Abstract

本发明公开了一种提高牙种植体表面硬度和强度的方法，该方法可应用于提高成品牙种植体的表面硬度和强度，方法如下：首先对牙种植体进行表面清洁，以去除其表层金属碎屑、杂质、油脂等，再将牙种植体置入重铬酸钾与水的质量比为1:100的溶液中，加热该溶液至沸腾，并使牙种植体在沸腾的溶液中连续处理15分钟，处理完毕的牙种植体用无水乙醇清洗，自然晾干。

Description

一种提高牙种植体表面硬度和强度的方法
技术领域
本发明涉及一种提高牙种植体表面硬度和强度的方法。
背景技术
强度是牙种植体产品的重要指标，表面硬度与强度高的牙种植体植入患者口腔后稳定性更好，同时能够对抗更大的咬合力而不发生形变。本发明利用强氧化剂重铬酸钾溶液在100℃左右对牙种植体表面进行温和氧化，使氧元素逐渐渗透并形成固溶层，提高了牙种植体的表面硬度和整体强度。
发明内容
首先对牙种植体进行表面清洁，以去除其表层金属碎屑、杂质、油脂等，再将牙种植体置入重铬酸钾与水的质量比为1:100的溶液中，加热该溶液至沸腾，并使牙种植体在沸腾的溶液中连续处理15分钟，在扩散的作用下，氧元素逐渐渗入牙种植体，并形成固溶层，可使牙种植体的表面硬度和整体强度得以提高。
具体实施方式
实施例1
Ti6Al4V合金牙种植体处理
首先对Ti6Al4V牙种植体进行表面清洁，以去除其表层金属碎屑、杂质、油脂等，再将牙种植体置入重铬酸钾与水的质量比为1:100的溶液中，加热该溶液至沸腾，使牙种植体在沸腾的溶液中处理15分钟，处理完毕的牙种植体用无水乙醇清洗，自然晾干。牙种植体的表面硬度和整体强度得以提高。
实施例2
Ti6Al7Nb合金牙种植体处理
首先对Ti6Al7Nb牙种植体进行表面清洁，去除其表层金属碎屑、杂质、油脂等，再将牙种植体置入重铬酸钾与水的质量比为1:100的溶液中，加热该溶液至沸腾，使牙种植体在沸腾的溶液中处理15分钟，处理完毕的牙种植体用无水乙醇清洗，自然晾干。牙种植体的表面，牙种植体的表面硬度和整体强度得以提高。
实施例2
