Factors influencing mechanical and wear performance of dental composite: A review

Abstract

With environmental concerns, the development of a posterior restorative as a true alternative to dental amalgam is needed. Hence in this regard, the development of dental composites have gained more and more research interest, as they have the advantages of better aesthetic look, better physical, mechanical and tribological properties over the other available dental materials. In this study, the physical, mechanical and wear behavior of dental composite materials have been reviewed. Numerous experimental results, analytical studies and their significance were also discussed for various dental composite materials. The wear performances of dental composite materials depend up on various factors including oral environment, resin chemistry, filler technology and interfacial bonding strength etc. In oral environment, the presence of medium such as water, air, heptane, ethanol, artificial saliva etc. and durations up to which composite is kept such as seven days, one month or three months etc. affect the performance of dental composite. Abrasion and erosion are two major causes for the wear behavior of dental composite / human teeth. The major issue, most significant challenges and effect of each of those factors affecting the performance of dental composite materials were also presented along with some recommendation.

Performance evaluation of glass ionomer and alumina‐silica nanoparticle reinforced dental composite using preference selection index

“…Therefore, as compared to dental composite without nanofiller and glass ionomer, that is, DC-O, dental composite with nanofiller and glass ionomer exhibited better performance in all the criteria. This result is in-agreement with various literatures [32,33] in which it was reported that nanofiller and glass ionomer enhanced the physical, mechanical, and wear performance of dental composite. Finally, it can be concluded that despite of more void content and low flexural strength, glass ionomer has shown comparable properties with respect to nanosilica and significant properties with respect to nanoalumina.…”

Comparative investigation of fabrication, roughness, mechanical and wear properties of glass ionomer and nanofillers reinforced dental composite: A review

“…However, optimum composition of fillers should be used to obtain optimized physical, mechanical and clinical performance [37]. For comparative investigation of effect of ceramic nanofiller and glass ionomer cement, the most commonly used mechanical characterization methods include compressive strength (CS), flexural strength (FS), diametral tensile strength (DTS), fracture toughness (FT), microhardness (Knoop (KHN) or Vickers (VHN)), wear rate (WR), fatigue and creep [38][39][40].…”

Effect of wood flour and nano‐SiO2 on stimulus response, mechanical, and thermal behavior of 3D printed polylactic acid composites

“…Better performance of composite can be achieved by using the concept of nanotechnology. Addition of nanofiller enhanced the mechanical properties of polymer composite 12–14 . The mechanical properties and thermal resistance of WPC was improved by adding nanosilica filler 15,16 .…”

“…Addition of nanofiller enhanced the mechanical properties of polymer composite. [12][13][14] The mechanical properties and thermal resistance of WPC was improved by adding nanosilica filler. 15,16 Biodegradable and biocompatible polymers exhibit "shape recovery property" which allows them to quickly recover their original shape under the environment temperature more than glass transition temperature.…”
