“The study of orthodontia is indissolubly connected with that of art as related to the human face.” -Dr. Edward H. Angle.
Each person shares with the rest of the population a great many characteristics, but there are enough differences to make each human being a unique individual. Such limitless variation in the size, shape and relationship of the dental, skeletal and soft tissue facial structures are important in providing each individual with his or her own identity.
Face – Difficult object to measure accurately because of
– complex morphology
– sensitivity to eyes
– its soft nature.
One of goals of orthodontic treatment is creating a balanced & harmonious facial appearance. Craniofacial symmetry is one of the aspect of this harmony. Subject of symmetry or lack of symmetry of human face has been of considerable interest, particularly in the field of Orthodontics. Minor variation is a desirable variation of craniofacial structure which is perceived as esthetically pleasing and has no esthetic or functional significance. Asymmetry becomes important when it affects the function or esthetics of the person.

examination of open bite
treatment of open bite
etiology of open bite
II- Clinical examination
a- Extra-oral:
1- Dental open bite: patient with dental open bite often have normal facial proportion
2- Skeletal open bite: patient with skeletal open bite often show the following:
- Narrow and long face
- Slim nose with narrow nasal slits
- Incompetent lips, short upper lip and hyperactive lower lip
- Shallow labio-mental sulcus
- Excessive upper incisors show, and gummy smile
- Increase lower third of the face
- Receded chin point
- Increase inter-labial gap
- Steep mandibular plane
- Excessive anti-gonial notch
- Short ramus
b- Intra-oral examination:
1- Dental open bite: may be associated with:
= proclination of upper and lower incisors and open bite not more than 1mm ------ pseudo open bite
= localized open bite confined to one or two teeth ------ mechanical interference by nail biting or putting something between the teeth, lead to attrition at incisal edge
= well circumscribed open bite confined to the anterior region associate with history of thumb sucking -------- adaptive tongue thrust
= clinical crown of anterior teeth is short
2- Skeletal open bite:
May be associated with the following:
- Will circumscribed open bite extending to the 1st molars
- Ill-defined open bite extending to the last occluding molars
- Poor inter-cuspation
- Collapsed maxilla and buccal cross bite
- Anterior teeth may be extruded
- The posterior dentoalveolar segment is over-developed
III- Study cast
1- Anterior posterior relationship:
= anterior open bite rarely presented as a separate or isolated entity but may be associated with class I, II, III relationship
= the upper incisors are proclined, while the lower incisors often retroclined by the action of lower lip
= crowding is common finding in lower incisors, while the upper incisors may or may not show crowding
= as a general, dental open bite is frequently associated with Class I skeletal base and good intercuspation while skeletal open bite may be associated of skeletal anterior posterior dysplasia and poor intercuspation.
2- Vertical analysis:
= in dental open bite, the clinical crown of the anterior teeth is short, the anterior teeth lack vertical development due to mechanical interference or disturbance in eruption
= the vertical height of posterior teeth is normal
= in skeletal open bite: the anterior teeth may be extruded and there is excessive posterior dental alveolar development. The curve of spee is reversed
3- Transverse analysis:
Dental open bite has no discrepancy in lateral direction while skeletal open bite may be associated with collapsed maxilla and buccal cross bite
IV- Cephalometric analysis
1- Anterior posterior:
Dental open bite is most frequently associated with skeletal class I while skeletal open bite is most commonly associated with skeletal class II or class III skeletal pattern
2- Vertical cephalometric analysis:

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

3. 1- Introduction - Definition
Anterior open bite (AOB) is generally defined as a condition where the upper incisor crowns fail to
overlap the lower incisor crowns when the mandible is brought into full occlusion.
A ope ite ould ra ge fro a ild ase of edge to- edge i isor relatio ship to a severe skeletal ope
bite with only the molars in contact.
Simple open bites are usually confined to the teeth and alveolar process where as complex openbites
are based primarily on vertical skeletal dysplasias..

4. 2-Open bite Classification
Dentoalveolar open bite (Functional) Anterior open bite Open bite - Deciduous teeth
Skeletal Open Bite (Hereditary ) Posterior Openbite Openbite-Permanent teeth
5. 3-Prevalence Openbites
• The prevalence of skeletal long face malocclusion is unknown, but has been estimated to be 0.6% or
1,350,000 U.S. citizens.
• The prevalence of dental open bites in U.S. children is approximately 16% in the black population and
4% in the white population,
• All children experience anterior open bites during the transition from the primary to permanent
dentitions
Peter Ngan, Henry W. Fields, American Academy f Pediatric Dentist, Pediatric D entistry1- 9:2, 1997
6. 4-Problems related to Openbite
- Masticatory (1) and speech (2) is problems have been attributed to open bites.
-The inability to incise is the chief complaint (3) often voiced by open bite patients.
-Other patients indicate displeasure with their facial esthetics and smile (4).

