Bluephase ® Product Training Presentation

Terminology Photoinitiator (light-initiator) – any chemical compound that decomposes into free radicals when exposed to light. Polymerization – a chemical reaction in which two or more molecules combine to form larger molecules that contain repeating structural units Intensity – The amount or degree of strength of electricity, light, heat or sound per unit area or volume Spectrum – a band of colors, as seen in a rainbow, produced by separation of the components of light by their different degrees of refraction according to wavelength

Category Overview Curing lights are the most used pieces of equipment in the office Used to convert light cure materials into a polymerized state (e.g. hardened, cured). The energy rich blue light transfers monomers into polymers by breaking down photoinitiators into radicals, causing a polymerization reaction. Unless the material has self-cure properties, a curing light is needed to complete ANY restorative procedure. Sufficient curing will depend on many factors, the most important of which are light intensity and the activation of the photoinitiators in the material.

Most Important Attributes of Curing Lights Ability to cure all materials Wavelength range (spectrum) must cover all photoinitiators used in the material to ensure proper curing Efficient energy distribution The less efficient a curing light disperses its energy, the more energy will be lost when curing at a distance or through ceramic (diffusion or light scattering) Battery backup A curing light always needs to have a backup option to account for battery malfunction or depletion

How features can affect quality of a curing light Consistent, reliable results Long term effectiveness Harder and more completely cured resins Elimination of post-operative issues  Failure due to weaker bond strength  Microleakage  Possible recurrent caries  Sensitivity

Ability to cure all materials Photoinitiators used in dentistry: Camphorquinone PPD (phenyl propanedione) Lucirin TPO Absorb at 380 – 430 nmAbsorbs at 390 – 510 nm - Composite- Composites in Bleach shades - Adhesives Customer needs Universal use!

Clarify material compatibility Most LEDs do not cure all materials - Bluephase family does! Halogen lights LEDs with Broad Spectrum LEDs without Broad Spectrum Ability to cure all materials

polywave™ cures all materials! rel. intensity 410 nm 470 nm approx. 200 mW/cm 2 approx mW/cm 2 Wavelength nm] Use of 2 different LEDs: dominant at approx. 410 nm and approx. 470 nm Exclusive semi-conductor technology of Ivoclar Vivadent Not available for competitors! Ability to cure all materials

Efficient energy distribution Indicated light intensity (e.g. 1,000 mW/cm 2 ) Decreasing light intensity with increasing distance (e.g. 700 mW/cm 2 at 5 mm distance) Observe distance between material & light

Energy distribution method will affect intensity lost at a distance, resulting in increased curing times LEDs lose a lot of intensity with distance - except Bluephase ! Efficient energy distribution

Battery backup With the Bluephase “Click & Cure” battery backup system, the handpiece can be connected with the power cord of the charging base. In case of emergency or in accordance with the working habits of the operator, the device may also be used solely as a corded light Cordless … but not without a (safety) net!

Internally vented cooling fan in Bluephase G2 and Bluephase 20i Virtually noiseless No breaks or having to wait several minutes for the light to cool even during the cementation of multiple restorations Additional features Heat management system

Use of energy-efficient LEDs in Bluephase Style; providing the same light output, their power loss is far lower than that of other LEDs. Furthermore, a large part of the handpiece is made of aluminium. Additional features Heat management system
