Treatment for receding gums is always a challenging task for a periodontist. To fulfill this, many surgical techniques such as free gingival grafts, connective tissue grafts, pedicle flaps, and lateral sliding flaps have been used. For better prevention of relapse of these procedures and to improve the gingival biotype, various biomaterials such as platelet-rich fibrin, collagen matrix, and amnion chorion membranes have been additionally utilized. Due to advancements in preparation of platelet concentrates titanium platelet-rich fibrin, a third-generation platelet concentrate was introduced. Unlike other biomaterials, it has thicker fibrin meshwork with greater cellular entrapment and thicker membrane. Present case reports depict the usage of titanium platelet-rich fibrin as a biomaterial along with coronally advanced flap in the treatment of millers Class-I gingival recessions. Patients were followed up to 6 months after performing recession coverage treatments.
对牙周病医生来说,治疗牙龈退缩始终是一项具有挑战性的任务。为了完成这项任务,人们采用了许多外科技术,如游离龈瓣移植术、结缔组织移植术、蒂瓣手术和侧向滑行瓣手术。为了更好地预防这些手术的复发并改善牙龈生物型,人们还额外使用了各种生物材料,如富血小板纤维蛋白、胶原基质和羊膜绒毛膜。由于血小板浓缩物制备技术的进步,第三代血小板浓缩物——富血小板纤维蛋白钛被引入。与其他生物材料不同,它具有更厚的纤维蛋白网络,能截留更多细胞,且膜更厚。目前的病例报告描述了富血小板纤维蛋白钛作为一种生物材料与冠向推进瓣联合用于治疗米勒I类牙龈退缩的情况。在进行牙龈退缩覆盖治疗后,对患者进行了长达6个月的随访。
