The aim of this study was to assess surface characteristics, element composition, and surface roughness of five different commercially available dental zirconia implants. Five zirconia implants (Bredent whiteSKY™ (I1), Straumann® PURE Ceramic (I2), ceramic.implant vitaclinical (I3), Zeramex® (I4), Ceralog Monobloc M10 (I5)) were evaluated.
The evaluation was performed by means of scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and confocal laser scanning microscopy (CLSM).
The semi-quantitative element composition showed no significant impurity of any implant tested. Both the machined and the rough areas of the investigated implants were predominated by zirconium, oxygen, and carbon. Roughness values (S) showed highest values for I2 and I5.
The investigated zirconia implants showed surface characteristics and roughness values close to those of conventionally produced titanium implants, making them a promising alternative. However, zirconia implants have yet to prove themselves in clinical practice and clinical controlled trials.
本研究的目的是评估五种不同的市售牙科氧化锆种植体的表面特性、元素组成和表面粗糙度。评估了五种氧化锆种植体(Bredent whiteSKY™(I1)、Straumann® PURE Ceramic(I2)、ceramic.implant vitaclinical(I3)、Zeramex®(I4)、Ceralog Monobloc M10(I5))。
通过扫描电子显微镜(SEM)、能量色散X射线光谱(EDX)和共聚焦激光扫描显微镜(CLSM)进行评估。
半定量元素组成显示,所测试的任何种植体均无明显杂质。所研究种植体的加工区域和粗糙区域均以锆、氧和碳为主。粗糙度值(S)在I2和I5中最高。
所研究的氧化锆种植体的表面特性和粗糙度值与传统生产的钛种植体相近,使其成为一种有前景的替代品。然而,氧化锆种植体尚未在临床实践和临床对照试验中得到验证。
