This document discusses adult orthodontics, including:
- The history of adult orthodontics dating back to 1880.
- Reasons for the increased interest in adult orthodontics, such as improved appliance techniques and patient awareness.
- Differences between treating adult vs. adolescent patients, including that adults have no growth potential and require more collaboration with other specialists.
- Types of adult orthodontic patients and treatments, including adjunctive treatment to facilitate restorations by positioning teeth.
- Goals and procedures for adjunctive treatment focus on improving periodontal health and crown-root ratios by uprighting teeth.

3. Adult is defined as one who is fully
grown,most males 18 and above and
most females of 16 and above can be
considered to be adult,although residual
growth is left. It is however quite
impractical to determine the exact time
when adulthood begins.
www.indiandentalacademy.com
4. HISTORY:
- Kingsley, in 1880,indicated an early
awareness regarding orthodontic
potential in adult patient.
- He stated, “It may be regarded as
settled fact that there are hardly any
limits to the age when movement of teeth
might not succeed.”
www.indiandentalacademy.com
5. Acc. To MacDowell(1901),
after the age of 16 years, a complete and
permanent change in transition of the
occlusion is almost impossible owing to
the development of,
- adult glenoid fossa,
- density of the bones ,
- muscles of mastication.
www.indiandentalacademy.com
6. In 1921 Calvin Case demonstrated the
value of orthodontic therapy for the
patient with pyorrhea in the lower
anterior area.
www.indiandentalacademy.com
7. Adult orthodontics:-
Acc. To Ackerman, “adult orthodontics
is concerned with striking a balance
between achieving optimal proximal and
occlusal contact of the teeth,acceptable
dentofacial aesthetics, normal function
and reasonable stability.”
www.indiandentalacademy.com
8. Reasons for the increased interest by
orthodontists in the adult as a patient and
vice versa.
1) Improved appliance placement
techniques.
www.indiandentalacademy.com
9. 2) Better management of joint
dysfunction.
3) More effective management of
skeletal jaw dysplasias with advanced
orthognathic surgical techniques.
www.indiandentalacademy.com
10. 4) Increased desire of patients and
restorative dentists for treatment of
dental mutilation problems using tooth
movement and fixed restorations rather
than removable prostheses.
5) Reduced vulnerability to periodontal
breakdown as a result of improved tooth
relationships and occlusal functions.
www.indiandentalacademy.com
11. 6) Role of media, visual as well as print
articles in magazines ,news paper as
well as community programs have
increased patient awareness.
7) A broader understanding of the
biology of the tooth movement,esp. with
regard to age changes.
8) Ingenious approaches to anchorage
management such as implants.
www.indiandentalacademy.com
12. INDICATIONS: (BY RAVINS)
1) Improvement of tooth-periodontal
tissue relationship.
2) Establishing an improved plane of
occlusion to distribute the forces of
occlusion better.
3) Balancing the existing space for better
prosthetic replacement.
4) Improve occlusion and coordination
between the muscle and TMJ.
5) improve patient esthetic.www.indiandentalacademy.com
13. CONTRAINDICATIONS: (BY
BARRER)
1) Severe skeletal discrepancies.
2) Advanced local or systemic disease.
3) Excessive alveolar bone loss.
4) Poor stability prognosis.
5) Lack of patient motivation.
www.indiandentalacademy.com
14. But mark and cosrn disagree with this
list except for systemic disease and lack
of patient motivation.
www.indiandentalacademy.com
15. DIFFERENCE B/W ADOLESCENT
AND ADULT ORTHODONTIC
PATIENT.
Acc to levitt, “ in adult patient there is no
growth and only tooth movement”.
Acc to Barrer “ adult, unlike the child is
a relentless patient, who will not cover
our deficiencies in skills or our errors in
the use of mechanical procedures by
helpful settling in post-treatment.”www.indiandentalacademy.com
16. Acc to Ackerman. “ In a child ,one
occasionally calls on another specialist.
On the other hand it is rare adult whom
one treats orthodontically without
finding it necessary to collaborate with
another specialist.”
www.indiandentalacademy.com
17. FOUR MAJOR CATEGORIES IN
WHICH ADULT PATIENT
SIGNIFICANTLY DIFFER FROM
THEIR ADOLESCENT
COUNTERPART:
1) The diagnostic process.
