Micro-fracture measurement device and micro-fracture measurement method using the same

摘要

A tooth specimen including a base substrate and an adhesive resin adhered thereto, a sensor attached to the tooth specimen to detect an acoustic emission signal of the dental specimen according to an external force, and a measurement unit for measuring the acoustic emission signal sensed by the sensor and to detect the initial fracture point of the adhesive resin with the measured acoustic emission signal, and provide an apparatus for measuring fine fractures and a method for measuring fine fractures using the same, characterized in that the physical properties of the adhesive resin are evaluated.
