Occlusal film-holding assembly for photographing dental images and method of using the same

The present invention relates to an occlusal film-holding assembly and a method of using the same, in particular to an occlusal film-holding assembly for taking dental images, and a method of using the occlusal film-holding assembly to reduce discomfort and improve photographic accuracy at the same time.

When people visit dentist clinics in large hospitals or small dental clinics, they are usually requested by dentists or assisting medical staff for initial visits, routine examinations, or even abnormal examinations of the teeth in the oral cavity. In a safe isolation room or space equipped with professional digital X-ray photography equipment, to take X-ray images of oral teeth or roots, so that dentists can understand the occlusion, growth status, and relative distribution of the patient's roots and teeth. , so that the dentist can make correct medical diagnosis and follow-up related treatment according to the X-ray image after shooting.

At present, the methods of taking tooth or root apex X-rays can be mainly divided into ring X-ray photography and root apex X-ray photography. Ring X-ray photography is to take X-rays around the patient's mouth after the patient is positioned. Photography, although it can quickly obtain a more comprehensive image of the teeth and root apex, but the clarity is insufficient. If you need to get a clearer view of the teeth or root apex in some areas, apical X-ray photography is often used, which is a direct An imaging film (also known as a direct digital imaging tablet) used to display the results of X-ray irradiation is covered with a protective cover, placed in the patient's mouth to be photographed at the location of the local teeth to be photographed, and sent by a dentist, medical staff or patient Shoot by positioning yourself with your hand.

Among them, in order to increase the efficiency of fixing the position, in the apical X-ray photography of the tooth, an auxiliary device is often used to clamp the X-ray film to position it, and the current method of taking the tooth apical X-ray film is to use The X-ray film holder includes a positioning frame and a clamping portion. The positioning frame and the clamping portion are connected through a base. When in use, the X-ray film is firstly clamped to the clamping portion, and Put the holding part into the patient's mouth, and then fix it by the patient opening his mouth and clenching the X-ray film with his teeth, and finally place the lens on the positioning frame to fix the X-ray machine Shoot from the shooting angle.

However, whether pressing by hand or the X-ray film holder will cause a high degree of foreign body sensation in the patient, and it is easy to feel vomiting, and there will also be problems such as easy drooling; The root canals are often arranged three-dimensionally. Therefore, if the shooting angle is not adjusted properly, it is easy to have the overlapping phenomenon of the root and root canal in some tooth images, which will affect the diagnosis of the dentist. Therefore, the adjustment of the shooting angle requires a high degree of height. Professionalism and sufficient experience, but no matter whether it is pressed by hand or positioned with the 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 needs to be adjusted again. One or more fine-tuning is performed to capture X-ray images that meet the needs; however, such repetitive troubleshooting will increase the number of X-rays taken, which in turn exposes the patient to multiple X-rays and increases the risk of cancer, etc. .

In conclusion, it is really necessary to develop a dental image capturing device and its using method that can improve the comfort of taking X-ray images of teeth or root apex, and at the same time increase the correct positioning of X-ray films and increase the ease of operation. sex.
