Abstract

Recently, treatment using a titanium implant has become a powerful tool for masticatory dysfunction, in which biocompatibility of titanium is improved by porous coating and alkali treatment. The present study aims to develop a dental implant with interconnected pores which enable tissue regeneration. The implant can be fabricated by a combined technology of rapid prototyping with spark plasma sintering (SPS) using titanium sheet made of a pure powder. The present study reports the evaluation of basic properties of the laminated titanium sheet that has been sintered by the SPS method, followed by the investigation of a technology for controlling internal cell structures. In particular, the use of NaCl powder is essential for retaining the shape of pores.
