Title: Automated measurement apparatus and method for quantifying dimensions of dental preparation
Inventor: MADDAHI YASER
IPC: A61C19/04
Filed: 2022-03-22
Abstract: An automated measurement apparatus has a tooth holder receiving a tooth and a measurement sensor that senses a measured distance to a corresponding surface portion of the tooth. Linear and rotational actuation assemblies support the measurement sensor and the tooth holder for translating and angular relative movement. A controller operates (i) the rotational actuation assembly to locate the tooth holder relative to the measurement sensor in one or more angular orientations and (ii) the linear actuation assembly to displace the measurement sensor through an array of measurement locations within a measurement plane to capture the measured distance at each array location at each angular orientation and thereby define a geometry of the tooth surfaces. The controller may define the geometry subsequent to a dental preparation alteration of the tooth and calculate an alteration metric representing one or more aspects of the defined geometry for comparison to a stored target metric.
