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 method of 3D printing nitinol to create a patient-specific device to facilitate the establishment of a normal stress-strain trajectory in grafted bone.

Methods, devices, and manufacture of the devices for musculoskeletal reconstructive surgery

A method for checking a component to be produced in an additive manner, having the steps of mechanically exciting at least one additively constructed layer of the component during the additive production of the component, measuring a mechanical response signal of the component, and displaying a warning and/or interrupting the additive production of the component if the mechanical response signal lies outside of a specified tolerance range. A device for the additive production of a component, includes a device for mechanically exciting the at least one additively constructed layer of the component, a measuring unit for measuring the mechanical response signal of the component, and a control unit. The control unit is designed to display the warning and/or interrupt the additive production if the mechanical response signal lies outside of a specified tolerance range.

A method for additive production of a component, which includes the additive construction of the component on a component platform having an opening, wherein, during the first part of the additive construction of the component an auxiliary structure is produced additively around the opening of the component platform. The method further includes the introduction of a device through the opening into a cavity defined by the auxiliary structure, wherein, during a second part of the additive construction, following the first part of the additive construction, properties of the component to be produced are influenced and/or measured by the device. A component is produced by the method and an apparatus for the additive production of the component, includes the component platform having the opening and the closure.
