Abstract:
An integrated system is described in which digital image data of a patient, obtained from a variety of image sources, including CT scanner, X-Ray, 2D or 3D scanners and colour photographs, are combined into a common coordinate system to create a virtual three-dimensional patient model. Software tools are provided for manipulating the virtual patient model to simulation changes in position or orientation of craniofacial structures (e.g., jaw or teeth) and simulate their effect on the appearance of the patient. The simulation (which may be pure simulations or may be so-called "morphing" type simulations) enables a comprehensive approach to planning treatment for the patient. In one embodiment, the treatment may encompass orthodontic treatment. Similarly, surgical treatment plans can be created. Data is extracted from the virtual patient model or simulations thereof for purposes of manufacture of customized therapeutic devices for any component of the craniofacial structures, e.g., orthodontic appliances.
Abstract:
1. Ein Verfahren zur Bereitstellung eines patientenspezifischen Implantats wird in mehreren Schritten mit einem System in weitgehend automatisierter Form durchgeführt. Eine Verletzung eines Körperteils eines Patienten wird mittels eines bildgebenden Verfahrens gemessen, ein Messdatensatz des verletzten Körperteils erzeugt, der einem mehrdimensionalen Abbild der Verletzung des Körperteils entspricht, die mit dem bildgebenden Verfahren ermittelt worden ist. Aus dem Messdatensatz wird ein mehrdimensionales Modell des verletzten Körperteils erzeugt, wobei mit Hilfe des mehrdimensionalen Modells des verletzten Körperteils ein Modell des gesunden Körperteils erzeugt werden kann, welches insbesondere die Kräfte enthält, welche durch eine Dauerbelastung auf das Körperteil wirken. Ein mehrdimensionales Modell des Implantats wird erstellt, welches an das mehrdimensionale Modell des Körperteils angepasst wird, sodass ein modifiziertes mehrdimensionales Modell des Implantats erhalten wird. Das modifizierte mehrdimensionale Modell des Implantats wird aus mindestens einem Modulelement generiert. Die Festigkeit des Modulelements wird so ausgewählt, dass sie mindestens der Festigkeit bei einer maximalen Belastung des Körperteils entspricht, sodass die Belastung, der das Implantat im Gebrauchszustand über seine gesamte Lebensdauer maximal ausgesetzt ist, kleiner als die Dauerfestigkeit des Modulelements ist.
Abstract:
In a method and system for producing an implant, the latter is designed with one or more surfaces extending in the longitudinal direction of the implant. Two or three production stages can be used. In one stage, either a topography with a long wave pattern is produced by means of cutting work, or laser bombardment or further cutting work is used to produce a topography with an intermediate-length wave pattern. In addition, an oxidation process or shot-peening or etching is used to produce an outer layer. When using two of said production stages, said cutting work or said laser bombardment or further cutting work is followed by the oxidation process or the shot-peening or etching method. When using all three production stages, cutting work is followed by laser bombardment, or further cutting work, which in turn is followed for example by the oxidation process. The invention also relates to an implant which is produced using the method and is identified, ordered and produced using the system. The invention permits effective treatment of different implant situations.
Abstract:
An orthopedic implant manufacturing method. The method includes preparing a pre-operative surgical plan for a specific patient, the surgical plan including a three-dimensional image of a patient's joint indicating at least one resection plane, communicating the surgical plan to a surgeon of the patient, and receiving approval of the surgical plan and the resection plane by the surgeon. The method also includes providing automated osteophyte/protrusion removal control for surgeon manipulation, receiving a modified three-dimensional image of a patient's joint indicating an osteophyte/protrusion removal and a recommendation for a corresponding selected orthopedic implant from the surgeon, and requesting manufacture of the selected orthopedic implant.
Abstract:
The invention relates to an optical lens shaped into the form of a shroud and having a light-permeable front side (11) and a side wall (12) adjacent thereto, wherein the side wall (12) and the front side (11) constitute different components of the optical lens (1) that are bound together through injection molding.
Abstract:
An implant with one or more outer surfaces extending in its longitudinal direction. The outer surface comprises one or more outer threads and an underlying wave pattern with long waves or intermediate-length waves. An oxide layer, a shot-peened layer or an etched layer is arranged on the top of said wave pattern. The long waves and preferably also the intermediate-length waves extend substantially in said longitudinal direction. The wave pattern with the long waves has a trough depth in the range of 75 to 150 µm. The wave pattern with the intermediate-length waves has a trough depth in the range of 10 to 75 µm.
Abstract:
A patient monitoring system comprises a sensor, and a processor in communication with the sensor. A memory device is electrically coupled to the processor. The memory device has stored therein a plurality of instructions which, when executed by the processor, cause the processor (a) to monitor output from the sensor to determine the number of cycles of use of the orthopaedic joint of a patient, and (b) to generate a message to the patient indicative of a need to initiate communication with an orthopaedic care provider if the number of cycles of use of the orthopaedic joint exceeds a predetermined threshold value.

Abstract:
A system for monitoring implant sensor data over a cellular network (18) includes a portable computing device (16), a controller (14), and an orthopaedic prosthesis (12) configured to communicate with the controller over the cellular network. The orthopaedic prosthesis includes one or more implant sensors (104) configured to generate implant sensor data and a cellular transmitter or transceiver (106) configured to transmit the implant sensor data to the controller over the cellular network. The controller or the orthopaedic prosthesis may initiate the cellular communication. The implant sensor data is transmitted to the portable computing device by the controller. The portable computing device is configured to display the implant sensor data, or indicia thereof, to a user. The portable computing device and controller may also be used to update one or more programs executed by the orthopaedic prosthesis.
Abstract:
A system (10) for transmitting implant data includes an orthopaedic implant (52), a wireless receiver (14), and a processing circuit (12) electrically coupled to the wireless receiver. The orthopaedic implant is configured to transmit implant identification data and implant sensor data to the wireless receiver in response to a power signal. The orthopaedic implant may transfer the data over, for example, a wireless network. The processing circuit receives the implant identification data and the implant sensor data from the wireless receiver and is configured to retrieve patient-related data from a database based on the implant identification data. The processing circuit may also be configured to update a patient queue, assign a patient room to a patient, and/or transmit the patient-related data and the implant sensor data to a client machine located in the patient room.
