Clinical outcomes after intentional replantation of permanent teeth: A systematic review

Abstract

This study aimed to systematically assess the outcomes of intentional replantation (IR) of teeth and to determine the survival rate, success rate, and prognostic factors related to the treatment. A search was conducted for all relevant English language articles published from January 2000 to October 2017. The search terms included "intentional replantation" and "teeth" according to the inclusion criteria. The Methodological Index for Non-randomized Studies (MINORS) was used to assess the methodological quality of included studies. Twelve studies were identified as relevant for the systematic review. In total, 896 patients with 905 teeth were examined for intentional teeth replantation. The success rate was greater than 90% in four studies (33.33%) and between 70% and 80% in five studies. At short-term follow-up (<6 months), the survival rate was approximately 90%. At longer-term follow-up (>36 months), the survival rates of teeth were slightly reduced in four studies, and tended to be stable after 48 months. In conclusion, the long-term success and survival rate of IR are likely dependent upon short extraoral time, reduced pocket depth, type of tooth, type of root-end filling material, and the prevention of atraumatic tooth root damage.

In the dental implant era, why do we still bother saving teeth?

“…The teeth are not mobile, and there are no periodontal pockets or active disease success rates in the first 6 months. 43 Between 6 and 12 months, the survival rate decreased from 85% to 80%, and after 48 months, the survival rate of replanted teeth stabilized. [43][44][45] A meta-analysis of 6 studies also showed a high success rate of 89.1% of intentionally replanted teeth.…”

[43][44][45] A meta-analysis of 6 studies also showed a high success rate of 89.1% of intentionally replanted teeth. 46 The success of this procedure is influenced by several factors including the extent of periodontal disease and the presence of root fracture.…”

“…Intentional replantation involves purposefully extracting a compromised tooth and replanting the tooth into its socket. [43][44][45] A meta-analysis of 6 studies also showed a high success rate of 89.1% of intentionally replanted teeth. The teeth are not mobile, and there are no periodontal pockets or active disease success rates in the first 6 months.…”

“…43 Although intentional replantation is considered as a last resort treatment option, the treatment was reported to have a 90% F I G U R E 1 A patient with stabilized periodontal condition on a significantly reduced periodontium under supportive periodontal therapy.
