Two patients with apical lesions on maxillary central incisors showed large osseous defects of the residual ridge. E-PTFE membranes were used for ridge reconstruction, which allowed for the placement of implants of appropriate diameters. In the two cases described, the membranes were exposed and replaced. This technique facilitated atrophic ridge reconstruction in spite of premature membrane exposure.
两名上颌中切牙根尖病变患者的剩余牙槽嵴出现了大面积骨缺损。使用了e-PTFE膜进行牙槽嵴重建，这使得能够植入合适直径的种植体。在所描述的两例病例中，膜出现了暴露并进行了更换。尽管膜过早暴露，但该技术仍促进了萎缩性牙槽嵴的重建。
