Description

一种用于口腔修复的陶瓷材料及其制备方法
技术领域
本发明属于陶瓷材料领域,具体涉及一种用于口腔修复的陶瓷材料及其制备方法。
背景技术
生物陶瓷是指具有特定的生物或生理功能的一类陶瓷材料。由于生物陶瓷材料具有良好的生物相容性、与生物组织的亲和性、耐腐蚀性、灭菌性以及物理化学稳定性等优点,在口腔领域占据越来越重要的地位。
通常,对牙齿病变严重需要拔除或天然牙齿缺损患者,进行口腔修复能够有效弥补牙齿功能。然而与天然牙齿相比,口腔修复用材料还存在一定的差别,会对使用者产生一定影响。对于口腔修复材料,材料的耐磨性是评价该修复材料好坏的重要指标。口腔修复材料常用的有陶瓷材料和树脂材料,其中树脂材料对天然牙齿的磨耗小,但是其耐磨性较差,也容易产生松动;陶瓷材料虽然具有良好的耐磨性、抗老化和耐腐蚀,但陶瓷材料本身硬且脆,容易出现破裂,因此有必要对口腔修复用陶瓷材料的性能进行改进优化,降低临床失败的风险,实现更佳的应用需求。

所述稀土氧化物包括Ta2O5、Sm2O3、Nd2O3,且对应的重量比为1:2:4。
本发明还提供一种用于口腔修复的陶瓷材料的制备方法,包括以下步骤:
(1)按照上述重量份数配料并混合;
(2)将混合后物料加入球磨罐湿法球磨8-20小时,经烘干、过150目筛后,装入石墨模具中在15-40MPa压力下模压成型得到坯体;
(3)将上述坯体在氮气气氛下热压烧结,随后自然冷却至室温即得所述用于口腔修复的陶瓷材料,其中热压烧结制度为:烧结温度为1270-1360℃,升温速度为5-12℃/min,烧结压力为15-45MPa,保温保压时间为45-90分钟。

由于采用了以上技术方案,本发明与现有技术相比具有如下有益效果:
本发明制备的用于口腔修复的陶瓷材料的维氏硬度超过21.4GPa,抗弯强度超过963.2MPa,断裂韧性高于16.3 MPa·m1/2,改善了传统的陶瓷材料本身脆而易脆断的不足,提高临床成功率,可作为口腔修复材料应用,具有广阔的应用前景。
