Orthodontic treatment modalities include preventive, interceptive, and corrective orthodontics as well as orthognathic surgery. Preventive orthodontics aims to preserve normal occlusion and includes procedures such as space maintainers. Interceptive orthodontics provides early treatment of developing malocclusions through methods like serial extraction. Corrective orthodontics utilizes fixed or removable appliances to fully treat malocclusions and can include orthognathic surgery to correct severe jaw discrepancies.
crossbite management in restorative dentistryms khatib
This document discusses the management of anterior and posterior crossbites. It emphasizes the importance of a thorough analysis prior to any treatment, including evaluating the tooth-to-tooth relationships in centric relation and the impact of changing vertical dimension. For anterior crossbites, conservative approaches like occlusal equilibration, orthodontics, and restorations are preferred but orthognathic surgery may be needed for skeletal discrepancies. Posterior crossbites should also be thoroughly analyzed before correction, ensuring the teeth can disclude properly and are harmonious with surrounding structures. The goal of any treatment is to establish a stable, functional and comfortable occlusion.

Interceptive orthodontics aims to prevent potential malocclusions from progressing and includes serial extraction, correction of developing crossbites, control of habits, space regaining, and intercepting skeletal malrelations. Common space maintainers and habit breakers used are also outlined.
This document discusses obturators, which are prostheses used to close congenital or acquired openings in the hard palate. It covers the definition, history, classifications, design considerations, materials used, and objectives of obturators. Key points include that obturators aim to restore functions like speech, swallowing and chewing. They provide support, retention and stability. Design depends on the class of defect based on an established classification system. Common materials are acrylics and silicones. Proper pre-operative dental care and temporary obturators aid in postoperative healing and function.
Preventive orthodontics aims to preserve normal occlusion and prevent malocclusion. Procedures include monitoring primary dentition, extracting retained primary teeth or supernumeraries, restoring decayed teeth, and correcting habits. Space maintainers are used to preserve space when primary teeth are lost prematurely. Removable appliances allow oral hygiene, while fixed appliances require less compliance. Early intervention through procedures with or without appliances can help guide development and reduce future orthodontic needs.

This document discusses preventive orthodontics procedures including caries control, care of deciduous dentition, eliminating occlusal interference, education of patients, and space maintenance. It emphasizes the importance of prevention and early intervention to preserve the dental arch and proper eruption of permanent teeth. Space maintenance is especially important after premature loss of primary teeth to prevent drifting and maintain the dental arch width and shape until permanent teeth erupt. Removable and fixed space maintainers are commonly used depending on factors like patient cooperation and eruption status of permanent teeth.
Management of cross bite /certified fixed orthodontic courses by Indian dent...Indian dental academy
This document discusses the management of cross bites. It defines cross bites as abnormal occlusion where one or more teeth are malposed buccally, lingually or labially in relation to opposing teeth. Cross bites are classified based on location (anterior vs posterior) and etiology (skeletal, dental or functional). Treatment depends on the dentition stage and includes techniques like occlusal grinding, arch expansion appliances, and fixed appliances. Skeletal cross bites in children can be corrected using expanders to widen the maxilla, while adults may require surgery. Functional appliances can also help expand the maxilla in growing individuals.
An obturator is a prosthesis that closes congenital or acquired defects in the palate. It functions to enable speech, mastication, improve esthetics, keep the defective area clean, reshape the palatal contour, and reduce exudate flow into the mouth. Obturators are classified based on whether the defect is congenital or acquired, and can include variants like inflatable bulbs or magnets. The case report details the 14 step process for fabricating a custom obturator to restore functions and improve the patient's quality of life.
Diagnosis and management of anterior crossbite .
The patients usually see the cross-bite as a severe aesthetical problem. The orthodontists see the problem as a severe functional and anatomical disturbance.
The problem “cross-bite” is a result of an anatomical or functional disturbance in the occlusion.
