Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the study was to compare the change in augmentation thickness after guided bone regeneration (GBR) using bovine-derived xenograft in combination with or without injectable platelet-rich fibrin (i-PRF).

This randomized-controlled clinical trial was conducted on patients with horizontal bone deficiency in the posterior regions of mandible. After implant placement, GBR procedures were randomly performed using i-PRF enriched bovine-derived xenograft (test group) or bovine derived xenograft alone (control group). Cone-beam computed tomography was taken at the implant sites immediately, and 6 months after surgery for assess the change in augmentation thickness as the primary outcome of the study. The secondary outcomes included marginal bone level and implant survival rate.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study was conducted on patients who had partially edentulism with horizontal deficiency of the alveolar bone in the posterior regions of mandible.

All patients were informed about treatment protocol of the study and also, the risks and benefits associated with participation. Each patient provided written informed consent prior to enrollment.

Randomization was performed after the dental implant surgeries and the patients were randomly assigned to one of the study groups:

Test group included 22 patients treated with GBR using i-PRF-enriched bovine-derived xenograft + resorbable membrane Control group included 22 patients treated with GBR using bovine-derived xenograft + resorbable membrane All patients underwent two-stage surgical protocol that performed by the same experienced surgeon. Following implant placement, i-PRF-enriched bovine-derived xenograft for the test group and bovine-derived xenograft alone for the control group was carefully positioned with light compression around the implants. Finally, the resorbable membrane was placed to cover the augmented area.

As the second stage of surgery, healing caps were placed and the implant-supported fixed prosthesis were completed in approximately one to two months.
