Abstract: A denture is manufactured in a single visit using a pre-formed dental template chosen from a plurality of different sized dental templates, based on the size of a patient's alveolar edentulous ridge. The dental template includes a base acrylic with prosthetic teeth attached thereto. A viscous material such as an acrylic is added to the selected dental template and the dental template with the added viscous material is placed on the patient's alveolar edentulous ridge. The viscous material is then allowed to solidify to form a rigid or semi-rigid material with the template in proper position in three planes and properly border molded. After solidification a denture is formed that consists of a first base acrylic portion in conterminous relation with a second portion formed of the solidified material that had been added as a viscous material, and with teeth joined to the base acrylic portion.

Abstract: A visualization apparatus and a system for enhancing hand-eye coordination during a medical procedure are provided. The visualization apparatus includes an elongate support member, a head member, an operating head element, and a processor. The head member connected to the elongate support member at a predetermined angle includes an angled wall for mounting a reflector. The operating head element connected to an upper end of the head member mounts and supports an objective lens. The objective lens focuses light from an operating field to a reflector to create an image of the operating field. An eyepiece lens accommodated in the elongate support member or the head member magnifies the created image. The processor operatively communicating with an image receiver processes and transmits the magnified image to a viewer. The orientation of the magnified image on the viewer is similar to the orientation of the operating field, thereby enhancing hand-eye coordination.
