Abstract

Background and aim: Computer-aided design/computer-aided manufacturing (CAD/CAM)-fabricated space maintainers offer a reliable alternative to traditionally fabricated stainless steel (SST) appliances, avoiding their commonly encountered drawbacks. The aim of this study is to evaluate the shear peel bond strength of the CAD/CAM polyetheretherketone (PEEK) space maintainer in comparison with an SST one.

Materials and methods: The study was conducted on 50 molars, divided into two groups: a customized PEEK band (study group) and a prefabricated SST orthodontic molar band (control group). The crowns of the study group were scanned using a lab scanner, the bands were designed using ExoCAD software, and the PEEK disks were milled. The inner surfaces of the PEEK bands were sandblasted, etched, rinsed, and dried. Both bands were cemented to the teeth using self-etch dual-cure resin cement. The sheer peel bond of the bands was tested twice, both before and after cementation, using an electromechanical tensile universal testing machine. The data were analyzed using Statistical Package for the Social Sciences (SPSS) software.

Results: Prior to cementation, the peel bond strength of the PEEK band (0.02 ± 0.01) was significantly higher than the SST band (0.01 ± 0.00) (p = 0.000). Additionally, the PEEK band's shear peel bond strength (0.58 ± 0.18) following cementation with self-etch dual-cure dental resin cement was considerably higher than the SST band's shear peel bond strength (0.49 ± 0.24) (p = 0.04).

Conclusion: PEEK bands designed with CAD/CAM technology showed a better shear peel bond than SST bands, both before and following cementation, which imply that PEEK might provide a dependable alternative for traditional SST bands used in pediatric dentistry.

计算机辅助设计/计算机辅助制造空间保持器用聚醚醚酮带剪切剥离结合强度评价:体外研究
背景和目的:计算机辅助设计/计算机辅助制造(CAD/CAM)制造的空间维护器为传统制造的不锈钢(SST)设备提供了可靠的替代方案,避免了它们通常遇到的缺点。本研究的目的是评估CAD/CAM聚醚醚酮(PEEK)空间保持剂与SST空间保持剂的剪切剥离结合强度。材料与方法:研究对象为50颗磨牙,分为两组:定制PEEK带(研究组)和预制SST正畸磨牙带(对照组)。使用实验室扫描仪扫描研究组的冠,使用ExoCAD软件设计条带,并铣削PEEK磁盘。PEEK带的内表面经过喷砂、蚀刻、冲洗和干燥。使用自蚀刻双固化树脂胶粘剂将两根牙带粘接在牙齿上。使用机电拉伸万能试验机对胶结前后的纯剥离粘结进行了两次测试。采用SPSS (Statistical Package for The Social Sciences)软件对数据进行分析。结果:胶结前PEEK带剥离结合强度(0.02±0.01)显著高于SST带剥离结合强度(0.01±0.00)(p = 0.000)。此外,自蚀刻双固化牙体树脂胶结后PEEK带的剪切剥离结合强度(0.58±0.18)明显高于SST带的剪切剥离结合强度(0.49±0.24)(p = 0.04)。结论:应用CAD/CAM技术设计的PEEK带在骨水泥前和骨水泥后均比SST带具有更好的剪切剥离粘合性,这意味着PEEK可能是传统SST带在儿科牙科应用的可靠替代品。如何引用本文:Mohamed OS, Karawia I, Gaber AH等。计算机辅助设计/计算机辅助制造空间保持器用聚醚醚酮带剪切剥离结合强度评价:体外研究中华临床儿科杂志,2015;18(1):75-79。
