Abstract

To investigate how patterns generated by femtosecond (fs) laser and femtosecond laser power affect the surface roughness (Ra) and biaxial flexural strength (BFS) of monolithic zirconia. Eighty disk-shaped zirconia specimens were divided into eight subgroups (n = 10): Control (C), airborne-particle abrasion (APA), 400 mW fs laser (spiral [SP(400)], square [SQ(400)], circular [CI(400)]), and 700 mW fs laser ([SP(700)], [SQ(700)], [CI(700)]). Ra values were calculated by using a surface profilometer. One additional specimen per group was analyzed with scanning electron microscopy and x-ray diffractometry. BFS values were obtained by using the piston-on-3-ball test. One-way ANOVA and either Tukey's HSD (BFS) or Tamhane's T2 (Ra) tests were used to evaluate data (α = 0.05). Regardless of the pattern and power, fs laser groups had higher Ra than C and APA, while SP groups had lower Ra than CI and SQ groups (p ≤ 0.004). For each pattern, Ra increased with higher laser power (p < 0.001), while the laser power did not affect the BFS (p ≥ 0.793). CI and SQ groups had lower BFS than the other groups (p ≤ 0.040), whereas SP groups had similar BFS to C and APA (p ≥ 0.430). Fs laser microstructuring with spiral surface pattern increased the Ra without jeopardizing the BFS of zirconia. Thus, this treatment might be an option to roughen tested zirconia.

飞秒激光诱导表面图案对整体氧化锆抗弯强度的影响
研究飞秒(fs)激光产生的图案和飞秒激光功率如何影响整体氧化锆的表面粗糙度(Ra)和双轴抗弯强度(BFS)。80 个圆盘状氧化锆试样被分为 8 个亚组(n = 10):对照组 (C)、空气颗粒磨损 (APA)、400 mW fs 激光(螺旋形 [SP(400)]、方形 [SQ(400)]、圆形 [CI(400)])和 700 mW fs 激光([SP(700)]、[SQ(700)]、[CI(700)])。Ra 值使用表面轮廓仪计算。每组还有一个试样用扫描电子显微镜和 X 射线衍射仪进行分析。BFS 值通过活塞-3 球测试获得。采用单因子方差分析和 Tukey's HSD(BFS)或 Tamhane's T2(Ra)检验来评估数据(α = 0.05)。无论采用哪种模式和功率,fs 激光组的 Ra 值都高于 C 组和 APA 组,而 SP 组的 Ra 值则低于 CI 组和 SQ 组(p ≤ 0.004)。对于每种模式,Ra 随激光功率的增加而增加(p

期刊介绍: Journal of Biomedical Materials Research – Part B: Applied Biomaterials is a highly interdisciplinary peer-reviewed journal serving the needs of biomaterials professionals who design, develop, produce and apply biomaterials and medical devices. It has the common focus of biomaterials applied to the human body and covers all disciplines where medical devices are used. Papers are published on biomaterials related to medical device development and manufacture, degradation in the body, nano- and biomimetic- biomaterials interactions, mechanics of biomaterials, implant retrieval and analysis, tissue-biomaterial surface interactions, wound healing, infection, drug delivery, standards and regulation of devices, animal and pre-clinical studies of biomaterials and medical devices, and tissue-biopolymer-material combination products. Manuscripts are published in one of six formats: • original research reports • short research and development reports • scientific reviews • current concepts articles • special reports • editorials Journal of Biomedical Materials Research – Part B: Applied Biomaterials is an official journal of the Society for Biomaterials, Japanese Society for Biomaterials, the Australasian Society for Biomaterials, and the Korean Society for Biomaterials. Manuscripts from all countries are invited but must be in English. Authors are not required to be members of the affiliated Societies, but members of these societies are encouraged to submit their work to the journal for consideration.
