Properties of a novel composite elastomeric polymer vinyl polyether siloxane in comparison to its parent materials: a systemic review and meta-analysis

Abstract

Background The effectiveness of newly developed elastomeric polymer hybrid siloxane (PVES), which combines the properties of polyethylene (PE) and polyvinyl siloxane (PVS) elastomers, has been a subject of interest in recent studies. This study aimed to assess the physical properties of hybrid PVES materials by analyzing existing data from recent studies on this topic. Methods A systematic literature search was conducted to retrieve peer-reviewed articles published up to February 5, 2023. The population, intervention, comparison, and pertinent outcomes were specified under the PICO framework. The primary data analysis was performed in Microsoft Excel, while statistical analysis used Meta-Essentials. Results Of the 1152 articles assessed, 14 met the inclusion criteria. The meta-analysis of the selected studies indicated that polyether (PE) and polyvinyl siloxane (PVS) were highly correlated (two-tailed p-values of 0.000 and 0.001, respectively) with the improved tensile strength of vinyl polyether siloxane (PVES) with a significantly positive effect size. Similarly, the hydrophilic characteristics of PVES were significantly improved compared to those of PE and PVS. PE was a significant contributor to the hydrophilic characteristics of PVES, with a two-tailed p-value of 0.000. The effect size was highly positive for hydrophilicity but showed high heterogeneity. It was also observed that the dimensional accuracy of PVES was comparable to those of PE and PVS, with no statistically significant differences among the three materials. Conclusions PVES showed promising features, with improved tensile strength and hydrophilic characteristics compared to those of PE and PVS.

Evaluation of the effect of chemical disinfection and ultraviolet disinfection on the dimensional stability of polyether impression material: an in-vitro study

“…Recently, impression materials have been directly integrated with antimicrobials and nanoparticles, enabling the material to possess self-disinfecting properties. This innovation not only ensures the internal disinfection of the impression material but also extends to disinfecting the impressions from the moment they are introduced into the patient’s mouth [ 10 , 11 ].…”

A Newly Formulated Vinyl Polysiloxane Impression Material with Improved Mechanical Properties

“…[ 5 , 6 ] Although digital impression has gained great interest and some progress has been made in recent years,[ 7 ] adopting digitization is still costly and may take much longer time to significantly unfold; therefore, most clinicians continue to use a lot of different impression materials,[ 8 ] and major companies and some researchers continue to improve some properties of impression materials and to invent novel impression materials. [ 9 , 10 , 11 , 12 , 13 , 14 ] This can be evidenced by the consumption of impression materials in the US market. According to IData research, the total value of the impression materials market in the U.S. exceeded $245 million in 2016 and will be $262.4 million in 2023.…”
