One of the most important medical applications of laser is low-level laser therapy (LLLT). In this method, laser radiation penetrates easily into the target tissue. The aim of this study was to investigate whether LLLT can reduce the side effects of advanced implant surgery. In this triple-blind clinical trial, 30 patients aged 25 to 65 years were selected for implant insertion and divided into two groups. In the laser group, immediately after the surgery, 72 hours and 1 week after the surgery, the surgical site was irradiated with an 830 nm laser. The dose required for the laser therapy was 5 J/cm . The degree of pain, facial swelling and wound healing were analyzed using statistical methods. Our results showed that at 12, 24, 48, and 72 hours after the surgery, the pain level was reduced in the laser group compared with the placebo group (<0.05). Swelling of the face was also significantly reduced 7 days after surgery in the laser group (<0.05). The investigation on the recovery conditions of the surgical site showed that on the 3rd, 7th and 14th days after the surgery, higher levels of wound healing have been achieved (<0.05). Our results suggest that laser, as a complementary therapy; can be used to reduce the severity and duration of pain. Also, laser can reduce facial swelling and accelerate wound healing.
激光最重要的医学应用之一是低强度激光疗法(LLLT)。在这种方法中,激光辐射很容易穿透到目标组织中。本研究的目的是调查低强度激光疗法是否能减少晚期种植手术的副作用。在这项三盲临床试验中,选取了30名年龄在25至65岁之间的患者进行种植体植入,并将其分为两组。在激光组中,术后立即、术后72小时和1周时,用830纳米的激光照射手术部位。激光治疗所需的剂量为5焦耳/平方厘米。使用统计方法分析疼痛程度、面部肿胀和伤口愈合情况。我们的结果表明,术后12、24、48和72小时,激光组的疼痛程度低于安慰剂组(<0.05)。激光组术后7天面部肿胀也明显减轻(<0.05)。对手术部位恢复情况的调查显示,术后第3、7和14天,伤口愈合程度更高(<0.05)。我们的结果表明,激光作为一种辅助疗法,可用于减轻疼痛的严重程度和持续时间。此外,激光还可减轻面部肿胀并加速伤口愈合。
