The effect of post‐extraction socket preservation laser treatment on bone density 4 months after extraction: Randomized controlled trial

BACKGROUND: Post‐extraction bone resorption may affect the outcome of ensuing restorations. PURPOSE: This study aimed to evaluate a comprehensive laser post‐extraction protocol by comparing resulting alveolar bone regeneration with that obtained after standard extraction procedure. MATERIALS AND METHODS: 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. RESULTS: 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. CONCLUSIONS: The proposed laser post‐extraction procedure is a safe and effective method to improve post‐extraction bone healing.
