Summary

Laser-modified titanium implants with micro- and nano-scale topography significantly enhanced bone formation and implant anchorage. This surface modification resulted in a 250% increase in removal torque after an 8-week healing period.

Re-osseointegration of titanium after experimental implant loosening.

Biomaterials science·2025

Area of Science:

  • Biomaterials Engineering
  • Orthopedic Research
  • Surface Science

Background:

  • Nanosized grooves on titanium implants enhance bone-implant anchorage.
  • Increased bone contact with the prosthesis improves osseointegration.

Purpose of the Study:

  • To evaluate the biomechanical and histological response to laser-modified titanium implants.
  • To compare laser-modified surfaces with traditional machined surfaces.
  • To investigate the effect of micro- and nano-scale topography on bone formation.

Main Methods:

  • Partly laser-modified and machined titanium implants were inserted into rabbit tibia and femur.
  • A healing period of 8 weeks was allowed.
  • Removal torque and histological analysis were performed to assess bone-implant contact and anchorage.

Main Results:

  • A 250% increase in removal torque was observed for laser-modified surfaces.
  • Significantly more bone-implant contact was found with laser-modified surfaces in the tibia.
  • Different fracture mechanisms were noted between the two surface types.

Conclusions:

  • Laser-induced micro- and nano-scale surface topography improves bone-implant interface anchorage.
  • Topological laser treatment enhances osseointegration through increased surface oxide and topography.
  • Surface modification is a promising strategy for improving dental and orthopedic implant success.
