Vertical ridge augmentation (VRA) using titanium-reinforced dense polytetrafluorethylene (d-PTFE) membranes has been associated with promising clinical outcomes. This retrospective multicenter case series was prepared for the purpose of identifying the elements that contribute to the predictability of this surgical technique. VRA procedures were carried out in 35 patients (13 male and 22 female) with an age range of 43 to 76 years. The average bone gain was 5.44 mm. In the Kaplan-Meier estimates of cumulative survival calculated at 15 months, membrane exposure (P = .045) was a predictor for VRA.
使用钛增强致密聚四氟乙烯（d-PTFE）膜进行垂直牙槽嵴增高术（VRA）已取得了令人满意的临床效果。本回顾性多中心病例系列旨在确定有助于该手术技术可预测性的因素。对35例患者（13例男性和22例女性）进行了VRA手术，年龄范围为43至76岁。平均骨增量为5.44毫米。在15个月时计算的Kaplan-Meier累积生存率估计中，膜暴露（P = .045）是VRA的一个预测因素。
