The invention relates to the technical field of information, and particularly provides a complete denture arrangement virtual simulation method and system, and the method comprises the steps: obtaining the medical record data of a user; the medical record data comprises edentulous jaw soft and hard tissue data, jaw bone data, alveolar ridge morphological parameters, jaw position relation data and facial feature data; determining an initial dental arch curve based on the medical record data; inputting the initial dental arch curve and preset aesthetic parameters into a preset deep learning model to obtain a plurality of initial tooth arrangement schemes; screening the plurality of initial tooth arrangement schemes according to tooth arrangement constraint conditions to obtain tooth arrangement schemes meeting constraints; the tooth position and angle of each tooth arrangement scheme meeting the constraint are adjusted until the preset occlusion balance condition is met, and the first tooth arrangement scheme is obtained, so that the tooth arrangement scheme efficiency of the complete dentures can be improved on the premise that the quality of the tooth arrangement scheme of the complete dentures is guaranteed.

Examples in the present disclosure relate to hand chirality estimation. Tracking data captured by one or more sensors associated with an extended reality (XR) device is processed to determine positions of a plurality of joints of a hand of a person. A reference vector is generated based on a first subset of the positions. The first subset of the positions includes positions of at least two metacarpophalangeal joints. A plurality of bending angles is determined based on at least a second subset of the positions. Each bending angle represents an angle between a respective pair of articulating bones that is measured in relation to the reference vector. An estimated chirality of the hand is identified based on the plurality of bending angles. Operation of the XR device is controlled using the estimated chirality of the hand.

The embodiment of the invention discloses femur detection information generation equipment and a computer readable medium. A particular embodiment of the device comprises: a data receiver configured to receive femur image data; the processor is configured to execute the following steps: preprocessing the femur image data; carrying out region segmentation processing on the preprocessed femur image data; generating intramedullary nail filling degree data; generating a support classification result; generating pinnacle distance data; generating neck-shaft angle data; standardized intramedullary nail filling degree data, standardized pinnacle distance data and standardized neck shaft angle data are obtained; generating femur feature information; generating thighbone detection information; a memory configured to store femur detection information; and a transmitter configured to transmit the femur detection information to a target server. According to the embodiment, the response time of the thighbone detection information generation equipment during thighbone detection can be shortened.

The invention discloses an angle-adjustable or deployable multi-stage anchoring insertion sheet system, and relates to the technical field of medical instruments, the angle-adjustable or deployable multi-stage anchoring insertion sheet system comprises a hollow box body, and the upper surface and the lower surface of the box body are each provided with at least one insertion sheet outlet; the at least one group of inserting piece driving mechanism is arranged in the box body and is used for generating linear driving force; the at least two insertion sheet assemblies are accommodated in the box body in an initial state, and each insertion sheet assembly is in driving connection with the insertion sheet driving mechanism; according to the intervertebral fusion cage, the secondary anchoring part capable of moving relative to the basic anchoring part is arranged, so that the anchoring angle or the opening degree of the fusion cage can be adjusted according to a vertebral form operation of a patient after the fusion cage is implanted, the adaptability to different anatomic forms is improved, and a more flexible anchoring scheme is provided for an intervertebral fusion operation.
