Disclosed is a fixing bone plate, which comprises a plate body. The plate body is provided with a plate main part and a locking portion passing through the plate body. The plate main part is connected to the locking portion at the corresponding two ends of the plate body. The fixing bone plate also comprises an attachment portion. The attachment portion is provided with a bone attachment surface. The attachment portion is disposed on the other side of the locking portion. The plate body can be manufactured by using a metal laser additive manufacturing technique or a 3D metal printing technique. The fixing bone plate can be accurately positioned and stably combined with a human bone according to morphological characteristics of bones.

The invention relates to a plate (1) for insertion into the palate, the plate (1) having wings (4) on both sides of an imaginary center plane (9) running perpendicular to the plate (1), the wings being designed such that they bear against the palate at least in regions. The two webs (3) run on both sides of the central plane (9), so that a free space (6) running between the webs (3) is formed for receiving the vomer (13).

The present disclosure relates to a method of manufacture of a dental implant for a molar, including acquiring, structural data corresponding to bones of the facial skeleton, the bones of the facial skeleton being proximate the molar, selecting, as a dental implant fixation surface, a surface of the bones based upon a determined thickness of the bones, generating, based on the selected dental implant fixation surface, a contoured surface of the dental implant, and fabricating, based upon an instruction transmitted by processing circuitry, a bone plate extending from a buccal end of a cylindrical plate of the dental implant, the cylindrical plate having support lattices extending therefrom, at least one support lattice of the support lattices being arranged on a lingual end of the cylindrical plate, the cylindrical plate having an opening in a central region thereof, the opening being configured to receive a dental post.

The present disclosure concerns a subperiosteal dental implant for receiving at least one replacement tooth of a patient, the subperiosteal dental implant comprising an implant frame superposable to at least a section of a jaw hone of the patient, the implant frame having a bone-facing surface at least partially contacting the jaw hone of the patient when the implant frame is superposed thereto, and an opposed gum-facing surface, the implant frame having at least a section along which a cross-section profile includes a base defining at least partially the bone-facing surface and at least partially the gum-facing surface, a ridge protruding from the base and defining at least partially the gum-facing surface, and a first shoulder and a second shoulder that are both defined on the gum-facing surface of the base, each one being located on a respective side of the ridge.

A distraction system can include a distraction implant comprising a magnetic element and a distraction mechanism configured to expand the distraction implant in response to rotation of the magnetic element. The distraction system can include an external device comprising a motor configured to rotate a driver magnet while in a powered state, the driver magnet configured to rotate the magnetic element, a computing device configured. The computing device can be configured to measure an electrical current drawn by the motor during rotation of the driver magnet. The computing device can be configured to maintain the motor in the powered state in response to a mean value of the electrical current being greater than or equal to a mean value threshold, and a standard deviation value of the electrical current being less than or equal to a standard deviation threshold.

An implant device includes a connection bridge to cause retraction or distraction of first and second bone segments. The connection bridge overlaps a surface of the segments and exerts a force to one of the first and second bone segments by translation motion of connection bridge. The bridge includes a first insertion structure mountable to the first segment and has at least one rack. An internal repositioning tool has a pinion to engage the rack causing the motion. A locking mechanism selectively locks the motion of the repositioning tool. A second insertion structure mounts to the second segment or a third bone segment between the first and second segments. The second structure includes a housing to house at least one of the pinion and the lock mechanism and receive a portion of the at least one rack to engage the at least one the pinion and the lock mechanism.

Exemplary cutting and alignment guide assemblies for use in microsurgical, plastic surgical, otolaryngological, maxillofacial, orthopedic, dental, or other surgical procedures include a first section configured to engage a first bone graft section, a second section configured to engage a second bone graft section, a first fixation mechanism configured to couple the first section with the first bone graft section, and a second fixation mechanism configured to couple the second section with the second bone graft section. The first section and the second section can be coupled via a hinge mechanism. Neo-mandible assemblies for implantation at a native mandibular defect of a patient can include a cutting and alignment guide coupled with one or more bone graft sections. In some cases, bone graft sections include bone segments from a fibula of the patient.

A bone graft system includes a two-dimensional mesh sheet sized and shaped to, when folded along fold lines, form a three-dimensional graft containment structure configured to be packed with a bone graft material for placement within a target area of a bone, the mesh sheet including a first end flap connected to a remaining portion of the mesh sheet via a first fold line and a second end flap connected to the remaining portion of the mesh sheet via a second fold line, a third fold line extending from the first fold line to the second fold line so that the remaining portion is configured to be wrapped around folded first and second end flaps to form the graft containment structure, the first and second end flaps substantially corresponding to a profile of the target area of the bone.

A device used in conjunction with fixation hardware to provide a two-stage process to address the competing needs of immobilization and re-establishment of normal stress-strain trajectories in grafted bone. A method of determining a patient-specific stress/strain pattern that utilizes a model based on 3D CT data of the relevant structures and cross-sectional data of the three major chewing muscles. The forces on each of the chewing muscles are determined based on the model using predetermined bite forces such that a stiffness of cortical bone in the patient's mandible is determined. Based on the stiffness data, suitable implantation hardware can be designed for the patient by adjusting external topological and internal porous geometries that reduce the stiffness of biocompatible metals to thereby restore normal bite forces of the patient.

A patient-specific artificial temporomandibular joint is proposed. The patient-specific artificial temporomandibular joint includes: a temporal bone coupling part including a fixing body that is fixed to the temporal bone of a patient and a head receiver that is detachably coupled to the fixing body and provides a close-contact curved surface being open downward; and a mandible coupling part including a coupling body that is fixed to the mandible of a patient and a head that has a spherical shape and is supported by the coupling body in contact with the close-contact curved surface of the head receiver. The patient-specific artificial temporomandibular joint is manufactured by 3-D printing on the basis of shape data of the temporal bone or the mandible of a patient, so a good implanting effect is provided and the patient quickly recovers. Further, worn parts can be partially replaced, thus there is a little burden of maintenance.
