Abstract

Background: Photobiomodulation (PBM) may be prescribed after dental surgery to accelerate tissue healing and improve implant stability. The objective of this study is to evaluate the efficiency of LED-PBM on the dental implant osseointegration.

Methods: A total of 48 implants (Kontact^TM) were inserted in 8 Yucatan minipigs (6 implants per minipig) divided into 2 groups (test and control). The test group received LED-PBM with a total energy of 124.2 J/cm² delivered over 4 sessions (at day0, day+8, day+15 and day+28) lasting 12 minutes each. At day+28, all animals were sacrificed, and their mandibles removed to perform histologic and histomorphometric analysis. Implant osseointegration was evaluated using the computation of bone/implant contact (BIC) index and bone surface/total surface (BS/ TS) ratio. The groups were compared using Student's unpaired t test.

Results: BIC index and BS/TS ratio were significantly higher within the test group as compared to the control group (P<0.01). Histologic observations on bone tissues demonstrated that LED-PBM may improve and accelerate dental implant osseointegration: 25% of dental implants analyzed within the test group were completely osseointegrated, versus 12.5% within the control group.

Conclusion: This experimental study indicates that LED-PBM contributes to enhancing implant treatment outcomes.

LED光生物调节对牙种植体骨整合影响的体内研究。

背景:光生物调节(PBM)可以在牙科手术后处方，以加速组织愈合和提高种植体的稳定性。本研究的目的是评估LED-PBM对种植体骨整合的效果。方法:将48颗种植体(KontactTM)植入8头尤卡坦小型猪(每头小型猪6颗)，分为2组(试验组和对照组)。试验组接受总能量为124.2 J/cm2的LED-PBM，分4次(第0天、第8天、第15天和第28天)，每次持续12分钟。第28天处死所有动物，取下颌骨进行组织学和组织形态学分析。通过计算骨/种植体接触指数(BIC)和骨面/总面(BS/ TS)比评估种植体骨整合情况。组间比较采用Student’s unpaired t检验。结果:试验组的BIC指数和BS/TS比值明显高于对照组(p结论:本实验研究表明LED-PBM有助于提高种植体治疗效果。