“The best time to treat a crossbite is the first time it is seen”
Or else it may grow into Skeletal Malocclusion
Many treatment modalities ranging from simple to complex means are available to correct anterior crossbite ; some use removable appliances and others use fixed appliances
The document discusses midline diastemas, which are spaces between the two central incisors. It defines midline diastemas and discusses their various etiologies such as normal development, tooth material deficiencies, physical impediments like habits or retained primary teeth, and iatrogenic causes from procedures like rapid maxillary expansion. The diagnosis involves a clinical exam and radiographs to identify the cause. Treatment involves removing the cause, using appliances to close the space, and retainers to maintain results. Midline diastemas can be aesthetically improved through various orthodontic or restorative techniques.
This document provides an overview of mixed dentition and orthodontic appliances used during this period. Mixed dentition refers to the stage when primary teeth are being replaced by permanent teeth, between ages 6-13 years. Common orthodontic problems in mixed dentition include increased overjet and open bite. Functional appliances discussed include oral screens, lip bumpers, activators, and Frankel's regulator. Other appliances mentioned are space maintainers, tongue blades for crossbite correction, and space regainers. The document outlines the principles, advantages, limitations and indications for different appliances used in intercepting and correcting malocclusions during mixed dentition.

4 prevention of occlussal abnormalitiesLama K Banna
This document discusses preventive orthodontics and the role of the general dentist. It emphasizes the importance of the dentist understanding normal facial development, recognizing early deviations, and identifying factors that can cause malocclusion. The dentist should monitor patients from age 5 onwards and watch for issues like retained primary teeth, habits like thumb sucking, and ectopic eruption of molars that may require early intervention. The goal is to either address problems preemptively or determine when orthodontic treatment may be needed and refer patients accordingly.
Preprosthetic mouth preparation involves procedures done prior to prosthetic treatment to facilitate treatment. This includes relieving pain and infection through extractions or fillings, correcting occlusal planes through orthodontics or splinting, and conditioning abused tissues through periodontal therapy or alveoplasty. The goal is to remove any hindrances to prosthetic treatment by managing dental and periodontal issues, extracting problematic teeth, and shaping tissues.
Orthodontics involves the diagnosis, prevention and treatment of malocclusion and dental irregularities. Corrective orthodontic treatment often utilizes fixed appliances, such as brackets and archwires, along with various separators and ligatures to gradually move teeth into proper alignment. Diagnostic records such as photos, radiographs and models are used to evaluate a patient's condition and plan an appropriate orthodontic treatment approach.
Posterior crossbite refers to an abnormal transverse relationship between the upper and lower posterior teeth, where the mandibular buccal cusp occludes buccal to the maxillary buccal cusp. Posterior crossbites can be classified based on etiology, number of teeth involved, unilateral/bilateral involvement, and extent. Management depends on whether the crossbite is dental, skeletal, or functional in nature, and involves appliances like Coffin springs, W-arches, quad helix, and rapid maxillary expansion to correct the underlying discrepancy. Early treatment of posterior crossbites is important to allow for proper arch development and prevent future malocclusions.

This document discusses crowding in mixed dentition and various treatment options. It begins by explaining that crowding is a primary reason parents bring children to the dentist. For mild crowding under 4mm, a lower lingual arch or palatal holding arch can be used to prevent need for future orthodontics. Patients predicted to have over 5mm of crowding should be referred to an orthodontist. Space loss can be addressed through observation, disking primary teeth, extractions, or corrective orthodontics. The document discusses various space maintainers and appliances that can be used for different clinical scenarios to address crowding and space management in mixed dentition.

