低功率激光对Beagle犬胫骨种植体周骨愈合的影响
Effect of low-level laser on the healing of bone tissues around the implant in tibia of Beagle dogs
摘要
Abstract
BACKGROUND: There is no definitive conclusion for the effect of low-level laser irradiation on the healing and osseointegration of bone tissues around the implant. OBJECTIVE: To investigate the effect of low-level He-Ne laser irradiation on the healing of bone tissues around the implant. METHODS: Thirty-six implants were randomly divided into three groups and planted into both sides of tibia of six Beagle dogs. The dogs were received low-level He-Ne laser irradiation for 1 and 2 weeks, but the dogs in the control group did not receive laser irradiation. Two dogs were randomly euthanized at 4, 8 and 12 weeks respectively. RESULTS AND CONCLUSION: Methylene blue-acid fuchsin staining showed that the healing degrees of the bone tissue around the implant were higher by laser irradiation. Bone histomorphome showed that the bone-implant contact ratio was gradually increased in a time-depend manner; at the same time points, the bone-implant contact ratio was highest in the 2-week irradiation group, and followed by 1-week irradiation group. The results revealed that the locally low-level He-Ne laser irradiation could promote the healing of bone tissue around the implant and increase the degree of osseointegration.关键词
