Chair Positioning Using a Microscope

The use of a microscope in dentistry has increased during the past decade. Microscopes improve magnification of the operative field and also provides improved ergonomics, reduced eye fatigue/strain, and improved lighting at chairside. It is wise in many situations to include a microscope for the assistant.

Microscopes deliver on the promise of comfortable sit-down dentistry. Using the microscope, the dentist no longer needs to twist and bend the body to obtain good visibility. The microscope provides its own light source and is directly positioned over the oral cavity like a dental light. Essentially, the dentist sits motionless and is able to sit at the 12 o’clock position even while working with mandibular molars by learning to bring the patient closer to them instead of attempting to move their body to the patient.⁴ The assistant using a microscope along the side of the dentist can also maintain good chair positioning while being able to anticipate the next needed instrument. The dentist can adjust the patient’s head with minimal movement to improve patient positioning to improve the dentist’s operating posture.

Personal loupes also provide enhanced vision for the team. Loupes are fitted to the wearer while in the optimum ergonomic position. Should the wearer move out of an ergonomic position, the view will blur. Loupes not only magnify the view but also adds safety while reducing eye strain.