This document discusses single complete dentures opposing natural teeth. It defines a single complete denture as a prosthesis that replaces all lost teeth in one arch. Challenges include managing high occlusal forces from natural teeth and accommodating the occlusal form of remaining teeth. Diagnosis requires evaluating support, interarch relationships, and preserving remaining structures. Various combinations are described, like a maxillary complete denture opposing natural mandibular teeth. Methods to achieve balanced occlusion include functional jaw movements to record occlusal schemes or articulator-based equilibration.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. POSTERIOR CROSSBITE IN
PRIMARY AND MIXED DENTITION:
ETIOLOGY AND MANAGEMENT
DEPARTMENT OF PEDIATRIC DENTISTRY
www.indiandentalacademy.com
3. DEFINITION OF CROSSBITE
According to Graber:
A condition where one or more teeth may be malposed
abnormally-buccally or labially or lingually with refernce
to opposing tooth or teeth.
Other definition:
-A deviation of the normal faciolingual relationship of teeth of
one
arch with those of opposing arch when the two dental arches are
brought into centric occlusion
OR
-Abnormal occlusion in the transverse plane
OR
-Reverse overjet of one or more teeth
www.indiandentalacademy.com
4. INTRODUCTION
Under normal circumstances- maxillary arch overlaps
mandibular arch both labially and buccally.
But when mandibular teeth (single tooth or a segment of
teeth) overlap maxillary teeth labially or buccally depending
upon their location in the arch a crossbite is said to exist
www.indiandentalacademy.com
5. CLASSIFICATION OF CROSSBITES
(1) According to the location in the arch
Anterior Posterior
(2) According to the nature of crossbite
Skeletal Dental Functional
crossbite crossbite crossbitewww.indiandentalacademy.com
6. POSTERIOR CROSSBITE
-This refers to an abnormal transverse relationship between upper
and lower posterior teeth.
- In normal circumstances –mandibular buccal cusps occlude in the
central fossae of maxillary posterior
teeth.
- In posterior crossbite case – mandibular buccal cusp occlude
buccal to maxillary buccal cusp.
PREVELANCE:
In a study (By Kutin and Hawes) involving 515 children, 3-9 years
of age :- the prevelance of posterior crossbite in primary and
and mixed dentition is 1:13 or 7.7%
www.indiandentalacademy.com
7. CLASSIFICATION OF POSTERIOR CROSSBITES
(1) According to the number of teeth involved

posteriors
www.indiandentalacademy.com
9. ETIOLOGY
Based on etiologic factors responsible for crossbite:
CROSSBITE
Dental Skeletal Functional
www.indiandentalacademy.com
10. Dental crossbites
- Generally, single tooth/segmental crossbite.
- No threat to general health of the patient
- Problems arising are – periodontal/ esthetic in nature.
- Usually result from faulty eruption pattern with no irregularity
in the basal bone.
- Once the teeth erupt – the occlusion locks them into position and
drives them even further into a crossbite relationship.
www.indiandentalacademy.com
11. Etiology of dental crossbite are :-
1) Anomalies in tooth number supernumerary teeth
missing teeth
2) Anomalies in tooth size microdontia
macrodontia
3) Anomalies in tooth shape
4) Premature loss of deciduous/ permanent teeth
5) Prolonged retention of deciduous teeth
6) Delayed eruption of permanent teeth
7) Abnormal eruption path
8) Ankylosis
www.indiandentalacademy.com
12. SKELETAL CROSSBITE
- It results from discrepancy in structure of maxilla and mandible
or – malposition of the jaw.
- A basic discrepancy in the width of arches is noted.
- A narrow maxillary arch or a wide mandibular arch often
assosciated with a buccal crossbite.
- They cause appreciable damage to a person’s health and
personality.
www.indiandentalacademy.com
13. Etiology of skeletal crossbites
1) Retarded development of maxilla.
2) Narrow upper arch.
3)Forwardly placed mandible.
4) Unilateral hypo/hyperplastic growth of any jaw.
5) Hereditary (Class III skeletal malocclussion).
6) Congenital ( Cleft lip and palate).
7) Trauma at birth (forcep injury leading to ankylosis of TMJ.)
8) Trauma during growth (ankylosis of TMJ and retardation of
growth in traumatized bone).
9) Trauma after completion of growth (malunion of fracture
segments).
