Computer-assisted System to Generate a New Intelligent Rotary Dental Files IRDF Models

摘要

Natural systems studies inspire researchers to develop new algorithmic models to solve complex real-world problems to which traditional approaches. In dentistry the Root Canal Treatment (RCT) is one of the complex problems, where various types of file systems are used for canal cleaning and shaping purpose during RCT, as the canal anatomy is complex, it is difficult to operate with rotary instruments made from rigid material in curved canal geometry. Sometimes these files are blocked within the canal or broke due to development of higher stresses. Several approaches were performed to generate approximated Three Dimensional (3-D) models of files to import them to Computer Aided Design (CAD) software. This paper will present a new approach to build an accurate complex files models, starts with acquiring data by using computer tomography (CT) scanning and stereomicroscope in order to obtain files digital images. Then using the digital images obtained, the pitch of each file was determined to build of an intelligent 3-D model in form of sections. The algorithm using the taper of the files, the change in the file pitches length and the files cross section changes. Results will be imported to CAD software and compared with the previous and realistic models.
