Description

Tray type dental film shooting auxiliary device

Technical Field

The utility model relates to the technical field of oral cavity images, in particular to a tray type dental film shooting auxiliary device.

Background

Dental film photography is an indispensable part of clinical oral disease diagnosis and treatment. In order to obtain true and accurate tooth information, a parallel projection technology and a diagonal projection technology are generally adopted in clinic. Because the alveolar bone, gum and ridge in the oral cavity are blocked, the dental film is difficult to be parallel to the long axis of the tooth in the oral cavity, so a split-angle line projection method is generally adopted, the principle is that the dental film is tightly clung to the surfaces of the crown and the gum and is obliquely put into the oral cavity of a patient, X-rays are perpendicular to the angle bisectors of the angles between the dental film and the long axis of the photographed tooth, and the images of the tooth and the tooth on the dental film are respectively two sides of the isosceles triangle by utilizing the principle that the two waists of the isosceles triangle are equal, so that the images of the tooth are truly projected on the dental film.

The current photographing method comprises the following steps: 1. the dental film is placed at the correct position in the mouth, so that a patient can press the dental film by using an index finger or a big mother and child, and the X-ray bulb is aligned to the dental film for shooting, so that the discomfort such as nausea and vomiting of the patient is not caused and the photographic quality is affected because the finger is required to extend into the mouth of the patient; 2. the X-ray positioner comprises a light sheet clamping part, a connecting rod and an X-ray guide ring, wherein the X-ray guide ring is connected with the light sheet clamping part through the connecting rod, the plane of the X-ray guide ring is parallel to the angular bisector of the included angles between the dental sheet and the teeth, the light sheet clamping part clamps the dental sheet to stretch into the oral cavity to enable a patient to bite, the X-ray ball tube is vertically aligned with the X-ray guide ring when photographing, the X-ray positioner on the market is mainly made of hard plastics, the adaptation degree of the X-ray positioner to the oral cavity of a human body is poor, repeated adjustment is needed, the biting is difficult, and soft tissue tenderness of the patient is easily caused.

Disclosure of utility model

The utility model provides a tray type dental film shooting auxiliary device which is matched with the oral cavity of a human body, is easy to position a dental film, reduces shooting difficulty and ensures shooting effect.