7. 5-Etiologic Factors
• Because of their multifactorial etiologies, dental and skeletal open bites are
among the most difficult malocclusions to treat to a successful and stable result.
• Etiologic factors include vertical maxillary excess, skeletal pattern, abnormalities
in dental eruption, and tongue-thrust problems, any other malocclusion, can be
either hereditary or environmental in origin
• 1. Heredity
• 2. Environmental Factors
• a-Thumb, finger or foreign body sucking
• b- Abnormal tongue function.
• c -Airway pathology.
• d- Iatrogenic factors, e.g. extruding molars during treatment
• e- Trauma or pathology to one or both condyles
• f- Orofacial Muscules Dysfunction

8. 1- Genetics Factors – Open bite
Skeletal growth abnormalities- Hyperdivergent Skeletal Pattern
The patient may often has a long and
narrow face.
-Divergent cephalometric planes
-Steep anterior cranial base
-Downward and forward rotation of
the mandible.
-Vertical maxillary increase
-Increased lower anterior facial
height
-Decreased upper anterior facial
height
-Increased anterior and decreased
posterior facial height
-A steep mandibular plane angle
-Small mandibular body and ramus
-The patient may have short upper lip
with excessive maxillary incisor
exposure
9. 2-Environmental Factors
a- Thumb and finger sucking or pacifier use
In younger children, the major cause of anterior open bite (excluding open bites associated with the
transition from the primary to mixed dentitions) are
non-nutritive sucking habits.
By adolescence, environmental causes of anterior open bite are less important than skeletal factors.
A surprisingly large percentage (10-15%) children continue to suck a thumb, finger, or other object well into
the elementary school yea.

aetiology, eg. Thumb sucking, tongue function/posture. The openbite is generally confined to the
incisor region and maybe asymmetric. In cases of digit sucking the maxillary arch may also be narrow
with proclination of the upper incisors and retroclination of the lower incisors. In patients with a
forward tongue posture proclination and spacing of the upper and lower incisors is often seen,

19. 6-Dental Openbite - Skeletal Open Bite
-Studies have indicated that skeletal open bites are often
related to excessive vertical growth of the dentoalveolar
complex, especially in the region of the posterior maxillary
molar .
- Conversely, dental anterior open bites are primarily due
to reduced incisor dentoalveolar vertical height .
The difference between these two types of open bites is
also reflected in the occlusal planes. The skeletal type of
malocclusion generally has occlusal contacts only at the
molar level, with both occlusal planes diverging
anteriorly,whereas the occlusal planes in the dentoalveolar
open bite usually diverge from the first premolar forward

24. The Percentages of occurrence of dental components in
open bite malocclusion
Dental components: The flattened curve of Spee showed
the highest contribution in open bite malocclusion (73.4%)
followed by the proclination of the upper incisors (65.8%),
under-eruption of the lower incisors (31.6%), proclination
of the lower incisors (26.6%), lower incisors decreased
clinical crown length (24.1%), the decreased clinical crown
length of the upper incisors (20.3%), the under-eruption of
the upper incisors (6.3%). The least contributing factors in
open bite malocclusion were the over-eruption of the
upper posterior segment (1.3%), and the over-eruption of
the lower posterior segment (1.3%)
25. The percentages of occurrence of skeletal components in
open bite malocclusion
Skeletal components: The steep mandibular plane angle was found
to be the most skeletal component contributing to open bite
malocclusion (72.2%) followed by the increased gonial angle(59.5%),
and the least sharing skeletal component was maxillary plane
counter clock-wise rotation (38%) .
The mean of "Ramus/FH" was found to be 82.06 ± 5.14 in open bite
cases, representing the mean of the angulation of the mandibular
ramus in open bite malocclusion.

Achieving an ideal treatment outcome depends on an accurate diagnosis in three dimensions, a
good understanding of the interaction between the neuromuscular components of the orofacial
region and the craniofacial skeleton, vertical maxillary excess, vertical facial pattern, and the ability
to provide individualized treatment mechanics.

