The present report demonstrates a clinical approach to achieve vertical ridge augmentation around endosseous implants. Two implants were placed, leaving the threads exposed, in the atrophic mandibular right posterior quadrant of a male patient. Both implants were covered with a titanium-reinforced expanded polytetrafluoroethylene (e-PTFE) membrane. Second-stage surgery was performed 12 months after implant placement. Upon membrane removal, growth of mineralized tissue was observed around both implants, covering areas previously not covered by bone. Implants were then progressively loaded and restored. Titanium-reinforced e-PTFE membranes can be satisfactorily used for vertical augmentation of atrophic ridges.
本报告展示了一种在骨内种植体周围实现垂直牙槽嵴增高的临床方法。在一名男性患者萎缩的下颌右后象限植入了两枚种植体,使螺纹暴露在外。两枚种植体均覆盖有钛增强型膨体聚四氟乙烯(e-PTFE)膜。种植体植入12个月后进行二期手术。去除膜后,观察到两枚种植体周围均有矿化组织生长,覆盖了先前未被骨覆盖的区域。然后对种植体进行逐步加载和修复。钛增强型e-PTFE膜可令人满意地用于萎缩牙槽嵴的垂直增高。
