Surely at some point you have asked yourself why there is such a wide price difference between some curing lamps and others. The price is not just related to design and the accessories for the lamp but also its functions and technical features such as weight, wavelength or output power.
Curing Lamps are used in dental clinics to polymerise resins sensitive to the light in processes of restoration and to speed up some whitening treatments. To obtains some long-lasting restorations, a proper polymerisationis indispensible and will depend on a light source with a determined strength, exposure time, on the quality of the light, the impact and the distance, as well as the energy and heat released. In the first place,as basis for the correct selectionof the curing lamp your should ask yourself the following questions:
- What output power does the curing lamp that you want produce? ¿Does this match the needs of your clinic?
- What wavelength range does it achieve? Will this serve to polymerise the composits that we always use at the clinic?
- Is this for continuous use? ¿Does the lamp release heat during polymerisation?
- What polymerisation settings does it have? Is there a gradual or fixed increase in intensity?
- Is it wireless? How long does the battery take to charge? And how long does it last?
- Is it light and does it have good ergonimic design? Will we be comfortable thoughout long treatments?
At Dentaltix we offer you some tips to help you choose the polymerization lamp that best suits your needs and we will recommend some of the best proposals that currently exist in the market. The polymerization lamps are characterized by the power output, the diameter of the guides and the amount of heat emitted. According to Ivolcar Vivadent, at least 1,000 mW/cm2 are needed to polymerize composites in 10 seconds through a dental structure in indirect restorations. However, for direct restorations, at least 400 mW/cm2 of output power is required for proper light-curing.
Curing lamps are divided into:
- Halogen curing lamps.
- Plasma arc curing lamps.
- Laser polymerisation curing lamps.
- LED curing lamps.
Plasma arc and laser lamps, despite their high light output ranging from 1400 to 2700 mW/cm2, did not succeed in the market because they generated too much heat and were expensive. The same is happening with halogen lamps, which are gradually being replaced by LED (Light Emitting Diode) because they have some advantages over halogen: they consume little energy, generate less heat and have a much longer lifespan..
LED curing lamps
In fact, the latest generation of LED lamps, both the cheapest and the most expensive, are characterised by ergonomics that benefit the user's comfort and are smaller, lighter and easier to clean.
High-end polymerisation lamps:
High-end dental lamps such as the BluePhase G2 Ivoclar polymerize in depth without damaging soft tissue thanks to their high output power. This lamp has integrated soundproof fans for continuous use and polymerizes all materials in the wavelength range 380nm to 515nm.
Another lamp that should be highlighted is the Radii Plus SDI, which does not require fans as it uses a technology of descending heat that reduces heat emission. However, the emission spectrum is less broad since it goes from 440 nm to 480 nm, so you can only polymerize materials that are in that range.
Lámparas de fotocurado de gama media/alta:
Another interesting lamp that has a mid-range price and very high-quality is the Coltolux LED which is suitable for clinics where they expect a frequent use of the curing lamp.
Lámparas de fotocurado de gama media:
Right now there are many good quality LED lamps on the market with more affordable prices ranging from 150 euros. For example, if you don't frequently use the curing lamp in your practice, you can buy a device with fewer functions that is more economical as the Led D offered by the brand DTE or the cordless lamp offered by the brand Bader. The main disadvantage of latest generation of LED lamps is the battery, as they have a limited life and replacement is expensive, beginning with 90 euros depending on the manufacturer, and have a more limited spectrum than halogen lamps.
A couple of years ago, the Kerr brand launched the Demi Ultra Kit, the LED polymerization lamp with Ultracondenser. This revolutionary condenser stores enough energy to be able to run continuously for approximately 4 minutes which is equivalent to 25 polymerizations of 10 seconds. After a complete use, it recharges in just 40 seconds without losing its efficiency, so there's no need to think about recharging the battery. In addition, thanks to its output power, which ranges from 1,100 to 1,330 mW/cm2 and a wavelength ranging from 450 to 470 nm, polymerizations can be made through a dental structure. In addition, C.U.R.E. technology (Polymerization Uniformity and Energy Reduction) keeps the lamp always cold, allowing it to be used continuously without the need for fans. Stop worrying about battery replacements and getting tangled up in your clinic cables!
Corded or Cordless?
You should also check to see if the lamp you are buying comes with cables, if it is wireless or if it is integrated in the dental chair. For example, the BluePhase Ivoclar is wireless and allows continuous operation after the battery has been discharged. The Radii Plus SDI is a cordless lamp which allows for complete freedom of movement and the battery does not constantly need to be recharged.
The radiometer is a device that measures the energy emitted by the curing units. The use of this device in your clinic is necessary to control and ensure a complete and safe polymerization. The radiometer also warns of the need to change or repair the lamp. So it is important that the lamp has a radiometer to measure the output power.
