Immediate Tooth Replantation

Replantation is a procedure in which the teeth that have been completely removed from the alveolar fossa are treated and then returned to the original alveolar fossa. It is suitable for full dislocation of the teeth due to trauma, or artificially removed the diseased teeth for treatment and replantation. The latter is a means of treating periodontal disease and is also used for surgical orthodontic treatment of individual torsion teeth. Replantation of teeth is replanted and delayed replanted. Treatment of diseases: tooth folding Indication Immediate tooth replanting is suitable for dislocation of one or more anterior teeth due to a fall or violent impact. 1. Dislocated teeth that have been removed from the body should be considered for immediate replantation at the site or with a dental visit; if dislocated, soft tissue attachment is also an indication for replantation. 2, replantation of dislocated teeth after injury, the best effect of a single tooth; two dislocation teeth can also be considered replantation; more than two are often accompanied by a wide range of alveolar bone fractures, should not be replanted. 3, the younger the age, the better the replanting effect, especially in the root canal has not been developed should be given priority. 4, the injured and dislocated teeth should be intact, if there is a serious disease, it should not be replanted. 5, the position of the reversal of the reversal of the tooth, limited to a single healthy anterior teeth of adolescents under the age of 20. Contraindications 1. The teeth have not been properly preserved for more than 24 hours, and the periodontal ligament is dry and polluted. 2. Multiple dislocations of the teeth, accompanied by comminuted fractures of the alveolar bone and soft tissue defects. 3, the age is too large, alveolar bone has more than 2 degrees of horizontal or longitudinal absorption, accompanied by other missing teeth. 4. The fracture of the dislocated teeth is severely broken or has a root fold. 5. The torsion tooth is in a crowded, overlapping position and has a bent root. Preoperative preparation Replant preparation was completed within 30 minutes. 1. The dislocated teeth were immediately washed with physiological saline and immersed in antibiotic saline. 2, after local anesthesia under sterile conditions, alveolar fossa cleaning, removal of blood clots, alveolar bone manipulation reset. 3, before the re-planting of the torsion, X-ray examination should be performed to understand the condition of the root and periodontal membrane. 4. Prepare the fixtures and instruments after replanting and disinfect them for use. Surgical procedure 1, the treatment of dislocated teeth Dislocation teeth with soft tissue adhesion, do not remove or damage soft tissue during disinfection; after removing the dislocated teeth from the antibiotic saline, carefully remove the foreign matter and rinse it repeatedly with antibiotic liquid; care should be taken to protect the root surface when cleaning the dislocated teeth. Periodontal membrane. Teeth that have not yet completed the development of the apex, routinely do not remove the pulp. A tooth with a developed apex, a view that the pulp should be removed and the root canal is replanted; another view is that the pulp is not treated first, and the dental pulp is stabilized, such as when the pulp changes. Root canal treatment. The torsion of the tooth is immediately replanted, regardless of the tooth or pulp. 2. Treatment by planting area Debridement under local anesthesia after routine disinfection. The torn gingiva and the displaced alveolar bone should be firstly reset, the finger pressure is used to reduce the alveolar fossa, and the implant is closely fitted after the implant is inserted, and the old blood clot or foreign body in the alveolar fossa is removed, and the antibiotic saline is repeatedly washed. 3, implant teeth Lightly scrape the socket to fill it with blood and refill the treated dislocated teeth into the socket. When the tooth neck and the gum are not close together, the gingival nipple can be sutured intermittently; when the tooth root is inconsistent with the bone wall after the tooth is rotated, the bone wall can be enlarged or cut off by the small bone chisel. 4, fixed After replantation of a single tooth, the adjacent teeth can be used to make the interdental wire; after more than 2 teeth are replanted, the plate is fixed with a local or single jaw arch. Preventing bite wounds or excessive bearing capacity is the key to successful replanting. complication 1, periodontitis, deep blind pocket, bone resorption, tooth loss. 2. Re-implantation of root surface absorption and intramedullary absorption.
