The models were visualized using numerical data-visualization software (Micro-AVS ver.8.1, KGT), and display conditions were evaluated, resulting in the following conclusions: 1. Regarding the database of 3-dimensional models, voxel model type data were considered appropriate. 2. Three-dimensional images, which can be used to observe the internal structure, are useful for learning dental students. 3. Simulated treatment becomes possible using the haptick device and 3-dimensional data. This modality was considered very useful clinical practice for students. 4. When data for the finite element method are produced based on these data, various analyses become possible, and researchers can also effectively use these data. 5. If human tooth 3-dimensional data become widely available, various types of usage will be possible; therefore, accumulation of further data on carious, abnormal, and deciduous teeth is necessary to expand the data set.}, pages = {1--7}, title = {人歯3次元モデルの作成 : ボクセルモデル}, volume = {35}, year = {2009} }
