Treatment plans are based off of:
1. TMJ assessment: ROM, muscle testing,
trigger point assessment, occlusion pattern
2. Neuromuscular therapy and muscle energy techniques
to muscles of mastication
3. 6x6x6 TMJ exercise program
4. Assessment correlation with nutrition and
lifestyle, cervical, atlas, shoulder, vision,
hearing and breathing assessments
5. Referral (if needed) to a holistic dentist
or TCM practitioner
Temporomandibular joint disorder (TMJD,
TMJ or TMD), or TMJ syndrome, is an umbrella
term covering acute or chronic inflammation of
the temporomandibular joint, which connects the
lower jaw to the skull. The disorder and resultant
dysfunction can result in significant pain and
impairment. Because the disorder transcends the
boundaries between several health-care disciplines
— in particular, dentistry, neurology, physical
therapy, and psychology — there are a variety
of quite different treatment approaches.
The temporomandibular joint is susceptible to
many of the conditions that affect other joints
in the body, including ankylosis, arthritis, trauma,
dislocations, developmental anomalies, and neoplasia.
Signs and symptoms
Signs and symptoms of temporomandibular joint
disorder vary in their presentation and can be
very complex. Often the symptoms will involve
more than one of the numerous TMJ components:
muscles, nerves, tendons, ligaments, bones, connective
tissue, and the teeth. Ear pain associated with
the swelling of proximal tissue is a symptom of
temporomandibular joint disorder.
Muscles
Disorders of the muscles of the temporomandibular
joint are the most common complaints by TMD patients.
The two major observations concerning the muscles
are pain and dysfunction. The dysfunction can
present as trismus or limitation of jaw movement
ranging from minor to severe. In milder cases,
the only representation may be joint sound such
as clicking or popping. These symptoms of TMD
are often caused by overusage of the muscles of
mastication. Common causes include chewing gum
continuously, biting habits (fingernails and pencils),
grinding habits, and clenching habits.
Most cases of TMJ, however, are not so simple.
Deep-space infections with resulting trismus or
neoplams about the joint may mimic TMJ dysfunction.
Muscle pain can sometimes be associated with trigger
points in muscle tissue. These trigger points
can be localized by digital palpation, both intraorally
and extraorally.[3] This is known as Myofascial
pain syndrome.
Any dysfunction of the muscles may cause the
teeth to occlude (bite) with each other incorrectly;if
teeth are traumatized by this, they may become
sensitive, demonstrating one of the many interplays
between muscle, joint, and tooth.
Temporomandibular joints
This is arguably the most complex set of joints
in the human body. Unlike typical finger or vertebral
junctions, each TMJ actually has two joints, which
allow it to both rotate and to translate (slide).
With use, it is common to see wear of both the
bone and cartilage components of it. Clicking
is common, as are popping motions and deviations
in the movements of the joint. It is considered
a TMJ disorder when pain is involved.
In a healthy joint, the surfaces in contact with
one another (bone and cartilage) do not have any
receptors to transmit the feeling of pain. The
pain therefore originates from one of the surrounding
soft tissues. When receptors from one of these
areas are triggered, the pain causes a reflex
to limit the mandible's movement. Furthermore,
inflammation of the joints can cause constant
pain, even without movement of the jaw.
Due to close proximity of the ear to the temporomandibular
joint, TMJ pain can often be confused with ear
pain.The pain may be referred in around half of
all patients and experienced as otalgia (earache).
Conversely, TMD is an important possible cause
of secondary otalgia.Treatment of TMD may then
significantly reduce symptoms of otalgia and tinnitus,
as well as atypical facial pain. Despite some
of these findings, some researchers question whether
TMD therapy can reduce symptoms in the ear, and
there is currently an ongoing debate to settle
the controversy.
The dysfunction involved is most often in regards
to the relationship between the condyle of the
mandible and the disc. The sounds produced by
this dysfunction are usually described as a "click"
or a "pop" when a single sound is heard
and as "crepitation" or "crepitus"
when there are multiple, rough sounds.
Teeth
Disorders of the teeth can contribute to TMJ dysfunction.]
Tooth mobility and tooth loss can be caused by
destruction of the supporting bone and by heavy
forces being placed on teeth. Movement of the
teeth affects how they contact one another when
the mouth closes, and the overall relationship
between the teeth, muscles, and joints can be
altered. Pulpitis, inflammation of the dental
pulp, is another symptom that may result from
excessive surface erosion.
Precipitating factors
There are many external factors that place undue
strain on the TMJ. These include but are not limited
to the following:
Over-opening the jaw beyond its range for the
individual or unusually aggressive or repetitive
sliding of the jaw sideways (laterally) or forward
(protrusive). These movements may also be due
to parafunctional habits or a malalignment of
the jaw or dentition. This may be due to:
1. Modification of the occlusal surfaces of the
teeth through dental neglect or accidental trauma.
2. Speech habits resulting in jaw thrusting.
3. Excessive gum chewing or nail biting.
4. Excessive jaw movements associated with exercise.
5. Repetitive unconscious jaw movements associated
with bruxing.
6. Size of foods eaten.