2) Treatment plan selection.
3) Acceptance of recommended therapy.
4) Achievement of treatment objectives.
www.indiandentalacademy.com
18. 1) THE DIAGNOSTIC PROCESS.
Problem oriented dental record aides
in making the appropriate
diagnosis, for it requires that the
patient’s problems be listed and a
plan be developed to manage each
problem.
www.indiandentalacademy.com
19. DIAGNOSTIC STEPS:-
1) Collect data accurately.
2) Analyze data base.
3) Develop problem list.
4)Prepare tentative treatment plan.
5) Interact with those who are involved;
discus plans and options; clarify
sequence, acquire patient acceptance.
6) Create final treatment plan.www.indiandentalacademy.com
20. Before starting the treatment, the
orthodontist needs to be prepared to do
the following:-
1) Diagnose different stages of pdl
disease and their associated risk factors.
2) Diagnose TMJ dysfunction before,
during or after tooth movement.
www.indiandentalacademy.com
21. 3) Determine which cases require
surgical management and which one
require incisor reangulation to
camouflage the skeletal base
discrepancy.
4)Work cooperatively with team of other
specialists to give the patient the best
outcome.
www.indiandentalacademy.com
23. ADDITIONAL ORTHODONTIC
TREATMENT OBJECTIVES:-
1) Parallelism of abutment teeth:-
- Restoration will have better
prognosis.
- Allows for a better pdl response.
- Allows for better retention.
www.indiandentalacademy.com
24. 2) MOST FAVORABLE
DISTRIBTION OF TEETH:-
- Teeth should be positioned in such a
way that occlusion of natural teeth can
be established bilaterally between the
arches.
www.indiandentalacademy.com
25. 3) REDISTRIBUTION OF OCCLUSAL
AND INCISAL FORCES:-
- helpful in case of significant bone
loss.
4) ADEQUATE EMBRESURE SPACE
AND PROPRE ROOT POSITION:-
- Allows for better pdl health.
www.indiandentalacademy.com
26. 5) ACCEPTABLE OCCLUSAL PLANE
AND POTENTIAL FOR INCISAL
GUIDENCE AT SATISFACTORY
VERTICAL DIMENSION.
www.indiandentalacademy.com
27. 6) ADEQUATE OCCLUSAL
LANDMARK RELATIONSHIP.
7) BETTER LIP COMPETECY AND
SUPPORT:-
- Inadequate support may create change
in anteroposterior and vertical position of
upper lip and increse wrinkling.
www.indiandentalacademy.com
28. 8) IMPROVED CROWN/ROOT
RATIO:-
In case of individual teeth bone loss
we can improve the crown to root ratio
by decreasing length of clinical crowns
tooth is erupted orthodontically.
www.indiandentalacademy.com
29. 9) IMPROVEMENT OF
MUCOGINGIVAL AND OSSEOUS
DEFECTS:-
- Proper positioning of teeth in arch will
improve gingival topography.
10) BETTER SELF MAINTEINANCE
OF PDL HEALTH:-
- For better periodontal health tooth
should be positioned properly over their
basal bone support.
www.indiandentalacademy.com
30. 11) ESTHETICS AND FNCTIONAL
IMPROVEMENT.

OFTEN IN THEIR 20’S)
2) OLDER PATIENT IN THEIR 40’S
AND 50’S.
www.indiandentalacademy.com
48. Reasons for not receiving orthodontic

www.indiandentalacademy.com
51. Older patient mainly need treatment
for:-
1) Malposed teeth contributing to pdl
disease.
2) Increased difficulties in mastication.
3) Anterior space enlarging or
developing.
4) For better tooth positioning prior to
prosthetic preparation.
5) Tooth interference that may causes
TMJ problems.www.indiandentalacademy.com
52. ACCORDING TO PROFFIT ADULT
ORTHODONTIC TREATMENT IS
DIVIDED IN TO 3 PARTS:-
1) ADJUNCTIVE TREATMENT.
2) COMPREHENSIVE TREATMENT
FOR ADULTS.
