Application of Laser-Induced Bone Therapy by Carbon Dioxide Laser Irradiation in Implant Therapy

الملخص EN

This study evaluated the application of laser-induced bone therapy (LIBT) to reduce implant healing time in rat tibia.

Twenty 10-week-old female Sprague-Dawlay rats were used.

The rats received laser irradiation (laser group) or sham operation (control group) on either side of the tibia.

Five days after invasion, titanium implants were inserted in proximal tibia.

Five, 10, and 20 days after implant placement, tibiae were collected.

After taking micro-CT and performing a torque test, the tibiae were decalcified and 8-μm-thick sections were prepared.

Specimens were stained with hematoxylin and eosin.

Results.

Micro-CT images, removal torque values, and histomorphometric analysis data demonstrated a significantly accelerated bone formation in the laser group earlier in the healing process.

Conclusion.

The use of laser irradiation was effective in promoting bone formation and acquiring osseointegration of titanium implants inserted in rat tibia.

LIBT may be suitable for use in implant therapy.
