3. In initial stages habits are of conscious effort
gradually they become less conscious and
often become unconscious if performed
repeatedly
Frequently children acquire certain habits that
may be either temporary or permanent
Oral habits in children have a definite effect on
developing teeth and its supporting structures
5. Aetiology of malocclusion

Habits
From a clinical perspective, it is useful to classify the aetiology of malocclusion under
the following headings:
Combinations
6. Malocclusion and Age
Strongly established
During the first 3 yrs
Damage can be DETRIMENTAL
The worst amount of damage seen

7. Malocclusion and Habits
Position of the digit/pacifier etc.
Associated orofacial muscle contraction force
Mandibular position during sucking
Facial skeletal genetic pattern
Amount, frequency, & duration of force applied
The type of malocclusion produced by the habit is dependent on the following variables:
11. Includes the physiologic pacifiers like the NUK.
Nearly identical to thumb sucking
Similar clinical findings,
only not that pronounced!
Tx - throw away the pacifier!
Caution - child may
substitute missing
pacifier with a digit!

13. Thumb sucking may be practiced even in
intra-uterine life and is considered as
normal till age of 3 1/2 to 4 years.
Common habit seen in most of the children
The placement of thumb or
one or more fingers in
varying depths into the
mouth

10. Feeling of personal in adequacy
Thumb and Finger Sucking :
* Causes:
1. Prolonged suckling
2. Rooting or placing reflex of mammalian
infants
3. Feeling of insecurity
4. Child deprived of parental love and care
5. Learned pattern without any underlying
cause
16. Thumb and Finger Sucking :
Thumb sucking habit could be divided into 3 phases:
Phases
(a) Phase I: Normal Subclinically
Significant Thumb-Sucking: From birth to 3 years.
(b) Phase II: Clinically Significant Thumb-Sucking:
From 3- 7 years
(c) Phase III :Intractable Thumb- Sucking:
after 7 years

47. A major cause of anterior tongue posture is the rate of development of the tongue as
compared to the mandible.
By age 8 the tongue has reached 80-90% of its adult size. Compare this to the 50% size
of the mandible at age 8.

50. EXERCISES FOR TONGUE THRUST AND OPEN BITE
PATIENTS
An open bite describes the lack of overlap of the upper and lower front teeth.
This can have a significant consequences to chewing food, speech, and tooth
wear. An anterior tongue thrust during swallowing is usually seen in these
cases. These exercises will help retrain the tongue and help close the open
bite.
The goal is to repeat each exercise 10 times, and do these exercises 4 times
per day. The exercises should take a few minutes to do.
1. Clicking
2. Slurp; Squeeze: & Swallow
3. Squeeze teeth together thorough the day
4. Drink fluids after meals
5. Chew gum 1hour per day (sugarless)with lips together

