How Laser can help
Low Level Laser Therapy (LLLT) has been shown to accelerate bone healing, in both human and animal models, particularly in the early stages of repair when high cellular proliferation occurs. It is also demonstrated to improve the strength of bone tissue during the healing process.
Using mostly infra-red wavelengths to irradiate the bone, the therapy increases the activity in bone cells around the site of the repair. It prompts increased osteoblast proliferation, collagen deposition, and bone neo-formation when compared to non-irradiated bone.
Research has been most prolific in the dental field where laser phototherapy has demonstrated significantly improved results in both titanium and ceramic dental implant attachment and in combination with Guided Tissue Regeneration treatment.

Enhancement of bone formation in rat calvarial bone defects using low-level laser therapy
...The histomorphometrical evaluation suggested that the irradiated group had more bone-to-implant contact than the controls. The weight percentages of calcium and phosphorus were significantly higher in the irradiated group when compared to the controls, suggesting that bone maturation processed faster in irradiated group.
