Conditions

Tooth extraction due to extensive tooth decay Oral Health

Interventions

Patients assigned to the procedure will have a maxillary cone-beam CT radiographic examination. The third molar or tooth to be transplanted with the imaging volume will be modelled to create a 3D-prin

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: 1. Patients under the age of 25 years 2. One or more missing teeth or irreversible dental damage 3. Seeking help at the RSU Institute of Stomatology for the restoration of dental row defects 4. Have indications for autotransplantation of third molars 5. Understand the nature of the procedure and give informed consent 6. The third molars have not erupted 7. Clinically healthy 8. Good oral hygiene 9. Non-smokers

Exclusion criteria

Exclusion criteria: 1. Unsuccessful extraction of the donor's tooth 2. Insufficiently formed roots of third molars 3. Patients with chronic diseases 4. Pregnancy 5. The patient does not attend control visits

Design outcomes

Primary

Measure	Time frame
Survival of the auto-transplanted tooth measured in months or years	—

Secondary

Measure	Time frame
1. Surgical time used, measured in minutes from the first incision to the end of the last suture 2. Donor extra alveolar socket time(s), measured in minutes. The extracted tooth was fitted into the recipient’s socket in the control group. For extra-alveolar time in the control group, only the time that it was outside the original socket was registered. 3. Donor fitting times, measured in minutes. Fitting into the recipient socket attempts was recorded. If the socket had to be adjusted, then extracted donor's tooth was gently replaced back in the original socket. 4. Success and survival rate at 1, 3, 6, 12 and 24 months after autotransplantation. Survival will be considered as the permanence of the auto-transplanted tooth, in the absence of infection or pain and with radiographic evidence of the absence of adjacent bone problems. 5. Infection/alveolitis rate, defined as the proportion of sites that had a clinical diagnosis of alveolitis after the surgery or required antibiotic therapy at any moment after the surgery 6. Any other adverse effects reported in addition to infection, swelling or pain at 6, 12 and 24 months	—
