Laser-Based Ablation of Titanium-Graphite Composite for Dental Application

Area of Science:

• Biomaterials Engineering
• Materials Science
• Surface Engineering

Background:

• Modern dental implantology demands biocompatible materials with advanced mechanical and surface properties.
• Titanium-graphite composites offer potential for enhanced dental implant applications.

Purpose of the Study:

• To investigate the micromachining of a novel Ti-graphite composite using a nanosecond laser.
• To evaluate the effect of laser energy on the surface characteristics of the composite for dental implant applications.

Main Methods:

• Micromachining of Ti-graphite composite using a 1064 nm fibre nanosecond laser.
• Surface analysis via Scanning Electron Microscopy (SEM), Energy-Dispersive X-ray Spectroscopy (EDS), Confocal Laser-Scanning Microscopy (CLSM), and X-ray Diffraction (XRD).

Main Results:

• Laser energy density significantly altered surface morphology, roughness, elemental composition, and phase transformations.
• Specific energy levels promoted desirable surface features for potential implant integration.

Conclusions:

• The thermal energy delivered during laser micromachining critically influences the surface properties of Ti-graphite composites.
• Optimizing laser parameters is key to tailoring surface characteristics for improved dental implant performance.
