Dental posture: Guidelines + Tips & Photo's!

As a dentist and or assistant you often experience strain and musculoskeletal issues. This can possibly lead to early retirement.

This issue can be resolved by correcting posture while treating patients.

In this article we will share a few guidelines. By following these guidelines, you as a dentists or dental assistant can avoid strain and musculoskeletal issues, ensuring safer working practices.

What are the postural problems in dentistry?

Dental professionals are required to maintain static postures for extended periods of time, which can lead to discomfort and musculoskeletal issues.

This is especially true when performing clinical work, as dentists and their assistants may need to bend forward and repeatedly rotate their head, neck, and trunk to one side.

Such awkward postures can cause strain on the body and increase the risk of injury.

10 O'clock position

Holding the 10 o'clock position while working can cause discomfort and pain in the shoulder, arm, and hand muscles, as it requires the dentist to raise their arms above the patient's head and lean to one side.

The optimal posture for preventing such issues is the 12 o'clock position, where the arms are not elevated, and the dentist can comfortably situate themselves above the patient's head.

It's important to note that the 11-12 o'clock position allows for performing 70% of dental treatments.

Sitting Too Low

Sitting on a flat seat pan with thighs parallel to the floor rolls the pelvis backward and flattens the natural curve of the lower back. This flattening can have adverse effects on the spinal musculature and the discs.

To prevent muscle strain, disc pressure, and low back pain, the hips should be higher than the knees.

Adjusting the operator stool to a higher level, where the thighs slope more steeply downward, can help maintain the natural curvature of the lower back by positioning the hips higher than the knees.

TTL Loupes

Maintaining a forward head posture of over 20 degrees can cause significant neck pain. However, using through-the-lens (TTL) loupes restricts the dentist's ability to maintain a safe head posture.

Additionally, employing long barrel (high magnification) scopes attached to TTL frames can increase pressure on the cervical spine and lead to severe neck pain and dysfunction.

To maintain an optimal head posture angle of less than 20 degrees, dentists should use appropriate loupes.

Why is posture important in dentistry?

The significance of posture in dentistry cannot be overstated.

Dental ergonomics emphasizes the importance of maintaining a natural and comfortable posture for dentists to prevent musculoskeletal problems.

This, in turn, helps in providing patient-friendly treatment, enhancing treatment efficiency, and achieving treatment accuracy.

  • Keep both feet flat on the ground and upper board of the thigh slightly bent.
  • Keep your back straight and shoulders horizontal.
  • Sit more on the edge of your seat to encourage good posture.
  • Move around the patient's head to get a better view of the oral cavity.
  • Use different positions to view the oral cavity from different angles.
  • Make sure the nursing chair is about 10 centimeters higher than the operator's chair.

Proper sitting techniques for dental assistants

Having the proper sitting technique is crucial for dental assistants. By positioning themselves correctly on the dental assistant stool, they can:

  • Reduce fatigue.
  • Improve visibility of the dental field.
  • and easily access the necessary materials during procedures.

A dental stool is designed with simple and straightforward parts that provide comfort, stability, and mobility while working.

The covering of a dental stool should be durable and easy to disinfect between patients. The abdominal bar of a dental stool should be adjusted to provide either back or abdominal support, while a foot bar at the base should offer additional support.

Adjusting the height positioning lever under the seat allows for improved visibility, with the dental assistant sitting about four to six inches taller than the dentist.

Good posture is also essential for comfort and efficiency, especially during lengthy procedures where the dental assistant may be in a fixed position. In these cases, a mobile cart can be used to hold various instruments and materials.

When positioned correctly on the stool, dental assistants are ready to work smoothly and efficiently alongside the dentist.
