The application of Moire topography to removable prosthodontics

The study was designed to assess the dental research potential of moire topography--the use of geometrically regular light patterns for measuring three-dimensional objects. One hundred thirty-nine maxillary edentulous casts and 20 mounted cast pairs were evaluated. Results demonstrated that the moire topography techniques can be used to quantitatively evaluate edentulous arch forms, compare edentulous ridge forms and surfaces, determine the amount of overlap of mounted maxillary and mandibular casts, and confirm prime areas for positioning posterior teeth.
