It can be concluded that surface treatment with high power Nd laser pulses induces unique morphology with sizes in ten micron and 50 nanometer ranges and being topologically isomorf with the plane. It is clear that the 1-10 micrometer elements do not change strongly the osseintegration compared to the flat surface. On the other hand this surface in 20-50 micrometer range already enhance the osseointegration indicating a strong size dependens. The effect of the nanosized elements can be suggested also because their density has been increased with laser intensity. These two effects can not be separated with available data. It is evident that several questions in connection with laser treatment of surfaces such as first of all the time course of bone formation await further studies. Namely, if microgeometry plays a role in bone formation then the process of osseointegration should be also studied in conjunction with the comparisons of the various surfaces. It is hoped that our future studies can give responses to more questions and the results will contribute to the implementation of novel clinically successful techniques to improve the reliability of dental implants.
