A computer-implemented method, a system and a computer program is disclosed, which comprise virtual planning of a medical procedure of a patient. The medical procedure comprises providing a patient configured bone structure in a body portion of the patient. Based on an input of a final result of the medical procedure, the bone structure may be modified by various tools and methods, such a bone implants, bone distractive methods, etc. Production data based on the virtual planning is generated that is configured for subsequent use in production of the bone structure or a medical product, which medical product is devised for use in the medical procedure, and devised for arrangement in the patient for facilitating the medical procedure. The virtual planning of a medical procedure comprises providing position data for a position of at least a part of a prosthesis component in relation to the body portion, and virtual planning of a modification of a boundary surface at the body portion as a function of the position data.

Computer implemented planning and providing of mass customized bone structure

A method and system useful for planning a dental restorative procedure of a patient and for producing at least one dental restoration or product related thereto to be used in the dental restorative procedure are disclosed. Input data from different sources, e.g. 3D data from a CT scan of a patient with a dental impression tray including a previously prepared dental impression of the patient in the patient's mouth, is matched with data from a high resolution 3D scan of the same dental impression. The resulting data is for instance matched by fiducial markers arranged at the dental impression tray.

Method and system for dental planning and production

A scanning structure having at least one surface with a shape adapted to conform to a portion of a craniofacial space is described. The scanning structure includes at least one surface object, which is at least partly identifiable from a first set of data, and where a first coordinate is identifiable based on the surface object. The scanning structure includes at least one volume object, which is at least partly identifiable from a second set of data, and where a second coordinate is identifiable based on the volume object. The surface object can be arranged in relation to the at least one volume object such that the first coordinate and the second coordinate have a pre-defined relationship to each other.

Method and system providing improved data matching for virtual planning

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

A system comprises a computer appliance designed to receive, and to present on screen, first information transmitted from identification equipment and based on detection of a jaw bone structure. Modification information which can be introduced into the computer appliance shows a visual dental bridge structure applied on the jaw bone structure with associated teeth and dentine. Orientations for implants are also shown. The computer appliance produces a CAD file which is based on the first information and the modification information. The file is received in a stereolithography machine which issues second information which can be processed in the equipment for production of the physical template which includes through-bores for sleeves which define implant orientation. A working model is produced with the aid of the physical template. The invention also relates to an arrangement of a template produced by stereolithography and by means of information from the computer appliance.

System and arrangement for production and insertion of a dental bridge structure

A drilling assembly is provided for drilling a hole into a zygoma of a patient. The assembly can comprise a template, an extension unit, a drill guide unit, and first and second drills. The template can be configured for orientation within a patient's mouth and can comprise a guide sleeve having a longitudinal axis extending towards the zygoma when fitted on the patient. The extension unit can include a central bore and be slideably received within the guide sleeve. The drill guide unit can also include a central bore of a different diameter than that of the extension unit. The first drill can be slideably received within the central bore of the guide sleeve. The second drill can have an outer diameter different than that of the first drill and can be configured to be slideably received with the central bore of the drill guide unit.
