Abstract: A method of producing a dental splint comprising the steps of: obtaining a set of 3D surface data, the 3D surface data representing a surface of a patient's oral situation, and generating a support structure model in dependence on the 3D surface data, and producing the dental splint in dependence on the support structure model, wherein a 3D distance map image of the 3D surface data is used to generate the support structure model.

Abstract: In embodiment of the invention provides a method of producing a dental splint comprising the steps of: obtaining a set of 3D surface data, the 3D surface data representing a surface of a patient's oral situation, obtaining a support structure model describing a dental splint configured to fit to a portion of the surface of the patient's oral situation, modifying an apical edge of the support structure model in dependence on the 3D surface data, producing the dental splint in dependence on the modified support structure model.

Abstract: An embodiment of the invention provides a method of producing a surgical template comprising the steps of: obtaining a set of 3D surface data, the 3D surface data representing a surface of a patient's oral situation, obtaining a support structure model describing a surgical template configured to fit to a portion of the surface of the patient's oral situation, obtaining planned bore position data, the planned implant position data describing the longitudinal axes of a set of one or more planned implant bore holes relative to the 3D surface data, automatically modifying the support structure model to provide support material for guide holes in the support structure model corresponding to the one or more planned implant bore holes, producing the dental splint in dependence on the modified support structure model.

Abstract: A method for deriving shape information of a person's skull and dentition, including the steps of: taking an impression of the person's dentition, taking a first scan of the person's head, while the person is wearing the impression, taking a second scan of the impression alone, combining the scans, deriving the shape information from the combined scans. Advantageously the method further includes the step of taking a third scan of the person's head alone without the impression.

Abstract: A method for capturing the shape of a dento-maxillofacial object out of volumetric image data of the dento-maxillofacial object is described. The method includes performing a segmentation of the volumetric image data with at least one calculated segmentation parameter indicative of the distinction between the dento-maxillofacial object and its background and derived from a calibration procedure. The method further includes capturing the shape of the dento-maxillofacial object from the segmented volumetric image data.

Abstract: A system and method for pre-operatively obtaining a prediction of a post-operative image of at least part of a body is disclosed. A 3D pre-operative description is determined of at least part of a body, and a pre-operative 2D photograph is acquired of the at least part of the body from any viewing position. The 3D pre-operative description is matched with the pre-operative 2D photograph, and a deformation field is determined for deforming the 3D pre-operative description. A predicted post-operative image of a 3D post-operative description of the at least part of the body is derived by means of the deformation field and the pre-operative 2D photograph.
