System and method for collecting and using vehicle data. Crash data is received from a plurality of vehicle monitoring devices and added to a crash data database. The database is updated with additional information gathered from specific crashes. The crash data is correlated based upon a vehicle type parameter. Crash data parameters associated with one or more injury severity thresholds are identified. Alternatively, crash data parameters associated with one or more vehicle damage severity thresholds are identified. Injury and property damage estimates for subsequent crashes are made based upon the information collected in the crash database.

A system, apparatus, device, tools and method is provided for the insertion of improved anatomically corrected modular design anterior and posterior dental implants, the apparatus including a root component and a head / abutment component, wherein the root component is inserted into the jawbone using precision surgical guide tools in combination with self-limiting surgical templates and a precision adjustable clamping device.

A process for cutting or splitting at least one optical fiber at a predetermined angle, wherein the fiber is introduced into a holding and positioning device and is cut by a pulsed laser beam.

Method for planning and performing dental treatments including an acquisition phase of a set of data relating to the position, to the conformation and to the dimension of at least one site inside the oral cavity of a patient who has to undergo a dental treatment and relating to the conformation of at least one portion of the patient's face; a design phase of a virtual prototype of at least one dental prosthesis that can be fitted at the site during the treatment, starting from the set of data and by means of a software program implemented on a computer; a determination phase, by means of the software program and starting from the set of data and from the virtual prototype of the dental prosthesis, of at least one virtual model suitable for visually reproducing the portion of the face following the fitting of the dental prosthesis; a preparation phase of the site by means of a dental instrument, with the assistance of the software and starting from the virtual prototype of the dental prosthesis and from the virtual model before the installation and the manufacture of the dental prosthesis.

A milling system for creating a cavity in a bone includes a drive shaft, a frame for carrying a cutter and a cutter for cutting the cavity. The drive shaft has a proximal end and a distal end forming a portion of a drive joint for coupling the drive shaft to a cutter. The frame includes a frame shaft and a cutter mount, mounting a cutter at a first angle. The mount includes a bearing bracket extending laterally from the frame shaft to a bearing receiving a portion of a cutter and maintains the received cutter oriented at the first angle during rotation. The cutter has a head forming a portion of drive joint for coupling the cutter to a drive shaft. The cutter is received in the mount at the first angle and the drive shaft forms a second angle with the longitudinal axis less than the first angle.

A milling system is disclosed for creating a cavity in a bone. The cavity has a cross section which has a generally triangular profile having a first side generally parallel with an axis of the bone and a second side forming an acute angle with the first side. The cavity is contiguous with a pre-existing conical cavity in the bone. The system comprises a drive shaft, a frame for carrying a cutter and a cutter for cutting the cavity. The drive shaft has a proximal end configured for coupling to a drive means and a distal end configured to form a portion of a drive joint for coupling the drive shaft to a cutter. The frame includes a shaft and a cutter mount for mounting a cutter at a first angle approximating the acute angle with respect to the shaft. The mount includes a bracket extending laterally from the shaft to a bearing configured to receive a portion of a cutter and maintain the received cutter oriented at the first angle during rotation. The cutter has a head configured to form a portion of a drive joint for coupling the cutter to a drive shaft. The drive shaft is coupled to the cutter to form the drive joint. The cutter is received in the mount at the first angle and the drive shaft forms a second angle with the longitudinal axis less than the first angle.

A controller controls an electronic appliance. The electronic appliance has a display. The controller employs a video camera to photograph an image of a user and converts the image into a mirror image. The controller generates an operational image including operation buttons, overlays the operational image on the user's image, and displays the images on the display. In the displayed images, the user moves his or her hand onto one of the displayed operation buttons and bends the fingers of the hand to select the operation button. This selecting operation is detected by a detector of the controller, and information about the selected operation button is supplied to a processing unit, which outputs control signals corresponding to the selected operation button.

Method and apparatus for preparing bone and cartilage transplants for the reconstruction of the acetabulum, femoral head, or both with tissue engineered osteochondral constructs or and osteochondral allograft transplant.
