The purpose of the present study is to evaluate the clinical usage of zirconia ceramics dental implant,and to evaluate the mechanical strength of zirconia ceramics implant prior to its clinical application. It was originally designed type A as a mold of blade,and it was analysed by finite element method. Then developed type B and consequently type C which showed favorable property compareing proceding type. Characteristic shape of type C having two vent located underneath the two heads and concaved contour of wing. Beside, compression and bending test made on this type C dental implant showed most desirable result. Histological examination also showed that the dental implant was attached with bone,partially surrounded with thin fibrous connective tissues without any sign of bone resorption. The result obtained in the present study is that the type C dental implant is positively suggested and concerned application for clinical use.
