This document provides information on using infrazygomatic crest implants (IZC) for orthodontic anchorage. It discusses the history, anatomy, dimensions, indications, placement sites and guidelines for IZC. Case examples demonstrate using a self-drilling IZC screw for asymmetric distalization of the maxillary arch to correct a dental midline. Placement of the IZC screw allowed for full arch distalization without complex appliances. The treatment resulted in a Class I molar and canine relationship bilaterally with an improved dental and soft tissue profile. Complications and failure rates of IZC are also reviewed.

Anterior Open Bite etiology and differential diagnosisMarwan Mouakeh
This document discusses the etiology and classification of anterior open bite. It defines anterior open bite and discusses its prevalence, which can range from 1.5-11% and varies among races. Anterior open bite is classified as dental, dentoalveolar, or skeletal depending on whether it is restricted to the anterior teeth or involves the underlying skeletal structures. The etiology of anterior open bite is multifactorial, involving genetic, anatomic, and environmental factors. Genetic factors include unfavorable growth patterns and increased tongue size. Environmental factors prominently include non-nutritive sucking habits which can cause dental changes, as well as abnormal tongue function and airway obstructions.

The document also discusses individualizing treatment proposals based on factors like soft tissue function.
Modification of twin block functional applianceMaher Fouda
This document discusses the Twin Block appliance, which was originally developed by Clarke. It remains a widely used functional appliance for treating Class II malocclusions. The Twin Block consists of separate upper and lower acrylic appliances connected by occlusal blocks. It works by forcing the mandible into a protrusive position during jaw closure. The document describes the standard Twin Block design and various modifications that have been made, including the addition of expansion screws, torquing springs, and bite jumping screws to allow for gradual advancement. Advantages include comfort, aesthetics, and improved patient compliance compared to fixed appliances. The Twin Block is effective at correcting Class II malocclusions in a rapid manner.
The document discusses different types of headgears used in orthodontic treatment including cervical headgear, high-pull headgear, combination headgear, and headgear attached to the lower jaw. It explains how the position of the outer bow relative to the center of resistance and line of force determines the direction of tooth movement and effects on the occlusal plane. Intrusive, extrusive, clockwise, and counterclockwise moments can be created by adjusting the outer bow position. The timing and indications for different headgear types are also covered.

The document discusses Ronald Roth's modifications to the Andrews Straight Wire Appliance philosophy and treatment approach. Roth started using the Andrews appliance in 1970 and later modified the bracket prescription based on his clinical experience. Some key differences between Andrews and Roth include Roth allowing more tipping of teeth initially and building overcorrection into the brackets to account for relapse. Roth also placed more emphasis on achieving a gnathological occlusion goal versus Andrews' focus on anatomical tooth positions. The document outlines Roth's bracket placement, prescription, and rationale for his modifications to the straight wire appliance.

The document discusses the Opus loop, a new orthodontic closing loop design developed by Raymond Siatkowski. It aims to deliver a consistent moment-to-force ratio (M/F) of 8-9 mm without adding residual moments. Traditional loops require residual moments via bends to achieve desired M/F ratios. The document outlines the theoretical basis for the Opus loop's design using Castigliano's theorem. Finite element analysis confirmed it maintains a consistent high M/F when positioned off-center. Experimental testing of prototypes verified the Opus loop achieves its intended M/F range, representing an improvement over other loops.

This document discusses various orthodontic appliances used for intrusion, including the three-piece intrusion arch, Rickets utility arch, K-SIR appliance, and Connecticut Intrusion Arch. It describes how each appliance works and its advantages. The three-piece intrusion arch uses an intrusive cantilever to simultaneously intrude and retract anterior teeth. The Rickets utility arch engages two molars and four incisors to intrude lower incisors. The K-SIR appliance modifies loop mechanics to simultaneously intrude and retract teeth. The Connecticut Intrusion Arch incorporates characteristics of the utility arch and conventional intrusion arch to achieve absolute intrusion of anterior teeth.
The document summarizes the first stage of Begg's appliance in orthodontic treatment. Stage I objectives include closing spaces, correcting crowding, overcorrecting rotations, overjet, and overbite. Anterior teeth undergo labial/lingual, intrusive, and retractive movements. Posterior teeth are maintained upright or overcorrected distally. Characteristic archwires include plain or looped 0.016" wires. Class II or III elastics are used. Bracket placement and archwire details such as offsets are described.
This document provides a history of the evolution of bonding in orthodontics from the 1960s to present day. It discusses key developments such as the introduction of acid etching by Buonocore in the 1950s, the early use of epoxy and composite resins for bonding by Newman and Miura in the 1960s-1970s, the introduction of visible light curing systems in the 1980s, and the development of self-etching primers in the 2000s. Bonding has evolved from using fillings materials to specialized orthodontic bonding resins and primers, and techniques now allow bonding to both dry and wet enamel surfaces.

