Title: Innovations by Werner H Moermann

Introduction

Werner H Moermann is a notable inventor based in Zurich, Switzerland. He has made significant contributions to the field of dental technology, holding a total of four patents. His work focuses on methods and apparatuses that enhance dental procedures, particularly in the areas of three-dimensional imaging and custom dental restorations.

Latest Patents

One of his latest patents is a method and apparatus for three-dimensional registration and display. This innovative method allows dentists to record the shape of teeth prepared for repair in situ. During the search mode, a high-resolution grey scale image is presented on a monitor. The scan head is positioned over the prepared cavity, utilizing visual feedback. A trigger initiates actual 3D data acquisition, accomplished in a fraction of a second using an active triangulation principle. The result is stored in congruent memory banks as a 3D profile and a pseudoplastic grey scale image representing the back-scattered contrast. The pseudoplastic contrast image is displayed instantaneously on the monitor, allowing for a point-to-point relationship between the grey scale image and the 3D profile. This relationship enables the grey scale display to serve as a drawing plane for operator data verification and editing. The contour lines defining the desired restorative implant appear as an overlay to the grey scale image, while the actual positional values of points on the contour lines are stored in and retrieved from the 3D profile. The contrast-derived pseudoplastic image not only enhances intelligibility for the operator but also allows data processing algorithms to utilize both sets of data.

Another significant patent by Moermann is a method and apparatus for the custom shaping of dental inlays and onlays. This invention allows for machining a custom-shaped dental restorative part from a blank of dental material in a single operation. The workpiece is mounted on a support member that facilitates rotation and axial movement. A separating disk is used for most of the machining operation, with an optional burr tool for shaping more elaborate pieces. The disk and burr are powered by a closed-loop fluid supply arrangement, and a tool velocity sensing scheme is utilized for adaptive feed and compensation for tool wear. The entire machining mechanism and control circuitry are enclosed in a common cabinet, making it a mobile unit suitable for use in a dentist's office.
