This document discusses the management of cross bites in dentistry. It defines cross bites as abnormal occlusions where one or more teeth are positioned lingually or labially in relation to opposing teeth. Cross bites can be classified as anterior, posterior, skeletal, dental or functional. Management depends on the dentition stage and includes techniques like occlusal grinding, arch expansion appliances, and orthodontic tools like elastics or springs. Expansion appliances discussed include quad helix, rapid palatal expander, and hybrid designs. Surgical correction may be used for severe cross bites. The goal is to properly diagnose the cross bite type and address it at early detection for best treatment outcomes.
Frankles appliance Is a myofunctional appliance
Functional appliance are removable or fixed appliances that aim to utilize eliminate or guide the forces arising from muscle function,tooth eruption and growth inorder to alter skeletal and dental relationship
Buccolingual malrelationship of upper and lower
teeth.Anterior or posterior (unilateral or bilateral) with or
without mandibular displacement.
Buccal crossbite: Lower teeth occlude buccal to
corresponding upper teeth .
Lingual crossbite (scissors bite): Lower teeth occlude
lingual to palatal cusps of upper teeth.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2. Introduction
• Crossbites are term used to describe
abnormal occlusion in transverse plane. The
term is also used to describe reverse overjet
of one or more anterior teeth.
www.indiandentalacademy.com
3. Definition
• GRABER has defined cross bites as a
condition where one or more teeth may be
abnormally malposed buccally or lingually
or labially with reference to opposing tooth
or teeth.
www.indiandentalacademy.com
4. Classification.
• Based on their location as:
Anterior :single tooth or segmental
Posterior:unilateral or bilateral
• Based on the nature of the cross bites
Skeletal
Dental
Functional
www.indiandentalacademy.com
5. Etiology
• Persistance of a deciduous tooth
• Crowding or abnormal displacement of one
or more teeth
• Retarded development of maxilla in sagittal
as well as traneverse direction
• Narrow upper arch
• Collapse of the upper arch
• Unilateral hypo or hyper plastic growth of
any jaws
www.indiandentalacademy.com
6. Contd
• Sagittal discrepancies of the jaws such as
forwardly positioned mandible.
• Presence of habits such as thumb sucking
and mouth breathing can cause lowered
tongue position.
www.indiandentalacademy.com
7. Classification by the
characteristics of mal occlusion
• Evaluation of facial proportion &esthetics
• Evaluation of allignment &symmetry
• Evaluation of skeletal&dental relationship
in the transverse plane of space.
• Evaluation of skeletal&dental in the
anterior plane of space
www.indiandentalacademy.com
8. Management
• Management of dental cross bite
• management of skeletal cross bite
• DENTAL CROSS BITE management in
• primary dentition
• early mixed dentition
• late mixed dentition
• permanentdentition
www.indiandentalacademy.com
9. Management
• SKELETAL COSS BITE management in
• pre adolescent children-primary &early
mixed dentition. 2.Palatal expansion in late
mixed dentition
• Adults
• SURGICAL correction
www.indiandentalacademy.com
10. Management in the primary
dentition
• Anterior cross bite: removing the
interferences by occlusal grinding or
extracting the primary incisor.
• Posterior cross bite: if the inter molar width
is satisfactory, grinding primary canines to
eliminate deflective contact. If both molar
&canine width are narrow, expansion of the
upper arch is indicated.
www.indiandentalacademy.com
11. Early mixed dentition period
• ACB: Lingually trapped inciors can be
corrected by extracting the adjacent canines
if sufficient space is not available. If
sufficient space is available a maxillary
removable appliance is usually the best
mechanism to correct a simple anterior
cross bite that requires tipping movement.
www.indiandentalacademy.com
12. contd
• PCB: Both removable & fixed appliance is
used. The maxillary arch should be over
expanded and then held passively in this
over expanded position for approximately
3months before it is removed.
www.indiandentalacademy.com
13. Contd
• 3 basic approaches to the treatment of PCB
in children
• equilibration to eliminate mandibular shift
• expansion of the constricted maxillary arch
• re positioning of individual teeth to deal
with intra arch asymmetries.
www.indiandentalacademy.com
14. History of expansion appliance
• 1875 Coffin found the coffin spring
• 1902 Pierre Robin introduced jack screw
• 1924 maxillary crozat appliance by HC
Pollack
• 1947 Rickets introduced the quad helix
• 1960 RPE by Angell
• 1993 nickel titanium palatal expander
byWendell.v .Ardntwww.indiandentalacademy.com
15. COFFIN SPRING
• Made of 1.25 mm SS wire
• differential expansion in molar & pre molar
regions.
