Problems solved by technology

Therefore, the CCD sensor is only fixed on the photoreceptor mounting plate, and its lower end is fixed with a protrusion structure or fixed with a rubber band, so it is difficult to accurately locate the position suitable for the CCD sensor to shoot.
In addition, if different kinds of sensors are used selective

Embodiment Construction

[0044] The preferred embodiment of the present invention will be described below with reference to accompanying drawings 1-12.

[0045] figure 1 The right molars on the palate and the left molars on the mandible are taken as the shooting objects, and the isometric front view of the right molars on the palate is photographed using the imaging tool with a special sensor bracket for fixed dental X-ray imaging CCD sensors provided by the present invention . figure 2 It is a perspective view of the arrangement relationship of each part when the main body of the imaging tool is assembled. image 3 It is a perspective view of the sensor holder installed on the main body of the imaging tool. as well as Figure 4 It is a perspective view of the assembled state of the imaging tool. This kind of imaging tool 1 with a special sensor bracket for fixing the dental X-ray imaging CCD sensor has a support frame 2 that constitutes the core of the tool. The front side of the tool is narrow...

Abstract

Disclosed is a photography tool which can use various image capturing CCD sensors having different external shapes, facilitates creation of an image exhibiting excellent reproducibility by positioning various sensors accurately, suppresses strangeness by stabilizing the occlusion state in the oral cavity, and ensures good holding state. In a photography tool (1) with an exclusive sensor holder for mounting a CCD sensor for capturing a dental X-ray image, a sensor mounting portion corresponding to the external shape of a sensor (16) is formed by inclining the sensor supporting substrate (18) of a sensor holder (17) at a predetermined angle and projecting curved portions (19, 20) from the upper and lower ends of the supporting substrate (18), a fitting protrusion (25) is provided on the supporting substrate (18), a fitting groove (12) to which the fitting protrusion (25) is fitted and which has the identical cross-sectional shape is provided in the main block (9) for occlusion, the shape of the sensor mounting portion is changed every time when the external shape of the sensor (16) is different, various holders (17); are made by changing the vertical position of the sensor mounting portion every time when the image capturing position for a tooth (28) to be inspected is different, and each holder (17) is provided with the fitting protrusion (25) of the identical shape.

Description

[0001] technical field [0002] The invention relates to a photographing tool for installing a CCD sensor used when taking dental X-ray films in dental treatment. Background technique [0003] Conventionally, when taking an X-ray film for dental treatment, an X-ray film is fixed on the inner side of the tooth to be examined, and the projection direction of the X-ray tube is determined based on the X-ray film, and then the photograph is taken. Therefore, using an X-film with a wide shooting area, 3 to 4 nearby teeth including the tooth to be examined can be photographed at the same time. However, if X-ray film is used, imaging processing must be performed after shooting to present the image. Therefore, in dental treatment in recent years, the same method is used to take pictures of the examined teeth with a CCD sensor for imaging and imaging that can sense X-rays, and after electronic processing, a well-reproducible image is produced. Moreover, if a CCD sensor is used, not ...
