Background: Vertical bone resorption begins as soon as the tooth is extracted and, if not stopped, continues until the alveolar bone is completely atrophic. Various materials and techniques are used to rebalance the bone, which helps to restore the stable height of the alveolar bone. Three techniques are reviewed in this study: polytetrafluoroethylene membrane (PTFE), titanium mesh (Ti-mesh), and tenting pole. This systematic review aimed to evaluate the effectiveness of three different vertical augmentation techniques.
Methods: A systematic review of the literature was performed according to the PRISMA guidelines in search of clinical trials published between 2017 and 2022. Electronic literature searches were conducted independently by two authors.
Results: Studies indicate a vertical gain of alveolar bone from 2.36 ± 0.28 mm to 5.6 ± 2.6 mm, when using PTFE, and the mean vertical gain of alveolar bone was from 1.5 ± 1.6 mm to 6.36 mm when using Ti-mesh, and 1.72 ± 0.78 mm to 2.87 ± 0.79 mm bone gain using tenting pole technique.
Conclusion: Three used techniques: polytetrafluoroethylene membrane (PTFE), titanium mesh (Ti-mesh), and tenting pole showed acceptable results in the process of vertical augmentation. However, this study did not find robust evidence of which technique is the most effective.
