Teeth Bank - Autotransplantation of tooth-

Abstract

The patient was aged 38 years and 3 months old at the first visit. Although the upper left wisdom tooth had fully erupted, occlusion could not be achieved due to the extracted opposing tooth. Therefore, the wisdom tooth was extracted for use in the present study.
Dental X-ray was taken before extraction, and the donor tooth was polished. Xylocaine with 1:80,000 epinephrine was used as local anesthesia. Extraction was performed using only forceps with diamond particles. The extracted tooth was placed in a polypropylene container and immersed in preservative solution. The tooth in the solution was then frozen in a programmed freezer with a magnetic field. After the donor tooth had been frozen, it was preserved for 4 days in an ultracold freezer at -150°C. It was naturally defrosted at room temperature of 22°C directly before transplantation.
Root canal filling was performed with calcium hydroxide paste 30 days after transplantation. After autogenous transplantation of the frozen tooth, the periodontal membrane was regenerated, and the prognosis was satisfactory.
This article will discuss guidelines from the periodontal perspective to evaluate the treatability of  periodontally compromised adult orthodontic patients.
