The embodiment of the invention provides a complete denture arrangement method and device, and belongs to the field of data processing. The method comprises the steps that upper and lower jaw oral scanning data and silicone rubber oral scanning data of occlusion recording silicone rubber are aligned, and preprocessed CBCT data and the aligned upper and lower jaw oral scanning data and silicone rubber oral scanning data are superposed and integrated to obtain first superposed data; furthermore, the first overlapping data and the face scanning data of the tooth arrangement object in the multiple face states are overlapped and integrated to obtain second overlapping data, and a tooth arrangement scheme is obtained based on the second overlapping data. Therefore, standardized tooth arrangement is realized, and standardized inspection is facilitated, so that high tooth arrangement cost can be reduced, and tooth arrangement time consumption can be reduced. According to the invention, tooth arrangement is carried out by integrating various data with abundant tooth arrangement information, so that a tooth arrangement scheme is more adaptive to a tooth arrangement object, and the degree of adaptation between the tooth arrangement scheme and the tooth arrangement object can be improved.

One of the aims of the invention is to provide a dental stabilisation device which prevents a patient, during a dental procedure, from easily releasing their teeth from said device. To this end, the inventor proposes a dental stabilisation block which comprises internal channels that open onto the faces of the dental stabilisation block which come into contact with the patient's teeth. These internal channels are connected to an inlet via which a bite registration material can be injected, said material being intended to harden and be moulded to the patient's teeth. In this way, when the bite registration material has hardened and has moulded around the teeth, it becomes more difficult for the patient to release their teeth from the dental stabilisation block.

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 maxillomandibular registration tray of the present invention includes a maxillary portion that can be fixed by adding material to the maxillary portion of a patient, a mandibular portion that can be fixed by adding material to the mandibular portion of a patient, and connecting portions that connect the inner surface of the maxillary portion and the inner surface of the mandibular portion to each other. The distance between the maxillary portion and mandibular portion is adjustable after separating the maxillary portion and mandibular portion. Therefore, the maxillomandibular registration tray first applies materials to the maxillary portion and mandibular portion to acquire maxillomandibular registration, and then separates the maxillary portion and mandibular portion to adjust the distance using screws to set the vertical height, establish the mandibular position, and add bite registration materials to the maxillary and mandibular tray space to finally acquire precise maxillomandibular registration.

Dental bite registration and vertical dimension positioning device

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.

One object of the present invention is to provide a tooth stabilization device that prevents patients from easily releasing their teeth from the device during dental surgery. To this end, the inventors have proposed a tooth stabilization block that includes internal channels opening onto the surface of the block that contacts the patient's teeth. These internal channels connect to an inlet through which a bite registration material, designed to harden and mold to the patient's teeth, can be injected. This makes it more difficult for the patient to release their teeth from the tooth stabilization block once the bite registration material has hardened and molded around the teeth.

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.

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.
