Dental Tribune Canada Edition | November 2015 INDUSTRY American Eagle composite instruments strive to provide the long-lasting, non-stick control needed for efficient, esthetic sculpting of today’s constantly improving composites and bonding materials. Photo/Provided by American Eagle Instruments Titanium instruments improve control over advanced restoration materials ticle 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 com- posite armamentarium the instruments are often the weakest link, which, in some cases, can lead to a com- promise of the final composite restoration. In this case I’m talking about the pullback phenom- enon 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 finish- ing the restoration to proper contours. This is ultim- ately 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. Amer- Smooth surface ends the pullback often seen when sculpting with stainless steel ican Eagle has applied a multilayered TiN/Ti surface- engineering process that creates a non-porous, wear- resistant surface to its line of composite instruments. This TiN process gives you the final element of con- trol 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 finish- ing process and creating an esthetic and void-free res- toration. The instruments are lightweight and easy to man- euver 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 corro- sion resistance of the TiN/Ti surface engineering. American Eagle has created composite instruments that match the technology of the composites in use to- day. Make sure that you don’t stay stuck using those old stainless-steel instruments. Let TiN engineering help take your composite res- torations to the next level. Learn more by visiting www. am-eagle.com, phoning (800) 551-5172 or faxing (406) 549-7452. Ad By Cappy Sinclair, DDS Coastal Cosmetic Dentistry Virginia Beach, Va. In the era of adhesive dentistry, there are constant and continual advancements in the areas of the ma- terials that are used to restore teeth. Bonding agents have gone through several generations in attempts to decrease chair time and increase strength, and compos- ites are constantly adjusting the ratios of various par- By Prof. Giovanni Olivi, MD, DDS University of Genoa, Italy A patient asked for the option to save her teeth that were scheduled for extraction by another dentist. The lower left first and second molars had high mobil- ity (grade 2), were necrotic, with significant probing depths in the buccal aspect. The teeth were diagnosed for endo/perio treatment. Difficulties with this case included complex radicular anatomy, long anatomical measurements (26 and 27 mm respectively for #36 and 37) and the presence of a deep vertical bone loss in the buccal aspect. After scal- ing and root planning, the teeth were scheduled for root–canal therapy. Before treatment: PIPs Before each treatment the PIPS™ technique was ap- plied into the periodontal pockets of each tooth for refining the debridement, removal of biofilm from the root surfaces and pocket disinfection. The root canal treatments were performed using PIPS–specific irrigation protocols with 5 percent NaOCl and 17 percent EDTA. Obturation with resin sealer The canals were obturated with a flowable resin sealer (Endoreze Ultradent, South Jordan, Utah) and gutta– percha points. A final treatment of the pockets using PIPS for disinfection was performed after completing each root canal therapy to remove any extruded sealer or residual biofilm. No post–op symptoms were reported and the mobil- ity of the teeth progressively disappeared up to grade 0. The follow-up X–rays performed after one and four months showed healing in progress for both the teeth. Lightwalker AT laser device with contact H14–C hand- piece and PIPS fiber tip was used for the treatment. The Lightwalker parameters are: laser source: Er:YAG; wavelength: 2940 nm; pulse duration: SSP; energy: 15 mJ; frequency: 15 Hz.
