Fill-Up! – a new bulk fill composite from Coltene – has recently been at the receiving end of both recommendations and recognition from patients and dental professionals alike. With this in mind, NIHR asked Simon Killough, a Consultant in Restorative Dentistry in the Belfast Trust, to put the product to the test.

Fill-Up! is a newly-launched dualcured bulk fill composite from Coltene, which is recommended for all Class I and II cavities, cavity lining, and core build-ups in the posterior region. The product is applied in a single step, and can be finished with rotary instruments immediately after application. As well as that, it polishes to a high lustre and is a convenient material when a fast and aesthetic restoration is required.

THE SKY’S THE LIMIT

While conventional light-cured bulk filling materials are limited in their curing depth to 2 – 3mm increments, the dual curing properties of FillUp! guarantees a thorough curing down to the bottom of the cavity. It is possible to place the material to a maximum layer of 10mm. Additionally, chemical curing reduces shrinkage stress, preventing micro fractures and postoperative sensitivity – a common clinical problem following composite placement.

EASY DOES IT

Fill-Up! restorations can be completed quickly, with a single light cure of five seconds, coupled with the aforementioned dual cure capabilities. No ‘top-layer’ is required as there are superior mechanical properties, and a single universal shade (Vita A2- A3) ensures excellent self-blending properties. Meanwhile, the simple auto-mix dispenser also ensures a rapidly-placed restoration. It exhibits a very low surface roughness after polishing, resulting in highly lustrous results. The chemical properties and dual-cured nature demonstrates minimal polymerisation shrinkage, comparable with other composite materials. When used with the ParaBond dentine bonding agent, there is optimal marginal sealing, giving attractive aesthetics and reduced incidence of marginal breakdown. Also notable is the fact that the material contains zinc oxide, giving radioopacity for monitoring purposes.

A DIVERSE CHOICE

I see this material being useful for a variety of clinical indications – especially as more and more patients are demanding aesthetic restorations for posterior teeth and wish to avoid the use of dental amalgam. It’s especially useful for patients who cannot tolerate prolonged treatment sessions, by virtue of its rapidity of placement and ease of use – such as patients who are elderly, have special needs, medical issues, and those who are following radiotherapy, or dental anxiety. It gives superior handling properties and can be dispensed directly into the cavity.

Nevertheless, it’s important to bear in mind that it won’t be appropriate for every clinical situation, and the availability of only one shade may not suit the most discerning patient.

In conclusion, Fill-Up! is an excellent addition for the busy dental practitioner’s restorative materials; ideally suited for simple, effective aesthetic restorations, and offers a cost-effective solution for many situations.
