| 内容記述 | Formation of Moiré patterns was described by Lord Rayleigh, who used it first for study of grating erregularities. Recently, the generation of surface contours by Moiré pattern techniques has been described. The generation of contour for three-dimensional objects by noncoherent methods is considerably interesting. Severe limitations and difficulties in the coherent methods are well known and will not be discussed here. Moiré topography, which is a new technique of the three-dimensional measurements by the utilizing Moiré fringe, is most welcomed by those who wish to study the shape of three-dimensional objects, because of the simplicity, high accuracy and real time advantage. The basic theory of the Moiré topography to the measuring and analysing three-dimensional objects in the field of prosthetic dentistry is described in this paper. Principle This arrangement has been suggested by Dykes (1970) and uses a point source of light located at the same distance from the Moiré grid as the camera or eyes. The Moiré fringe is formed by the grid and its distorted shadow on the objects. Generally, the depth of Moiré fringe at Nth is obtained as follows: h_N=bNp/(1-Np)where b is the distance of point source of light and eyes or camera from the grid surface, p is the pitch of the grating, and 1 is the distance between a point source of light and eyes or camera. Application to Prosthetic Dentistry Moiré topography has been utilized in an extend over a wide range, for example, medicine, dentistry, fashion industry, engineering and scientific criminal investigation. In prosthetic dentistry, this method has not been utilized in contour generation of three-dimensional objects. So we have interested in Moiré topography for the study of the contour of the patients faces before and after insertion of denture and the contour generation of the edentulous upper and lower casts. And also, this method is useful to observing the contour of natural teeth, and the change of the ridge form after extraction. And it remains that the orientating plane of the patients faces and/or casts which are generated the contour must be established. We are considering how to settle these problems. | |||||||
