Title:
PULP CAVITY DISTANCE MEASUREMENT SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2021/221406
Kind Code:
A1
Abstract:
A pulp cavity distance measurement system according to the present invention comprises: a first scan unit which acquires surface data; and a second scan unit which acquires volume data that is scan information different from the surface data, wherein the surface data and volume data are delivered via a database unit included in a control unit, and are merged into a single piece of data by a data merging unit. The shortest distance (pulp cavity distance) from the surface of the enamel of a tooth to the surface of the pulp cavity is calculated from the merged data, and the pulp cavity distance may be visually displayed by a distance stage display unit by using the calculated distance information (data). Here, the visual display may be expressed using colors or patterns having specific markings, and have a plurality of patterns so that the distance is displayed so as to be divided in stages. Accordingly, the system is advantageous in that a therapist can minimize tooth preparation in a part in which the distance to the pulp cavity is short, and reduce the discomfort of a patient due to vibrations caused by tooth preparation.
