Description

Oral cavity dental film photography guiding fixer

Technical Field

The utility model relates to a photographic guide fixer of oral cavity dental film.

Background

Dental film photography is one of the indispensable methods in clinical diagnosis and treatment of oral diseases.

In order to obtain true and accurate tooth information, parallel projection technology and diagonal projection technology are generally adopted clinically. The dental plaque is difficult to reach inside the mouth parallel to the long axis of the tooth due to the blockage of the alveolar bone, gums and carina in the mouth. Therefore, the angular line projection method is generally adopted in China, the principle is that a dental film is obliquely placed in the oral cavity of a patient in a manner of being tightly attached to the surfaces of a dental crown and a gum, X-rays are perpendicular to an angular bisector of an included angle between the dental film and a long axis of a photographed tooth, and images of the tooth and the tooth on the dental film are respectively two sides of an isosceles triangle by utilizing the principle that two sides of the isosceles triangle are equal, so that the image of the tooth is really projected on the dental film. The traditional photographing method is that a doctor places a dental film at the correct position in the mouth and orders a patient to fix the dental film with the index finger or the mother and son. The patients need to put fingers into the mouth of the patients, so that the patients are easy to feel discomfort such as nausea and vomiting; meanwhile, the requirements on the disinfection of the hands of doctors are more strict, and cross infection is easily caused; failure to take a picture due to patient's lack of knowledge of the dental film requirements, possibly being fixed out of position or displaced; in addition, the method requires the irradiator to accurately evaluate the angle between the dental film and the long axis of the tooth, and has high technical requirements.

Based on these deficiencies, a variety of dental film retainers and film holders have been developed. At present, various related products are available on the market, are all made of hard plastics, have the defects of large volume, hard texture and the like, and are easy to cause discomfort such as soft tissue tenderness, nausea, vomiting and the like of patients. And no differently sized dental film retainers are designed for differences in adult and child arch sizes. Therefore, a dental film fixer which is small in size, round and soft in texture and is suitable for the size of a dental arch is needed in clinic.
