Fusion 3.0 Curing Light

Typical curing time is 5 seconds for A3 or lighter shade with 2 mm thickness composite and 4 seconds for metal bracket/3 seconds for ceramic bracket bonding. The table below lists typical curing times for some common composite:

Please use the CURE TIMES instruction from your Users Manual for further details.

Proper composite cures are essential to good restorations that not only avoid tooth sensitivity and rework but also longer lasting tooth and happier return customers.

Four core variables of proper curing are:   

• Curing Light Selection
• Correct Operating Technique
• Proper Composite/Adhesive Selection
• Deliver Required Energy

FUSION has been proven to be the best curing light in power, ease of use and reliability. 

To operate correctly, make sure that the light is directed at the composite as close as possible. Use curing cap as the anchor to the cavity for stable positioning and direction. 

Test the composite outside of the mouth on a piece of paper or even better on a short tube (e.g. 2mm) cut from your compule. Check on the composite hardness on the bottom side to make sure that it is hard enough after your typical curing time. 

FUSION has been proven to deliver the most energy in a given period of time. With a typical curing time of 5 seconds, it easily delivers over 10J/cm2 which is the typical energy required for composite cure.

Traditionally, curing lights are measured with "calibrated" radiometers on the light intensity or power irradicance in mW/cm² (milliwatt per square centimeter), meaning the power in mW divided by the area of the light exposure in cm².

The radiometer, however, as "calibrated" as the manufacturers claimed, is not an accurate but a relative measurement instrument. The powers measured from radiometers are the irradiance level at the tip of a curing light, which does not inidicate the power level received by composite inside a cavity.  Additionally, readings from radiometers vary significantly from their actual values. For example, a light measured on Kerr LED radiometer for 800 mW/cm² displays 1066 mW/cm² on Cure Rite, and 1280 mW/cm² on Radii Radiometer as demonstrated by BlueLight Analytics, who has developed a highly accurate system called MARC that measures light intensity at all distances based on NIST calibrated spectrometer.

FUSION Curing Lights are measured using both common radiometer and a precision NIST calibrated spectrometer system to ensure each production unit meets the criteria in our specifications. Because of the low dispersion from the patented FUSION lens system, you can be assured that FUSION delivers similar energy for both anterior and posterior standard restorations and more energy to bonding brackets than other LED lights on the market.

a)       FUSION parts are recommended to be cleaned and disinfected with a cleaning solution including Cavicide, Lysol, Isopropyl or Ethyl alcohol. Do not autoclave or ultrasonic.

b)       Thoroughly wipe clean handpiece, Charging Base and Eyeshield with a soft cloth or tissue damped with the cleaning solution. Do not spray or soak. Disinfecting agents and liquid must not enter any openings on unit in particular Metal keypad.

c)       Clean curing lens and electrical metal contacts using Q-tips slightly damped (do not soak) with the cleaning solution.

Safeguard handpiece opening area, metal keypad, charging plug, and lens against liquid and sharp objects as this may cause electrical short-circuit, permanent optical damage or malfunction

Yes. With FUSION, you have the options of upgrading to full DOE or starter DOE, while the latter enables you to perform soft tissue oral exam and composite removal procedures at more than half the price of the competitors.

The DOE full kit comes with a White Light Head for oral illumination and transillumination. FUSION curing light can optionally add-on White Light Head. It accomplishes two goals:

• Illumination to have side-by-side visual under fluorescence and enhanced white light illumination with the same magnification image
• Transillumination for hard tissue oral health exam including dental caries, fractures, and root canal.

The Exam Tip (also doubles as a Tacking Tip for veneers/crowns/brackets with curing light head) is a disposable black 3mm opening tip that adapts and snaps into the end of the light head to cut down side light emission and guide the light propagation into a focused filament of light. It enables transillumination into interproximal teeth and improves contrast of visual exams on anterior, posterior and endo root canal.

