| Outline of Final Research Achievements |
The communication between ephrin/Eph family was recently shown to be involved in cell differentiation under mechanical stress. To understand the roles of ephrinB2 and EphB4 in alveolar bone under initial mechanical stress of dental implant replacement, in vivo experiment was carried out. The mini-implant surface immobilised with ephrinB2-Fc recovered the suppression of Osterix. Taken together, the present results suggest that increased binding of ephrinB2 and EphB4 in osteoblast cells exposed to initial mechanical force, especially compressive force, may be involved in alveolar bone recovery.
