Bone substitutes and barrier membranes are widely used in dental regeneration procedures. New materials are constantly being developed to provide the most optimal surgical outcomes. One of these developments is the addition of hyaluronate (HA) to the bovine bone graft, which has beneficial wound healing and handling properties. However, an acidic environment that is potentially produced by the HA is known to increase the degradation of magnesium metal. The aim of this study was to evaluate the potential risk for the addition of HA to the bovine bone graft on the degradation rate and hence the efficacy of a new biodegradable magnesium metal GBR membrane. pH and conductivity measurements were made in vitro for samples placed in phosphate-buffered solutions. These in vitro tests showed that the combination of the bovine graft with HA resulted in an alkaline environment for the concentrations that were used. The combination was also tested in a clinical setting. The use of the magnesium metal membrane in combination with the tested grafting materials achieved successful treatment in these patients and no adverse effects were observed in vivo for regenerative treatments with or without HA. Magnesium based biodegradable GBR membranes can be safely used in combination with bovine graft with or without hyaluronate.
骨替代物和屏障膜在牙再生手术中被广泛应用。新型材料不断涌现,以实现最理想的手术效果。其中一项进展是在牛骨移植材料中添加透明质酸盐(HA),其具有促进伤口愈合和便于操作的特性。然而,已知HA可能产生的酸性环境会加速镁金属的降解。本研究旨在评估在牛骨移植材料中添加HA对降解速率的潜在风险,进而评估一种新型可生物降解镁金属引导骨再生(GBR)膜的有效性。对置于磷酸盐缓冲溶液中的样本进行了体外pH值和电导率测量。这些体外测试表明,在所使用的浓度下,牛骨移植材料与HA的组合会产生碱性环境。该组合也在临床环境中进行了测试。镁金属膜与受试移植材料联合使用,在这些患者中实现了成功治疗,无论有无HA,在再生治疗中均未观察到体内不良反应。基于镁的可生物降解GBR膜可安全地与含或不含透明质酸盐的牛骨移植材料联合使用。
