Description

The present invention relates to a dental shade guide holder capable of holding a plurality of dental shade guides by overlapping a plurality of dental shade guides used when selecting a tooth material having a color tone with excellent aesthetics when producing a dental prosthesis. Is.

  In general, tooth materials excellent in aesthetics such as dental resin and dental porcelain used when producing dental prostheses such as inlays and crowns are used for the teeth or adjacent teeth of dental prostheses to be produced ( If the dental prosthesis to be produced is an inlay or the like, a tooth having a cavity, if the dental prosthesis to be produced is a crown or a bridge or the like, the adjacent tooth, hereinafter simply “neighboring tooth etc.” The tooth prosthesis is different depending on the type of tooth material so that the tooth prosthesis does not become unnatural due to the color difference between the tooth prosthesis and For various types of tooth materials, tooth materials having different colors of several to tens of colors are prepared in advance.

  A dentist who asks a dental technician who is a specialist to produce a dental prosthesis to make a dental prosthesis usually confirms the difference in the color tone of each tooth material, which usually has many different colors. A dental prosthesis can be prepared from a number of tooth materials of different colors by using a plurality of color samples having the same color tone as that of each tooth material, so-called dental shade guide. The tooth material is selected and determined with the color tone that most closely matches the color tone of the target tooth.

  As such a dental shade guide, for example, a color-viewing body imitating the shape of an artificial tooth formed in the same color tone as the color tone of the tooth material is fixed on the surface of one end of a handle portion made of a belt-like plate. A dental shade guide (see, for example, Patent Document 1) or a color-viewing body imitating the shape of an artificial tooth formed on the surface of one end of a handle portion made of a belt-like plate in the same color tone as that of the tooth material. There are dental shade guides (for example, see Patent Documents 2 and 3) and the like that are pivotally supported, and these dental shade guides usually indicate the color tone of the color viewing body, for example, A1 and A2. Etc. are displayed on the handle portion or the like.

  Such a dental shade guide is generally a dental shade guide storage body (for example, Patent Document 1) capable of storing a plurality of dental shade guides in parallel in the width direction of each handle portion. (See ~ 3.) The dental dentist who asks a dental technician to make a dental prosthesis is used in such a dental shade guide to create a number of differently colored teeth. When selecting a tooth material with a color tone that most closely matches the color tone of the tooth for which the dental prosthesis is to be prepared, select a number of dental shade guides that may be more suitable than the dental shade guide housing. By taking out the book and directly comparing the color tone of the patient's neighboring teeth with the color tone of the dental shade guide, the dentist himself can select and decide the tooth material with the most harmonious color tone. Take out several dental shade guides that appear to be more suitable than the departmental shade guide housing, and place the color shade body of these dental shade guides in the vicinity of the patient's adjacent teeth, etc. Take a picture of the patient's adjacent teeth and the color shade body of the dental shade guide at the same time using a digital camera, etc., and send it to the dental technician. Or requesting the selection of a tooth material of a different color.

  In this way, when directly comparing the color tone of the patient's adjacent teeth and the color shade of the dental shade guide, the photograph of the patient's adjacent teeth and the color shade main body of the dental shade guide is simultaneously photographed. In this case, the dental shade guides may be held one by one and moved so that the coloration main body comes to a position in the vicinity of the patient's adjacent teeth, etc. In order to more accurately select and determine the most harmonious tooth material by making it easy to compare the color tone of the main body with the color tone of the adjacent teeth, usually a plurality (2-5) The dental shade guide of this book) is positioned in the vicinity of the patient's adjacent teeth or the like so that the color-viewing bodies simulating the shapes of the artificial teeth are arranged in parallel.

