Abstract

The invention discloses an oral three-dimensional processing and modeling print system, and relates to the field of stomatology. The system comprises a handheld scanner, a system processor and a 3D print device, wherein the handheld scanner is connected with the system processor through a flexible connecting line; the system processor is connected with the 3D print device; the handheld scanner is divided into an observation part and a handheld part which is rotatably connected with the observation part; the observation part is U-shaped and comprises an inner top part, a front inside part and a rear inside part; a grating projector is arranged on the inner top part; the grating projector extends to the front inside part and the rear inside part; 4 CCD lenses are symmetrically arranged on two sides of the grating projector; and the front inside part and the rear inside parts are provided with tooth holders. Compared with the prior art, the system can directly and conveniently carry out comprehensive three-dimensional scanning on the teeth in oral cavities, so as to instantly obtain the three-dimensional information of upper and lower jaw teeth and then print the tooth structures according to the three-dimensional information of the teeth.

Description

technical field [0001] The invention relates to the field of stomatology, in particular to a three-dimensional scanning technology for oral cavity. Background technique [0002] Oral X-ray film is the routine oral disease examination method, and general tooth root inflammation, tooth fracture, and bone condition can be better reflected. But its limitation is that it can only be projected from a fixed direction, and some lesions are not easy to be found due to the overlapping of tissues. Furthermore, oral CT can be used for monitoring. Oral CT collects data in a spiral manner around a section of the lower jaw to obtain three-dimensional information of the oral cavity. Oral CT scanning has a wide coverage, which is convenient for image reconstruction in various ways and angles, and can be reconstructed arbitrarily and retrospectively. Both of these inspection methods require huge fixed equipment, and it takes a long time to prepare for an inspection, which cannot meet the re...
