摘要

目的:本研究旨在比较有和没有磷酸钙涂层沉积的粗糙螺纹牙种植体，单独或联合低水平激光治疗砷化镓铝(LLLT)的体内成骨作用。材料与方法:研究四组:G1组:种植体;G2:种植体+ CaP涂层;G3:种植体+ LLLT;G4:种植体+ CaP涂层+ LLLT。种植体放置前后，在手术部位应用LLLT 7天。术前使用扫描电子显微镜和能量分散分光光度法进行地形表征。1周、2周和6周后测量骨-种植体接触(BIC)， 6周后测量反向扭矩。短期内，G2、G3、G4的BIC显著高于G1 (P < 0.05)，但6周时BIC无显著差异。然而，6周时G2和G4的去除扭矩测试值更高(P < 0.05)。结论:单独使用CaP涂层和使用LLLT均可诱导细胞刺激，改善短期愈合BIC，提高种植体固定水平，其成本低、效果好，值得临床应用。

CaP Coating and Low-Level Laser Therapy to Stimulate Early Bone Formation and Improve Fixation of Rough Threaded Implants.

Purpose: This study aimed to compare in vivo osteogenesis on rough threaded dental implants with and without calcium phosphate (CaP) coating deposition, alone or in association with low-level laser therapy (LLLT) by gallium aluminum arsenide.

Material and methods: Four groups were studied: G1: implant; G2: implant + CaP coating; G3: implant + LLLT; and G4: implant + CaP coating + LLLT. LLLT was applied for 7 days at the surgical site before and after placing the implant. Topographic characterization was performed before surgery using scanning electron microscopy and energy dispersion spectrophotometry. Bone-implant contact (BIC) was measured after 1, 2, and 6 weeks and reverse torque after 6 weeks. In short periods, G2, G3, and G4 showed significantly greater BIC than G1 (P < 0.05), but no difference in BIC was observed at 6 weeks. However, the values for the removal torque test at 6 weeks were higher in G2 and G4 (P < 0.05).

Conclusion: Both CaP coating alone and using LLLT induce cellular stimulation and improve BIC in short-term healing, resulting in higher implant fixation, and should be considered in clinical practice due to their low cost and high effectiveness.