3) SURGICAL TREATMENT.
www.indiandentalacademy.com
53. DIFFERENCE BETWEEN
ADJUNCTIVE TREATMENT AND
COMPREHENSIVE TREAMTMENT
IS INDISTINCT,AS ANY TREAMENT
WHICH REQUIRE MORE THAN 6
MONTHS IS CALLED AS
COMPREHENSIVE TREATMENT.
www.indiandentalacademy.com
54. 1) ADJUNCTIVE TREATMENT:-
“ Tooth movement carried out to
facilitate other dental procedures
necessary to control disease and
restore function.”
www.indiandentalacademy.com
55. GOALS :-
1) Facilitates restorative treatment by
positioning the teeth.
2) Improve periodontal health by
removing plaque harboring areas .
3) Establishing favourable crown to root
ratio and position of the teeth.
www.indiandentalacademy.com
57. -Adult patients demand for removable
appliance but they are not useful in
adjunctive treatment.
- But in case of multiple missing teeth
removable appliance is useful.
www.indiandentalacademy.com
59. - In case of reduce periodontal support
and bone loss , lighter forces and
relatively larger movements are needed.
www.indiandentalacademy.com
60. TIMING AND SEQUENCE OF
TREATMENT:-
- Before any type of tooth movement any
caries or pulpal pathology should be
eliminated.
- Larger restoration require detail
occlusal anatomy should be carried out
after orthodontic treatment is over.
www.indiandentalacademy.com
61. - Periodontal disease should be
controlled before any tooth movement.
- Scaling, curettage and gingival graft
should be carried out before treatment.
- Surgical pocket elimination and
osseous surgery should be carried out
after orthodontic treatment.
www.indiandentalacademy.com
62. PROCEDURES CARRIED OUT IN
ADJUNCTIVE TREATMENT : -
1) UPRIGHTING POSTERIOR TEETH.
2) FORCED ERUPTION.
3) ALIGNMENT OF ANTERIOR
TEETH.
4) CROSSBITE CORRECTION.
www.indiandentalacademy.com
64. 1) If third molar is present , whether
both second and third molar should
be uprighted.
2) Whether to upright tipped teeth
by distal crown tipping or by mesial
root movement.
www.indiandentalacademy.com
66. 3) Whether we need slight extrusion or
maintain occlusal height during
uprighting.
4) Whether premolar should be
repositioned or not.
www.indiandentalacademy.com
67. APPLIANCE FOR MOLAR
UPRIGHTING:-
- Partial fixed appliance.
- Anchorage.
- Placement of brackets on canine and
premolars.
www.indiandentalacademy.com
71. • Severely tipped teeth:-
- Use of modified T-
loop.
www.indiandentalacademy.com
72. • Final position of
molars and premolars.
• Use of open coil
spring - steel
- A Ni-Ti
• Occlusion should be
checked carefully.
www.indiandentalacademy.com
73. RETENTION
• For shorter period
• For a longer period.
- Intracoronal wire
splint
www.indiandentalacademy.com
76. TREATMENT PLANING:-
- Periapical radiograph.
- Single tapering and flared and
divergent root morphology.
- Endodontic therapy.
www.indiandentalacademy.com
77. How much tooth should be extruded can
be determine by 3 factors:-
1) Location of the defect.(fracture line)
2) Space to place margin of the
restoration.(1 mm)
3) An allowance for the biological width
of the gingival attachment.(2 mm)www.indiandentalacademy.com
83. ALIGNMENT OF ANTERIOR TEETH
Indications:-
1) To improve access and permit
placement of well contoured restorations.
2) To permit placement of crowns and
pontics .
www.indiandentalacademy.com
84. 3) To reposition closely approximated
roots and to improve the amount of
interradicular bone.
4) To position teeth so that implants can
be placed to support restorations.
www.indiandentalacademy.com
85. * Alignment of crowed, rotated and
displaced incisors.
* Separation of approximated teeth.
www.indiandentalacademy.com
86. • Position teeth for single tooth implant:-
- Minimum 6mm of space is require.
- Apices of adjacent teeth.
www.indiandentalacademy.com
87. Anterior diastema closure and
space redistribution:-
Causes:-
- Loss of posterior teeth.
