Efficient digitalization method for dental restorations using micro-CT data
The objective of this study was to demonstrate the feasibility of using micro-CT scan of dental impressions for fabricating dental restorations and to compare the dimensional accuracy of dental models generated from various methods. The key idea of the proposed protocol is that dental impression of patients can be accurately digitized by micro-CT scan and that one can make digital cast model fr...
متن کاملEvaluation of internal adaptation of dental adhesive restorations using micro-CT
Department of Conservative Dentistry, Yonsei University School of Dentistry and Oral Science Research Center, Seoul, Korea Objectives: The internal adaptation of composite restorations with or without resin modified glass ionomer cement (RMGIC) was analyzed non-destructively using Microcomputed tomography (micro-CT). Materials and Methods: Thirty intact human teeth were used. The specimens were...
متن کاملEfficient 3D finite element analysis of dental restorative procedures using micro-CT data.
OBJECTIVES This investigation describes a rapid method for the generation of finite element models of dental structures and restorations. METHODS An intact mandibular molar was digitized with a micro-CT scanner. Surface contours of enamel and dentin were fitted following tooth segmentation based on pixel density using an interactive medical image control system. Stereolithography (STL) files ...
متن کاملAn Efficient Ring Artifact Reduction Method Based on Projection Data for Micro-CT Images
Ring artifacts are very troublesome in a flat-panel based micro computed tomography (micro-CT) since they might severely degrade visibility of the micro-CT images. Unlike ring artifacts in other types of micro-CTs such as image-intensifier based micro-CT, ring artifacts in a flat-panel detector based micro-CT are hardly removable since the sensitivity of the pixel elements in a flat-panel detec...
متن کاملAn Efficient Functional Analysis Method for Micro-array Data Using Gene Ontology
Microarray data includes tens of thousands of gene expressions simultaneously, so it can be effectively used in identifying the phenotypes of diseases. However, the retrieval of functional information from a large corpus of gene expression data is still a time-consuming task. In this paper, we propose an efficient method for identifying functional categories of differentially expressed genes fr...