Every day in US, half of a million white filling restorations are performed using curing lights. Studies have shown that the average lifetimes of the fillings are only 5.7 years, far from what they should be due to improper cure since every curing light is different in terms of energy dosage they can deliver with a given time, in particular in a filling pocket deep from the top surface.

Most LED curing lights on the market today have an irradiance (intensity or power density) value below 1000 mW/cm2 while a lot of them significantly overclaim their power using artificially inflated radiometer. FDA guidelines require a minimum of 300 mW/cm2 for proper cure.

High power and rapid curing lights are highly desirable since the composite hardness and curing time are directly tied to the local irradiance. Therefore, uniform and high irradiance level are highly desirable for composite cure. Uncured composite results in tooth sensitivity, microleakage and increased wear of the composite that influence the success rate of a restoration or the result of a bonding failure.

Aside from power or energy distribution, curing lights vary significantly in terms of their ergonomics, cordless vs. corded, functionality, wavelength and more importantly their quality and service/support.

As the second most used clinical equipment, curing light selection is critical to the daily clinical operation and work flow.

Yes. FUSION is a handful of LED Curing Lights that cures all materials. It uses a smart patent-pending interchangeable 360 degree swivel LED light head that accommodates standard LED and violet LED enabling it to cure all dental composites.

Legacy halogen or older version LED curing lights cure in 20-30 seconds or more. Recent advances in high-intensity curing lights offer several advantages over lower-intensity lights. Two of the most important advantages for most dentists are time savings and a reduction in
frustration.

Dr. Gordon Christensen recommended FUSION as one of a few high intensity curing lights that could save about $26,399 per year in a typical general practice for just time savings alone. It is a no brainer to upgrade your old curing lights to the new high power LED curing lights.

In general, higher intensity curing light generates more heat. Common test of an LED curing light by pointing it to the finger and feeling how hot it gets from the light tip tells you the power and quality of a light. The higher the optical power, the hotter it is going to feel on your finger from optical absorption of your skin. If it does not feel anything on your finger right away, it is a low power LED light. A simple test using FUSION in half-power mode with expanded beam lens proves the above statement. You will not feel much on your finger but it is working at 800mW/cm2 with large dispersion.

There are several techniques to manage heat from high intensity curing lights including
FUSION:

• Use appropriate curing times. Limit the exposure time on a single tooth to below 10 seconds at a time, which has proven to be safe.
• Do not place light in direct contact with unprotected gingival, oral mucous membrane or skin. Prevent heat accumulation with a rubber dam in place or apply Kool-Dam on the gingiva and surrounding soft tissue prior to curing.
• Use technique of blowing air from an air syringe on the tooth being restored at the
  same time the resin is being cured as suggested by Dr. Gordon Christensen.
• Use technique of placing a wet cotton roll directly on the tooth crown opposite the side of exposure to lesson temperature rise.
• Use Standard LED Power (Half Power) Mode to generate minimum heat.

FUSION uses the most efficient passive cooling technology from aircraft aluminum as heat dissipater for LED. Since light curing happens in short durations different from constant power sources such as computers, passive cooling without a fan is not only sufficient to ensure optimum performance without the annoying fan noise but also extends product lifetimes as is proven in the field for years. FUSION has a typical continuous run time of over 4 minutes before
self thermal protection and shutdown in High Power Mode. Considering the extreme high intensity and perfect beam quality from FUSION light tip, typical composite curing time is just 5-10 seconds. The heat concern should not be an issue in normal clinical use.

Press Unit Power Key during operation to switch to Standard LED Power mode (800mW/cm2). Use this power mode to avoid heat. The matter of fact is, since FUSION is so much advanced and powerful, that the Half Power Mode is higher than or equal to actual power outputs of other leading brand LED curing lights with a similar tip size. For example, Demi with 11mm Turbo tip outputs 800mW/cm2 power*. With its advanced heat cooling and power maintenance technology, FUSION generates minimum heat in Half Power mode and allows continuous operation without any interruptions.
