A Comparative Study to Evaluate the Compression Resistance of Different Interocclusal Recording Materials: An In Vitro Study.

Journal of Indian Prosthodontic Society

Nagrath R, Lahori M, Kumar V, Gupta V.
PMID: 26199495
J Indian Prosthodont Soc. 2014 Dec;14:76-85. doi: 10.1007/s13191-014-0369-8. Epub 2014 Jul 17.

Recording and transferring of accurate existing occlusal records is of prime importance for a successful restoration. An ideal occlusal registration material should provide minimal resistance to mandibular closure during the registration of maxillomandibular relationships. Interocclusal bite registration materials are...

Layer-by-layer assembled membranes of protonated 18-azacrown-6 and polyvinylsulfate and their application for highly efficient anion separation.

The journal of physical chemistry. B

El-Hashani A, Toutianoush A, Tieke B.

J Phys Chem B. 2007 Jul 26;111(29):8582-8. doi: 10.1021/jp0688052. Epub 2007 Apr 06.

Ultrathin separation membranes were prepared upon alternating electrostatic adsorption of 1,4,7,10,13,16-hexaazacyclooctadecane (18-azacrown-6, hexacyclen, aza6) and polyvinylsulfate on porous polyacrylonitrile/polyethylene terephthalate (PAN/PET) substrates. The resulting composite membranes were highly permeable for electrolyte solutions, but the selectivity in ion transport was...

The release of monovalent counterions by addition of divalent counterions in coulombic interaction system of polyions (II).

Biophysical chemistry

Miyamoto S.
PMID: 17000178
Biophys Chem. 1981 Dec;14(4):341-6. doi: 10.1016/0301-4622(81)85036-3.

In this work, the increase in activity. Deltaa+ of a monovalent counterion (Na+) resulting from the addition or a divalent ion (Cu2+) was experimentally investigated in sulfate or sulfonate polyelectrolyte solutions. It was found that in the case of...

Fabrication of microcellular SiCN ceramics from templated polyvinylsilazane with expandable microspheres.

Journal of nanoscience and nanotechnology

Hong LY, Ryu SH, Kim DP.
PMID: 21137780
J Nanosci Nanotechnol. 2010 Oct;10(10):6672-6. doi: 10.1166/jnn.2010.2506.

The microcellular SiCN ceramics with high porosity and high surface area were fabricated from polysilazane as a viscous SiCN ceramic precursor and expandable microspheres as a self-sacrificial template. The fabrication steps were composed of (1) forming of expandable microsphere...

Preparation of a polypyrrole-polyvinylsulphonate composite film biosensor for determination of cholesterol based on entrapment of cholesterol oxidase.

Sensors (Basel, Switzerland)

Sensors (Basel). 2009;9(8):6435-45. doi: 10.3390/s90806435. Epub 2009 Aug 20.

In this paper, a novel amperometric cholesterol biosensor with immobilization of cholesterol oxidase on electrochemically polymerized polypyrrole-polyvinylsulphonate (PPy-PVS) films has been accomplished via the entrapment technique on the surface of a platinum electrode. Electropolymerization of pyrrole and polyvinylsulphonate on...

Maru K, Dwivedi A, Agarwal J, Vyas A, Jain S, Kulkarni P.
PMID: 29962777
Contemp Clin Dent. 2018 Jun;9:S127-S132. doi: 10.4103/ccd.ccd_120_18.

BACKGROUND: Majority of general dental practitioners provide fixed dental prosthesis in India. The aim of this study was to gather information on selection, usage, and materials and methods employed in interocclusal records and their communication with the dental laboratory...

Novel Pathway for Efficient Covalent Modification of Polyester Materials of Different Design to Prepare Biomimetic Surfaces.

Polymers

PMID: 30961224
Polymers (Basel). 2018 Nov 23;10(12). doi: 10.3390/polym10121299.

To form modern materials with biomimic surfaces, the novel pathway for surface functionalization with specific ligands of well-known and widely used polyester-based rigid media was developed and optimized. Two types of material bases, namely, poly(lactic acid) and poly(ε-caprolactone), as...

The Influence of a Flexible Model on the Marginal Adaptation of Inlay Composite Restorations: A MicroCT Analysis.

The European journal of prosthodontics and restorative dentistry

Villanueva MV, Balbinot GDS, Mogollon GH, Leitune VCB, Collares FM.
PMID: 34982864
Eur J Prosthodont Restor Dent. 2021 Dec 22; doi: 10.1922/EJPRD_2351Villanueva07. Epub 2021 Dec 22.

The aim of this study was to evaluate the influence of flexible models on the marginal adaptation of indirect resin composite restorations. Thirty-six cavity preparations were made for class II restorations in permanent molar teeth. Three groups (n=12) were...
