Oral cavity scanning instrument

Abstract

The invention discloses an oral cavity scanning instrument. The oral cavity scanning instrument comprises a lower cover body (1), wherein the lower cover body (1) comprises an integrated connected handle part (2) and a transparent scanning part (3) which adopts the shape similar to that of the oral cavity; a horizontal moving unit which can be used for enabling one end of a moving plate (8) to move from left to right is arranged on the inner bottom surface of the handle part (2); the other end of the moving plate (8) is rotatably connected with a fixing shaft; a front-and-rear direction movingunit which moves in the length direction of the moving plate (8) is arranged on the moving plate (8), and is connected with a scanning arm (14) which extends in the direction towards the scanning part (3); a first camera (15) is connected to a free end of the scanning arm (14). According to the oral cavity scanning instrument provided by the invention, the oral cavity full scanning can be completed in one time without moving of the oral cavity scanning instrument.

Description

technical field [0001] The invention relates to an oral scanner, in particular to an oral scanner capable of scanning and photographing teeth, belonging to the technical field of electronic appliances. Background technique [0002] With the development of 3D graphic image technology, dental scanning is generally a graphic image acquisition scan at present. The structure of the existing oral scanner is generally the structure described in Chinese Patent No. 201610009864.9. For example, it includes a scanner host and a dental imaging head. The dental imaging head is small, so that it can be easily put into the oral cavity. During the scanning process, the doctor only needs to Hold the scanner host and make the dental scour head slide on the patient's teeth, and then the acquired 2D image can be reconstructed by 3D technology to obtain an accurate tooth scan. [0003] That is to say, the scanner host and the dental view head of the above structure are mobile, and the doctor co...

Problems solved by technology

[0003] That is to say, the scanner host and dental speculum head of the above structure are mobile, and the doctor controls the movement of the dental speculum head on the teeth by adjusting the angle of the scanner host. It needs to be controlled by human experience, and it is difficult to perform a full scan of the inside of the oral cavity, that is, the moving speed of the dental speculum head and its length in the oral cavity directly affect the scanning effect of the teeth

[0004] In addition, existing oral scanners generally do not have an oral support device. During the scanning process of the dental speculum head sliding on the teeth, it is difficult for the patient to keep the oral cavity in an active open state. After the patient keeps the oral cavity open for a period of time, the Muscles are prone to spasm or fatigue. Proper occlusal training is required to relieve the above symptoms. The oral scan can only be continued after the above symptoms are relieved. This undoubtedly brings a very uncomfortable scanning experience to the patient, and it is difficult to complete a full oral scan at one time.

[0005] In addition, in the absence of any oral support device, when the dental speculum head slides on the teeth for scanning, it is easy to stimulate the secretion of saliva in the oral cavity, so that the amount of saliva secretion is greatly increased, and the surface of the teeth is covered with a layer of saliva. Reflection will also affect the scan effect
