Description
Technical Field
The utility model relates to an oral cavity positioner that shoots belongs to oral cavity medical equipment field.
Background
Colorimetry is one of the key steps in oral aesthetic restoration, and it is important to obtain accurate color information. Clinically, the color comparison is mainly carried out by depending on a dental color comparison plate, and the commonly used color comparison plates are a Vita 3D Master and a Vita classic color comparison plate which can basically meet most of the clinical requirements. However, for teeth with complicated colors, such as tetracycline pigmentation teeth and dental fluorosis teeth, the color information exceeds the coverage of the conventional color chart, and the information transmission between the doctor and the technician needs image data to assist in the process. The more reference data a technician has, the more the confidence that the simulated prosthesis is made. Therefore, clinical photography of the oral cavity has been produced and is increasingly becoming a requisite skill for oral aesthetic restoratives.
Clinicians are directly facing the patient and have full knowledge of the patient's information, while technicians are facing the model and the information is severely disparate. To produce a highly simulated prosthesis, the physician needs to accurately communicate color information of the patient's teeth to the technician. The digital photos are used as special media for color information communication, the consistency of the standard of the photos must be kept, and the shooting conditions are completely the same, namely different people and different time periods can shoot the same photos, so that the photos are comparable at any time. The photography standard for dental colorimetry, which is commonly defined in the industry, is to photograph teeth at the same distance and angle, with the same magnification, with the shutter speed, aperture and sensitivity fixed under the standard light source (5500 k). The photos taken in this way have better comparability before, during and after aesthetic repair, objective and repeatedly reproducible photo data are beneficial to clinical research of doctors and academic communication among the same lines, and are also beneficial to color verification after repair by technicians and doctors, so that the technical level of both medical and technical parties is improved, and the satisfaction degree of patients is improved. Thus, normative clinical photography is a fundamental requirement for aesthetic repair.
Most digital photography of the oral cavity is now done at the chair side of the office. The usual position is for the patient to lie in a dental chair and for the physician to stand beside the chair for photography, as shown. With the updating of the digital single lens reflex, the lens is heavier, and the device is heavier due to the weight of a special lighting system, namely a flash lamp, so that a photographer can bear heavy load, the photographing time is long, the camera is easy to shake hands, and the camera is difficult to persist for a long time. Because of the special requirements of the colorimetric photos, the camera setting is generally in a manual mode, and the physician needs to repeatedly move the body for focusing, which can cause the physician to be very tired.