33. 7c-Treatment of Thumb-Sucking or Finger-Sucking
Ravindra Nanda, Flavio Andres Uribe, Nandakumar Janakiraman
http://pocketdentistry.com/9-management-of-open-bite-malocclusion-2/
Children should be encouraged by
their parents to stop the sucking
habit before the age of 4 years.
Before this age, most adverse dental
and skeletal effects caused by the
habit usually return to the original
state, creating a favorable
environment for the eruption of
permanent teeth.
To help a child stop the habit,
parents should note the time of the
day at which the behavior occurs
and then try to intervene. For
example, if a child sucks a thumb or
finger during sleep, mechanically
obstructing the hand with a sleeping
gown may be helpful.
If initial attempts are unsuccessful,
an intraoral appliance that acts as a
mechanical obstruction and
reminder can be used.
Tongue Crib

Ravindra Nanda, Flavio Andres Uribe, Nandakumar Janakiraman
http://pocketdentistry.com/9-management-of-open-bite-malocclusion-2/
Patients with tongue thrusting can be treated
effectively in the same manner as that used for
patients who suck on a thumb or finger
,although different appliances, such as the
habit appliance with lingual spurs or cribs ,
have been suggested, In one
study, immediately after crib placement the tip
of the tongue was positioned posteriorly
during all stages of deglutition.
This altered tongue posture aided in the
correction of an anterior open bite through an
increase in overbite of 3.6-mm.
Tongue spurs
35. 7d-Dental Openbite Treatment with elastics
Ravindra Nanda- http://www.orthodonticproductsonline.com/2011/07/open-bite-correction-2011-07-03/
For mild open-bite malocclusions (1 to 3 mm), placing step bends and meticulous bracket positioning
can help reduce the open bite
without any significant side effects. In this patient, the anterior brackets were placed more gingivally
as compared to the
posterior brackets, to aid in correction of the open
Anterior elastics
36. 7-Bracket placement for treatment of open bites
In patients with open bite, the bracket height for the maxillary
anterior teeth, which are out of occlusion, is increased by 0.5
mm. The bracket height for posterior teeth, which are in
occlusion, is decreased by 0.5 mm , The amount of curve of
Spee in the mandibular arch can be used to determine if any
change in bracket height is necessary. If there is significant
reverse curvature to the mandibular occlusal plane, then the
bracket heights are adjusted in both the maxillary and the
mandibular arches.

The Fisher BCA (Bite Closing Appliance) is a maxillary appliance designed to close an open bite by
intruding over- erupted posterior teeth, This appliance, utilizes a bonded posterior bite plate fitted
with 4 special ball-end hooks which attach with closed coil springs to TADS (temporary anchorage
devices) placed in the zygomatic process, When anchored against the TADS the force of the closed
coil springs on the posterior bite plate is directed in a superior direction affecting the intrusion of
posterior teeth., A rapid palatal expansion option is available. Transpalatal wires (or RPE screw) are
positioned a minimum of 5 mm off of the palate to allow for intrusion

Procedures that promote better breathing through the nose (turbinate surgery, adenoid and tonsil
removal, allergy treatment) may help to reestablish normal growth patterns. However, the growth
direction of the mandible among patients varies greatly after any of these procedures. This
variability makes the decision to intervene with a resective surgical procedure difficult. Therefore
the diagnosis of upper airway obstruction and the decision for surgical intervention should always
be made by an appropriate team of specialists.

Using reverse-curved archwires to close an anterior open bite. The strong anterior box elastics
prevent the premolars from erupting, while the molars intrude and tip back and the incisors

dependent on patient cooperation. Elastics must be worn all day, otherwise the bite may open
with quick extrusion of the premolars.

63. 8-Open bite: stability-
Tongue posture and a hyperdivergent facial growth
Marise de Castro Cabrera, Carlos Alberto Grego´ rio Cabrera, Karina Maria Salvatore de Freitas, (Am J Orthod Dentofacial
Orthop 2010;137:701-11)
The difficulties encountered in obtaining
stable results for AOB correction can be
justified by the fact that their true
etiology still defies understanding.
Reassess whether or not tongue posture
and a hyperdivergent facial growth can
be considered as an etiological factor of
AOB.
There is more than one possible resting
position for the tongue. It can position
itself on a higher or lower level,
producing open bite with different
morphological characteristics and
severity.
Once the posture of the tongue has been
corrected, the etiological factor is
extinguished and treatment stability is
ensured.
Appropriate treatment should be
selected based on these characteristics,
and can be conducted by either
restraining or orienting the tongue
Classification for posture of the
tongue at rest: (A) Normal, (B) high, (C) horizontal,
(D) low and (E) very low.
