3D Dental Imaging
The construction of a 3D dental work piece in layers with the aid of screen dots freely materializing in space is a technical process and is known as stereo lithography. The production of one or several simultaneously produced pieces is usually fully automatic and based on data generated by a computer. The video shows the production of one such work piece. The process of producing a stereo lithography is like the working of a printer except that with stereo lithography, the material is printed in 3D rather than in 2D. The 3D model that is being constructed in the video depicts the model of a lower jaw. The information for this model was created from the patient’s CT data. The victim of a traffic accident, lost not only all her teeth but part of the jaw as well. With the help of a 3D dental model developed by stereo lithography, the missing jaw part would be reconstructed. Using the stereo lithography 3D model, an absorbable foil is formed which will serve as a place-holder for the bone substitute material, which will be inserted into the jaw to reconstruct the missing jaw. The technique of making a 3D model using stereo lithography has helped tremendously in bone reconstructive surgery, required as a fall out of accident or disease. The video demonstrates in detail the use of stereo lithographic 3D models in re-constructive surgery. Here you see a LIVE OPERATION 3D Stereolithography.
