Autotransplantation is the transplantation of one's own tooth, unimportant for the bite and chewing process ("eight" or wisdom tooth), instead of a destroyed tooth that cannot be restored. In this clinical situation, tooth 46 is severely damaged. Treatment protocol: 1. Removed 46 tooth. 2. Cleaned the hole. 3. Removed tooth 38 and transplanted instead of 46 tooth. 4. Splinted on the adjacent tooth. Next stage: ✅After 2 weeks we remove the nerve and put Ca + for 2 weeks. ✅After 2 weeks we carry out obturation. We put a crown on this tooth and complete the treatment. ✳️ Another thing to consider is TIME. You will need to have time to transplant the extracted tooth within 18 minutes.
