BRUXISM AND ITS
TREATMENT
 DEFINITION:-
IT CAN BE DEFINED AS DIURNAL OR NOCTURNAL
PARAFUNCTIONAL ACTIVITY THAT INCLUDES
CLENCHING, BRACING, GNASHING AND
GRINDING OF THE TEETH.
ETIOLOGY:-
 Psychological and emotional stresses.
e.g.:- anxiety, anger, frustration .
 Occlusal interference or discrepancy.
 Pericoronitis and periodontal pain is said
to trigger bruxism in some individuals.
 CLINICAL FEATURES:-
 Occlusal wear facets on teeth.
 Fractures of teeth and restorations.
 CLINICAL FEATURES: Temporomandibular joint pain and discomfort.
 Mobility of teeth.
 Tenderness and hypertrophy of masticatory
muscle.
 Muscle pain when patient wakes up in the morning.
 Muscle activity becomes abnormal & also interfere
with TMJ functions.
 Bruxism causes disruption of the relationship or
alignment of the condyle , disc, and articular
surface of the temporal bone which is called an
intracapsular disorder or internal derangement of
the TMJ.
 It has been estimated that during clenching or
grinding the individual might impose a load of
over 20 g on a tooth over period 2.5 sec at a
time.
 EFFECT ON IMPLANTS: It has been associated with increased risk of
implant failure.
 Repeated lateral forces applied to the implants
can be detrimental to the osseointegration
process, especially during the early healing
period.
 It may be due to result of their clenching or
grinding.
 So bruxism to be a contraindication to implant
treatment, especially in the case of a short span
fixed partial denture or a single tooth implant.
 If implants are planned for a patient with bruxism
habit, protective measures should be employed,
such as ; Creating a narrow occlusal table
with flat angles,
Protected occlusion and the regular
use of occlusal guards.

There may be definitive history of bruxism but in
an unaware patient a number of sings help in its
detection.
Advanced attrition
Increased tooth mobility patterns
The presence of widened periodontal spaces in
radiographs
Hypertonicity of the muscles of masticationElectromyographic examination
TMJ discomfort
COMPLICATIONS
 If bruxism is not treated then in future life ,it
can lead to- jaw discords,
-damage to teeth and
- heavy headaches.
 People get warned about their condition only
after some complication arises and many times
they just neglect it.
 constant headache, sore jaws are two important
symptoms that indicate that the person is suffering
from bruxism.
 Once you get doubtful about your clenching of
teeth in night, you will need to take help from your
dentist. The dentist will examine your mouth and
jaw and will decide whether or not you suffer from
bruxism
 Obstructive sleep apnea is a condition which is
very often complicated by additional disorders or
problems. Many patients with this common sleep
disorder had a problem with severe teeth
grinding (bruxism)!
 According to a recent scientific study in Israel
 obstructive sleep apnea is even the highest risk
factor for sleep bruxism!
Treatment of bruxism
1.
The first step in the control of any parafunctional
habit must be discussion with the patient.
2.
If occlusal disharmonies are there ,then the
selective grinding may help to relieve the
parafunction.

Further dental treatment involves the use of
night-guards to limit the excessive occlusal
stress. There are basically two forms of nightguards, both of which are made in acrylic:
A.
The occlusal shield which fits ovre the occlusal
surface , incisal edges & lingual tooth convexity.

where attrition is sever or where there has been
collapse of the posterior segments so that the
freeway space is increased ,the occlusal shield
can be usefull.
B. the anterior bite plate.
where there is an obvious bruxism habit with
symptoms of muscle spasm & where the lower anterior
teeth are well supported with bone a night guard with
an anterior bite plate is extremely useful.

To relax your jaws, hold one warm cloth on
your cheeks and ears.

We can advise the patient to visit their dentist
even if they have just hint about their
clenching of teeth.
