2. Crossbite refers to a condition were one
or more teeth may be abnormally malposed
buccally or lingually or labially with reference
to the opposing tooth or teeth.(Graber).Its also
called as ‘Reverse bite’ or ‘reverse overjet’.

3. Anterior Crossbite
 Single tooth
 Multiple teeth or segmental
Posterior Crossbite
 Unilateral
 Bilateral

Single tooth

 Anterior crossbite
 Posterior crossbite
 Functional crossbite

5. Anterior Crossbite: This is a condition in which one or more primary or
permanent maxillary incisors are lingual to the mandibular incisors.
Buccal Crossbite: Condition in which the maxillary posterior teeth is buccal to
the mandibular antagonist.
Lingual Crossbite: Condition in which the maxillary posterior teeth is lingual
to the mandibular antagonist.
Scissors bite or Telescopic bite: Mandibular teeth are entirely lingual to the
maxillary arch.

6. Anterior crossbite is a condition in which
one or more primary or permanent maxillary
incisor is lingual to the mandibular incisor.

7. a. Dental factors :
 A dental anterior crossbite is because of abnormal
axial inclination of the maxillary incisors.
 The reasons for abnormal axial inclination are:

Trauma to primary teeth or to the permanent tooth
bud

Over retained primary tooth

Labially positioned supernumerary tooth .

Inadequate arch length which causes lingual
eruption of permanent tooth

Lip biting habit

Repaired cleft lip

8. b. Skeletal factors :
 Skeletal crossbite results due to excessive
mandibular growth mandibular growth.
 It is genetic or inherited malocclusion.
 In children with cleft palates where there is
retrognathic maxilla.

9. c. Functional factors :
 A dental crossbite also occurs due to functional
interference of the mandible during closure.
 This is because premature tooth contact.
 This results or leads to pseudo-class III
malocclusion.

10. 




Loss of arch length as the adjacent teeth
migrates.
Excessive wear to the teeth.
Traumatic occlusion of the unlocked tooth.
Development of pseudo-class III.
Hence , all anterior crossbites should be treated
as early as possible.

12. A posterior crossbite is an abnormal
buccolingual relationship of a tooth or teeth
between maxilla and mandible when they are
brought into centric occlusion.

13. a. Dental factors:
 Faulty eruption pattern where the tooth erupts
out of position
 Insufficient arch length
 over retained primary tooth
 Ectopic eruption
 Prolonged thumb or finger sucking

14. b. Skeletal factors:
 Asymmetric growth of maxilla or mandible
due to
 Inherited growth pattern
 Trauma
 Long standing functional problem
 Difference in align width in maxilla and
mandible due to
 Constricted maxilla
 Cleft palate

15. c. Functional or muscular crossbite :
 This is due to functional adjustments to tooth
interferences
 In this condition, muscular adjustments is more
when compared to dental crossbites .
 Functional analysis has to be done.