- Small teeth.
.- Loss of bone support.
www.indiandentalacademy.com
89. CROSSBITE CORRECTION:-
- It can cause functional problem and
occlusal trauma.
- Single tooth crossbite.
- Group of teeth in crossbite.(part of
skeletal problem).
www.indiandentalacademy.com
90. - Correction with removable
appliances.(anterior segment)
- Correction with the “through the bite”
elastics.(posterior segment).
www.indiandentalacademy.com
92. SUMMARY:-
There is wide variety of
etiology that can cause an adult
malocclusion. Also each patient’s need
for treatment are different so treatment
should be carried out taking his/her
needs in consideration.
Adjunctive treatment helps by
facilitating other dental procedures to
control disease and restore function.
www.indiandentalacademy.com
93. PERIODONTAL ASPECT OF ADULT
TREATMENT:-
1) Minimal periodontal involvement.
2) Moderate periodontal involvement.
3) Severe periodontal involvement.
www.indiandentalacademy.com
94. 1) MINIMAL PERIODONTAL
INVOVEMENT: -
CHILDREN AND ADOLESCENT
ARE LESS SUSEPTIBLE TO
PERIODONTAL DISEASE THAN
ADULTS.
www.indiandentalacademy.com
95. 2) MODERATE PERIODONTAL
INVOVEMENT: -
All periodontal disease should be
controlled before tooth movement.
Fully bonded orthodontic appliance is
preferred in periodontally involve adult
patient.
www.indiandentalacademy.com
96. Steel ligatures or self legating brackets
are preferred.
Periodontal maintenance therapy at 2-4
month interval.
www.indiandentalacademy.com
97. 3) SEVERE PERIODONTAL
INVOVEMENT: -
Periodontal maintenance should be
scheduled at more frequent intervals.
Orthodontic goals and mechnics should
be modified to keep force value
minimum.
www.indiandentalacademy.com
98. SPACE CLOSURE VS. PROSTHETIC
REPLACEMENT: -
Old extraction site: -
Space closure is difficult in adult.
The involvement of cortical bone tend to
produce reciprocal space closure.
Implant in the ramus can be use to
provide necessary anchorage.www.indiandentalacademy.com
99. TOOTH LOST DUE TO
PERIODONTAL DISEASE: -
Unwise to move a teeth in area where
bone is destroyed because of periodontal
disease.
www.indiandentalacademy.com
100. SURGICAL TREATMENT: -
- orthognathic basically involves planned
fracturing of the facial skeletal parts and
reposition them as desired.
- Moderate to severe skeletal
discrepancy.
- Patient education.
www.indiandentalacademy.com
101. SURGICAL PROCEDURES: -
1) Correction of anteroposterior
relationship: -
both maxilla and mandible can be moved
forward or backward for correction of
jaw discrepancy.
www.indiandentalacademy.com
102. A) MAXILLARY SURGERY: -
The LeFort 1 downfracture
procedure is used to reposition the
maxilla.
www.indiandentalacademy.com
104. B) MANDIBULAR
ADVANCEMENT:-
- Bilateral saggital split
osteotomy(BSSO) of the mandibular
ramus.
- stretching and retraction of the inferior
alveolar nerve.
www.indiandentalacademy.com
106. C) MANDIBULAR SETBACK: -
- BSSO.
- The transoral vertical oblique ramus
osteotomy(TOVRO).
www.indiandentalacademy.com
107. 2) CORRECTION IN VERTICAL
PLANE: -
a) Maxillary surgery: -
- LeFort 1 downfracture of the maxilla,
with superior reposition of the maxilla.
- In downward movement of the maxilla
rigid fixation are used.(synthetic
hydroxyapatite)
www.indiandentalacademy.com
109. b) Mandibular surgery: -
mandibular ramus surgery in open bite
cases avoided.
Short face(skeletal deep bite) best treated
by saggital split mandibular ramus
surgery.
www.indiandentalacademy.com
110. 3) CORRECTION OF TRANSVERSE
RELATIONSHIP: -
easy to move maxilla in transverse
direction then mandible.
www.indiandentalacademy.com
111. A) MAXILLARY EXPANTION: -
Constriction or expantion done
during course of Lefort 1
downfracture procedure.
www.indiandentalacademy.com
113. RETENTION: -
- More difficult in adult then in
adolescent patient ,
- slower tissue turn over rate.
