BITE-BLOCK AND FILM-HOLDING DEVICE

摘要

A bite-block and film-holding device is used with an x-ray film or a digital image sensor and held by a patient between teeth to align with an external camera device for dental radiographic imaging of the patient's teeth. The bite-block and film-holding device includes a disposable film holder having a bite block portion, a film-holding portion made of a plastic material, and a bonding member having a release layer attached thereto; and an aiming assembly having a coupling arm coupled to the disposable film-holder and an aiming ring assembly installed on the camera device and connected to the coupling arm. The aiming ring assembly is adjustable in position for the camera device to face at a right angle to the film-holding portion. After the dental radiographic imaging, the disposable film holder is separated from the aiming assembly and discarded to ensure the patient's oral cavity hygiene and health.
