Latest Patents

One of Liu's latest patents is for a denture that includes a tooth and denture base. The tooth features an interpenetrating polymer network polymeric matrix and at least 0.1 percent by weight of self-lubricating particles, effectively bonded to and distributed in the polymeric matrix. This denture boasts a bond strength between the tooth and the denture base of at least 4,480 psi. Another notable patent is a method for making a tooth mold. This method involves scanning the surface of a model of a tooth to obtain data on the three-dimensional surface locations, processing this data in a CAD/CAM computer, and using it to fabricate a tooth mold. The scanning step utilizes radiant energy from a laser beam, which is translated into electronic signals and digitized into data. The processing step includes creating a three-dimensional surface pattern and evaluating it against known geometric values. Finally, the fabricating step directs a machine to mill and finish-polish the tooth mold.
