Abstract:
Objective: Guided bone regeneration (GBR) for vertical bone augmention is an easy-to-implement approach and has a good prognosis. However, there are many different procedures that lead to different clinical outcomes. The use of platelet-rich fibrin (PRF) can improve outcomes in regenerative treatments. Therefore, this study aimed to evaluate the effectiveness of vertical bone grafting by guided bone reconstruction with titanium-reinforced PTFE membrane combined with PRF. Materials and Methods: Nine patients who come to the Department of Odonto-Stomatology, University of Medicine and Pharmacy, Ho Chi Minh City, have a need for implant treatment and have mild to moderate vertical bone deficiency. Patients are treated with bone grafting by GBR technique: using a mixture of bone grafts including autogenous bone and deproteinized bovine bone (Geistlich Bio-Oss) at a ratio of 1:1, mixed with injectable form PRF in the form of sticky bone. The vertical bone defects were protected by a titanium-reinforced d-PTFE membrane and covered by an A-PRF+ membrane. The bone gain was measured using a cone-beam computed tomography at baseline and after a period of 8 months. Results: Analyzing the research results on 9 patients, 15 research units corresponding to 15 bone grafting sites, the GBR procedures an increase in bone height (p 〈 0,05) after treatment. In the two-staged approach, the vertical bone gain was 3.97 ± 0.92 mm; in the group of simultaneous one-staged procedure, the vertical bone gain was 3.89 ± 1.13 mm. In general, the bone height of the study sample achieved an average of 94.16 ± 10.7% compared to the ideal bone height. Conclusion: GBR technique using a mixture of particulate autogenous bone and xenogenous bone and PRF is effective for vertical bone augmentation in maxillary and mandibular regions, ensuring favorable bone morphology, permitting sufficient bone gain to future implant placement and prosthetics.
