The effect of poly(methyl methacrylate) surface treatments on the adhesion of silicone-based resilient denture liners

Purpose. The objective of this systematic review is to compare results concerning the properties of adhesion, roughness, and hardness of dental liners obtained in the last ten years. Methods. Searches on the databases LILACS, PubMed/Medline, Web of Science, and Cochrane Database of Systematic Reviews were supplemented with manual searches conducted between February and April of 2018. The inclusion criteria included experimental in vitro and in vivo, clinical, and laboratory studies on resilient and/or hard liners, assessment of hardness, roughness, and/or adhesion to the denture base, and physical/mechanical changes resulting from the disinfection process and changes in liners’ composition or application. Results. A total of 406 articles were identified and, from those, 44 are discussed. Twenty-four studies examined the bond strength, 13 surface roughness, and 19 the hardness. Of these 44 studies, 12 evaluated more than one property. Different substances were used in the attempt to improve adhesion. Considering roughness and hardness, the benefits of sealants have been tested, and the changes resulting from antimicrobial agents’ incorporation have been assessed. Conclusion. Adhesion to the prosthesis base is improved with surface treatments. Rough surfaces and changes in hardness compromise the material’s serviceability.

“…Depending on the surface hardness, the lining materials are divided into hard liners such as PMMA [ 78 , 158 ]; and resilient liners. The resilient liners are elastic and composed of silicone elastomers [ 159 , 160 , 161 ], which act as shock absorber [ 161 ]. Both heat- and cold-cured PMMA materials are used for the relining of dentures (hard relining), using the old denture as an impression tray [ 10 ].…”

Prosthodontic Applications of Polymethyl Methacrylate (PMMA): An Update

2020

A wide range of polymers are commonly used for various applications in prosthodontics. Polymethyl methacrylate (PMMA) is commonly used for prosthetic dental applications, including the fabrication of artificial teeth, denture bases, dentures, obturators, orthodontic retainers, temporary or provisional crowns, and for the repair of dental prostheses. Additional dental applications of PMMA include occlusal splints, printed or milled casts, dies for treatment planning, and the embedding of tooth specimens for research purposes. The unique properties of PMMA, such as its low density, aesthetics, cost-effectiveness, ease of manipulation, and tailorable physical and mechanical properties, make it a suitable and popular biomaterial for these dental applications. To further improve the properties (thermal properties, water sorption, solubility, impact strength, flexural strength) of PMMA, several chemical modifications and mechanical reinforcement techniques using various types of fibers, nanoparticles, and nanotubes have been reported recently. The present article comprehensively reviews various aspects and properties of PMMA biomaterials, mainly for prosthodontic applications. In addition, recent updates and modifications to enhance the physical and mechanical properties of PMMA are also discussed.

The SFE analysis is used to estimate the chemical state of a material surface 15,[31][32][33][34][35][36][37][38][39][40] . We reported that the SFE is strongly correlated to the microstructure of the CAD/CAM composite, affecting its adhesion to the resin cement in our previous report 15) .…”
