摘要

最近医疗领域的进步导致了预期寿命的延长和老年人口的增加。因此,骨骼健康的恶化和向以碳水化合物为基础的饮食习惯的转变导致牙齿脱落的增加,从而导致钛植入物的使用增加。钛及其合金由于其固有的特性,如生物相容性、耐腐蚀性、低弹性模量和高强度,是制造骨科和牙科植入物的首选材料。有研究通过开发新的制造方法来进一步改善其医疗性能。本研究主要通过表面刻蚀、功能化和羟基磷灰石涂层等方法来改善钛种植体的生物相容性。用硫酸和盐酸对钛植入物进行电化学酸蚀,在氧化钾溶液中阳极氧化,在室温下用SBF包覆羟基磷灰石。

Alkaline and acidic anodization of titanium implants using electrochemistry
Recent advancements in the medical field has lead to the prolongation of life expectancy and an increase in the elderly population. Consequently, the deterioration of bone health and a shift towards carbohydrate-based dietary habits has lead to an increase in tooth loss and thus to an increase in the use of titanium implants. Titanium and alloys due to their inherent properties such as biocompatibility, corrosion resistance, lower elastic modulus and high strength are preferred in the manufacture of orthopedic and dental implants. There are studies conducted on the further improvement of its medical properties through the development of new manufacturing methods. In this study, improvement of the biocompatibility of Titanium implants by surface etching, functionalization and hydroxyapatite coating has been investigated. Titanium implants been have electrochemically acid-etched using sulphuric and hydrochloric acid, anodized in potassium oxide solution and hydroxyapatite coated in SBF at room temperature.
