Post-extraction bone resorption may affect the outcome of ensuing restorations.
This study aimed to evaluate a comprehensive laser post-extraction protocol by comparing resulting alveolar bone regeneration with that obtained after standard extraction procedure.
About 53 simple extractions were randomized to either laser or control group. In the laser group, erbium (Er:YAG; 2940 nm) and neodymium (Nd:YAG; 1064 nm) lasers were used for degranulation, disinfection, de-epithelialization of the surrounding gingiva, clot stabilization, and photobiomodulation. The primary outcome measure was change in bone density in the extraction area between day 1 and 4 months after extraction. Patients were monitored for potential side effects.
Increase in bone density at the follow-up CBCT was significantly higher in laser than in control group (p < 0.001). No post-operative pain, bleeding, or swelling was present in the laser group. In the control group, one patient had bleeding 3-5 days after extraction, two patients had swelling and three patients reported post-operative pain rated 3-5 on a 0-10 pain scale up to 3 days after extraction.
The proposed laser post-extraction procedure is a safe and effective method to improve post-extraction bone healing.
拔牙后骨吸收可能会影响后续修复的效果。
本研究旨在通过比较标准拔牙术后和综合激光拔牙术后的牙槽骨再生情况，评估一种综合激光拔牙后处理方案。
大约 53 例简单拔牙被随机分为激光组或对照组。在激光组中，使用铒（Er:YAG；2940nm）和钕（Nd:YAG；1064nm）激光进行脱颗粒、消毒、周围牙龈去上皮化、血凝块稳定和光生物调节。主要观察指标为拔牙后 1 天至 4 个月拔牙区骨密度的变化。监测患者的潜在不良反应。
激光组在随访 CBCT 中骨密度的增加明显高于对照组（p<0.001）。激光组无术后疼痛、出血或肿胀。对照组中，1 例患者在拔牙后 3-5 天出血，2 例患者肿胀，3 例患者在拔牙后 3 天内报告术后疼痛评分 3-5（0-10 疼痛评分）。
所提出的激光拔牙后处理方法是一种安全有效的改善拔牙后骨愈合的方法。
