Developmental tooth transplantation

Developmental tooth transplantation is the operation of transplanting the patient's own buried teeth, impacted teeth, and dislocated teeth from one location to another.

Developmental tooth transplantation is suitable for:

1. At present, the most commonly used is to transplant the mandibular third molars whose roots are not completely formed or fully formed into the alveolar socket of the first eruption but caries of the mandibular first molars to heal and grow instead of the first molar Functions.

2. According to the needs of correction, transplant the undeveloped premolars of the extracted roots to the corresponding side or the corresponding lacking area.

3. Impacted teeth or misplaced anterior teeth that have not been developed or have been developed are transplanted to the normal occlusal site.

1. Patients with severe alveolar bone resorption and obvious inflammation in the first molar region.

2. When the third molar is removed, it is expected that the operation will be difficult, and severe injuries such as coronary fissure or root canal will be expected.

3. When the 3rd molar with incompletely formed apex is pulled out, the apical nipple is severely damaged.

4. The bone gap in the recipient area is too small to accommodate the graft.

5. There is severe periodontitis in the adjacent teeth of the affected area, and the loosening is more than degree.

6. For those with long teeth and low gingival space.

1. X-ray examination of the affected area to observe the alveolar bone resorption and the periodontal condition of adjacent teeth.

2. To observe the apical development of donor teeth and its relationship with adjacent teeth and mandibular canals.

3. Ring metal splints for pre-grafted teeth.

Inferior alveolar nerve, buccal nerve and lingual nerve block anesthesia plus local soft tissue infiltration anesthesia.

The patient assumes a supine or sitting position.

The method of transplanting the developed teeth is basically the same as that of tooth germ transplantation. The difference is:

Immediately after the extraction of the donor tooth, the stones in the crown and neck are scraped off, washed with soap water and a brush, and then soaked in physiological saline containing antibiotics, treated as soon as possible within 30 minutes after leaving the body, and placed in the prepared Alveolar fossa.

When the affected area is not suitable for immediate transplantation, treat the teeth immediately after they are removed from the body and store them in a low-temperature refrigerator within 30 minutes. The transplantation can be performed after 7-10 days. After re-warming the transplanted teeth from the refrigerator, flush them with normal saline and fix them after implantation. There should be no early contact in the middle.

1. There was no serious infection or pus fistula in the alveolar socket of the affected area.

2. No root fracture and no damage to the apex.

3. There is no contact with the maxillary teeth in the median position after implantation.

4. The fixing is really reliable.

After the development of the tooth transplantation, a monthly or bi-monthly follow-up visit will be performed for clinical examinations, including the depth of the blind bag, looseness, and X-ray pictures.

Autograft teeth can generally function for 5 to 10 years. More than 18 years of age more than root absorption.
