The utility model relates to the technical field of medical equipment, concretely relates to oral cavity radiation image gathers and uses opening stopper.

Background

The mandible of a person has multidirectional movement capabilities of protrusion, up-down, left-right and the like when the mandible is opened due to anatomical structures of masticatory muscles and temporomandibular joints. When the maxillary dentition and the mandibular dentition are not in contact, it is difficult to maintain a certain position still for a long time.

In the oral cavity imaging examination, the shooting of CBCT examination and the high-precision three-dimensional image resolution capability thereof become the necessary means in the most common diagnosis and treatment processes such as temporomandibular joint disease diagnosis, oral cavity bone mass implantation measurement, 3D printing guide plate manufacturing and the like. During CBCT examination, the patient is required to be kept still for a long time to acquire images, and during temporomandibular joint examination, joint movement of the patient's mandible in different opening positions is often observed. However, during the examination, it is difficult for the patient to remain still in a certain oral position, especially for edentulous patients in normal resting occlusal position for a long period of time. Therefore, when the lower jaw of a patient moves during acquisition, artifacts exist in the acquired images, the acquired images are adversely affected, the diagnosis of temporomandibular joint diseases or the normal measurement of the bone mass in oral cavity implantation is affected, and even the images need to be acquired again. For example, in the 3D printing guide plate fabrication, the problem of the need to re-acquire images occurs when the designer has difficulty separating the upper and lower teeth in the software due to the artifacts created in the CBCT images by the high density enamel.

These clinical requirements all require that the patient needs to be assisted to keep the lower jaw still during the opening when taking the CBCT examination, and currently, no CBCT examination assisting device which can be individually adapted to different patient sizes and different opening positions exists.
