This invention discloses a digital complete denture manufacturing method and a digital complete denture, relating to the field of digital oral technology. The invention acquires digital models of the patient's edentulous maxilla and mandible, along with jaw position data. Virtual tooth arrangement and denture base design are completed in computer-aided design software, generating a composite digital model. The base data is converted into CNC instructions, and a five-axis CNC milling machine is used to cut prefabricated material blocks to produce a solid denture base. Matching solid prefabricated dentitions are selected from a prefabricated dentition database, surface-activated, and then bonded and fixed to complete the denture assembly. This method is highly efficient, provides stable precision, and significantly shortens the manufacturing cycle and the number of treatment visits.

This invention discloses a personalized Gothic arch component for dental implant restoration and a method for determining digital jaw position relationships, belonging to the field of medical device technology. The component includes a mandibular tracing needle fixation bracket, a tracing needle, a maxillary Gothic arch tracing plate, and fixing screws. The mandibular tracing needle fixation bracket comprises a Y-shaped tracing needle positioning frame and a personalized implant fixation bracket. The tracing needle is fitted into the central groove of the mandibular tracing needle fixation bracket via a shaft-hole fitting structure. The maxillary Gothic arch tracing plate is U-shaped and adapts to the maxillary dental arch. Both the mandibular tracing needle fixation bracket and the maxillary Gothic arch tracing plate are provided with screw channels for matching fixing screws. The method for determining digital jaw position relationships includes: taking a digital impression; designing and 3D printing the above components using CAD / CAM; determining the vertical distance and centric relationship using the personalized Gothic arch; and transferring the maxillary-mandibular relationship for edentulous full-mouth implant restoration based on occlusal records and electronic facebow data, thereby improving the clinical applicability of the restoration.

The invention relates to an improved guide splint (1) for dental procedures in fully or partially edentulous patients, having a lower face (1a) with an anatomical shape designed to rest on a jaw of the patient and comprising at least one through hole (2) configured to serve as a reference for a dental procedure. The splint (1) of the invention also comprises at least one recess (3) on the lower face of same configured for snap-fit engagement with at least one lug (T) protruding from the gum.

The application relates to the fields of oral medicine and digital manufacturing technology, and discloses a segmented embedded structure digital design and manufacturing method for a toothless jaw implant bridge, which comprises the following steps: collecting and preprocessing multi-modal data of a patient; reconstructing a three-dimensional model and marking key anatomical markers; virtually arranging teeth for the patient and optimizing implant positioning; designing a bridge segmentation and embedded connection structure; performing biomechanical simulation and optimizing structure parameters to obtain an optimized bridge segmentation model; performing digital manufacturing and post-processing; converting the optimized bridge segmentation model into a physical bridge segmentation and performing post-processing; performing clinical trial and completing final prosthesis production; through steps 2, 4 and 5, the balance between biomechanics and clinical experience is realized through stress and comfort double-index control; through bridge segmentation, single-time positioning resistance is reduced, and positioning success rate and positioning accuracy are improved.

The utility model discloses a customized detachable edentulous immediate load-bearing fixed denture, and relates to the technical field of human oral medicines.The fixed denture comprises a plurality of customized implants, retention connectors, corresponding repair bases and repair base inner screws, the lower ends of the customized implants are implanted into alveolar bones, the upper ends of the customized implants are flush with gingiva, and the lower ends of the customized implants are connected with the retention connectors. The retention connector is of a strip-shaped structure, is horizontally laid above the customized implants along the tooth jaw shape and is used for connecting the implants at the planting points into a whole, the repair abutment is arranged above the retention connector, and the repair abutment inner screw is used for penetrating through the retention connector to connect the repair abutment with the customized implants; according to the technical scheme, the implant tooth is suitable for patients with full-mouth or half-mouth tooth loss and free-end tooth loss, immediate implantation, immediate repair and immediate load bearing can be achieved, the repair period is shortened, the difficulty of implantation operation and the risk of repair failure are reduced, and the indications of full-mouth or free-end tooth loss of the implant tooth are expanded.

The utility model relates to the field of oral clinical application, specifically discloses a kind of buccal tongue mucosa pusher and rower of auxiliary mandibular edentulous jaw intraoral scanning, including buccal tongue side pusher and rower, connecting body, hand handle;The buccal tongue side pusher is respectively placed in the buccal side and the lingual side of edentulous jaw alveolar ridge, its form is adapted to the form of alveolar arch, is connected with hand handle by connecting body;The connecting body is upper end horizontal, lower end arc;The hand handle is tetragonal, and end has digital identification.The pusher and rower can effectively separate the soft tissue such as buccal tongue mucosa around edentulous jaw alveolar ridge, prevent the influence of buccal tongue mucosa to oral scanning data, and have certain pusher and rower effect to movable mucosa, can assist to determine mucosa edge, help to obtain the accurate oral scanning data of edentulous jaw;The buccal tongue mucosa pusher and rower structure is simple, easy to operate, and can be placed in the occlusal surface thereof to assist guiding intraoral scanning.