  However, when positioning a plurality of dental shade guides in the vicinity of the patient's adjacent teeth and the like so that the color-viewing bodies simulating the shapes of the artificial teeth are arranged in parallel, the dental shade guide is formed of a belt-like plate. In the case where a tinting body imitating the shape of an artificial tooth formed in the same color tone as that of the tooth material is fixed to the surface of one end of the handle portion, the shape of the artificial tooth as shown in FIG. In a state where the color-viewing bodies simulating each of them are oriented in substantially the same direction and the handle portions are arranged in parallel in the width direction, a plurality of dental shade guides are placed next to the patient with one hand. There is a problem that multiple dental shade guides must be held in an extremely unstable state because it must be held in the vicinity of the dentition, etc. tooth When taking a photo with the color guide of the shade guide for the camera at the same time, hold the handle part with one hand in such an unstable state and hold the camera etc. with the other hand. Not only is it difficult to work because it has to be operated to shoot, but it also means that the shake cannot occur in the dental shade guide and camera, and it is not possible to take clear pictures. In addition, it is an important factor in selecting and deciding the most harmonious color tooth material by taking the handle of the dental shade guide and the hand holding these dental shade guides during shooting. There was also a problem in that a part of the surrounding gingiva, lips, etc. of a patient's neighboring teeth, etc. were blocked.

  In addition, the color shade main body simulating the shape of an artificial tooth using a dental shade guide storage body that can store a plurality of dental shade guides as described above in parallel in the width direction of each handle portion, respectively. A dental in which a plurality of dental shade guides are stored in a state in which they are oriented in substantially the same direction and the respective handle portions are arranged in parallel in the width direction, and the plurality of dental shade guides are stored. A method of holding the shade guide housing for the patient so as to be positioned in the vicinity of the patient's adjacent teeth or the like has been performed, but in this method, the dental shade guide housing itself may be held, so that it is stable. Since multiple dental shade guides can be held in the state, the workability when photographing by operating a camera or the like is improved, but a wide range of dental shade guides is collected when photographing. Compared to the method in which the handle portions of the dental shade guide are held in parallel in the width direction by the amount of the body, the surrounding area around the patient's adjacent teeth, etc., is obstructed. There has been a problem that the area of parts such as gingiva and lips becomes large.

  On the other hand, when positioning a plurality of dental shade guides in the vicinity of the patient's adjacent teeth, etc., so that the color-viewing bodies simulating the shapes of the artificial teeth are arranged in parallel, the dental shade guide is made of a belt-like plate In the case where a color-viewing body simulating the shape of an artificial tooth is rotatably supported on the surface of one end of the handle portion, the color-viewing body simulating the shape of each artificial tooth as shown in FIG. Is rotated at a substantially right angle around its axis, that is, by rotating the color viewing body so that the tooth axis direction of the color viewing body and the longitudinal direction of the handle portion are substantially perpendicular, A plurality of dental styluses can be placed by hand, etc., with each handle facing each other so that each color viewing body is aligned in the longitudinal direction of the handle. shade Id can be held so that it is located in the vicinity of the patient's adjacent teeth, etc., so if you hold multiple dental shade guides in this way, it will be blocked around the patient's adjacent teeth, etc. It is possible to minimize the area of parts such as gingiva and lips.

However, since the length of the handle portion of such a dental shade guide is usually the same, in the state where the respective handle portions are stacked so that the respective color-viewing main bodies are juxtaposed in the longitudinal direction of the handle portion, End portion of the handle portion of the dental shade guide (the dental shade guide whose color right body is located on the rightmost side in FIG. 16) whose handle portion is located on the most surface side, and its handle portion is located on the most back side The distance from the end of the handle portion of the dental shade guide that is located (the dental shade guide whose color-viewing main body is located on the leftmost side in FIG. 16) is the distance that each color-viewing main body is separated. Since the handle portions are overlapped with each other in the longitudinal direction of the handle portion, when the handle portions are held by hand, the handle portions are While maintaining the state of being bent, it is necessary to hold the overlapping portion of the handle portion or the entire end portion of the handle portion, which is not only very difficult to hold, but usually the handle portion is a smooth surface. Since the surfaces of the handle portions that are overlapped with each other are slippery, the artificial surface formed in the same color tone as the tooth material on the surface of one end of the handle portion made of the belt-like plate described above. Compared to the case where a plurality of dental shade guides, each of which is fixed in color in the width direction of each handle portion, are held in parallel with each other in the width direction of each handle portion, one hand is more unstable. In this case, it is necessary to operate the camera etc. with the other hand while holding each handle part, so that the work is very difficult. There is also a guide and in camera to camera shake is've caused a problem that it is not possible to capture sharp photos, by a child would further shift slips face each other superimposed the handle portion, a dental shade guide There was also a problem that it could be dropped in the patient's mouth or floor.
