Purpose: the aim of this work is to experimentally analyse the potential of the laser subtractive process as a new method for the creation of dental implants.

Design/methodology/approach: application of a subtractive process generating a high concentration of energy density, the heat focuses on an extremely small superficial portion. The material molecules, thanks to a vibrational motion, overheat till the cutting temperature.

Findings: the use of the laser technique allows for better and more precise results

Limitations: the groove shape obtained with the laser is less circular than that obtained with other methods

Practical implications: fast and precise process

Originality/value: this method offers a competitive advantage over conventional materials by means of the increasing efficiency of the applications for groove fabrication on biomaterials.
