Abstract

Introduction

The 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 Methods

Four 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.

Results

Six 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.

Conclusion

The 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.
