Abstract

INTRODUCTION:

The objective of this investigation was to examine the factors influencing the long-term prognosis of autotransplanted teeth with complete root formation.

METHODS:

Thirty-eight teeth, autotransplanted in 32 patients, were examined more than 6 years after transplantation. Periodontal health, condition of restoration, mobility, occlusal contact, level of gingival margin, and course of orthodontic movement were investigated clinically and with radiographs.

RESULTS:

More than 6 years after autotransplanation, 33 teeth survived in 27 patients. The survival rate was 86.8% (mean observation time, 9.2 years). Abnormal findings were observed in 9 teeth, so the success rate was 63.1%. An inadequate root filling tended to give rise to abnormal findings.

CONCLUSIONS:

The success of autotransplantation of a tooth with complete root formation is affected by the quality of root filling. When possible, clinicians should consider autotransplantation before root formation is complete.