• Disadvantages: unstable ,lack control in the
molars,frequent activation needed , force
applied varies.
www.indiandentalacademy.com
16. W- Arch
• Constructed of 36 mil steel wire soldered to
molar bands
• move both primary &permanent teeth
&accelerate the rate of normal expansion of
the mid palatal suture.
• Activated by simply opening the apices of
W
• Expansion should continue at the rate of
2mm per monthwww.indiandentalacademy.com
17. Quad helix
• Constructed with 38 mil steel wire
• Helices in the anterior plate helps in
stopping a sucking habit.
• Indicated for the correction of crossbite &
finger sucking habit.
• Forces are produced when the appliance is
widened by 3to 8 mm
• 3 months of retention is recommended
www.indiandentalacademy.com
18. Indications
• Crossbites in which upper arch need to be
widened
• thumb sucking or tongue thrusting cases
• cleft palate conditions either unilateral or
bilateral
• cases of class 2 & class 3 conditions in
which the upper arch need to be widened.
www.indiandentalacademy.com
19. Disadvantages
• Excessive tipping of teeth buccally
• movement are not long enough & hence not
retained long enough.
• Restriction of tongue space so tongue
function is hampered
• intermittent forces
• frequent activations are required
• uncomfortable for patientwww.indiandentalacademy.com
20. Cross elastics
• Typically run from lingual of upper molar
to buccal of lower . For scissors bite
opposite is followed.
• Indicated for a short period to correct
simple cross bite
• effective in correction of unilateral cross
bites.
www.indiandentalacademy.com
21. NITI palatal expander
• It is a tandem loop ,temperature activated
palatal expander.
• Apply light continuous pressure on the mid
palatal suture.
• Self activated
• action is due to niti’s shape memory
&transition temperature effects
www.indiandentalacademy.com
22. Advantages
• Little clinical manipulation
• absence of lab work
• reduced treatment time
• exerts light continuous forces
• requires no adjustments
• comfortable & minimal patient co operation
• it has a safety system &helps the patient to
mitigate the pressure responsewww.indiandentalacademy.com
23. ELSAA
• Expansion & Labial Segment Alignment
Appliance
• used for the purpose of expansion and labial
segment alignment prior to treatment by
functional appliance
• until 4-6 months into the functional
treatment ,the previous ELSAA must be
worn when ever the functional appliance is
out of mouth. www.indiandentalacademy.com
24. Eccentric screws
• For fanwise maxillary expansion
• Consists of two parts - hinge & special
screw
• Types -
1. Wipla expansoion screw
2. G mullers anterior & posterior fan wise
expansion
3. Screws meant for pressure on single teethwww.indiandentalacademy.com
25. Disadvantages
• Only outward tipping of teeth
• patient cooperation is essential
• force levels decline especially if patient is
not activating properly
www.indiandentalacademy.com
26. Hybrid expanders
• Hilger’s palatal expander- James .J.Hilger-
1991
• rigid midpalatal dysjunction ( nance button
& screw) with flexible( Quad helix)
alveolar tipping type of appliance.
