Key Features
Unique target assist for precision curing
There are many factors that must be considered when light curing to ensure quality and durability of the restoration. Operator technique is critical and a light source must be held close and perpendicular to a restoration to avoid incomplete polymerization1. Radii Xpert’s unique target assist technology enables the correct positioning of light at the right angulation before curing. By activating the positioning light and releasing once over the tooth, curing only begins when the light is in position and the restoration receives a complete cure. Where many other curing lights compensate for poor operator technique, target assist continually improves it.

Optimally collimated beam
Radii Xpert is the ideal choice for restorations of all sizes, including bulk fill restorations that require a deep cure. The collimated beam ensures light intensity is maintained on the restoration being cured. Achieve a predictable cure, every time with Radii Xpert.
Consistent light intensity
Radii Xpert has better performance due to the light intensity remaining consistent over clinically relevant distances.
The consistent intensity ensures light will penetrate the underlying restorative with limited drop off, giving you the confidence of a full cure to the depth of a restoration.

Smart technology for ease of use
Efficiency and productivity go hand in hand. Smart technology incorporated into the Radii Xpert improves the efficiency of a dental appointment. A LCD display with countdown timer eliminates estimation and provides accuracy during a curing cycle. A favourite curing setting can be saved and multi-coloured status rings offer a visual display of curing mode, charge level and attachment type. Interchangeable full arch bleaching, diagnostic and orthodontic attachments are available with the Radii Xpert.
Ergonomically well-balanced grip
Radii Xpert’s ergonomic design allows you to comfortably access all restoration sites. The 360-degree rotatable head enables restorations in all quadrants to be accessed easily. Radii Xpert has a well-balanced slimline design and can be held in a pencil or pistol grip, minimising hand and arm fatigue.
Cures all composites
Radii Xpert will cure all commercially available composites without the need for a polywave light. The light intensity of 1500 mW/cm2* over a 4-mm aperture covers a wavelength range between 440 nm – 480 nm.
Radii Xpert delivers the right spectral distribution without the need for extended wavelengths, giving you a reliable cure for all composites, including those with Camphorquinone and Ivocerin®~.

Consistent beam profile
Restorations can be cured with the confidence of a uniform beam profile using Radii Xpert. The beam delivers an even energy distribution, with reduced hot and cold spot variation. The entire beam profile of a curing light is important to ensure restorations are cured evenly.

Enhanced heat management
Restorations can be cured safely with Radii Xpert. Heat sink technology is incorporated to reduce the amount of heat emission. Enhanced heat management prevents damage to pulp tissue that can be caused by excess heat3.
You can conveniently cure multiple restorations without the risk of overheating the unit. The absence of excess heat also helps to maintain the life of the LED.

Pulse Technology
Radii Xpert uses a combination of pulse technology and steady current to further reduce heat emitted onto the tooth. With multiple pulses per second, light output is maintained on the restoration being cured, without the risk of overheating.
Base with intensity indicator
Radii Xpert’s built-in intensity indicator allows light intensity to be monitored easily, without the need to purchase an additional hand held meter to assess relative change in output. Routine evaluation of a curing light is important for optimal operation2.
