Nano-hybrid composites rank highly in clinical study

Reported by the dental manufacturer Heraeus USA, its composite Venus Gemstone and Tetric EvoCeram (Ivoclar Vivadent) have accomplished equally satisfying produces a new study carried out by German scientists. Within the study, almost 98 percent from the tooth corrections completed with these composite materials were ranked as either excellent or acceptable by independent dental practitioners.



The 18-month in vivo clinical study was carried out by scientists in the Dental School from the Ludwig Maximilians College of Munich, Germany. They in comparison the clinical effectiveness of Heraeus' Venus Gemstone composite (VD) in posterior direct composite corrections with this of Ivoclar Vivadent's Tetric EvoCeram composite (TE).

Within the study, three dental practitioners placed 48 VD and 50 TE corrections at school I and II tooth decay in 71 patients.

Two independent dental practitioners carried out a clinical assessment before and 1 1 / 2 years after treatment when it comes to 12 criteria, for example surface texture, color match, restoration integrity, occlusion, sensitivity, postoperative signs and symptoms and patient compliance.

Based on Heraeus, 97.8 percent from the VD and 97.1 % from the TE corrections were ranked as scientifically excellent or acceptable.

The dental practitioners ranked 46 VD and 34 TE corrections based on each qualifying criterion on the scale varying from "Alpha" (excellent) to "Delta." Based on Heraeus, VD accomplished mainly Alpha scores with no Charlie or Delta scores.

Record tests revealed no factor between VD and TE concerning failure rates. One VD and something TE restoration needed to be changed prior to the 18-month recall. All teeth were sensitive and no patients reported postoperative signs and symptoms. VD displayed a considerably better surface texture in comparison with TE.

"As much as 18 several weeks, the clinical performance of Venus Gemstone and Tetric EvoCeram exhibit excellent results," stated Professor Jürgen Manhart, who's a restorative material expert and who presented the clinical findings in September 2011 towards the 45th congress from the Continental European Division from the Worldwide Association for Dental Research in Hungary.

Based on the manufacturer, VD is really a nano-hybrid universal composite which has low shrinkage stress and strength qualities and may adapt easily towards the colour of your tooth. The fabric is created utilizing a special gemstone formula, that is based on silica nanoparticles. Several in vitro as well as in vivo research has been carried out on VD recently in The United States, Asia and Europe, with satisfying results overall.

Heraeus is really a gold and silver and technology group using its headquarters in Hanau, Germany. The worldwide private company produces biomaterials and medical items, amongst others.
