FIELD: medicine.

SUBSTANCE: invention relates to medical equipment. Dental imaging device to obtain an image of the intraoral cavity, comprising: an elongated handle having a proximal end and a distal end, a head on the distal end of the elongated handle, having a size and shape for selective insertion into the intraoral cavity, a pair of side scanning cantilevers connected to the head opposite to each other, wherein each of the pair of side scanning cantilevers comprises an upper scanner and a lower scanner connected therewith to obtain an image of at least a portion of the intraoral cavity, and a guide having a size and shape for substantially continuous engagement with the intraoral cavity, while simultaneously substantially shifting scanner at a relatively suitable distance from the intraoral cavity, when the dental image former moves relative to the intraoral cavity during image acquisition. Dental imaging device for imaging an intraoral cavity, in a second embodiment comprising: an elongated handle, a head on the distal end of the elongated handle, a pair of arc-shaped side scanning cantilevers, a central roller coupled rotatably with the head and configured to provide a roller support for the dental imaging device above the intraoral cavity, and a lateral roller guide connected to each of said pair of arc-shaped side scanning cantilevers at an angle of about 30–45 degrees, wherein each of said central roller and said side roller guides has a size and shape for substantially continuous engagement with the intraoral cavity, simultaneously substantially shifting the scanners to a relatively suitable distance from the intraoral cavity, when the dental image former moves relative to the intraoral cavity during imaging. Dental imaging device for displaying an intraoral cavity, in a third embodiment comprising: an elongated handle, a head on a distal end of the elongated handle rotatable relative to the elongated handle by means of a handle accord or hinge joint, a pair of flexible side scanning cantilevers arranged generally opposite each other, side plate connected to each of said pair of flexible side scanning cantilevers at angle of 30–45 degrees to it, and a middle plate connected to the head and configured to provide a sliding support for the dental imaging device above the intraoral cavity, wherein said side plates and said middle plate have a size and shape, providing substantially continuous engagement with the intraoral cavity while simultaneously significantly shifting the scanners to a relatively suitable distance from the intraoral cavity, when the dental image former moves relative to the intraoral cavity during image acquisition. Dental imaging device for imaging an intraoral cavity, in a fourth embodiment comprises: an elongated handle, a head on one end of the elongated handle, a pair of flexible arc-shaped lateral scanning cantilevers extending outward from the elongated handle, a compass connected to each of the flexible arc-shaped lateral scanning cantilevers and tracking their angular orientation, a front, angled platform coupled to the head and carrying the front scanner at angle of 30–60 degrees, and a rear platform located at an angle connected to the head and carrying a rear scanner at angle of 30–60 degrees, and a guide. Dental imaging device for imaging an intraoral cavity, in a fifth embodiment comprising: an elongated handle, a head at a distal end of the elongated handle, a pair of arched side scanning cantilevers, an inclusion sensor comprising an emitter in one of the pair of arched side scanning cantilevers and a sensitive element in the other of the pair of arched side scanning cantilevers, wherein said radiator and said sensitive element are generally aligned such that a beam generated by the emitter can be received by the sensing element when the dental imaging device is not used, and is generally blocked by an intraoral cavity during use, and a guide. Dental imaging device for imaging an intraoral cavity, in a sixth embodiment comprising: an elongated handle, a rotary head connected to the distal end of the elongated handle by means of a hinge joint, thus providing simultaneous longitudinal, lateral, and/or vertical movement of 360 degrees of rotary head relative to elongated handle, at that, rotary head includes platform, guide. Dental imaging device for imaging an intraoral cavity, in a seventh embodiment comprising: an elongated handle, a head on a distal end of the elongated handle, at least one side scanning console, a guide, wherein the guide comprises a roller or a plate having a surface providing a sliding movement above the intraoral cavity. Dental imaging device for imaging an intraoral cavity, in an eighth embodiment comprising: an elongated handle, a head on a distal end of the elongated handle, one side scanning console which monitors the angular orientation of said at least one side scanning cantilever relative to the flexible joint, and a guide. Dental imaging device for imaging an intraoral cavity, in a ninth embodiment comprising: an elongated handle, a head on a distal end of the elongated handle, at least one side scanning console, and a side roller guide or a side plate. Dental imaging device for imaging an intraoral cavity, comprising: an elongated handle, a head on the distal end of the elongated handle, a front median scanning console and a rear median scanning console, connected to the head, at least one side scanning console, a guide. Dental imaging device for imaging an intraoral cavity in the tenth embodiment comprises: an elongated handle, a head on a distal end of the elongated handle, at least one side scanning console, a guide. Dental imaging device for imaging an intraoral cavity, in the eleventh embodiment comprises: an elongated handle, a head on a distal end of the elongated handle, a pair of fixed scanning cantilevers fixed to the head of the elongated handle, wherein each of the pair of fixed scanning cantilevers has a scanner coupled therewith to obtain an image of at least a portion of the intraoral cavity, a front plate and a back plate mounted on the head, and a guide.

EFFECT: technical result of the disclosed invention is higher efficiency of producing dental images.
