INTRODUCTION: Agenesis of a maxillary lateral incisor occurs in about 2% of the
population. Treatment options should adapt to natural biologic changes in a
lifelong perspective.
METHODS AND RESULTS: A young woman with bilateral agenesis of the maxillary
lateral incisors was treated with transplantation of a developing maxillary
third molar on one side and a dental implant on the contralateral side, after
orthodontic space opening. The periodontal examination, including bacterial
testing of the transplant, the implant, and the control central incisor, was
performed 9 years after the treatment. A radiologic assessment was also
performed. The transplanted tooth did not differ from a natural incisor, except
for the pulp obliteration, and the total bacteria count was higher at the
implant site. The periodontal tissues around the implant showed progressive
signs of recession.
CONCLUSIONS: Both tooth transplants and dental implants for replacing missing
maxillary incisors can be effective in the long term. This report supports
natural tooth substitution rather than implant placement for dental agenesis in
the anterior maxilla.
