Alveolar Ridge Splitting With Simvastatin/PRF Composite and Simultaneous Implant Placement (ARS-SIMV)
Alveolar Ridge Splitting Augmented With Simvastatin/Platelet-Rich Fibrin Composite With Simultaneous Implant Placement in Horizontal Ridge Augmentation: A Randomized Controlled Clinical Trial
연구 개요
상태
상세 설명
Horizontal alveolar ridge deficiency frequently complicates implant placement following tooth loss. Alveolar ridge splitting is a well-established technique for horizontal ridge augmentation that allows simultaneous implant placement when sufficient vertical bone height is available. However, the predictability of bone regeneration may be influenced by the grafting material used.
Platelet-rich fibrin (PRF) is an autologous biomaterial rich in platelets, leukocytes, and growth factors that may enhance angiogenesis, soft tissue healing, and bone regeneration. Simvastatin has also demonstrated osteogenic and angiogenic properties through stimulation of bone morphogenetic protein-2 (BMP-2) expression and inhibition of osteoclastic activity. Combining simvastatin with PRF may further improve regenerative outcomes.
This single-center, randomized controlled clinical trial included 21 participants with horizontal alveolar ridge deficiency requiring implant-supported rehabilitation. Participants were randomly allocated into three equal groups (n = 7 per group). Group I underwent alveolar ridge splitting with simultaneous implant placement and augmentation using a xenogeneic bone graft. Group II received a xenogeneic bone graft blended with PRF. Group III received a xenogeneic bone graft blended with a simvastatin/PRF composite.
Clinical and radiographic evaluations were performed to assess horizontal bone gain, vertical bone gain, bone density using cone-beam computed tomography (CBCT), and keratinized tissue width. The study aimed to determine whether the addition of PRF alone or in combination with simvastatin could improve regenerative outcomes compared with conventional xenogeneic bone grafting.
