An Exploratory In Vitro Microcomputed Tomographic Investigation of the Efficacy of Semicircular Apicoectomy Performed with Trephine Bur

Applied Sciences, 2023
Purpose: Recently, a novel approach to apicoectomy has emerged, involving the use of a hollow trephine with a surgical guide. This innovative technique creates a semicircular section, in contrast to the conventional straight cut (with a bur).
