Purpose: This study reports four cases of vertical ridge augmentation using titanium reinforced
Polytetrafluoroethylene (TR-PTFE) membranes.
Material and Methods: Bone augmentation was performed using TR-PTFE membranes in four
patients with a vertical bony defect (mean 6.5 ± 0.58 mm) who was scheduled to receive dental
implants at the Department of Periodontology, Veterans Health Service Medical Center between
January and December 2016. Vertical bony defects were measured intraoperatively using a probe
and the exposure of membranes were assessed before and after suture removal and one month after
the surgery. The gained area from the reoperation as well as the need for additional bone grafting
during implant placement was assessed.
Results: The exposure was maintained without inflammation in one site. Placing an implant led to
an average of 5.25 ± 0.5 mm vertical augmentation, and none of the cases required additional bone
transplantation. A total of ten implants were installed in 4 cases. Over at least 1-year of follow-up, all
implants were functioned well.
Conclusion: In this case study, bone augmentation using TR-PTFE membranes. led to satisfactory
bone regeneration in defective areas with vertical bone resorption. In addition to a greater number
of cases, histological assessments should be performed in the future to further substantiate these
findings.