10) Habits such as prolonged thumb sucking and mouth breathing.
Because they cause lowered tongue position ,thus tongue no longer
balances the forces exerted by the buccal group of musculature,
which leads to narrowing of upper arch leading to posterior crossbite.
11) According to RUTRICK – the use of traditional slender type of pacifiers can
cause crossbite.
www.indiandentalacademy.com
14. Functional crossbite
- An acquired muscular reflex pattern during closure of mandible
is involved in functional crossbite.
- Presence of occlusal interferences can result in deviation of
mandible during jaw closure.
- Other causes are : early loss of decidous teeth
decayed teeth
ectopically erupted teeth.
- Thus a functional crossbite results from the mandibular shifting
into an abnormal but often a more comfortable position.
www.indiandentalacademy.com
15. MANAGEMENT
In normally growing mandible, posterior crossbites should be
treated as early as possible to allow the normal growth and
development of the dental arches and the TMJ.
Posterior crossbite management
IN PRIMARY IN MIXED
DENTITION DENTITION
www.indiandentalacademy.com
16. In primary dentition
- Posterior crossbite in primary dentition is usually as a result of
constriction of the maxillary arch which often results from an
active digit or pacifier habit.
- Determine whether there is an associated mandibular shift.
Mandibular shift
present not present
treatment is implemented treatment is delayed until the
to correct the crossbite permanent first molars erupt
If the first permanent If the first permanent
molar erupts into crossbite molar erupts normally
Treatment is initiated Treatment is not indicated until
(if no other malocclusion exists) the permanent premolars erupt
www.indiandentalacademy.com
17. In mixed dentition
- Posterior crossbite correction in mixed dentition can be difficult
and confusing.
- The clinician should rely on a well documented database to
determine whether a skeletal/dental correction is necessary.
- And in areas where mandibular shift is present it should be
managed as soon as possible to prevent soft tissue and
dental compensation.
Posterior dental crossbite
Generalized Localized
Unilateral Bilateral
www.indiandentalacademy.com
18. The various treatment modalities for
posterior crossbite are :-
1) Occlusal equilibrium.
2) Coffin spring.
3) Cross elastics.
4) Soldered W –arch (Porter appliance).
5) Quad Helix.
6) Removable appliance.
7) Rapid maxillary expansion (RME).
8) Ni-Ti expanders.
9) Oral screening.
10) Fixed orthodontic appliances.www.indiandentalacademy.com
19. OCCLUSAL EQUILIBRIUM
- A dental, bilateral, lingual crossbite in primary and mixed
dentition may be simply corrected by removing the occlusal
interferences usually in the cuspid area.
- This may be sometimes needed to be accompanied by some
appliance.
www.indiandentalacademy.com
20. COFFIN SPRING
- It was designed by Walter Coffin.
- It is a removable,omega shaped wire appliance
- It produces slow and bilaterally symmetrical expansion.
- It consists of omega shaped wire of 1.25 mm diameter
placed in mid palatal region.
- Free ends of omega are embedded in an acrylic plate that covers
the slopes of the palate.
- It brings about dento alveolar expansion.
- However, it is capable of skeletal changes when used in mixed
dentition with a good retention.
www.indiandentalacademy.com
21. CROSS ELASTICS
- It is used to treat localized crossbites.
- Select, fit and burnish appropriate band to maxillary and
mandibular teeth.
- Solder hooks or button to the bands- - -
on palatal surface of the maxillary teeth and
on buccal surface of the mandibular teeth.
- After these bands are welded and cemented rubber elastics is
attached on the hooks as shown in fig.
- The rubber elastics used are – heavy rubber elastics,
0.25 i.e. 3/16 inch and
6 ounce elastic
www.indiandentalacademy.com
22. - The elastic should be worn full time except while eating.
- Change it atleast once per day.
- The elastics are worn until the crossbite is slightly over corrected.
- Crossbites are ususally corrected within 3-4 months (with
continuous wearing of elastics).
