- Objectives
While the success criteria of endodontic microsurgery (EMS) have been consistently defined and widely accepted, the success criteria of dental implants are outdated and focus only on the implant fixture and surrounding bone. This study aimed to evaluate the outcomes of EMS and single implants (SIs) with explicit criteria.
Methods
We searched for articles published from January 2010 to February 2022 and discussed them and consulted with a clinical advisory committee composed of four dental specialists and one epidemiologist during article selection and data extraction.
Results
Twenty-two EMS studies and six SI studies were included in the meta-analysis. Teeth treated using EMS had a pooled success rate of 89% (90% at <5-year follow-up and 80% at ≥5-year follow-up) and the pooled success rate of SI was 78%.
Conclusions
The success rates of the two procedures with similar follow-up periods were comparable. Subgroup analysis found no other variable that significantly influenced study heterogeneity. Considering the treatment sequence and the similar success rates, it would be advantageous to consider EMS, rather than implants, first in a situation where both procedures are applicable.

Apical surgery cuts off the apical root and the crown-to-root ratio becomes unfavorable. Crown-to-root ratio has been applied to periodontally compromised teeth. Apical root resection is a different matter from periodontal bone loss. The purpose of this paper is to review the validity of crown-to-root ratio in the apically resected teeth. Most roots have conical shape and the root surface area of coronal part is wider than apical part of the same length. Therefore loss of alveolar bone support from apical resection is much less than its linear length.The maximum stress from mastication concentrates on the cervical area and the minimum stress was found on the apical 1/3 area. Therefore apical root resection is not so harmful as periodontal bone loss. Osteotomy for apical resection reduces longitudinal width of the buccal bone and increases the risk of endo-perio communication which leads to failure. Endodontic microsurgery is able to realize 0 degree or shallow bevel and precise length of root resection, and minimize the longitudinal width of osteotomy. The crown-to-root ratio is not valid in evaluating the prosthodontic prognosis of the apically resected teeth. Accurate execution of endodontic microsurgery to preserve the buccal bone is essential to avoid endo-perio communication. -