www.indiandentalacademy.com
27. Slow expansion screw
• Introduced by FARRAR
• Piere robin introduced the jack screw & was
incorporated by A.M Schwartz in 1930
• equal division of the plates will provide
reciprocal anchorage
• screw when turned 90degre will drive the
parts of the plate apart by .2mm
www.indiandentalacademy.com
28. Types of screws
• 240 types are available
• some of them are ; 1. Wiese screws
• 2.Pullscrew
• 3. HAUSER spring action screw
• 4.3d screw of Bertoni
www.indiandentalacademy.com
29. Magnetic expansion
• Types ;Platinum cobalt
• Al-Ni-Co
• Ferrite
• Cr-Co- Fe
• Samarium Cobalt
• Neodymium-Iron-boron
www.indiandentalacademy.com
30. contd
• Studies were conducted by Vardimon et al
on female macaca facicularis monkeys
• magnetic expansion from tooth banded or
pallatally pinned appliance delivered ideal
forces compared to jack screw appliance
• Daredilier et al used mid palatal repelling
magnets expansion device to produce both
dental &skeletal changes
www.indiandentalacademy.com
31. Advantage
• Minimum patient cooperation
• less pain &discomfort
• continuous force exerted
• treatment time reduced
• less periodontal disturbances,root resorption
&caries
• no friction
www.indiandentalacademy.com
32. contd
• Less chair side time
• better force
• better directional force control
www.indiandentalacademy.com
33. Disadvantage
• Suffer tarnish &corrosion which is
cytotoxic
• cost
• bitterness.
• Bulk of magnet in space limiting
application
• bio effects of static magnetic field
www.indiandentalacademy.com
34. Management in late mixed
dentition period
• ACB- best method for tipping maxillary &
mandibular teeth out of cross bite is using
finger spring, double helical cantilever ,Z
spring along with an anterior bite plate to
prevent any hindrance to tooth movement
• Fixed appliances are also used for the
correction. Eg maxillary lingual arch with
finger springs.Use of posterior bands
&anterior bonded attachments with a roundwww.indiandentalacademy.com
35. Skeletal cross bite correction in
Pre-Adolescent children
• Corrected by opening the mid palatal suture
• Growth at this suture continues in most
children until late teens & then ceases
• less force is required to open the suture in
primary &early mixed dentition period
• W-ARCH ,Quad Helix & Jack screw
appliance are used .They deliver less than 2
pounds of force.
www.indiandentalacademy.com
36. contd
• A fixed banded or bonded jack screw appl
can be used.
• Advantages ; 1. One can apply heavy force
if needed. 2.Extinguish habit by the virtue
of appliance bulk. 3.Control vertical growth
and posterior eruption if the occlusal
surface are with bite blocks
www.indiandentalacademy.com
37. Functional Appliance
• These appliance incorporate some
components to expand the maxillary
arch,either intrinsic force-generating
mechanism like springs & jack screws or
buccal sheilds to relieve buccal soft tissue
pressure.
www.indiandentalacademy.com
38. Expansion in late mixed dentition
• As age increases, the sutures becomes more
& more tightly interdigitated and opening it
becomes eventually difficult.Avery heavy
force is required to open the suture.10 - 20
pounds of pressure.
• A fixed appliance is required because the
force magnitude is large enough to displace
removable appliance.
www.indiandentalacademy.com
39. Rapid Palatal Expander
• It involves appliance activation of at least
0.5 mm daily
• The force is transmitted immediately to the
teeth & then to the suture.
• 10 -20 pounds of pressure is applied
• the expansion occurs faster & to a greater
extent in the anterior portion of the palate
because of the buttressing effect of the other
maxillary structures in the posterior region.www.indiandentalacademy.com
40. A P MAXILLARY
DEFICIENCY
• Children under the age of 8 this treatment
can be accompolished with a face mask that
obtains anchorage from the forehead and
chin &exerts force on the maxilla via
elastics that attach to maxillary splint
producing tooth movement and
displacement of the maxilla
• in older children above 9 this produces
dental movement &very little skeletalwww.indiandentalacademy.com
41. contd
• Approximately 12 ounces of force is
applied for 14 hours per day
• elastics should be fastened to the splint
between the canine &primary first molar
area
• Ideal patient are: normally positioned or
retrusive incisors,but not protrusive.Normal
or short, but not long, anterior facial vertical
dimensions www.indiandentalacademy.com
42. Mandibular Excess
• Extra oral force applied via chin cup
restrain excessive growth of the mandible
• Two ways to use chin cup :
• First is to apply force on a line directly

46. Conclusion
• Diagnosis is the golden key to success. A
case of cross bite can be deceptive . So,it is
always mandatory to think before we leap
into conclusion, whether it is cross bite of a
true nature or pseudo. To achieve better
treatment finish,crossbites should be dealt
as soon as detected & the choice of
armamentarium can be left to clinicians
discretion www.indiandentalacademy.com
