| Outline of Final Research Achievements |
This time we would like to focus on how the superstructure design of implant-supported fixed prosthesis and the number of implant affects mechanical behavior.
The patient is 67-year-old woman, and three implants were installed between second premolar to second molar region in the left side of mandible. 3 Types of superstructure design were modeld with biological loading data.In summary,1) Decrease of the number of implants supporting FPDs doesn’t always cause an increase of stress and displacement.2) Cantilever bridge design causes an increase of stress and displacement.3) The stress and displacement were increased remarkably during function. Finally in conclusion, from this study, the design of cantilever bridge may cause an increase of stress in peri-implant bone and displacement of superstructure in implant-supported FPDs.
