A method, apparatus, electronic device, and storage medium for facial bone binding

ActiveCN116310002BEnhanced binding effectSolve the problem of poor fitting effectAnimationTotal factory controlFacial boneGround truth
This application provides a facial skeleton rigging method, apparatus, electronic device, and storage medium. The facial skeleton rigging method includes: binding facial bones to facial mesh data in the initial state of the character to be constructed, obtaining a first binding result; loading a historical skeleton controller and first controller parameters of the historical skeleton controller; calculating the facial bone position using the first controller parameters, obtaining the vertex position of the first facial mesh; and optimizing the first binding result based on the vertex position of the first facial mesh, the facial mesh data, and the first controller parameters to obtain a second binding result. Calculating the facial bone position using controller parameters and optimizing the first binding result using the vertex position of the facial mesh and the facial mesh data as ground truth significantly improves the rigging effect of facial skeleton rigging.

A new type of head external support for maxillofacial bone traction

ActiveCN116172676BReliable retention effectlow costAgainst vector-borne diseasesExternal osteosynthesisFacial boneCalvaria
This invention discloses a novel external cranial support for maxillofacial bone traction, comprising: two lateral fixation members, each fixed to the temporal region above the ear on both sides of the skull by three first screws; a cranial top fixation member, fixed to the cranial top by two second screws; two angle rulers, each fixed to one of the lateral fixation members, with a sliding member on the side of each angle ruler and a telescopic member on the angle ruler, one end of which is coaxially fixed to the angle ruler and the lateral fixation member, and the middle of which is fixed to the sliding member; and a solid metal rod, each end of which passes through the other end of the two telescopic members, with two pulling members on the solid metal rod, the other ends of which are connected to the facial bones. This invention achieves more reliable fixation while significantly reducing costs.

Dual predrilling module for an osteotomy procedure and an additional orthopedic procedure

PendingCA3319127A1Articular surfacesFacial bone
A dual predrilling module for drilling a fixation hole and a repair tunnel in a bone is provided. The dual predrilling module includes a body comprising a bone interface side comprising a bone contacting surface engageable with a surface of the bone or a fixation plate engaging side removably engageable with a fixation plate, and an operative side opposite the bone interface side or the fixation plate engaging side. The dual predrilling module further includes an osteotomy drill guide to create a fixation hole according to a fixation hole pathway, and a repair drill guide extending outwardly to create a repair tunnel according to a repair tunnel pathway, the repair tunnel pathway being determined to intersect a predetermined cutting plane intended to create an osteotomy and to extend across the bone to open to an articular surface of bone, without intersecting the fixation hole pathway.

Maxillofacial region soft tissue model generation method for orthodontic process

The invention belongs to the technical field of maxillofacial region image analysis, and provides a maxillofacial region soft tissue model generation method for an orthodontic process. Respectively constructing a current finite element data block and a reference finite element data block, and analyzing the distribution condition of various soft tissues of the reference finite element data block corresponding to the current finite element data block to obtain a distribution probability set of the various soft tissues in the current finite element data block; segmenting the current finite element data block based on the distribution probability set to obtain a plurality of sub-finite element data blocks and a sub-distribution probability set; and finally, on the basis of the sub-distribution probability set, soft tissue distribution consistency between the sub-finite element data blocks and all neighborhood sub-finite element data blocks is analyzed, the sub-finite element data blocks are combined, and a more accurate soft tissue model structure of the current patient can be obtained.
