Its six-LED configuration produces a uniform beam that enhances visibility without glare, ensuring accurate shade distinction and improved clinical precision in every treatment.
BIO SYSTEM

This intuitive system promotes sterile workflow while enhancing concentration on the procedure. Its sturdy build and precise sensitivity offer comfort and stability, even during extended sessions.
ANTI CRUSHING SYSTEM
Safety is built into the design with the Anti-Crushing System that automatically halts chair movement when an obstacle is detected. This prevents accidental damage to instruments, accessories, or patient belongings. The mechanism ensures smooth operation with full protection, reinforcing confidence in everyday clinical use.

Its flexible adjustment ensures proper neck support and stable positioning, allowing dentists to access all quadrants efficiently while maintaining patient relaxation throughout the procedure.
SOFT SOFA UPHOLSTERY
The plush sofa-style upholstery delivers a luxurious experience to patients while ensuring durability for daily clinical use. Crafted from premium, medical-grade material, it provides a gentle touch and excellent breathability. The cushioning minimizes pressure points, making long treatments noticeably more comfortable.
FOLDABLE ARMREST
For easy patient entry and exit, the foldable armrest provides a smooth, stable motion and secure support. Its design enhances accessibility for elderly or differently-abled patients, while maintaining the chair’s sleek aesthetic. Once seated, the armrest locks firmly for a reassuring sense of stability.
ASSISTANT ARM
The assistant’s arm offers functional flexibility for efficient four-handed dentistry. With multiple holders for suction and air-water syringes, it ensures everything is within instant reach. Its swivel capability allows effortless repositioning, supporting perfect coordination between the dentist and assistant during treatments.
DEBRIS FILTER
To maintain a clean hydraulic system, the integrated debris filter captures impurities before they reach internal components. This helps prolong equipment life, ensures consistent suction performance, and reduces maintenance frequency—keeping operations smooth and uninterrupted.
SENSOR BASED BOWL RINSING
The sensor-activated rinsing system allows touch-free bowl cleaning, promoting higher hygiene and ease of operation. Simply position the cup or activate the proximity zone to initiate a smooth, controlled water flow. It’s an intelligent addition that combines technology with infection control.
ZERO BACKACHE STOOL
Engineered for superior posture support, the Zero Backache Stool keeps dental professionals comfortable through the longest procedures.
