Dental tissues involved in exarticulation, root resorption and factors influencing prognosis in relation to replanted teeth. A review.

Prognosis in relation to an exarticulated, replanted tooth is poor. Late complications are frequent and often lead to tooth loss. However, the root of a replanted, avulsed tooth may be slowly resorbed preserving alveolar width and postpones replacement of the tooth to a more convenient time. During healing following transplantation or replantation of teeth, various dental and oral structures are involved. Late complications relate to various factors. Tissues and factors involved are reviewed. Knowledge of this subject derives mostly from results of transplantation studies in animals.