- Normal functional adaptation occurs
more when growth has been completed.
- Reduce height of periodontium.
www.indiandentalacademy.com
114. -Hawley retainer.
- Hawley retained with tongue cribs.
- fixed bonded retainer(max. and mand.
Anterior segments)
www.indiandentalacademy.com
118. TMD as motivating factor for adult
patient.
Orthodontic treatment helps patient
with TMD problems.
www.indiandentalacademy.com
119. TMD symptoms can be divided in 2
groups: -
- Internal joint pathology.(Arthritis)
- Symptoms of muscle origin caused
by spasm and fatigue of the muscle.
www.indiandentalacademy.com
123. EVENTS: -
1) Local events: -
- History of bruxism.
- Trauma
- Poorly aligned teeth.
- Placement of improperly occluding
crown.
- Loss of posterior teeth.www.indiandentalacademy.com
124. Systemic events: -
- Emotional stress.
- Acc. To Han Selye “ Stress is a
non specific response of the body to
any demand made upon it.”
Physiologic tolerance.
www.indiandentalacademy.com
125. Clinical presentation: -
- Pain at preauricular area or temple
area or at ear when chewing or
opening the mouth.
- Pain may radiate to head, face or
eye.
www.indiandentalacademy.com
126. Behavioral changes like,
- Avoiding wide opening of the
mouth.
- Patient prefers softer food.
www.indiandentalacademy.com
144. TREATMENT OF TMD
• Control of myofacial pain.
• Treatment of TMJ.
www.indiandentalacademy.com
145. Three approaches to control
myofascial pain: -
1) Reducing the amount of stress.
2) Reducing the patient’s reaction to
the stress.
3) Improving the occlusal
relationship.www.indiandentalacademy.com
151. OCCLUSAL APPLIANCE
THERAPY
• It is a removable device, usually
made up of hard acrylic that fits
over the occlusal and incisal
surfaces of the teeth in one arch
, creating precise occlusal contact
with the teeth of the opposing arch.
www.indiandentalacademy.com
159. FINAL CRITERIA FOR
STABILIZATION APPLIANCE
• Appliance must accurately fit the maxillary
teeth.
• In centric relation all posterior mandibular
buccal cusp must contact on flat surface
with even force.
• In any lateral movement only mandibular
canines should exhibit contact on the
appliance.
• It should polished.www.indiandentalacademy.com
160. ANTERIOR REPOSITIONING
APPLIANCE
• It is an interocclusal devise that
encourages the mandible to assume a
position more anterior then the
intercuspal position.
• Mainly used to treat disc derangement
disorders.
www.indiandentalacademy.com
161. Locating the correct anterior position
• Anterior stop is constructed.
• Joint symptoms are evaluated.
www.indiandentalacademy.com
164. The moment of truth for TMD
symptoms comes after orthodontic
treatment is completed, when
clenching and grinding that
originally caused the problem tend to
recur.
www.indiandentalacademy.com
166. 1) INRINSIC: -
- Adults are no longer growing.
- PDL status.
www.indiandentalacademy.com
167. ACCORDING TO CHASENS,
ORTHODONTIC TREATMENT
SHOULD BE AVOIDED IN
FOLLOWING CLINICAL
SITUATIONS: -
1) Incontrolled inefection and
inflammation.
2) Inadequate retention is present.
www.indiandentalacademy.com
168. 3) Lack of patient motivation and
cooperation.
4) Systemic problems which cannot be
treated or difficult to control.
www.indiandentalacademy.com
169. SUMMARY:-
There is wide variety of
etiology that can cause an adult
malocclusion. Also each patient’s need
for treatment are different so treatment
should be carried out taking his/her
needs in consideration.
Adjunctive treatment helps by
facilitating other dental procedures to
control disease and restore function.
www.indiandentalacademy.com
170. TMD serves as one of the motivating
factors for adult patient to visit
orthodontist. Relief of pain by providing
adequate TMJ therapy motivates patient
to undergo the remaining restorative or
orthodontic treatment.