52. -Various muscle exercises of the tongue are
carried to adapt the new swallowing pattern
-After the habit is intercepted the malocclusion
is treated using fixed or removable appliances.
- The mode of respiration
influences the posture of the jaw ,the tongue
and to a lesser extent the head
- Thus mouth breathing leads to altered jaw
and tongue posture and malocclusion
53. -Various muscle exercises of the tongue are
carried to adapt the new swallowing pattern
-After the habit is intercepted the malocclusion
is treated using fixed or removable appliances.
1.Normal people indulge in mouth
breathing under physical exertion such as
during strenuous exercise or Sports Activity
2.Complete or partial Obstruction of nasal
passage like deviated septum, nasal polyps,
tumors or adenoids can result in obstructive
mouth breathing
CAUSES
54. -Various muscle exercises of the tongue are
carried to adapt the new swallowing pattern
-After the habit is intercepted the malocclusion
is treated using fixed or removable appliances.
3.Habitual mouth breathing can be seen
as a unconscious deep rooted habit in
few people even after the removal of
nasal obstruction
4.Anatomic mouth breathing can be
seen in people with Short upper lip or
incomplete closure of mouth
CAUSES
55. Mouth breathing
Functional causes of malocclusion
! Large adenoids.
! Diseased tonsil e.g. tonsillitis.
! Hypertrophy of nasal turbinate.
! Nasal deformity e.g. deflected nasal septum.
! Hypertrophy of lymphoid tissue in
the nasopharynx.
! High fever.
Pathological mouth breathing
* Types of Mouth Breathing:
Habitual mouth breathing
56.
57. -Various muscle exercises of the tongue are
carried to adapt the new swallowing pattern
-After the habit is intercepted the malocclusion
is treated using fixed or removable appliances.
1.Long and narrow face.
2.Narrow nose and nasal passage.
3.Short and flaccid upper lip.
4.Contracted upper arch.
5.An expressionless or blank face.
6.Increased overjet.
7.Anterior marginal gingivitis.
8.Dryness of mouth predisposes to
caries.
9.Anterior open bite.
EFFECTS
58. Mouth breathing
The effect of mouth breathing in producing malocclusion is explained as
Mouth breathing
Alters the posture of tongue, jaws & head
Tongue occupies a low posture, mandible drops & head tips back
This alters the equilibrium of pressure to jaw & teeth
Forces from buccinator mechanism is not counteracted
Cause adenoid faces or long face syndrome
59. Mouth breathing
Features of ADENOID FACES or long face syndrome
1. Increased overjet
2. Increased facial height
3. Narrow maxillary arch
4. Supraeruption of posterior teeth
5. Mandible rotates downward & backward
6. Open bite
7. Gingival and periodontal disease
8. Posterior cross-bite

61. -Various muscle exercises of the tongue are
carried to adapt the new swallowing pattern
-After the habit is intercepted the malocclusion
is treated using fixed or removable appliances.
-Referring to ENT surgeon for the
removal of nasal or pharyngeal
obstruction.
-Interception of the habit by using
Vestibular screens.
-Adhesive tapes can be used to establish
lip seal
-Rapid maxillary expansion procedures
are used to widen the constricted palate.

65. 1.Psychological and emotional stress
2.Occlusal interference or discrepancy
3.Pericoronitis and periodontal pain
CAUSES
66. 1. Occlusal wear facets on teeth.
2.Fractures of teeth and restorations.
3.Mobility of teeth.
4.Tendreness and hypertrophy of masticatory
muscles.
5.Muscle pain when patient wake up in the
morning.
6.TMJ pain and discomfort.
EFFECTS
67. -Many cases of bruxism are involved with
emotional and psychological disturbances
,thus Psychological Counselling is
initiated.
-Hypnosis, relaxing exercises and massage
can help in relieving muscle tension.
-Night guards or Occlusal splints are
covered to prevent wear and occlusal
prematurities.

70. Treatment Options
Accurate assessment in context of the child’s physiologic and psychologic state
Proper and effective management
Dentist-Patient Discussion
Reminder Therapy
Reward System
Appliance Therapy
71. Dentist-Patient Discussion
Straight-forward discussion
Express concern and explain why the habit should be dropped.
Encourage them to call the office and speak to you if the habit urge
returns.
Parents can help monitor only.
72. Reminder Therapy
Reminder and not a punishment!
⌧Adhesive bandage
⌧Cotton glove
⌧Fingernail polish
⌧Bitters
⌧Arm wraps
وليس تذكيرعقاب!
73. Reward System
Consult parents to find out what
are the child’s likes and what prizes
are suitable and special to the child.
Above the age of 5 yrs, use self
esteem rewards.
Formulate a contract between the
child and parent for a short period
of time (1-2 weeks).
Greater the involvement of the
parent and child, the more
successful the outcome.
Highly recommended as it is effective.
75. Finger Sucking Appliances
Palatal Crib
Habit Correcting Appliances
Orthodontists commonly use a
“crib” to break the chronic tongue
thrust. This appliance serves only as
a reminder to keep the tongue back.
This in combination with “tongue
exercises” has shown to help reduce
an anterior open bite.
80. Summary
Abnormal habits typically interfere with regular
facial development.
The longer a habit is practiced, the harder it is
to break.
Duration, frequency and intensity play
important roles in the permanency of the
damage seen.
When considering treatment, make sure the
child wants to break the habit.
Placing fixed appliances should be the last
resort for habit cessation.
