Bio-ceramics such as alumina, calcium phosphate and zirconia have been employed in medical and dental industry due to their distinctive characteristics. Especially for the ceramic prostheses in dental applications, zirconia ceramics have been widely used since they have exhibited extraordinary performances in terms of the mechanical and biological properties. In this work, DLP(Digital Light Processing) technique was introduced to fabricate the dental crowns elaboratively using high solid loading slurries which maintain the stability of homogeneous composition. Due to the increasing aesthetic demands, 5Y-PSZ (5 mol% yttria partially stabilized zirconia) has been used to improve the transmittance for modifying natural teeth. The predetermined amounts of slurry were extruded through the nozzle and tape casting was followed by photocuring. After debinding and sintering procedure, dental crowns which exhibited excellent mechanical properties and aesthetics at the same time were fabricated precisely based DLP technique. |
