Designed For Today's Challenges.

The all-new Contra-Angle EVO.15 is one of a kind, simultaneously raising performance standards and revolutionizing patient safety. This promising electric handpiece combines Swiss precision with an unparalleled level of durability and ergonomics. Discover what makes the Contra-Angle EVO.15 the indispensable dental instrument, day in and day out.

Ultimate Precision for Durable Performance.

ACCURATE : High efficiency and cutting-edge technology come together on the Contra-Angle EVO.15. The new Accu-Chuck PreciPlus ™ bur-retention and rotation drive mechanism* is a perfect example of that – its vibration-canceling properties not only reduce noise interference, they also authorize perfect stability and accuracy no matter the speed and torque. Due to durability being a key contributor to performance, the Contra-Angle EVO.15 is fitted with a specially- designed rotor’s head that demonstrates significantly longer service life than conventional models.

The most advanced engineering techniques, skilled company know-how, and up to 3 years 1 of warranty put in your hands the quality and reliability our competitors have been trying to match for over 50 years.

Where Efficient Meets Easy.

PRACTICAL : The size of the Contra-Angle EVO.15 makes you forget that you are handling such a high-performance instrument. Its small, shockproof stainless steel head provides remarkable maneuverability and accessibility to third molars. As part of Bien-Air’s Micro-Series line, the handpiece’s comparatively lighter weight pushes the limits of comfort even further with more balanced manipulation and reduced hand and wrist fatigue.

To maximize user experience, every aspect of the Contra-Angle EVO.15 has been carefully thought-out. The improved Accu-Spray Quattro Mix™ and its dualook™ non-dazzling multi-strand optical glass system support this statement and need to be credited for competent operative field cooling and reliable intraoral visibility.

The Confidence You Have Your Patient's Trust.

SAFE : The Contra-Angle EVO.15 expresses itself in multiple ways, and patient safety is unmistakably at the forefront. Bien-Air’s patented* CoolTouch+™ ** heat-arresting technology brings the handpiece closer to zero risk when it comes to patient burn injuries. Similarly, adverse events linked to bur slippage are prevented, thanks to an extremely efficient fastening system.

When brought together, these combined safety features make the Contra- Angle EVO.15 the safest electric handpiece ever designed.


Addressing Patient Safety in the Most Responsible Manner

In recent years, the U.S. Food and Drug Administration (FDA) along with other national public health authorities, have reported an alarming increase in patient injuries resulting from electric dental handpieces overheating during procedures.* The most severe cases have caused third-degree burns requiring reconstructive surgery, likely subjecting the practitioner to lengthy legal actions.

While overheating can be an indication of a damaged or clogged instrument, laboratory evaluations reveal that this hazard is just as prevalent in new and properly-maintained electric handpieces.

In a committed effort to promote patient safety, Bien-Air is introducing CoolTouch+™, the world’s first and only heat-arresting system proven not to exceed human body temperature.** After years of research and development, this complex proprietary technology is engaged to protect both the patient and the clinician during some of the profession’s most frequently performed procedures.

Contra-Angle EVO.15 : The Safest Electric Handpiece on the Market

In dental procedures making use of electric handpieces, the briefest contact between the instrument’s push-button and the patient’s inner-cheek causes the former to overheat, resulting in possible burn injuries. While the latter’s increasing frequency is keeping public health agencies on high alert, industry-wide safety regulations are yet to be formulated.

The all-new Contra-Angle EVO.15, equipped with Bien-Air’s CoolTouch+™ heat-arresting technology, gives dental practitioners peace of mind in all situations.