- Major change will be reflected in position of the maxillary molar
because of the cancellous nature of the maxillary alveolar bone
compared with denser bone around mandibular molar.
- Advantage - Usually no need of retentive appliance
- Disadvantages – Needs patient’s co operation and
is technically more difficult.
www.indiandentalacademy.com
23. SOLDERED W – ARCH
(PORTER APPLIANCE)
- It is an efficient appliance for the correction of posterior
crossbite as well as a reminder appliance in some posterior
crossbites assosciated with thumb sucking.
- Preformed stainless steel bands are adapted to the most distal tooth involved.
- W-arch is constructed of 0.036-0.040 inch steel wire- contoured to the arch.
- Wire is made free of tissue by 1-2 mm.
- Anterior extension of the wire should touch only the teeth that must be moved
buccally.
- W-arch is expanded about 4mm wide than its passive width or so that one arm of
“W” is resting over central grooves of teeth when the other arm is in proper position.
www.indiandentalacademy.com
24. - The appliance is cemented during active treatment.
- Activate the appliance by slightly opening the palatal loop with a
corresponding adjustment in the molar loop area.
- The appliance activation:- intra orally
or extra orally.
- Appliance expands the arch approx 1mm/side/month.
- Activated every 3-4 weeks until crossbite is slightly over corrected.
- Retainer used for additional 3 months.
www.indiandentalacademy.com
25. Modification : UNEQUAL W-ARCH
- Used in case of true unilateral crossbites.
- It has long and short arms.
- Short arm- touches only the teeth to be moved.
- Long arm – touches as many contralateral teeth as possible.
- The idea behind the unequal W-arch is to pit the movement of a
large number of teeth against movement of small number of teeth.
- The side with smaller number of teeth – more movement
side with larger number of teeth - less movement.
www.indiandentalacademy.com
26. QUAD HELIX
- Introduced by Currier and Austerman, 1993.
- The quad helix is a spring that consists of 4 helices-
2 helices in the anterior palate and
2 helices near solder joint in the posterior palate.
- It is capable of dento alveolar as well as skeletal expansion.
PROCEDURE :
Fit bands to either primary second molars or the permanent first molars.
Take a complete arch impression.
Remove the bands from teeth and seat them in proper position
Seal in place and make a working cast of stone
Use a 0.032 stainless steel wire,
this stainless steel wire contacts all posterior teeth,
anterior aspect of wire is just distal to primary canines,
the contact is close to, but not touching the soft tissue at cervical margin,
the loops or helixes and palatal portion should be 2-3 mm distal to banded teeth
Secure the wire to working cast,solder the wire to molar bands.
www.indiandentalacademy.com
27. - Activate the appliance prior to cementation.
- Activation is done intra orally - using triple beak plier
extra orally – using hand.
- Activation is done in 2 steps :
Step 1 – Activate the posterior helical loops,
moving the free wires buccally.
Step 2 – Activate the anterior helical loops
moving the molar bands buccally.
www.indiandentalacademy.com
28. - When the wire has been activated the lingual surface of molar
bands will be above the central fossa of the molars.
- The anterior portion of wires will be above the canine cusp tip.
- The appliance produces slow expansion
- Crossbite corrected in 4-6 months.
- Retain the same appliance for further 3 months.
- The quad helix can be used simultaneously with
full bonded appliance therapy.
Modification – UNEQUAL QUAD HELIX
Same as unequal W- arch
Used to correct unilateral crossbites
www.indiandentalacademy.com
29. REMOVABLE APPLIANCES
- Lateral maxillary expansion is achieved with a parallel expansion screw
housed in upper acrylic plate.
- The appliance should have excellent tissue contact and anchorage with clasps on teeth.
- Provide acrylic relief – palatal to anterior teeth.
- The labial bow should be passive; when expansion occurs-bow becomes activated.
- A full turn is achieved with 4 turns of a key.
