Reimplantation

The reimplantation (of lat .: re - again, back and implantare - plant ) is a treatment procedure in dentistry , in which a by trauma from his tooth socket dislocated tooth back into its socket is reset. As a rule, the tooth is splinted after reimplantation. Front teeth are mainly affected.

requirements

The bloody remnants of the periodontal membrane and the fibers of the tooth support system are clearly visible. However, this tooth was extracted because the entire crown had rotted away.

After a tooth has been avulsion , treat it as gently as possible and keep it moist. A tooth rescue box was developed for this purpose , in which the tooth can be stored in a nutrient solution. If this is not available, the tooth can be stored in milk or, if necessary, in the mouth. If possible, the tooth should be re-implanted in less than an hour. The success rate drops significantly over a longer period of time.

The prerequisite for a successful reimplantation is the preservation of the major part of the alveolus (tooth socket) and the preservation of the root skin of the tooth.

Action

3D adhesive ring

To reduce germs, the tooth is briefly placed in a doxycycline solution and then repositioned in its tooth socket. The tooth is then fixed using a titanium composite splint for eight to ten days.

The tooth is devitalized by the avulsion, as the nerve and blood vessel connections have been permanently interrupted. As a result, the tooth must undergo root canal treatment. This takes place about eight to ten days after the reimplantation. The previously practiced procedure of endodontically treating the tooth extraorally (outside the mouth) in the reimplantation treatment session was abandoned because it unnecessarily extended the period of time during which the tooth was not again in its socket and, on the other hand, the sensitive periodontal membrane (Periodontal) could easily be damaged. The preservation of the periodontal bone is a prerequisite for the tooth root not being resorbed.

history

In the past, a tooth that could not be root canal treated in the normal way was extracted , root canal treated outside the oral cavity and then repositioned or fixed in the jaw with a pin extending beyond the root tip (transfixation). Due to the advances in endodontics and possible surgical techniques for apical resection , the procedure is no longer indicated. This also applies to transdental fixation (resection + root-lengthening pin)
