: A rigid, resorbable magnesium membrane was recently developed, combining the advantages of resorbable and non-resorbable membranes. Our aim was to describe the application of this membrane for guided bone regeneration (GBR). : This case report described the treatment and 3D evaluation of two cases utilizing a resorbable magnesium barrier membrane. In Case #1, GBR was performed with a bilayer tunnel flap. The magnesium barrier was placed fixed subperiosteally through remote vertical incisions. In Case #2, GBR was performed using a split-thickness flap design. Volumetric and linear hard tissue alterations were assessed by 3D cone-beam computed tomography subtraction analysis, as well as with conventional intraoral radiography. : Case #1 showed a volumetric hard tissue gain of 0.12 cm, whereas Case #2 presented a 0.36 cm hard tissue gain. No marginal peri-implant hard tissue loss could be detected at the two-year follow-up. : The application of conventional resorbable collagen membranes would be difficult in either of the cases presented. However, the rigid structure of the magnesium membrane allowed for the limitations of conventional resorbable membranes to be overcome.
: 最近开发了一种刚性可吸收的镁膜,结合了可吸收和不可吸收膜的优点。我们的目的是描述这种膜在引导骨再生(GBR)中的应用。 : 本病例报告描述了使用可吸收镁屏障膜治疗和 3D 评估的两例病例。在病例 1 中,通过双层隧道瓣进行 GBR。镁屏障通过远程垂直切口固定在骨膜下。在病例 2 中,使用了分层瓣设计进行 GBR。通过 3D 锥形束 CT 减影分析以及常规口腔内放射照相评估体积和线性硬组织变化。 : 病例 1 显示体积硬组织增加了 0.12cm,而病例 2 显示硬组织增加了 0.36cm。在两年的随访中,未检测到种植体周围边缘硬组织的丧失。 : 在报告的两种情况下,应用传统的可吸收胶原膜都将很困难。然而,镁膜的刚性结构克服了传统可吸收膜的局限性。
