Abstract
Bone regeneration is currently considered to be most significant in implantology as regenerative therapy is directly involved and essential in dental prosthetics. The following factors, however, must be clarified before prosthetic treatment can be performed;
1. Necessity of bone regeneration and recovery with individual method
2. Change of regenerated bone
3. Analysis of dynamics which will affect bone resorption
Though these factors are important in prosthetics, dynamic analysis is not performed well even in the existing bone. Clinical follow-ups so far indicate that not only infection but also excessive loading influence most of the cases whose progress is not good. Moreover, there are many challenges to be solved for bone generated by regenerative therapy such as the timing of placing the implant, the timing of loading, conditions for loading and occlusal control.
