Dental implants, recognized for their enhanced functionality and aesthetic outcomes, are susceptible to peri-implant mucositis and subsequent peri-implantitis when oral hygiene is inadequate. Effective biofilm management is critical to prevent and manage these prevalent conditions and promote implant longevity. Materials with a two-dimensional (2D) structure have demonstrated robust antimicrobial properties. Among these, 2D magnesium phosphates have garnered significant attention due to their additional biocompatibility and osteoconductive properties. This case series explores the application of a thixotropic inorganic hydrogel, composed of 2D magnesium phosphate, in the surgical treatment of dental implant infections. The hydrogel was used for surgical dental implant decontamination in patients diagnosed with peri-implantitis characterized by inflammation in the peri-implant mucosa and subsequent progressive loss of supporting bone. The study encompassed eight cases with a history of peri-implantitis. Clinical measurements were recorded before and after treatment, including bleeding on probing, suppuration, and probing depth. Radiographic evaluations were conducted to assess the exposure of implant threads. The findings revealed a statistically significant decrease in probing depth, bleeding on probing, and the number of exposed implant threads following treatment with the magnesium phosphate hydrogel, though the exact role of the hydrogel in these improvements warrants further exploration.
牙种植体因其增强的功能和美学效果而受到认可，但当口腔卫生不足时，易发生种植体周围黏膜炎及随后的种植体周围炎。有效的生物膜管理对于预防和管理这些常见病症以及提高种植体使用寿命至关重要。具有二维（2D）结构的材料已显示出强大的抗菌性能。其中，二维磷酸镁因其额外的生物相容性和骨传导性能而备受关注。本病例系列探讨了一种由二维磷酸镁组成的触变无机水凝胶在牙种植体感染手术治疗中的应用。该水凝胶用于诊断为种植体周围炎的患者的手术牙种植体去污，其特征为种植体周围黏膜炎症及随后支持骨的逐渐丧失。该研究纳入了八例有种植体周围炎病史的病例。在治疗前后记录临床测量结果，包括探诊出血、化脓和探诊深度。进行影像学评估以评估种植体螺纹的暴露情况。结果显示，在用磷酸镁水凝胶治疗后，探诊深度、探诊出血和暴露的种植体螺纹数量在统计学上有显著减少，尽管水凝胶在这些改善中的确切作用值得进一步探索。
