利用光生物调节结合生物材料移植评估磨牙拔除后的骨保存
2023年12月13日 更新者:Sandra Kalil Bussadori、University of Nove de Julho
使用光生物调节结合支架生物材料移植来评估早期磨牙拔除后牙槽骨的保存:临床、随机、三盲研究。
牙齿缺失是一个全球性的公共卫生问题,是咬合和口腔骨畸形的主要原因。
牙齿缺失最多的牙齿可以被确定为第一磨牙。
拔牙后立即将骨移植物添加到牙槽中,可以防止牙齿缺失部位的骨骼萎缩和畸形。
光生物调节加速骨骼愈合;刺激血液流动;激活成骨细胞,降低破骨细胞活性并改善生物材料与骨组织的整合。
该研究的目的是制定一项方案,用于管理和保存 18 岁以上患者第一和/或第二恒磨牙缺失后的牙槽骨,并提供与 808 nm 红外线治疗相关或不相关的拔牙指征激光。 。
材料和方法:60 名 18 岁以上的患者将被随机分为 4 组,n=15:Exo(拔牙)、Exo+Laser(拔牙和激光治疗)、Exo+Biomat(生物材料移植拔牙)、 Exo+Biomat+Laser(生物材料提取和移植以及激光治疗)。
选择的生物材料将是 Plenum® OSShp 和 Plenum® Guide(巴西),在拔牙后立即添加到牙槽窝中,将接收激光的组(λ = 808 nm,功率 = 100 mW,辐射能量 3J 每点分 3 次)颊、咬合点和舌/腭点),将在手术期间和手术后 10 天接受照射,在 Exo 和 Exo+Biomat 组中,将使用类似的激光设备,但不会发射辐射,应用激光的操作者和患者将不知道所使用的设备,并且患者将不知道他们是否收到了生物材料。
分析:术前和术后4个月进行计算机断层扫描和口内扫描;通过测量每组牙槽窝的高度和宽度以及骨小梁和缺失元件侧面牙齿的齿间空间来评估骨量。
统计分析将分别使用 Shapiro-Wilks 检验、Student's t 检验或 Wilcoxon-Mann-Whitney 检验对参数和非参数数据进行双尾检验,采用的显着性水平为 α = 0.05。

详细说明
牙齿缺失是一个全球性的公共卫生问题,是咬合和口腔骨畸形的主要原因。
牙齿缺失最多的牙齿可以被确定为第一磨牙。
拔牙后立即将骨移植物添加到牙槽中,可以防止牙齿脱落部位的骨骼萎缩和畸形。
光生物调节加速骨骼愈合;刺激血液流动;激活成骨细胞,降低破骨细胞活性并改善生物材料与骨组织的整合。
该研究的目的是制定一项方案,用于管理和保存 18 岁及以上患者第一和/或第二恒磨牙缺失后的牙槽骨,并提供与 808 nm 红外治疗相关或不相关的拔牙指征。

生物材料)、Exo+Biomat+Laser(生物材料的提取和移植以及激光治疗)。
选择的生物材料将是 Plenum® OSShp 和 Plenum® Guide(巴西),在拔牙后立即添加到牙槽窝中,将接收激光的组(λ = 808 nm,功率 = 100 mW,辐射能量 3J 每点分 3 次)颊点、咬合点和舌/腭点),将在手术期间和手术后 10 天接受照射,在 Exo 和 Exo+Biomat 组中,将使用类似的激光设备,但不会发射辐射,应用激光的操作者和患者将不了解所使用的设备,也不知道他们是否收到了生物材料。
分析:术前和术后 4 个月进行计算机断层扫描;通过测量每组牙槽窝的高度和宽度以及缺失元件侧面的骨小梁和牙齿齿间间隙来评估骨体积,并通过分形分析评估所形成骨的体积和密度。
统计分析将分别使用Shapiro-Wilks检验、Student's t检验或Wilcoxon-Mann-Whitney检验对参数和非参数数据进行双尾检验,采用的显着性水平为α = 0.05。

在正径向切割中,牙槽的界限将根据牙齿的顶点到骨嵴的最大高度来划定。
在最中心位置,进行垂直测量,并根据测量的垂直测量相互成比例地进行3个颊舌切口;在每个心尖、中部和颈部三分之一处,将测量牙槽的水平尺寸。
对于分形分析,将划定包含牙槽的感兴趣区域,并使用公共领域的 Image J 程序来计算分形维数。
