A medical implant and a method of implanting a medical implant are described. The medical implant can be elongate and for fixation in a patient, and can include an apical bone anchoring portion for bone apposition, and an unthreaded coronal portion. The coronal portion can have a length (L) exceeding or equaling a length (L) of the apical portion. The apical portion can have a maximum outer diameter (D) that is equal to or larger than a maximum outer diameter (D) of the coronal portion. In a method of implanting a medical implant, an apical part can be affixed in the zygomatic bone, and a coronal part can be positioned outside the maxilla in the mucous membrane.

Medical implant and method of implantation

A medical implant and a method of implanting a medical implant are disclosed. In some embodiments, the medical implant can include an apical bone anchoring portion for bone apposition and an unthreaded coronal portion. The coronal portion can have a length (L) exceeding or equaling a length (L) of the apical portion. Further, in some embodiments, the apical portion has a maximum outer diameter (D) that is equal to or larger than a maximum outer diameter (D) of the coronal portion. In some embodiments of the method, an apical part of an implant is affixed in the zygomatic bone and a coronal part is positioned outside the maxilla in the mucous membrane.

A combination of a guide sleeve for a surgical template, a drill, and a thread forming tool is disclosed. The guide sleeve has a guide surface for guiding the thread forming tool. The drill has at least one cutting edge for cutting a recess in bone. The thread forming tool has a thread forming section for forming at least one thread in bone, and a guide section for guidance by the guide surface of the guide sleeve, the thread forming section comprising an apical portion, and a coronal portion. A maximum diameter of the apical portion of the thread forming section is smaller than or equal to a maximum diameter of the cutting edge of the drill.

Components for guided threading of bone

In certain embodiments, a combination of a thread forming tool and an implant is disclosed. The thread forming tool can have a thread forming section with a helical thread having at least one cutting surface for cutting a thread in bone. The implant can include a bone apposition surface having at least one helical thread for position at least partially in the thread of the bone. A longitudinal cross-sectional shape of at least a portion of the helical thread of the thread forming section in certain embodiments, substantially corresponds to a longitudinal cross-sectional shape of at least a portion of the helical thread of the implant.

In some embodiments of the method, an apical part of an implant is affixed in the zygomatic bone, and a coronal part is positioned outside the maxilla in the mucous membrane.

Methods, systems, and computer-readable media are disclosed herein for virtually planning a cranial guided surgery in a subject. These include, in some embodiments, generating a first data set based on input data obtained of a physical reference structure having a defined fixed relation to a bone structure of said subject and generating a second data set based on input data obtained of a master structure for a surgical template, where the master structure has a defined relation to said physical reference structure. Further, in some embodiments, a third data set for production of said surgical template can be generated based on the first data set and the second data set, wherein the relation of said physical reference structure to said master structure is preserved.

Repositioning of components related to cranial surgical procedures in a patient

The invention relates to a device for alignment of a first component () and a second component () in a predetermined relation to each other, comprising a transmitter unit () arranged for mounting on said first component () and comprising a light source () for the generation of light radiation () with a predetermined pattern in the direction towards a receiver unit () arranged for mounting on said second component (), where the receiver unit () comprises a detection device () for said light radiation (). The invention is characterised in that said detector device () comprises a first detector () and a second detector (), respectively, which are separated depthwise in relation to said transmitter unit (). The invention also relates to a receiver unit () for the above-mentioned type of alignment, and also a method for such alignment. By means of the invention, an improved alignment of for example belt discs is provided.
