Abstract：
The purpose of this case series was to demonstrate the use of a magnesium membrane for repairing the perforated membrane in both direct and indirect approaches, as well as its application in instances where there has been a tear of the Schneiderian membrane.
The case series included four individual cases, each demonstrating the application of a magnesium membrane followed by bone augmentation using a mixture of xenograft and allograft material in the sinus cavity. In the first three cases, rupture of Schneiderian membrane occurred as a result of tooth extraction, positioning of the dental implant, or as a complication during the procedure. In the fourth case, Schneiderian membrane was perforated as a result of the need to aspirate a polyp in the maxillary sinus. In case one, 10 mm of newly formed bone is visible four months after graft placement. Other cases showed between 15 and 20 mm of newly formed alveolar bone. No residual magnesium membrane was seen on clinical inspection. The vertical and horizontal augmentations proved stable and the dental implants were placed in the previously grafted sites.
Within the limitations of this case series, postoperative clinical examination, and panoramic and CBCT images demonstrated that resorbable magnesium membrane is a viable material for sinus lift and Schneiderian membrane repair. The case series showed successful healing and formation of new alveolar bone with separation of the oral cavity and maxillary sinus in four patients.

摘要：
背景：本案例系列的目的是证明在直接和间接方法中使用镁膜修复穿孔膜，以及它在施耐德膜撕裂的情况下的应用。
方法：病例系列包括4例单独病例，每个都证明了镁膜的应用，然后在窦腔中使用异种移植和同种异体移植材料的混合物进行骨增强。在前三种情况下，Schneiderian膜破裂是拔牙的结果，牙种植体的定位，或者作为手术过程中的并发症。在第四种情况下，由于需要在上颌窦中抽吸息肉，施耐德膜被穿孔。万一有,移植后4个月可见10mm新形成的骨。其他病例显示新形成的牙槽骨在15至20毫米之间。临床检查未见镁膜残留。垂直和水平增强被证明是稳定的，并且将牙科植入物放置在先前的移植部位。
结论：在本案例系列的限制范围内，术后临床检查,全景和CBCT图像表明，可吸收的镁膜是一种可行的材料，用于窦提升和施耐德膜修复。该病例系列显示，四名患者成功愈合并形成了新的牙槽骨，并分离了口腔和上颌窦。
