Problems solved by technology

That is to say, regardless of the traditional impression or the current digital impression, the gingival retraction method such as the aforementioned gingival retraction line is required to perform gingival retraction, which will easily cause the patient's teeth to bleed, which will cause the patient's denture making process to be very uncomfortable and deep. Inconvenience and possible risk of tearing the patient's gingival ligament

Abstract

Provided are an optical tomography digital-impression imaging system and a method for use thereof, said system including: an optical coherence tomography scanner, used for obtaining tomographic slice thicknesses of a plurality of tissue areas of each optical tomography digital image; an information analysis and processing component electrically connected to the optical coherence tomography scanner. The information analysis and processing component has a refractive index compensation and optical path correction functions; by way of analysis and processing, tomographic slice thickness correction values corresponding to the tissue areas are obtained, thus establishing a digital model of the tissue areas.

Description

technical field [0001] The invention relates to an optical tomography digital impression image taking instrument and a using method thereof. It uses optical coherence tomography (OCT) technology to image the tooth structure, obtains the information of the tooth surface and the boundary structure of the teeth and gums under the gums, and performs tissue refractive index compensation to obtain the position of the teeth and gums in the actual space , and then establish a complete digital three-dimensional model of teeth through digital gingival retraction, and has a 3D file output function. Background technique [0002] The global fixed denture market continues to grow. To make a fixed denture, the patient's teeth must first be ground, followed by gingiva retraction to expose the ground teeth hidden in the gums, and then an impression is made. In the process, accuracy, dimensional stability, operating variables, etc. will directly affect the precision of the finished denture. ...
