Abstract: A method for manufacturing a mouthpiece is disclosed. The method includes receiving a digital representation of a teeth model, creating a shell model overlying an outer surface of the teeth model, identifying a target position on the shell model where a sensor of the mouthpiece is to be placed, and generating a modified teeth model comprising a dimple underneath the shell model at the target position.

Abstract: A method for making a case insert for a mouthpiece having an embedded circuit board is disclosed. The method includes receiving a digital representation of a teeth model, creating a first shell model based at least in part on the digital representation of the teeth model, placing one or more objects modeling the embedded circuit board on the first shell model, creating a second shell model covering the first shell model and the one or more objects, and creating a case insert model based at least in part on the second shell model.

Abstract: A physical preform suitable for a screw retained dental restoration (“SRR”) includes a sintered preform and an insert receiving region within at least a portion of the sintered preform. A computer-implemented method of providing a screw retained dental restoration includes receiving a virtual restoration mode and generating one or more virtual spiral toolpaths corresponding to a virtual restoration shape of the virtual restoration model. A computer-implemented method of correcting preform placement during milling includes probing one or more surface points of a preform mounted to a milling machine using a grinding bur of the milling machine and determining one or more preform alignment parameters based on a distance traveled by the grinding bur to the one or more surface points.
