A scanning photographing apparatus for evaluation of training with a transparent root canal tooth model

Abstract

A scanning photographing apparatus for evaluation of training with a transparent root canal tooth model is disclosed, the transparent root canal tooth model mounted on the tooth fixture is driven to continuously and uniformly run by a driving motor, and then the image of the peripheral side of the transparent root canal tooth model is scanned by the linear array camera assembly, image data of thelateral surface of the root canal of the dental model can be obtained for one week, An image of the root canal pulp chamber roof at the top of the transparent root canal tooth model was captured by aplanar array camera assembly, The image data of the pulp chamber of the root canal can be obtained, so that the shape data of the root canal in the whole tooth model needed for root canal treatment evaluation can be obtained completely through the two image data, which greatly reduces the workload and computational time of the subsequent software image analysis. Therefore, the apparatus can be used for daily objective evaluation of root canal treatment results in oral teaching, and is convenient to use, compact in appearance and generally affordable in economy.

Description

technical field [0001] The invention relates to the technical field of oral cavity teaching models, in particular to a scanning and photographing device for practical training and evaluation using a transparent root canal tooth model. Background technique [0002] Root canal treatment is one of the most common oral treatment procedures. For decayed teeth, root canal treatment is a must if you want to preserve the root of the tooth. Root canal treatment is performed after removal of carious dentin and pulp extraction. Root canal treatment usually includes root canal preparation (including root canal enlargement), root canal irrigation, and root canal filling. Each step has strict specifications and technical requirements. In oral teaching, teachers usually use natural isolated teeth or model teeth for students to practice. Teachers attach great importance to the teaching of root canal treatment. However, because the root canals of the simulated teeth are so small and the r...

Problems solved by technology

But so far, this kind of equipment has been positioned as scientific research equipment by the market, and the price is very expensive; the purchase and use of Micro-CT equipment requires relevant licenses; users need regular physical examinations, and users need certain protection during use; and CT The data obtained by scanning is very large, and a workstation-level computer is required to process the data. On the basis of the collected data, it is also necessary to outline and reconstruct the outline of the root canal wall, which is very time-consuming, and because of the material, the accuracy of the outlined outline is questionable. , these shortcomings are destined to be unrealistic for the daily objective evaluation of Micro-CT equipment used in root canal treatment training for middle school students
