Abstract

Purpose: To evaluate the effect of chemical, mechanical, and combination surface treatments on the shear bond strength (SBS) of autopolymerizing repair resins to conventional heat-cured, computer aided design (CAD)-computer aided manufacturing (CAM) milled, and three-dimensionally (3D) printed denture base materials.

Methods: Specimens were fabricated and divided according to the surface treatment as follows: no surface treatment (control group), monomer treatment (monomer group), resin remover treatment (resin remover group), roughening with 180 FEPA grit abrasive paper followed by monomer treatment (180-grit plus monomer group), and air particle abrasion (air abrasion group). Autopolymerizing resin cylinders were attached before accelerated aging of the specimens in water at 100 °C for 16 h. The SBS was tested using a universal testing machine. Surface roughness was evaluated using a 3D optical profilometer. Scanning electron microscopy (SEM) and stereomicroscopy were used for surface analysis. Data was collected and analyzed using analysis of variance (ANOVA) and Kruskall–Wallis tests (α = 0.05).

Results: The denture base material and surface treatment significantly affected the SBS. The milled Temp Basic Tissue demonstrated the highest SBS values across all surface treatments, whereas the two 3D-printed denture base materials exhibited the lowest SBS values.

Conclusions: The bond strength of CAD-CAM-milled denture base resins to autopolymerizing repair resins is comparable to that of heat-cured resins. Surface roughening using air particle abrasion or 180-grit carbide paper can enhance the bond strength of the autopolymerizing repair resin to 3D-printed denture base materials.

不同表面处理对采用不同技术加工的自动聚合修复树脂与义齿基底材料的剪切粘接强度的影响

目的：评估化学、机械和组合表面处理对自聚合修复树脂与传统热固化、计算机辅助设计（CAD）-计算机辅助制造（CAM）铣削和三维（3D）打印义齿基托材料的剪切粘接强度（SBS）的影响：制作试样，并根据表面处理情况分为以下几组：无表面处理组（对照组）、单体处理组（单体组）、树脂去除剂处理组（树脂去除剂组）、使用 180 FEPA 砂纸粗化后再进行单体处理组（180 砂纸加单体组）和空气颗粒磨蚀组（空气磨蚀组）。在试样于 100 °C 的水中加速老化 16 小时之前，先将自聚树脂圆柱体连接起来。使用 3D 光学轮廓仪评估表面粗糙度。扫描电子显微镜（SEM）和立体显微镜用于表面分析。数据收集和分析采用方差分析（ANOVA）和 Kruskall-Wallis 检验（α = 0.05）：结果：义齿基托材料和表面处理对 SBS 有显著影响。结果：义齿基托材料和表面处理对 SBS 有明显影响。在所有表面处理中，铣制的 Temp Basic Tissue 的 SBS 值最高，而两种三维打印义齿基托材料的 SBS 值最低：结论：CAD-CAM 铣削义齿基底树脂与自聚修补树脂的粘接强度与热固化树脂相当。使用空气颗粒磨料或180目硬质合金纸进行表面粗化可以提高自聚合修复树脂与三维打印义齿基托材料的粘接强度。

期刊介绍： Journal of Prosthodontic Research is published 4 times annually, in January, April, July, and October, under supervision by the Editorial Board of Japan Prosthodontic Society, which selects all materials submitted for publication. Journal of Prosthodontic Research originated as an official journal of Japan Prosthodontic Society. It has recently developed a long-range plan to become the most prestigious Asian journal of dental research regarding all aspects of oral and occlusal rehabilitation, fixed/removable prosthodontics, oral implantology and applied oral biology and physiology. The Journal will cover all diagnostic and clinical management aspects necessary to reestablish subjective and objective harmonious oral aesthetics and function. The most-targeted topics: 1) Clinical Epidemiology and Prosthodontics 2) Fixed/Removable Prosthodontics 3) Oral Implantology 4) Prosthodontics-Related Biosciences (Regenerative Medicine, Bone Biology, Mechanobiology, Microbiology/Immunology) 5) Oral Physiology and Biomechanics (Masticating and Swallowing Function, Parafunction, e.g., bruxism) 6) Orofacial Pain and Temporomandibular Disorders (TMDs) 7) Adhesive Dentistry / Dental Materials / Aesthetic Dentistry 8) Maxillofacial Prosthodontics and Dysphagia Rehabilitation 9) Digital Dentistry Prosthodontic treatment may become necessary as a result of developmental or acquired disturbances in the orofacial region, of orofacial trauma, or of a variety of dental and oral diseases and orofacial pain conditions. Reviews, Original articles, technical procedure and case reports can be submitted. Letters to the Editor commenting on papers or any aspect of Journal of Prosthodontic Research are welcomed.
