The document discusses tongue thrusting, including its definitions, classifications, and clinical features, as well as the differences between infantile and adult swallowing mechanisms. It outlines various causes such as oral habits, neurological disturbances, and hereditary factors. Additionally, it covers diagnosis and treatment options, including tongue trainers and mechanotherapy.

 According to MOYER :
 Normal swallow
 Simple tongue thrust

8. LOGO
A. Infantile swallow :-
→ All infants thrust their
tongue while swallowing.
→ Tongue lies between the
gumpads.
→ Mandible is stabilized by
contraction of facial
muscle.
→ Disappears with eruption
of teeth & growth of
mandible

9. LOGOMechanism of infantile swallow
Infant lips closed around the
areola of the breast
Tongue protrudes to the lower
lip & forms a spoon like
closure around nipple
relaxation of the elevator
muscle of mandible
mouth is open wide
milk directed to the pharynx

10. LOGO
B. Adult swallow:-
→ As a person swallows, tip of the
tongue contacts the palatal rugae
area posterior to the maxillary
anterior teeth.
→ Midportion contacts the hard
palate & posterior aspect assumes
a 45° angulation against the
posterior pharyngeal wall to
permit the bolus of food to move
into the digestive tract.
→ facial muscle are passive.

11. LOGO2.Upper Respiratory tract infection :
→ infection such as tonsillitis, allergies ,etc.
pramote a more forward tongue posture due
to pain & discomfort.
3.Functional adaptability :
→ Tongue protrude when the incisors are missing
.

12. LOGO4.neulogical distubances :
→ Hyposensitive palate, moderate motor
disability.
5.Induced due to other oral habits :
→Thumb sucking
→when this habit created anterior open
bite, the tongue protrude between the
anterior teeth during swallowing

13. LOGO
6. Hereditary :
→ Inherited hyperactivity of orbicularis oris also lead
to tongue thrust.
7.Tongue size :
→Congenital aglossia & macroglossia can have effe
ct
on the dentition.

14. LOGOClinical features :
1.Extra oral findings
 Lip posture -
 simple tongue thrust-
1.Intra oral findings:-
→Proclined & spaced
upper incisor
→ Retroclined or proclined
lower incisor
→Anterior open bite
→Posterior cross bite
→Normal tooth contact
during swallowing
→ Tongue is thrust forward
during swallowing to
establish anterior lip seal .

16. LOGO2. Extra Oral Findings :
→ Dolicocephalic face
→ Increase lower anterior
facial height
→ Incompetent lips
→ Exression less face
→ Speech problems
→ Abnormal mentalis
muscle activity

18. LOGO
 Complex tongue thrust :
1. Features -
→ proclination of anterior teeth
→ Generalized open bite
→ Absence of temporalis muscle contriction during
swallowing
→ contraction of lip,
facial & mentalis
muscle

19. LOGO
Clinical Features
 Lateral tongue thrust
→ May be unilateral
or bilateral
→ Lateral open bite is
seen
→ Poor occlusion
→ Posterior cross bite .
