Abstract:A modifier consisting of the mixture of cyclotriphosphazenes containing 4-allyl-2-methoxyphenoxy and β-carboxyethenylphenoxy moieties was developed for administration with acrylate dental restorative compositions. The synthesized compounds were characterized by 1H and 13C NMR spectroscopy and MALDI-TOF mass spectrometry. The optimal conditions to combine the modifier with the starting dental mixture consisting of bis-GMA and TGM-3 were revealed by differential scanning calorimetry (DSC) method. Properties of the cured modified compositions were evaluated for the compliance with requirements of ISO 4049:2019. It was found that these compositions possess the increased adhesion to dental tissues and cure depth and the decreased water sorption and water solubility. The values of elastic modules, destructive compressive stress and microhardness were also increasing along with the increased content of the modifier in the composition.Keywords: phosphazene; restorative dentistry; adhesion; composite material; modification

The staff is friendly and professional. The treatment plan was explained to me in detail. All the interventions were done with my agreement; and whenever there were multiple possibilites for the treatment they let me choose my preferred option. They really put your health and confort first(even if you are afraid of the dentist). And pricewise I consider it to be the best quality money can buy in Timisoara (from my previous experiences) . Even if you require complex interventions you can trust them to help you achieve a beautiful smile. Highly recommend!1 2ff7e9595c
