Abstract: Dental imaging systems are provided for imaging upper-teeth and lower-teeth arches in an oral cavity, the dental imaging system including an outer arch-shaped structure and an inner centralizer structure coupled to each other, and being installable in a predefined position with the upper-teeth and lower-teeth between the outer arch-shaped structure and a camera hub of the inner centralizer structure. The outer arch-shaped structure has outer cameras arranged in such a way that, when the dental imaging system is in predefined position, the outer cameras focus on a front side of both the upper-teeth and lower-teeth. The inner centralizer structure has a support structure and the camera hub, the support structure holding the camera hub and the camera hub including inner cameras arranged in such a way that, when the dental imaging system is in predefined position, the inner cameras focus on a back side of both the upper-teeth and lower-teeth.
