    摘要:

    加速和改善骨結(jié)合過程是口腔種植領(lǐng)域的研究熱點(diǎn),電刺激成骨是其中的研究方向之一,但外源性電刺激目前還存在很多缺陷。鑒于骨本身具有壓電特性,如能在鈦種植體表面制備壓電材料涂層,從而產(chǎn)生內(nèi)源性電刺激來促進(jìn)成骨就具有重要研究意義。鈦酸鋇作為一種環(huán)境友好的無鉛壓電材料,在四方相具備壓電效應(yīng),生物相容性良好,負(fù)荷條件下可以促進(jìn)成骨。本研究首先利用陽極氧化技術(shù)在鈦種植體表面制備了形貌和結(jié)構(gòu)優(yōu)化的二氧化鈦納米管涂層,進(jìn)而利用水熱反應(yīng)將二氧化鈦納米管涂層轉(zhuǎn)化為鈦酸鋇涂層,通過優(yōu)化實(shí)驗(yàn)參數(shù)并設(shè)置極限濃度探索出具有壓電效應(yīng)的四方相鈦酸鋇涂層的合成條件,并進(jìn)行了表面形貌、晶相等的表征和分析,結(jié)合有限元分析模擬計(jì)算驗(yàn)證涂層顆粒壓電勢(shì),期望為種植體表面改性提供新的思路和方法。

    Abstract:

    Accelerating and improving the process of osseointegration is a research hotspot of oral implantology, and electrical stimulation of osteogenesis is one of the research directions. In view of the bone"s piezoelectric properties and the defects of exogenous electrical stimulation, the application of piezoelectric materials to generate endogenous electrical stimulation to promote osteogenesis is of great significance. As an environmental-friendly lead-free piezoelectric material, barium titanate has a piezoelectric effect in the tetragonal phase. Especially it has good biocompatibility and can promote bone formation under load conditions. Here we used anodic oxidation technology and hydrothermal reaction to construct a barium titanate piezoelectric coating on the titanium surface. By optimizing the experimental parameters and setting the limit concentration, we explored the synthesis conditions of the tetragonal barium titanate coating.Meanwhile, the piezoelectric potential of coating particles was verified by finite element simulation. By modifying the surface of the dental implant, we hope to provide a new method to promote implant osseointegration.
