A Novel, Zero Shrinkage Dental Composite

 

Introduction

 

The technology relates to polymeric biomaterials more specifically for restorative dentistry, broadly to a composition for an organic resin matrix which can be used for cementation of implants, endodontic sealers, root repair materials, root end filling materials, and luting cements. The new composite developed does not shrink or elute and hence is more biocompatible. The low cytotoxicity of the dental composite is a result of low elution of undesirable substances. Another advantage of the new formulation is that it has more than 50% reduction in the exothermic heat of polymerization, further making it tissue friendly during the curing reaction. These properties qualify the material for other biomedical uses like bone cement apart from dental restorations.

 

Market

 

The Global Dental Restorative Materials Market has been evaluated as rapidly growing market and it is projected to grow significantly at a steady CAGR of 5.5% during 2016 to 2022. There has been a tremendous growth in the number of people getting their teeth fixed. People are becoming more aware about the aesthetic value of the perfect and healthy teeth. Damage in the teeth in most cases is directly linked with the eating habits. Children under age 12 are more prone to damage their teeth because of the eating chocolates and sweets and not taking proper care of the teeth. Rise in the accidental cases has also heavily boosted the dental industry.

 

Validation

 

In vitro cytotoxicity tests were done in external labs ; Photo-DSC was done in NETZ lab, Germany. The composite material has been compared with the Conventional materials for various aspects such as degree of conversion, elution, shrinkage, cytotoxicity etc and found to be better as depicted in the graphs. The U, G, T and E are experimental compositions which clearly show higher degree of conversion, low cytotoxicity and negative shrinkage ( U and T )
