What is Easy Check
For every operating style
Ergonomic solutions that make the most of versatility
Equipped with a dentist’s module that can be positioned anywhere around the treatment area, the Hybrid model features an assistant’s module that can be shifted right or left, always remaining independent from dentist module rotation. Exceptional operating freedom whether working alone or with an assistant.
To complete module conversion where the unit is configured for left-handed dentists, the S220TR Hybrid has a repositionable instrument control panel: just detach it, rotate the quick coupling 180 and then reposition the panel on the opposite side of the module.
The S220TR Hybrid is suitable for all surgeries, even where spaces are narrow, and is available in the Continental version only.


Everything within reach to optimise organisation and productivity
Thanks to the broader arm system on the hanging-tube instruments model, the dentist’s module can reach all the usual working positions around the patient.
Made of light cast aluminium, the fixed arm can pass over the patient whatever the situation. A broad handle running the full width of the module makes module movement even easier. The handle can be removed for cleaning purposes.
When placed in their holders, instruments are supported securely and arranged diagonally to optimise ergonomics. The syringe is positioned vertically at the start of the handpiece holder, ensuring a good grip. A large easy-to-read LCD touch screen is positioned above the instruments.
Dentists can control patient chair movements, hygiene systems and other integrated devices.
Where the i-XS4 micromotor is present the instrument control panel also provides a full complement of endodontic functions (including control of the apex locator, with data display during canal treatment).

Arms, modules and instruments that ensure working flexibility and comfort
Everything on the Continental model has been designed to provide the dentist with an extremely flexible system. From the compactness and lightness of the dentist’s module to the swing joints that allow instrument levers to move laterally without causing wrist fatigue, every single ergonomic aspect is designed to optimise mobility.
The dentist’s module is light and compact. Instruments are easy to use thanks to generous tubing excursion and a tubing recovery arm system minimises interference with the operating light. The handle incorporates a pushbutton to release the pneumatic lock on the module, helping the dentist position it perfectly after vertical adjustment.
All this ensures the dentist can always count on perfectly positioned instruments and, therefore, maximum working comfort.
Endodontics at your fingertips

SC Scalers
Ultrasound scalers, compatible with the best commercially available tips, for supragingival prophylaxis and periodontal tasks. Also suitable for the preparation of small cavities and usable in endodontic root canal cleaning techniques. Available with or without LED lighting.

Micromotor i-XS4
Supplied as an alternative to the i-XR3 LED micromotor, the i-XS4 is suitable for conservative, prosthetic and endodontic dentistry. Speed ranges from 100 to 40,000 rpm and torque is adjustable. Powerful, light and versatile, it features autoforward and auto-reverse functions and is fully autoclavable.

Apex locator
With the dedicated contra angle, the apex locator allows the apex distance to be displayed during the root canal instrumentation phase. The nearing of the apex is also indicated by a warning buzzer; to enhance safety, micromotor rotation is automatically disabled when it is reached.

EVO E4 contra angle
Featuring a 4:1 ratio specific for endodontics, the EVO E4 contra angle can be autoclaved and heat disinfected. The miniaturised head makes access to the treatment zone easier. Recommended where the integrated apex locator is used.
Sharing information reassures patients and aids cooperation
Coupled with a latest-generation HD video camera, the Full HD 16: 9 tilt-adjustable 1920 x 1080 pixel flat screen medical monitor can be lead-connected to a PC. LED light sources ensure high levels of contrast and brightness while, thanks to the IPS panel which significantly broadens the screen viewing range, images can be viewed comfortably from any angle.


Unified in a single area, the system features cuttingedge X-ray devices
Integrating a complete system boosts diagnostic potential while shortening treatment times. Featuring advanced technology, the system includes the X-ray unit with digital wireless handheld controller, a LED monitor with optional touch-screen function and a latest generation digital sensor. X-ray images can be displayed in a matter of seconds on the 22” monitor, letting dentists share information with patients immediately before deciding on a treatment plan.

Advanced lighting and controls
From operating light to foot controls, personal preferences matter

The Venus Plus operating light rotates on three axes and puts out a light intensity ranging from 8,000 to 35,000 Lux. The potentiometer-adjusted light features a soft-start function and has a colour temperature of 4900K.

The Venus Plus – L LED, with light intensity from 3,000 to 50,000 Lux and a colour temperature of 5000K, incorporates a no-touch sensor for adjustment via potentiometer

The high-end Venus LED MCT option has a Colour Rendering Index (CRI) of over 95, a factor that allows ultra-high colour fidelity. It’s also possible to use 3 colour temperatures so users can select the right lighting for their specific clinical disciplines: 4300K warm light for surgical treatment; 5000K neutral light for conservative work; 5500 K cool light for realistic colour capture

Multi-function foot control Cutting-edge device with ergonomic lateral-slide control that lets dentists activate Chip Air and Chip Water functions on the instrument in use, invert micromotor rotation (when extracted), control patient chair movement and recall saved positions. Cabled and wireless versions available.

Pressure-operated foot control Offering the same performance as the multi-function foot control, this unit offers different ergonomics for those who prefer a pressure-operated approach. Cabled and wireless versions available.

Power Pedal This third foot control model offers different design and ergonomics. It provides the same functions as the more classic models. Cabled and wireless versions available.
