To evaluate the effects of ultrasonic scaling (US) and air polishing (AP) on four polyetheretherketone (PEEK) composites.
One hundred-twenty 15 × 3 mm discs of PEEK specimens were divided into four groups (n=30): Unfilled PEEK(U-PEEK), carbon fiber-reinforced PEEK(CFR-PEEK), glass fiber-reinforced PEEK(GFR-PEEK), and ceramic-filled PEEK(CF-PEEK). Each group was further divided into three subgroups (n = 10): control, US, and AP. Profilometry and scanning electron microscopy were used to analyze and evaluate surface roughness (SR). Statistical analyses of the data obtained were conducted using Shapiro-Wilk, Welch, and Games-Howell tests.
When the SR values of the specimens with US cleaning were evaluated, a statistically significant difference was found between the groups (P< 0.05). When the SR values of the specimens with AP cleaning were analyzed, there was a statistically significant difference in the CF-PEEK group (P< 0.05), whereas the other groups were not significantly different (P> 0.05). More studies are needed on CFR-PEEK and GFR-PEEK materials offered as alternatives to CF-PEEK in dentistry.
Dental instruments affect the different PEEK materials, as well as causing surface roughness in many restorative materials used in dentistry. Surface roughness that occurs in dental restorations can cause bacterial adhesion. It is clinically important to choose the dental instrument according to the type of PEEK used for dental implant or prosthetic restoration in the clinic.
评估超声洁牙（US）和空气抛光（AP）对四种聚醚醚酮（PEEK）复合材料的影响。
将 120 个 15×3mm 的 PEEK 试件圆盘分为四组（n=30）：未填充 PEEK（U-PEEK）、碳纤维增强 PEEK（CFR-PEEK）、玻璃纤维增强 PEEK（GFR-PEEK）和陶瓷填充 PEEK（CF-PEEK）。每组进一步分为三个亚组（n=10）：对照组、US 组和 AP 组。采用轮廓仪和扫描电子显微镜分析和评估表面粗糙度（SR）。使用 Shapiro-Wilk、Welch 和 Games-Howell 检验对获得的数据进行统计分析。
当评估经 US 清洁后的试件的 SR 值时，组间存在统计学差异（P<0.05）。当分析经 AP 清洁后的试件的 SR 值时，CF-PEEK 组存在统计学差异（P<0.05），而其他组则无显著差异（P>0.05）。需要对牙科中替代 CF-PEEK 的 CFR-PEEK 和 GFR-PEEK 材料进行更多研究。
牙科器械会影响不同的 PEEK 材料，并导致许多牙科修复材料表面粗糙度增加。牙科修复体中出现的表面粗糙度会导致细菌黏附。在临床中，根据用于牙科植入物或修复体的 PEEK 类型选择牙科器械非常重要。