- The conventional expansion schedule– ¼ turn every 3-4 days.
- Correction is dental only.
- It causes bilateral expansion.
- Relapse potential is high.
www.indiandentalacademy.com
30. RAPID MAXILLARY EXPANSION
- Rapid maxillary expansion is indicated for severe cases of bilateral
crossbites where correction requires skeletal expansion.
- It involves the splitting of the mid palatal suture
orthopaedic increase in maxillary width.
- It can easily occur in a growing child (< 9 years).
- The appliance uses a mid–palatal screw (Hyrax) – soldered to bands
on the first permanent molars and primary molars.
RME screw
Banded RME Cemented RME.
www.indiandentalacademy.com
31. - The screw is activated a quarter turn twice each day.
- Patient is monitored once a week.
- It brings about 0.2-0.5 mm/day expansion.
- The appliance produces a rapid expansion over 3-4 weeks.
- Crossbite should be over corrected and then retained for atleast
3 months with the same applaince.
www.indiandentalacademy.com
32. NICKEL TITANIUM EXPANDERS
- They bring about slow expansion (dental changes).
- They require less adjustments than conventional stainless steel
quad helix appliances.
- Molar bands are cemented to maxillary first permanent molars
welding is done.
Ni–Ti wire shapes are attached to lingual sheath
of welded molar band.
- Various sizes are available and need to be selected depending on :
- the amount of expansion desired
- pre treatment width of the palate
www.indiandentalacademy.com
33. - Cooling the expander it gets constricted
it gets inserted into lingual tubes on the
maxillary molars.
As it warms to body temperature it becomes springy
exerts continuous force on teeth
arch expansion
www.indiandentalacademy.com
34. ORAL SCREEN/VESTIBULAR SCREEN
- Introduced by Newell in 1912.
- It is a myofunctional appliance – that takes form of a curved acrylic
shield placed in labial vestibule.
PRINCIPLE :
It works on the principle of
force application + force limitation.
i.e. to apply the forces of circumoral musculature to certain teeth
OR
to relieve those forces from teeth
therefore allowing them to move due to forces exerted by tongue
It works on principle of “PASSIVE EXPANSION”
www.indiandentalacademy.com
35. INDICATIONS :
To intercept habits – mouth breathing
thumb sucking
tongue thrusting
lip/cheek biting
To treat mild disto-occlusions.
To perform muscle exercise to help correction of hypotonic
lip and cheek muscles.
CONTRAINDICATIONS :
In children with nasal obstruction or
respiratory distress
www.indiandentalacademy.com
36. PROCEDURE :
Take upper and lower impressions and pour working models
Casts are occluded in normal intercuspation and sealed
Extend vestibular screen into sulcus–
(where mucosal tissue reflects)
Posteriorly extend the appliance upto distal margin of
the last erupted molar.
Note : The material used is SELF CURE/HEAT CURE acrylic resin.
The patient is made to wear the appliance at night and 2-3 hours
during the day time and maintain lip seal.
www.indiandentalacademy.com
37. MODIFICATIONS :
Hotz modification – made up of additional metal ring.
Patient with tongue thrust – additional screen placement on lingual
aspect
In Mouth breathers – vestibular screen with a number of holes
which are gradually decreased
www.indiandentalacademy.com
38. FIXED ORTHODONTIC APPLAINCES
- Fixed orthodontic appliances can be used for correction
of posterior crossbites.
- The arches can be kept slightly expanded depending upon the
movement required.
- Cross elastics can be used to bring about correction of
individual tooth crossbite in posterior segment.
- Fixed orthodontic appliance are ideal for accurate placement of
teeth in a dental arch as they provide a three dimensional control
over the tooth.
www.indiandentalacademy.com
39. CONCLUSION
The early and correct diagnosis of posterior crossbite is essential
to prevent the forthcoming occlusal discrepancies in the
permanent
dentition.
Adequate curative measures and treatment modalities should be
advocated to correct the posterior crossbite
