An advanced intraoral photogrammetry device is designed to capture photo images and 3D video simultaneously, allowing for instant full-arch scanning, detailed color mapping, and precise bite registration.

A bite fork or bite tray device with channels to facilitate flow of impression material through the substrate while held inside a patient's oral cavity to obtain bite registration or impression consisting of full or partial teeth impression or full or partial gum impression or alveolar bone or alveolar process or alveolar ridge or a combination of these. A process for use of the system for prescription or design or manufacture of an appliance by providing the necessary steps.

The invention relates to the technical field of digital oral diagnosis and treatment, and discloses an intelligent diagnosis device and method for recording and analyzing oral occlusion, the device comprises an occlusion recording module, a first color developing agent, a second color developing agent and an image analysis module, the occlusion recording module is composed of an upper-layer sheet, a medical silica gel layer and a lower-layer sheet which are arranged in a separable manner from top to bottom; wherein the outer surfaces of the upper sheet and the lower sheet are respectively provided with a super-hydrophobic coating. Before occlusion, color developing agents with different colors are coated on the surfaces of corresponding coatings; and after occlusion separation, upper and lower tooth occlusion color marks are formed. The image analysis module obtains a double-sided image, identifies a positioning mark in a medical silica gel layer, performs spatial registration on upper and lower layer color marks, and establishes a corresponding relation of occlusion contact points; and then extracting an average gray value and a pixel area of each point, substituting the average gray value and the pixel area into a pre-stored gray and pressure conversion function, and calculating relative occlusion pressure information of each point. The method corresponds to the device. Synchronous and quantitative recording and analysis of occlusion contact of the upper jaw and the lower jaw are achieved.

An impression system is disclosed for enabling the creation of dentures in one-visit. The impression system may include an upper impression tray, an upper wax bite registration coupled to the upper impression tray, a lower impression tray, a lower wax bite registration coupled to the lower impression tray, and one or more arc-shaped wax plates configured to be coupled to at least one of the upper or lower wax bite registrations. Each of the upper and lower impression trays may include a convex outer surface and a concave inner surface with the associated wax bite registration coupled to the convex outer surface. The one or more arc-shaped wax plates may be configured to adjust distance between the concave inner surfaces of the upper and lower impression trays, generally associated with an occlusal vertical dimension of the patient.

The invention provides an intraoral occlusion registration method and device, electronic equipment and a computer program product. The method comprises the following steps: acquiring an upper dental arch model and a lower dental arch model of an upper dental arch and a lower dental arch in a non-occlusion state; acquiring an occlusion model of the upper dental arch and the lower dental arch in an occlusion state; respectively registering the upper dental arch model and the lower dental arch model with the occlusion model to generate a first dental arch model; determining one or more rigid modules in the first dental arch model; and registering the one or more rigid modules with the occlusion model to generate a second dental arch model. In this way, the shape of the dental arch is changed when the dental arch is subjected to occlusion stress, high-precision occlusion reconstruction of the upper dental arch and the lower dental arch in the actual stress state is achieved through two times of registration, and therefore the accuracy and stability of intraoral occlusion registration are remarkably improved.
