Description

Bite holding piece assembly for tooth image shooting and use method thereof

The present invention relates to an occlusal holding piece assembly and a method of use thereof, in particular to an occlusing holding piece assembly for dental image shooting, and a method for using the occlusing holding piece assembly to reduce discomfort and improve the accuracy of photography at the same time.

People go to dentist clinics in large hospitals or small dentist clinics. For initial examinations, routine examinations, or even abnormal examinations of teeth in the mouth, they are usually requested by dentists or assisted medical staff and taken to them. In a safe isolated room or space equipped with professional digital X-ray photography equipment to take X-ray images of oral teeth or roots, so that the dentist can understand the patient's root and tooth occlusion, growth status, and relative distribution in the oral cavity. , So that dentists can make correct medical diagnosis and follow-up related treatment courses based on the X-ray images taken.

At present, the methods of taking X-rays of teeth or apex can be divided into ring X-ray photography and apex X-ray photography. Ring X-ray photography is performed around the patient’s mouth after the patient is positioned. Photography, although a more comprehensive image of the tooth and apex can be obtained quickly, but the sharpness is relatively insufficient. If you need to know more about the situation of the tooth or apex in some areas, most of the apex X-ray photography is used, which directly An imaging film (also known as a direct digital image digitizer) used to display the results of X-ray irradiation is wrapped in a protective sleeve and placed in the patient’s oral cavity to be photographed. The dentist, medical staff or patient Take pictures after positioning yourself by pressing with your hands.

Among them, in order to increase the efficiency of fixing the position, in the tooth apex X-ray film photography, an auxiliary device is used to clamp the X-ray film to position it, and the current method of shooting the tooth apex X-ray film is to use The X-ray film holder includes a positioning frame and a clamping part. The positioning frame and the clamping part are connected through a base. When using, the X-ray film is clamped to the clamping part first. Put the holding part into the patient’s oral cavity, and then fix the X-ray machine by opening the mouth of the patient and biting the holder of the X-ray film with the teeth. Finally, the lens is placed on the positioning frame to fix the X-ray machine. Shoot from the shooting angle.

However, no matter whether it is pressed by hand or X-ray film holder, the patient will feel a high degree of foreign body sensation, and will easily feel vomiting, and will also have problems such as easy drooling. Moreover, because of the clinical roots and teeth Root canals are often arranged three-dimensionally. Therefore, if the shooting angle is not adjusted properly, the root and root canal may overlap in part of the tooth image. This will affect the diagnosis of the dentist. Therefore, the adjustment of the shooting angle requires a high degree of Professionalism and sufficient experience, but whether it is pressed by hand or positioning with an X-ray film holder, it takes a long time to adjust the angle, and it is easy to cause the X-ray film to shift and need to be re-positioned. Perform one or more fine adjustments to capture X-ray images that meet your needs; however, such repetitive troubleshooting will increase the number of X-ray film shots, which in turn exposes patients to X-rays and increases the risk of cancer. .

To sum up, it is really necessary to develop a dental imaging device and its use method that can improve the comfort of taking X-ray images of teeth or root tips, and at the same time increase the correct positioning of X-ray films and increase the ease of operation. Sex.
