To promote a stable and functional direct connection between bone and implant, titanium implants can be coated with materials based on calcium phosphate ceramics such as hydroxyapatite (HAp)(Ca10(P04)6(OH)2).
The combination of these two materials gives mechanical strength and good osteointegration proprieties at the interface [5].
Materials and methods We used in this study bone material from one sheep with two implants, Ti-6Al-4V, (20 mm x 10 mm x 1.4 mm) inserted in its left and right tibia bones, the implant having one face coated, the other not.
The new bone material close to the interface may become unstable.

Test materials were collected from the test stand that had been 6 year old and had bloomed continuously for 4 years.
It began on 21, May, 2005 when stand was in bloom stage, that test materials were collected from the individuals with ARP-typical characteristic.

The requirements for structures vibration control can be divided into two categories, one is control the structure’s maxim displacement based on the available space and permitted maxim displacement, the other is control the structure’s maxim acceleration based on the serviceability of the structures and the strength of the materials.
