The gingival phenotype refers to the gingival thickness (GT) and the width of the keratinized tissue (KTW). A gingival thickness of ≤1 mm is classified as a thin phenotype, whereas a thickness \\>1 mm is considered a thick phenotype. Thin gingival biotypes tend to show more pronounced responses to inflammation, restorations, trauma, and parafunctional habits. Various methods are used to assess gingival thickness, including transgingival probing (TP), ultrasonic measurements, cone-beam computed tomography (CBCT) scans, visual assessment, and colored biotype probes (CBP). Periodontal plastic procedures performed using autogenous grafts such as connective tissue grafts (CTG) and free gingival grafts (FGG), or biomaterials such as acellular dermal matrices (ADM) and collagen matrices (CM), are known to significantly increase GT and the amount of keratinized tissue. However, creating a second surgical site in the oral cavity during these procedures may compromise patient comfort, prompting researchers to explore alternative methods. Additionally, the effectiveness of synthetic biomaterials has been found to be lower than that of autogenous grafts.\n\nPlatelet-rich concentrates have been used as a minimally invasive procedure for the past thirty years, showing a high capacity to release growth factors that support tissue regeneration. While platelet-rich plasma (PRP), as the first-generation platelet concentrate, is widely used, platelet-rich fibrin (PRF) has been increasingly applied across various fields of medicine and dentistry due to its ability to release more growth factors over a longer period, resulting in better clinical outcomes. PRF is a highly biocompatible material composed of autologous cells and growth factors entrapped in a fibrin matrix, and has been shown to degrade more slowly over time compared to conventional PRP. One of the main reported disadvantages of PRF (and especially PRP) is its relatively rapid resorption, typically within 2-3 weeks. Biofiller is an autologous material derived from the patient's own blood and includes platelet-poor plasma (PPP) and concentrated platelet-rich fibrin (PRF). The PPP component is heated to become enriched with albumin, thereby prolonging its resorption time. The PRF portion contains autologous cells and growth factors. However, conventional PRF is typically resorbed within 2-3 weeks, limiting its clinical application. Recent studies have shown that the resorption time of biofiller-a combination of PPP and PRF-can exceed 4 months.\n\nThe aim of this study is to compare the effectiveness of biofiller with connective tissue graft in increasing gingival thickness in patients with a thin gingival phenotype. A total of 34 patients (17 patients in each group) will be enrolled. Tunnel surgery will be performed to all participants and test group will receive biofiller only once. Control group will receive connective tissue surgery. Clinical parameters obtained from our patients at baseline and at follow-up visits at 1, 3, and 6 months - including gingival thickness (GT), keratinized tissue width (KTW), and soft tissue measurements assessed via intraoral scanners - will be compared.",[83,84,85],"Gingival Recession","Gingival Diseases","Gingival Inflammation",[87,88,29],"biofiller","gingival phenotype modification","2025-08-06",{"date":91,"type":92},"2025-08-12","ACTUAL",{"date":94,"type":92},"2025-07-30",{"date":96,"type":77},"2026-05-01",{"name":5,"class":6},1]
