The 3D scanner for dental use, which is a 3D scanner for acquiring 3D data of an intraoral structure, comprises: a mode selecting unit which generates a mode selection signal for selecting a resolution of the 3D data; a light source unit which generates a measurement light; a photographing ...
PROBLEM TO BE SOLVED: To provide a three-dimensional color/shape-detecting apparatus for accurately measuring a color and a three-dimensional shape over the entire object to be measured. SOLUTION: The three-dimensional color/shape-detecting apparatus 1 comprises a measurement head 10 having a laser...
A three-dimensional evaluation of a laser scanner and a touch-probe scanner Statement of problem The fit of a dental restoration depends on quality throughout the entire manufacturing process. There is difficulty in assessing the s... OG Sandborgh-Englund - 《Journal of Prosthetic Dentistry》 被...
The dental calculus and periodontal tissue were removed following informed consent from the patient. The 3Shape intraoral scanner was used to obtain 3D images. The STL data was exported and GEOMAGIC 2017 software was then used to process the polygonization and surface smoothing, resulting in a ...
similar number of polygons. The dental region, including erupted teeth and alveolar bone, was manually selected on the 3D model and leveled (flattened) using theerase and fillfunction in Meshmixer (Fig.2). This was done to minimize the impact of the dental region on the statistical shape ...
The aim of this study was to propose a method for assessing the degree of mandibular anterior dental crowding in the three planes of space, using digital dental models. Thirty dental casts were selected and scanned by Maestro 3D Dental Scanner and imported by Geomagic Qualify 2013 software. The...
Technical comparison of the scanning/scanner systems The working distance of the Artec Eva is the smallest (0.2–0.3 m). The acquisition time and the processing time of the 3dMD are the smallest, 1.5 ms and immediate, respectively. The manufacturer reported that the Artec Space Spider (0.1 mm...
The variation results from the irregular shape of dental and skeletal structures and individual variations in thickness and tension of soft tissues. Orthodontic treatment directly changes the position of hard tissues such as teeth or bones, and subsequently affects the facial appearance which is ...
(CoCr) remain unclear and worth exploring. A patient’s intraoral data were obtained via CBCT and master model scan. Four RPDs were designed by 3Shape dental system, and the models were processed by three-dimensional finite element analysis. Among three materials tested, PEEK has the lowest ...
This limitation is because existing dental software programs have mainly used volume-rendering techniques to express both soft and hard tissues12. This technique defines the color and transparency of all voxels of a 3D face and then projects it in 2D to express the detailed 3D shape of the ...
