Abstract

IntroductionThe aim of this study was to investigate the survival rate of teeth intentionally replanted with a modern technique and to compare their cost-effectiveness with that of single-tooth implants.Materials and MethodsFour databases were systematically searched for articles that met inclusion criteria published between January 1966 and February 2017. Overall survival rate of intentional replantation was determined through a meta-analysis using a random-effects model. Cost of different procedures was determined from the 2016 American Dental Association Dental Fees Survey. Cost-effectiveness analysis was performed for different treatment modalities.ResultsSix studies met the inclusion criteria. Meta-analysis resulted in a survival rate of 89.1% (95% confidence interval, 83.8%-94.4%). Compared with a single-tooth implant, intentional replantation was more cost-effective even when custom post/core and crown are also needed.ConclusionThe meta-analysis revealed a high survival rate for intentional replantation. Although the survival rate of implants is higher, intentional replantation is a more cost-effective treatment modality. Intentional replantation should be a treatment option discussed with patients, especially because an implant can still be placed if intentional replantation is unsuccessful.HIGHLIGHTSFirst systematic review on survival rate of teeth intentionally replanted with a modern technique and first cost-effectiveness analysis of intentionally replanted teeth.Survival rate of intentionally replanted teeth is 89.1%.Intentional replantation is more cost-effective than a single-tooth implant.When nonsurgical and surgical retreatments are not possible, intentional replantation is an alternative to extraction and replacement with a single-tooth implant.
