This study investigates a wide range of clinically relevant mechanical properties of poly(methyl methacrylate) (PMMA) denture base materials modified with di-methyl itaconate (DMI) and di-n-butyl itaconate (DBI) in order to compare them to a commercial PMMA denture base material. The commercial denture base formulation was modified with DMI and DBI by replacing up to 10 wt% of methyl methacrylate (MMA) monomer. The specimens were prepared by standard bath curing process. The influence of the itaconate content on hardness, impact strength, tensile, and thermal and dynamic mechanical properties was investigated. It is found that the addition of di-n-alkyl itaconates gives homogenous blends that show decreased glass transition temperature, as well as decrease in storage modulus, ultimate tensile strength, and impact fracture resistance with increase in the itaconate content. The mean values of surface hardness show no significant change with the addition of itaconates. The magnitude of the measured values indicates that the poly(methyl methacrylate) (PMMA) denture base material modified with itaconates could be developed into a less toxic, more environmentally and patient friendly product than commercial pure PMMA denture base material.

Denture Base Resin

Knowledge about the influence of fillers in denture base resin is vague. This systematic review aimed to report the reinforcing effect of fillers on the mechanical properties of denture base resin by following PRISMA guidelines. Two electronic databases (Pubmed/Medline & Web of Science) were searched for articles using the keywords: fibers in denture base, fillers in denture base, and reinforcement of denture base. Laboratory studies complying with the inclusion criteria were reviewed according to the set protocol. The established focus question was: “Do reinforcing fillers positively influence the mechanical properties of polymethyl methacrylate (PMMA) heat polymerized denture base material?” A total of twenty-nine relevant papers qualified for final inclusion. Of these, 24 were determined to have a moderate risk of bias. Micron or nano-sized metal/metal oxides particles and glass fibers were the frequently used reinforcing agents. The trend of evaluating fractural strength (FS) was common. Most of the studies limited the use of reinforcing agents up to 5 wt.%. FS, fracture toughness (FT), and impact strength (IS) tend to increase if the fillers are chemically bonded and well-dispersed in denture base resin. Though fillers with a higher elastic modulus increase the hardness of the reinforced denture base resin, they compromise other mechanical properties. Well-dispersed lower filler loading PMMA denture base resin can enhance the FS, FT, and other related mechanical properties.

Denture Base

In esthetic restorative dentistry, resin composites are generally encountered. Because of their excellent biocompatibility, lack of taste, odour, tissue discomfort, and toxicity, insolubility in body fluids, ease of use, good clinical/ aesthetic properties, stable colours, optical characteristics, efficient pigmentation, low cost, and repairability, they are becoming more common. Currently used composite resins have some flaws, particularly inconsistent mechanical properties. For a long time, particles of various sizes have been used as fillers to enhance these properties. In prosthodontics, poly(methyl methacrylate) (PMMA) is commonly used as a dental base material. It does, nevertheless, have several weaknesses, including low strength and weak thermal properties. The effects of different sizes of alumina (Al2O3) particles on the poly(methyl ethacrylate) (PMMA) denture base were determined in this experiment. PMMA powder was blended with Al2O3 added to methyl methacrylate (MMA).For PMMA polymeric materials strengthened with Al2O3 (40 nm, 140 nm and 0.3-0.8 μm) in various concentrations, the mechanical properties were studied.Also, the synergetic influence of the three nanoparticle sizes in the resin matrix was studied.Furthermore, thermogravimetric (TGA) analysis and water absorption and solubility characteristics of the composites prepared were also examined. Among the most significant properties to be obtained for good denture materials is high mechanic properties, water absorption and solubility, since they have different attributes in the aqueous condition of the oral cavity. Results showed clear properties optimization, especially for the size-hybrid alumina composites.
