Pages 101-109, Language: EnglishWong, KevanThe extraction and reimplantation of teeth is a technique that has been practiced for many years, resulting in successful retention of teeth for up to 30 years. Although evidence confirming the advantages of this technique is limited, clinical observations and histologic examinations have revealed some important factors that are prerequisites for success: limitation of the time the tooth is exposed to the extraoral environment and preservation of vital periodontal tissue attachments on root surfaces. The latter goal can be achieved by gentle, atraumatic removal of the tooth from its socket, and hence the term exarticulation and reimplantation is more representative of the technique. In the present case report, a maxillary lateral incisor with a developmental defect was treated by exarticulation and reimplantation and application of calcium sulfate. Exarticulation and reimplantation seems to be a useful clinical procedure, but controlled studies are required to confirm its efficacy.
