NONDESTRUCTIVE EXAMINATION METHOD OF FALSE TOOTH BY USING OPTICAL COHERENCE TOMOGRAPHY (OCT)

摘要

PROBLEM TO BE SOLVED: To solve such problems that a conventional nondestructive examination of false teeth is proposed by using X-rays or ultrasound and does not make an accurate evaluation and that images of surfaces and internal parts of the false tooth are not obtained especially in an non-invasive and simultaneous manner since the secular variations of the false tooth on which repair or lining are performed are determined by the status inside the oral cavity of a wearer or doctor's questions/a visual inspection and are not evaluated by objective evaluation methods. SOLUTION: This invention provides an apparatus for making an evaluation inexpensively and instantly by using OCT or optical coherence tomography and the method for obtaining damage of the internal part of the false tooth by an image in order to contribute to dental treatments and for evaluating by capturing three-dimensional images of the false tooth by using the method when manufacturing the false tooth or at a place of adjusting to fix the false tooth.
