained with cone beam computed tomography (CBCT) for prediction of successful clinical outcome in two cases of intentional tooth replantation (IR). IR was performed for teeth affected by vertical root fracture and root perforation with local application of blood clot and oxy-tetracycline antibiotic. High-resolution 3D images demonstrated no evidence of ankylosis, but did reveal the presence of alveolar bone regeneration, suggesting a good long-term prognosis. Our observations in these cases suggested that local application of the above two materials might help to induce the regeneration of lost periodontal tissues in IR.
