Detailed Description
The present invention is further illustrated by way of the following examples, which are not intended to limit the scope of the invention.
Example 1
Referring to fig. 1 and 2, the present embodiment provides a dental modeling apparatus based on a 3D imaging technique.
The dental modeling apparatus includes a 3D camera 11, a dental fixture, and a processor.
The oral cavity fixer comprises a support and a plurality of contact pieces for contacting the oral cavity inner surface.
Specifically, the oral cavity fixator of the present embodiment includes a C-shaped mouth gag including two C-shaped grooves 12. The C-shaped groove is the contact. That is, the oral cavity fixator includes two contact members, respectively two of the C-shaped grooves.
The C-shaped groove is used for propping open the lips and the cheeks to separate the lips from the teeth, so that the 3D camera can shoot the teeth conveniently.
The support member comprises a chevron-shaped connector 13, the chevron-shaped connector 13 connecting the outside of the groove walls of the two C-shaped grooves.
The support piece further comprises a slide rail 14, the 3D camera is arranged in the slide rail, and the slide rail extends into the oral cavity when the oral cavity fixator opens the upper teeth and the lower teeth.
In this embodiment, the slide rail is arranged in the middle of the herringbone connecting piece, and two ends of the herringbone connecting piece are connected with the C-shaped groove.
The oral cavity fixer struts upper and lower teeth through the supporting piece and the C-shaped groove, when the oral cavity fixer struts the upper and lower teeth, the 3D camera stretches into the oral cavity through the supporting piece and sets a shooting direction to align to the teeth from the oral cavity, and the processor is electrically connected with the 3D camera.
Through the slide rail, the 3D camera can also aim at the tooth from the outside of the oral cavity and shoot, specifically, the shooting direction of the 3D camera and the included angle of the slide rail are 45 degrees when shooting the tooth in the oral cavity. The upper teeth and the lower teeth are respectively shot by 45-degree angles, and images of the tooth surfaces and the tooth tips can be obtained.
