In the era of adhesive dentistry, there are constant and continual advancements in the areas of the materials that are used to restore teeth. Bonding agents have gone through several generations in attempts to decrease chair time and increase strength, and composites are constantly adjusting the ratios of various particle sizes to gain that perfect harmony of functionality and esthetics.

However, through all of these changes, very little has been changed about the instruments with which the items are placed. In a dentist’s composite armamentarium the instruments are often the weakest link, which, in some cases, can lead to a compromise of the final composite restoration.

In this case I’m talking about the pullback phenomenon that many dental composites can exhibit when sculpting. This pullback occurs when the composite material sticks to the micro-scratches in the surface of commonly used stainless steel instruments. These scratches, which can occur from just daily ultrasonic and sterilization processes, create a rough surface for the composite to grab onto and thus be pulled away from the preparation area. This pullback effect can end up creating voids in the final restoration and can also create the need for spending unnecessary time finishing the restoration to proper contours. This is ultimately true in direct anterior composite cases where a majority of the contours should be created through the material placement prior to finishing.

The ability to have a composite instrument with a smooth surface then becomes paramount to not only save time, but to have a predictable restoration. American Eagle has applied a multilayered TiN/Ti surface-engineering process that creates a non-porous and wear-resistant surface to its line of composite instruments.

This TiN process gives you the final element of control that is needed for perfect sculptability of your composites. There is no pullback effect from the TiN instruments, enabling the composite to be sculpted to the proper anatomy either in the anterior or posterior before curing and thus saving time during the finishing process and creating an esthetic and void-free restoration. The instruments are lightweight and easy to maneuver with the stainless steel EagleLite™ handle. Also, with TiN Engineered instruments, you know that you will still have the same composite handling ability from the first restoration to the 500th due to the corrosion resistance of the TiN/Ti surface engineering.

American Eagle has created composite instruments that match the technology of the composites in use today. Make sure that you don’t stay stuck using those old stainless-steel instruments. Let TiN engineering help take your composite restorations to the next level. Learn more by visiting www.am-eagle.com, phoning (800) 551-5172 or faxing (406) 549-7452.