The document summarizes the Royal London Space Planning approach for orthodontic treatment planning. The approach involves assessing six factors that impact the space required for treatment: crowding, occlusal curves, arch width, incisor positioning, tooth angulation, and tooth inclination. Scores are recorded for each factor to quantify the overall space needed. The approach aims to ensure a systematic treatment plan, determine if objectives are achievable, anticipate anchorage issues, and improve informed consent.

Midline shift /certified fixed orthodontic courses by Indian dental academy Indian dental academy
This document discusses midline shift, including its causes, diagnosis, and treatment. Midline shift can be caused by dental factors like tooth loss or retention, or skeletal factors like condylar fractures or hemimandibular hypertrophy. Diagnosis involves clinical examination, functional analysis, radiographs, and determining if the shift is dental or skeletal. Treatment depends on the underlying cause, and may involve correcting tooth positioning, expanding the arch, or orthognathic surgery for severe skeletal discrepancies. Maintaining compensatory tooth inclinations is important to properly address underlying skeletal asymmetries.
This document discusses midline discrepancies and facial asymmetry. It begins with definitions and discusses the etiology and diagnosis of asymmetries. Types of midline discrepancies are described. Treatment involves detailed evaluation of the soft tissues, dentofacial skeleton, and dentition using study models, radiographs, and photographs. Occlusion is also evaluated to assess compatibility between centric occlusion and centric relation. Accurate diagnosis of asymmetries requires a systematic approach.

This document discusses non-carious tooth substance loss (NCTSL), which is the loss of dental hard tissues due to causes other than bacteria acting on carbohydrates. It can be caused by factors like erosion from acid, attrition from tooth contact, abrasion from foreign objects, and parafunctional habits. The rates of physiological wear are minimal but can become pathological if the rate exceeds the viability of teeth. Diet, medications, medical conditions and lifestyle factors can influence the rates of wear. NCTSL is a growing problem, especially among children and adolescents, and it can affect aesthetics, function and long term health of teeth if not managed properly. Strategies for managing NCTSL include addressing its causes, using protective

This document discusses various types of fixed functional appliances used to correct Class II malocclusions. It describes removable functional appliances and their disadvantages compared to fixed appliances. Fixed appliances discussed include flexible appliances like Jasper Jumpers and torsion coils, as well as rigid appliances. The document outlines the advantages, indications, contraindications, forces produced, and risks of unwanted tooth movement for different fixed appliance options. It emphasizes the importance of anchorage preparation for successful outcomes.
This document discusses the management of deviated midlines. It notes that differential diagnosis is important to determine the cause of the midline deviation and appropriate treatment. Treatment may involve correcting dental asymmetries through orthodontics or expanding a narrow maxillary arch first if caused by a posterior crossbite. Functional appliances can be used to shift the mandible into the proper position if a skeletal deviation is present. Surgical correction may be needed for true skeletal asymmetries. The goal is to adapt the occlusion and correct dental or facial asymmetries causing the deviated midline.

