The marginal bone loss of implants with laser treated surface was investigated after six weeks of loading after implant installation to the mandible molar area.
A total of 23 implants were placed in the edentulous molar area of the mandible: 13 implants were immediately loaded and 10 implants were early loaded. The implants used were made of titanium grade 23, screw shaped, 4.2 mm in diameter, and 10 mm in length. Patients were evaluated with resonance frequency analysis at implant fixture installation and 1, 2 (final prosthesis installation), 3, 5, 8, and 14 months later. X-rays were taken at 2 months after fixture installation and 1, 2, 3 years after to measure the marginal bone loss.
The mean ISQ value measured at the implant installation was over 70 at all-time points. The average of marginal bone loss was average 0.33 mm.
Immediate implant loading for laser treated implants would be possible.

  • Fig. 1 Mean and SD of ISQ values measured from implant fixture installation to 14 months after surgery. FI: at implant installation, 1M: 1 month later, 2M: 2 months later (final prosthesis placement), 3M: 3 months later, 5M: 5 months later, 8M: 8 months later, 14M: 14 months later. Success criterion was a value greater than or equal to 70 (red-line).

  • Fig. 2 Mean and SD of marginal bone loss measured from implant fixture installation to 36 months after surgery. 2M: 2 months later (final prosthesis placement), 14M: 14 months later, 24M: 24 months later, 36M: 36 months later. Cut-off value was 1.5 mm (red-line).
