2-dimentional shape analysis was studied for the purpouse of clinical use. The resarched materials were dental implants made by Zirconia ceramics with the use of the finite element method. The dental implant was designed blade type looked like arch-shaped in lower surface. It was supposed six types for supporting condition.
As a result of analysis for each supporting condition, three weak points of its intensity were found,they were;arch-shaped area of under surface, both endlooked like wing and around the central vent.
Then, they were reformed flat surface only in its under portion from arch-shape. In consequence, good results were obtained, unless stress concentration and ditsurbance of stress distribution.