3. INTRODUCTION
In our life time, we have seen the faces of thousands of people ,
and each face is recognizable to us as distinct individual.
No two faces are quite alike, even those of identical twins.
The coordination of the development of the upper and the lower
jaws are far from perfect. This imperfection can be compensated by
skeletal and dentoalveolar changes camouflaging the actual
deviation.
This mechanism first described by Bjork as
the “dentoalveolar compensatory mechanism” and
www.indiandentalacademy.com
4. “ Process or mechanism by which the
development of dental and alveolar arches are
controlled so as to secure occlusion of the teeth
and adaptation to the basal parts of the jaws.”
www.indiandentalacademy.com
5. What is compensation ???
It is a constant ongoing process striving towards ultimate
homeostasis during growth .
When the growth process is complete a state of compromise
equilibrium has been achieved .
Compensation can be more aptly called as
“ Developmental adjustments for working towards balance ” .
www.indiandentalacademy.com
6. If we have compensatory features , the built in tendencies are
offset , to a greater or lesser extent . If it is less then complete
malocclusion will be more fully expressed but less severe than
the tendencies otherwise could produce.
www.indiandentalacademy.com
7. HEAD FORM & MALOCCLUSION
TENDENCIES
www.indiandentalacademy.com
8. Shape of the head
There are two basic extremes in the shape of the head
Dolichocephalic
Brachycephalic
The cephalic index is the ratio between overall head length
& breadth: -Dolichocephalic = Upto 75.9%
-Mesocephalic = 76 to 80.9%
-Brachycephalic = Over 81%
www.indiandentalacademy.com
10. Cranial base is flat- flexure between the middle cranial floor &
anterior cranial floor open .
Occlusal plane is rotated downward.
www.indiandentalacademy.com
13. Basicranial floor is more upright and has a more closed flexure
Decreased effective antero-posterior dimension of the middle
cranial fossa
Posterior placement of the maxilla
Horizontal length of the nasomaxillary complex is short.
Retrusion of nasomaxillary complex and more forward
relative placement of mandible.
www.indiandentalacademy.com
14. The resultant profile is prognathic
Class III molar relationship
www.indiandentalacademy.com
15. COUNTERPART PRINCIPLE
Growth of any given facial or cranial part relates
specifically to other structural & geometric "counter
parts" in the face & cranium.
e.g maxillary arch is a counterpart of mandibular arch
If part and counter part enlarge to same extent , balanced
growth is produced.
www.indiandentalacademy.com
17. COUNTERPART ANALYSIS
In this method various facial and cranial parts are compared with
each other.
The individual is measured against himself,rather than compared
with population standards and norms.
Size and alignment of the bones are considered.
Vertical and or horizontal size of one given part is compared with
that of its specific counter parts. If they exactly match, or nearly so ,
a dimensional balance exist between them.
www.indiandentalacademy.com
22. Factors responsible for dentoalveolar
compensatory mechanism
1. Normal eruptive system
2. Soft tissue envelope
3. Influence on tooth exerted by neighboring teeth
during growth
www.indiandentalacademy.com
23. Dentoalveolar compensatory mechanism and
malocclusion
Two main types of malocclusion:
•
Inter arch deviation - occlusion anomalies
•
Intra arch deviation - space anomalies
www.indiandentalacademy.com
24. Three main situations where dentoalveolar compensation is
impaired .
1. An
optimally
functioning
dentoalveolar
compensatory
mechanism
2. In cases where functioning of dentoalveolar mechanism is
incomplete
3. In cases where
for
some reason the compensatory
mechanism is inoperative

26. Horizontal dimension of the mandibular corpus

Mandibular retrusion,
Anterior crowding .
Need not be class II
www.indiandentalacademy.com
27. Mandibular corpus is dimensionally longer

