“…OPEFB significantly increased the flexural strength and flexural modulus of acrylic resin. 23 Short ramie fiber also increased the flexural modulus of acrylic resin compared with conventional PMMA, but its flexural strength decreased as a result of weak interfacial bonding. The drawback of this fiber was its presentation in a long form, which requires extra work, ie, cutting and preparation.…”

This paper reviews acrylic denture base resin enhancement during the past few decades. Specific attention is given to the effect of fiber, filler, and nanofiller addition on poly(methyl methacrylate) (PMMA) properties. The review is based on scientific reviews, papers, and abstracts, as well as studies concerning the effect of additives, fibers, fillers, and reinforcement materials on PMMA, published between 1974 and 2016. Many studies have reported improvement of PMMA denture base material with the addition of fillers, fibers, nanofiller, and hybrid reinforcement. However, most of the studies were limited to in vitro investigations without bioactivity and clinical implications. Considering the findings of the review, there is no ideal denture base material, but the properties of PMMA could be improved with some modifications, especially with silanized nanoparticle addition and a hybrid reinforcement system.

“…Some of the shortcomings of incorporating conventional long or short fibers into denture base polymer mixture would include lack of bonding between the fiber particle and the powder/liquid mixture producing voids, 35 fraying of the margins of the poly-merized specimens noticed during polishing of the specimens, which often occurs due to exposure of the fibers. 36 In this study, however, contrary to the common challenges of placing reinforcement fibers, 16,37 the authors found that MCC was easily and homogeneously added and mixed with the PMMA, and there was no fear of fiber projection in the case of degradation, displacement during processing, or fracture. This shows that the cellulose is evenly distributed in the resin matrix, and the level of impregnation of the MCC with the polymer framework was extremely good.…”

“…They are from renewable resources, considered free of biohazards, and more cost-effective when compared to synthetic fibers; however, mucosal irritation and patient discomfort due to the direct use of long or short fibers in the denture base can lead to clinical problems. 15 One recent study 16 concluded that oil palm empty fruit bunch (OPEFB) in its microcrystalline cellulose (MCC) form can be considered as a viable alternative to existing commercially available synthetic fiber-reinforced denture base resins. MCC is a biodegradable, purified, white, odorless, fine, non-fibrous, and partially depolymerized crystalline powder, usually isolated from cellulose through the hydrolysis process.…”

Purpose To assess the impact of thermal cycling on flexural properties of denture base acrylic resin reinforced with microcrystalline cellulose (MCC) derived from oil palm empty fruit bunch (OPEFB). Materials and Methods The flexural strength and flexural modulus, following thermal cycling (5000 cycles of 5‐55°C) of 3 MCC‐reinforced poly methyl methacrylate (PMMA) specimens were compared with the conventional and commercially available high‐impact PMMA. The 3 test groups were represented by addition of various weight combinations of MCC and acrylic powders. Results All 3 test groups with the addition of MCC demonstrated improved flexural strength and flexural modulus compared to the conventional resin, without and after thermal cycling. The highest mean flexural strength corresponded to the specimens reinforced with 5% MCC followed by 2% MCC. Conclusion Addition of MCC derived from OPEFB to PMMA may be a viable alternative to the existing, commercially available synthetic reinforced PMMA resins. The potential application of natural fillers in the fabrication of a reinforced denture base resin needs further study.

“…ideally FPD (fixed partial denture) base material should have superior surface texture and mechanical properties. in 1936 Walter Wright introduced acrylic resin material called polymethylmethacrylate (PMMA) to the market (Keyf, uzun and Mutlu, 2003;Baba, 2016). This material became one of the most popularly used denture base materials due to its ease of handling and manipulation of the material, it is less toxic, has good aesthetic results, shows adequate strength, easily repaired, the stability in the oral cavity was better when compared with other materials, low solubility, reasonable cost, and low water absorption (Kim and Watts, 2004).…”

The most commonly used material in dentistry is Poly methyl methacrylate (PMMA) which has excellent properties like physical and mechanical properties but this material is rarely used in pure form as it has relatively poor wear resistance and heat resistance. The ideal properties of fixed partial denture (FPD) base material should have superior surface texture and mechanical properties. The wear resistance of heat cure provisional and CAD-CAM provisional vary greatly based on their properties. The aim of this study was to comparatively evaluate the wear resistance in heat cure provisional and cad-cam provisional fixed partial denture. Eight samples each of heat cure provisional and CAD-CAM milled FPD are prepared. The samples are then run for 8 hours in a brushing simulator with a toothpaste to check for its wear resistance .The pre test and post test measurement of its wear resistance is done using laser scan. The wear resistance is more for the CAD-CAM provisional FPD as compared to the heat cure provisional FPD. Pre treatment and post treatment cuspal thickness shows a vast difference in heat cure provisional. However the pre treatment and post treatment cuspal thickness reduction is minimal in CAD CAM provisional FPD. CAD CAM provisional FPD showed better wear resistance than heat cured provisional FPD. Hence CAD CAM prosthesis should be preferred over the heat cured FPD.
