The invention refers to an implant device (10) for treating an orbital floor fracture. The implant device (10) is foldable in a first direction between a folded state and an unfolded state and is plastically extendible in a second direction from an unextended state to an extended state. In the extended state, the implant device (10) has an extension in the second direction that is longer than a length in the unextended state and equal to or greater than an aperture distance of a human maxillary sinus in an anterior-posterior direction. The invention further refers to a related implantation tool, to a related implantation system for treating orbital blow fractures and to a corresponding implantation method.

A method of designing a craniomaxillofacial implant that is a rigid plate of substantially uniform thickness, including: positioning a surface element of the plate as a departure from a reference location within a base outline, the departure being represented by a fraction of the length of a normal path projected from the reference location to a predetermined soft tissue layer at a supported location within an anatomic region of interest, and the fraction being based upon a required patient-specific support at the supported location.

The invention relates to resorbable crosslinked form stable membrane which comprises a composite layer of collagen material and inorganic ceramic particles containing 1.5 to 3.5 weight parts of inorganic ceramic for 1 weight part of collagen material, sandwiched between two layers of elastic pretensed collagen material (collagen material that has been stretched such as to be in the linear/elastic region of the stress-strain curve), the collagen material comprising 50-100% (w/w) collagen and 0-50% (w/w) elastin, and has shape and dimensions suitable for use in human tissue regeneration outside the oral cavity in rhinoplasty, postlateral spinal fusion or orbital reconstruction.

A surgical device for retracting tissue of a subject while offering lighting and suction means integrated into the same device. This device is useful in many different surgical procedures, including those requiring precise tissue retraction in small openings of a subject, such as facial orbital fracture repair.

Method for manufacturing an auxiliary device suitable for the manufacture of a patient customized implant comprising the steps of: 1) obtaining 3D image data, preferably a CT of a defect site of a patient's anatomy (1); 2) generating a computer model of the defect site based on the 3D image data and 3D generic reference data by using image processing techniques; 3) virtually reconstructing the defect site; 4) generating a computer template (30) which represents an auxiliary device (40) that is suitable for sizing, shaping and positioning of alloplastic implants; and 5) manufacturing an auxiliary device (40) using 3D printing. Furthermore, there is provided a method for manufacturing a patient customized implant using the auxiliary device and a method for the reconstruction of a particular anatomy by using the manufactured patient customized implant.

A prosthetic implant includes an anterior surface, configured for at least partial contact with an underside of a patient's facial soft tissue. A posterior surface is oppositely placed to the anterior surface. The posterior surface is configured for at least partial contact with a patient's facial bony tissue when the anterior surface is in at least partial contact with the patient's facial soft tissue. An implant body is defined by the anterior and posterior surfaces and extends transversely therebetween. A selected portion of the posterior surface has a texture that mechanically differs from a texture of a majority of the anterior surface.

Embodiments of the invention described herein thus provide implants and methods for manufacturing an implant having an outer layer that is porous. The porous outer layer can help encourage tissue ingrowth into the implant. The porous outer layer may be positioned around a core structure this is solid or that has a hollow interior. The core structure may be spherical or any other appropriate shape for a medical implant.

Embodiments relate generally to channel implants used for surgical reconstruction and/or repair. Certain embodiments of the channel implants are designed for craniofacial surgery, reconstruction, and/or augmentation. More specifically, some embodiments find particular use in orbital reconstructive surgery, such as repair of the orbital floor or supraorbital ridge (brow ridge). Embodiments also relate to methods for using and for manufacturing the channel implants disclosed.

The present application relates to an eye socket covering grid that includes a curved main body with an external closing edge, a lower side which, in the implanted state, is facing the bone or bones forming the eye socket, and an upper side distant from the lower side, wherein at least one optically identifiable linear channel for representing at least one insertion vector is formed on the upper side. The application also relates to a method for producing such an eye socket covering grid, in particular an eye socket covering grid adapted in a patient-specific manner.

Various embodiments of craniofacial implants, surgical instruments, and techniques are described to provide improved surgical results.