28. Horizontally long nasomaxillary complex
No effect on occlusion
Individual can appear retrognathic – protrusive nature of
upper part of face.
www.indiandentalacademy.com
29. Horizontal dimension of the ramus is narrow relative to
its counterpart-middle cranial fossa
Mandibular retrusive effect.
This is one of basic skeletal cause that underlie a class II molar
relationship
www.indiandentalacademy.com
30. The effective horizontal dimension of the ramus is broad
relative to middle cranial fossa
Mandibular protrusion.
One of the reasons for class III molar relation
www.indiandentalacademy.com
31. Vertically long nasomaxillary complex
Downward and backward rotation
Mandibular retrusion
www.indiandentalacademy.com
33. The Posterior Maxillary Plane
The PM plane is a developmental
interface between the vertical series of
counterparts in front of, and behind it.
This key plane retains these basic
relationships throughout the growth
process.
www.indiandentalacademy.com
34. Neutral Occlusal Axis (N.O.A.):-
In a well balanced face both functional occlusal plane and
N.O.A. will be coinciding.
www.indiandentalacademy.com
35. The alignment of parts are in neutral position.
Occlusal plane is perpendicular to PM plane and parallel to neutral
orbital axis
www.indiandentalacademy.com
36. COMPENSATORY MECHANISM
During the development and establishment of the occlusion,
ongoing and intensive adjustment occurs involving
dentoalveolar remodeling .
The effect of dentoalveolar compensatory mechanism on
dimension of the dental arches ,the inclination of the teeth
and occlusal relationships has been well documented
www.indiandentalacademy.com
38. Nasomaxillary complex lengthened vertically
Mid facial growth has exceeded the growth of ramus and middle
cranial fossa complex
Downward backward alignment of the whole mandible to
accommodate the longer nasomaxillary complex..
www.indiandentalacademy.com
39. Upper teeth drift inferiorly till they contact the antagonist.
Occlusal plane is a straight line , inclined downward.
www.indiandentalacademy.com
40. Dentoalveolar curve (Curve of spee)
Upper teeth drift down . The upper anterior drift only to the level of
the premolar.
Anterior mandibular teeth drift superiorly till they contact the
upper.
Occlusal plane is curved.
www.indiandentalacademy.com
41. ANTERIOR
CROWDING
Teeth have very little capacity to remodel after they are formed
fully. Only a limited extent of root resorption, deposition of
cementum , crown wear are possible in this regard. This means that
adaptive adjustment for a tooth must be carried out by the
displacement process .
www.indiandentalacademy.com
42. While extensive resorptive & depository remodeling is a
basic growth function for the housing alveolar bone, it is
not a factor for the tooth itself . Thus anterior crowding is ,
in effect, a compensatory means by which the teeth are
housed beyond the limit provideded by the alveolar bone .
www.indiandentalacademy.com
43. Compensation for variation in the sagittal jaw
relationship.
• In cases of skeletal class II.
To compensate for the large sagittal discrepancy in jaw
relationship the upper incisor are retroclined and lower incisor are
proclined to maintain normal overjet.
• In cases of skeletal class III.
The upper incisors are proclined and the lower incisors are
retroclined to maintain normal overjet.
(Hiroyaki ishikava et.al)
www.indiandentalacademy.com
44. Compensation for variation in vertical jaw
relationship.
• In cases of skeletal open bite,
To maintain the normal overbite, the posterior dentoalveolar
segment intrudes. The anterior dentoalveolar segment extrudes or
both can happen.
• In a case of skeletal deep bite
The posteriors can extrude or the anteriors can intrude to
maintain a normal overbite.
www.indiandentalacademy.com
45. Compensation for variations in transverse jaw
relationship.
•
A discrepancy between a narrow maxillary base and a
wide mandibular base is compensated by buccal tilting of
upper teeth and lingual tilting of lower teeth.
•
Discrepancy between wide maxillary base and narrow
mandibular base is compensated by lingual tilting of upper
teeth and by buccal tilting of lower teeth.
www.indiandentalacademy.com
46. In ideal situations, this compensation masks discrepancies in
all three planes of space. The dentoalveolar changes may however
also be unfavourable or dysplastic and contribute to an occlusal
problem more severe than that caused by actual
skeletal
discrepancy .
www.indiandentalacademy.com
47. Orthognathic Surgery:-
Every patient who goes for a surgical line of treatment
should be put on an orthodontic appliance to carry out the
presurgical decompensation.
Here upper and lower arches are separately aligned but no
attempt is made to correct the bite by orthodontic means as
bite will be corrected by surgical repositioning of the jaw to
get a near occlusal fit as possible.
www.indiandentalacademy.com
48. INDICATION
FOR
PRE-SURGICAL
ORTHODONTICS
( BELL AND PROFIT )
1 ) When
segments

the
skeletal
cannot
be
&
dento
osseous
placed
a satisfactory
relationship
because of
gross occlusa1
interferences
or
gross malrelation of
teeth to their supporting
bone .
2 ) When postsurgical orthodontic work would
necessitate tooth
www.indiandentalacademy.com
49. What is decompensation?
In many cases of severe jaw imbalances and the resulting
malocclusion, the teeth are inclined in such a manner as to partially
offset the discrepancies.
Pre surgical orthodontics should be aimed at removing this natural
compensation or to decompensate.
www.indiandentalacademy.com
50. NEED FOR PRESURGICAL
DECOMPENSATION
1. To position the teeth in an ideal axial inclination with
respect to the jaws.
2. To optimize the magnitude of surgical advancement
or repositioning.
3. For better esthetics , stability and function.
4. If malpositioned anterior teeth are not corrected , they may
hinder the repositioning of jaws at the time of surgery.
www.indiandentalacademy.com
51. Determination of compensation or
dysplastic development
IN THE MAXILLA, the "maxillary
zone" measured as the angle between the
palatal plane (ANS-PNS) and the maxillary
occlusal plane ( mean 10 +- 3 ), describes
the extent of compensatory or dysplastic
development.
www.indiandentalacademy.com
52. IN
THE
MANDIBLE,
the
"mandibular
zone"
measured between the mandibular plane (Go-Gh)
and the mandibular occlusal plane (mean 20
+-
4)
similarly
describes
possible
compensation.
If
one
or
both
of
these
measurement are increased in a patient
with
increased vertical jaw relations; favourable
dentoalveolar compensation is indicated. On
www.indiandentalacademy.com
53. Dentoalveolar compensation in negative over jet
cases were statistically confirmed for both incisor
inclination and occlusal plane angulation.
However the compensatory effects were weaker
than with positive overjet cases.
