Enhancing Ergonomics and Workflow in Microdentistry
Since 1992, surgical microscopes have been an indispensable tool in my private practice. Once I became fascinated with the visual advantages provided by the microscope in my day-to-day practice, I became more aware of the shortcomings of ergonomics and occasionally made the microscope a difficult dental equipment to use.
In order to make the microscope user comfortable when using the microscope, it is necessary to minimize the muscle tension and to balance the posture between the left and right sides of the body and the arms. An ideal microscope position that can facilitate this posture must allow the operator to sit at the 12 o'clock position and allow for a sufficient extension of the microscope between the objective and the eyepiece, which is at least equal to the patient's head to the patient's mouth. Prevents the operator from bending forward to reach the eyepiece and strain at the waist. The MORA interface was developed to address the challenges listed above.
In order to get the maximum benefit from the MORA interface, the operator must sit at 12 o'clock.
Posture problems when working under microscope magnification:
1. Restricted and Posture Dependent Access: The use of a microscope for visual access to the operating area is completely dependent on the operator's posture constraints. If the eye remains on the eyepiece, the microscope cannot be placed on the outside of the operator's back and neck extensions. Any movement of the microscope will cause head and neck and upper and lower back position changes. The most practical way to use the microscope when the operator is sitting at 10 o'clock. Sitting in this position forces the operator to tilt the microscope by rotating the microscope clockwise to gain visual access to the patient's mouth and then tilt his/her head toward the right shoulder, resulting in poor posture and necked position (Taco neck position).
2. Muscle tension and pain: Suppose long-term, tense poses cannot be avoided when performing clinical dental treatment under dental instruments microscope magnification. This can cause discomfort, muscle contraction and pain. The strained visual posture position is further exacerbated due to the intense working position caused by the over-stretching of the arms holding the mouthpiece and the force required to stabilize it during use, whether as a reflector or as a retractor. This usually causes pain in the shoulders and neck.
The MORA interface provides a solution to the above problems by creating a "pose-friendly" microscope system. In order to get the maximum benefit from the MORA interface, the operator must sit at 12 o'clock. A microscope with an MORA interface and beam splitter increases the horizontal distance between the eyepiece and the major axis of the microscope body. It provides a horizontal working distance that matches the distance between the top of the head and the patient's mouth.
The MORA interface saves your neck and upper back and allows your assistant to use a common observation tube. It makes the microscope more intuitive, more efficient, and more enjoyable.
