To evaluate the effect of low-level laser therapy (LLLT) on bone healing in patients undergoing bilateral sinus lifting and simultaneous dental implant application.
Twelve patients with total/partial posterior maxillary edentulism who needed bilateral sinus bone augmentation were included in the study. Dental implants were inserted in the same session. LLLT (λ = 630-660 nm, 25 mW/cm, 6 min) was used for one operation side on the 1, 3, 5, and 7 days, whereas contralateral side served as control side. Preoperative and postoperative 1, 3, and 6 month orthopantomograms were obtained using the aluminum step-wedge technique. Optic density analyses were performed using a Cardinal Health Digital Densitometer (Fluke Biomedical 07-443) with 1 mm diameter. Digital densitometry results were obtained as the equivalent aluminum thickness for each radiograph. These data were used to evaluate the changes in optical bone density and to compare the treatment side with the control side for each patient.
The LLLT side showed better results than the control side according to the densitometry results. Increase in the bone density at all the postoperative intervals was statistically significant ( < 0.05).
LLLT enhances bone regeneration in sinus augmentation with simultaneous dental implant placement.
评估低强度激光疗法（LLLT）对接受双侧上颌窦提升并同期植入牙种植体患者骨愈合的影响。
本研究纳入12例需要双侧上颌窦骨增量的全口/部分上颌后牙缺失患者。在同一次手术中植入牙种植体。在第1、3、5和7天，对一侧手术部位使用LLLT（波长=630 - 660 nm，25 mW/cm，6分钟），而对侧作为对照。术前及术后1、3和6个月使用铝阶梯楔形技术获取全景片。使用直径为1 mm的Cardinal Health数字密度计（福禄克生物医学07 - 443）进行光密度分析。数字密度测量结果以每张X线片的等效铝厚度表示。这些数据用于评估骨光学密度的变化，并比较每位患者的治疗侧与对照侧。
根据密度测量结果，LLLT侧显示出比对照侧更好的结果。术后各时间段骨密度的增加具有统计学意义（<0.05）。
LLLT可增强上颌窦增量同期植入牙种植体时的骨再生。
