一种可降解生物活性多孔陶瓷材料、制备方法及其应用
摘要：
本发明公开了一种可降解生物活性多孔陶瓷材料、制备方法及其应用。多孔陶瓷材料中包括钙镁硅酸盐和钙磷酸盐，其中钙镁硅酸盐重量百分数含量为40～98％，其中钙镁硅酸盐是镁质量百分含量为0.2～3.0％的硅灰石或假硅灰石，钙磷酸盐是磷酸三钙、磷灰石或者二者的复合物。制备是将合成的钙镁硅酸盐、钙磷酸盐粉体复合，再经增材制造和烧结处理而得。本发明中多孔陶瓷材料可以对整形外科、颌面外科、脑外科、口腔科、骨科或眼科中涉及的骨缺损进行骨诱导和传导再生修复，在大段肢体骨缺损骨重建中也具有应用价值。
摘要（英）：

The invention discloses a degradable bioactive porous ceramic material, a preparation method and an application of the degradable bioactive porous ceramic material. The porous ceramic material comprises calcium magnesium silicate and calcium phosphate, wherein the weight percent of calcium magnesium silicate is 40%-98%; calcium magnesium silicate is wollastonite or pseudowollastonite of which the magnesium weight percent is 0.2%-3.0%; and calcium phosphate is tertiary calcium phosphate, apatite or a compound of tertiary calcium phosphate and the apatite. The preparation method comprises the following steps: compounding synthetic calcium magnesium silicate and calcium phosphate powder; and carrying out material addition preparation and sintering to obtain the porous ceramic material. The porous ceramic material disclosed by the invention can carry out bone induction and conduction regeneration and repairing on related bone defects in a plastic surgery, a maxillofacial surgery, a thoracic surgery department, a department of stomatology, a department of orthopaedics or ophthalmology, and has application value in bone rebuilding of the bone defects of massive limbs.
