1 Dr Shwetha S Hegde Consultant, Oral Medicine and Radiology Australian Dental Board Certified Dr Shwetha S Hegde

2  A major postural imbalance  Anterior positioning of the cervical spine  Common occupational hazard Dr Shwetha S Hegde

3  Poor posture alters spine position mandible shifts forward the upper and lower teeth misalign skull moves back on the spinal column.  If not addressed, pain and inflammation in the muscles and jaw joints will develop when the mouth opens and closes.  Forward Head Posture (FHP) is a very common postural issue, and it is estimated to occur in between 66% and 90% of the population. Dr Shwetha S Hegde

4  Mandibular posture and head posture are inversely proportional in an antero-posterior (forward- backward) plane.  Shifting the mandible backward causes the head to shift forward, and shifting the head forward causes the mandible to shift backward. Dr Shwetha S Hegde

5 FHP is strongly correlated with backward mandibular posture. TMJ disorder patients typically have both FHP and backward mandibular posture. Dr Shwetha S Hegde

6 FHP Increases passive tension in muscles of mastication Backward mandibular posture Decreased resting freeway space Protective mechanism Dr Shwetha S Hegde

7  Head and jaw posture are both controlled by a hierarchy of neuromuscular reflexes, and airway protection is top priority.  For every inch the neck goes forward there is an extra 4.5 kg of weight on the neck. Dr Shwetha S Hegde

8  FHP produces a progressive loss and then a reversal of the normal cervical curve (lordosis) of the neck Dr Shwetha S Hegde

9 Changes occurring in the curvature of the spine over time due to FHP Dr Shwetha S Hegde

10  FHP causes realignment of the curvature of the spine due shifting of the weight of the head.  The weight is distributed unevenly on the intervertebral spine causing compressive strain on the intervertebral disc  This leads to stiffness and arthritic changes in the spine  Since muscles function in groups, muscles determining posture are also affected Dr Shwetha S Hegde

11  Pain in the muscles of mastication and infrahyoid muscles  Pain in the TM joints  Change in occlusion due backward shift of the mandible Dr Shwetha S Hegde

12  Stress worsens muscle tension by a measurable decrease in muscle circulation  Brings down threshold for jaw muscle pain due to inhibition of endorphin release Dr Shwetha S Hegde

13  Attitude influences posture and resting muscle tensions in the jaw area just like it does in the rest of the body. Dr Shwetha S Hegde

14  Chronic neck pain  Headaches  Tingling and numbness in the arms and hands  Improper breathing  Poor neck posture with outward stretching of neck  Chronic fatigue Dr Shwetha S Hegde

15  Re-establishing a stable balanced resting posture for the head and the mandible.  Has mechanical and psychological components.  Mechanical component- paying attention to posture while standing, sitting sleeping etc  The psychological component involves the way your mental state affects the resting postures of your muscles and thereby also the stance you use for weight bearing. Dr Shwetha S Hegde


17  Anti inflammatory drugs  Ultrasound  TENS  Cortisone injections  Use of neck brace Dr Shwetha S Hegde

18  Neck exercises because the neck muscles are the primary determinants of head posture.  Resistance exercises to strengthen neck muscles Dr Shwetha S Hegde

19  Yoga, Tai Chi, and swimming are popular exercises which provide both stretching and strengthening.  Another way to combine strengthening with stretching is to pull oneself upward using overhead bars. Dr Shwetha S Hegde

20  Ergonomically perfect chair  A simple foam rubber mattress or a relatively hard mattress is preferable  Passive support using a pillow under the neck Dr Shwetha S Hegde

21  Make sure your computer monitor is ergonomically set up. top third of your screen is at eye-level. distance from your monitor to your eyes to should be 18 to 24 inches  Never carry heavy bags, backpacks or purses Dr Shwetha S Hegde

22  Get up and walk around every half an hour that you work at a desk, work in front of a computer or watch television.  Buy a supportive neck pillow, if you often wake up with a sore neck. Dr Shwetha S Hegde

23  People in the software field  Surgeons  Dentists  Factory/high precision workers  People with a desk job  People with sedentary lifestyle-prolonged TV watching Dr Shwetha S Hegde

24  Create awareness among the target population  Counsel them to develop better posture and eliminate parafunctional habits  Treat the symptoms Dr Shwetha S Hegde
