Abstract

Functionalized ceramic dental crown was successfully fabricated through selective slurry extrusion (SSE) of solid freeform fabrication (also known as rapid prototyping) technologies. After being sintered, the decomposed nano-tourmaline powders were embedded in ZrO₂ matrix. The far infrared emission properties of the ceramic dental crown were improved due to the increased number of infrared active bonds coming from the tourmaline. This new dental restoration process presents potential to provide dental patients with functionalized artificial tooth, which benefits body health by means of emitting far infrared rays at ambient temperature.
