The utility model provides a dental bite paper taking box, which relates to the technical field of bite paper storage and comprises two sleeves, the two sleeves are fixedly mounted on the surface of the inner wall of the top of an operation box, extension rods are slidably connected into the sleeves, and cutting knives are fixedly mounted at one ends, far away from the sleeves, of the extension rods. Extension plates are fixedly installed on the surfaces of the two sides of the cutting knife, springs are fixedly installed between the extension plates and the inner wall of the top of the operation box, a pressing rod is fixedly installed between the two extension plates, a cutting table is fixedly installed on the inner bottom face of the operation box, and a cutting groove is formed in the surface of the cutting table. The cutting knife is arranged in the operation box, so that the situation that a user is possibly scratched due to the fact that a knife head is exposed is avoided, meanwhile, after cutting, the occlusion paper is abutted against the pressing roller, the phenomenon that the broken end of the occlusion paper is brought back into the circular cylinder by the remaining occlusion paper is avoided, and subsequent use is guaranteed.

The utility model provides an accessory structure for invisible correction, which comprises an accessory body fixedly arranged on a dental surface, and the accessory body is T-shaped and / or L-shaped. The T-shaped accessory body comprises a vertical arm and a horizontal arm, the vertical arm is fixed with a tooth surface and forms a moment fulcrum on a gingival side / a coronal side, the horizontal arm is fixedly arranged at one end of the vertical arm and extends in a near-far middle direction to generate a bidirectional lever effect, and a connecting part is arranged at the joint of the vertical arm and the horizontal arm; the L-shaped accessory body comprises a long arm leading stress conduction in the horizontal direction and a short arm fixedly connected with one end of the long arm and used for limiting in the vertical direction, the problem of dentition adduction of a protuberant surface type is solved, occlusal plane adjustment is achieved through the synergistic effect of the accessory body and an implant anchorage, and the effect of improving the surface type of a patient is achieved.

The invention relates to the technical field of dental restoration, in particular to a digital complete denture manufacturing method based on a surface scanning calibration occlusal plane and related equipment. The method comprises the following steps: performing three-dimensional reconstruction on a maxillofacial surface of a target object based on oral cavity scanning data and face scanning data to obtain a maxillofacial surface three-dimensional model; the maxillofacial three-dimensional model comprises a face three-dimensional area and an oral cavity three-dimensional area; determining a first occlusal plane in the oral three-dimensional area by taking the oral anatomical mark point as a reference; determining a face reference line according to the face three-dimensional area; and calibrating the first occlusal plane according to the facial reference line to obtain a second occlusal plane, and modeling an upper jaw denture and a lower jaw denture along the second occlusal plane. According to the method, the second occlusal plane can be obtained through automatic calibration of the face reference line, digital modeling of the upper jaw denture and the lower jaw denture is performed on the second occlusal plane, the occlusal plane does not depend on manual confirmation through a traditional occlusal support, and intraoral operation steps during denture repair are reduced.

Certain aspects of this disclosure provide a method for determining a virtual occlusion. The method may include obtaining a 3D representation of a patient's first and second mandibles. The method may also include, with the 3D representation, displaying in a graphical user interface (GUI) the initial position of the first mandible relative to the second, defined by six predetermined degrees of freedom with respect to a coordinate system fixed relative to the first mandible. The method may also include receiving input from the user regarding changes in at least one degree of freedom and automatically adjusting at least one other degree of freedom to minimize the vertical distance from the control point to the origin, thereby determining a virtual occlusion. The method may also include displaying, in the GUI, the first and second mandibles in the determined virtual occlusion.

The invention relates to the technical field of tooth occlusion calculation, in particular to a tooth occlusion calculation method and system and a storage medium. Acquiring specified position information based on the updated first preset model according to the to-be-detected tooth picture, the specified position information including a first position frame and a second position frame, and the first position frame and the second position frame being overlapped; acquiring a contact ratio according to the first position frame and the second position frame; and matching in preset types according to the contact proportion, and further obtaining the tooth occlusion type of the to-be-detected tooth corresponding to the corresponding to-be-detected tooth picture. The method is convenient to operate, time is saved, and the user can pay attention to the tooth problem of himself / herself in time.
