**3. Conclusions**

Within the exposed in this chapter, we can conclude that there is no implant with ideal characteristics, whether from a nano-, micro- or macrogeometric point of view. However, great advances in the knowledge of biological processes involving implant osseointegration have been discovered in recent years, which allowed a better understanding of these events. Undoubtedly, the new macrogeometric designs, based on the biological concept of minimizing surgical trauma, brought important advances in terms of accelerating the osseointegration process and, mainly, being able to benefit patients with systemic and/or local weaknesses that could negatively interfere in the process of implant osseointegration.
