In the oral healthcare equipment system, the dental chair is not an independent, complete piece of equipment; it is merely a component of a larger system.
This larger system is called the Dental Chair Unit
Common mechanical failures of dental chair units during long-term use include:
• Unsmooth chair height adjustment
• Jet-like movements during backrest adjustment
• Abnormal resistance in moving parts
• Unstable chair positioning
Hydraulic dental chairs are dental chairs that use a hydraulic system to raise, lower, and adjust the chair's position.
Electric dental chairs are currently the more widely used type of dental chair. They use a motor-driven system, along with a control panel and electronic logic, to achieve chair height adjustment, backrest adjustment, and multi-angle positioning.
From a holistic perspective, it can be understood as follows: In the core load-bearing and structural components of dental chairs, stainless steel is currently one of the most ideal, mature, and widely accepted materials.
Under standardized use and maintenance conditions, the overall lifespan of a dental chair unit is typically between 8 and 15 years. This is a generally accepted and rational reference range within the industry.
Many non-professionals simply understand a dental chair unit as a "dental chair" or "treatment chair," but in reality, a dental chair unit is not a single device, but a complete diagnostic and treatment system platform.
