This document defines and describes different types of crossbites, including buccal, lingual, palatal, unilateral, bilateral, functional lateral, complete mandibular, complete maxillary, scissor bite, anterior, and posterior crossbites. It discusses the prevalence, etiology, diagnosis, and treatment of crossbites, which can include the use of inclined bite planes, rapid palatal expanders, and slow palatal expanders in younger patients, and transverse maxillary expansion in older patients. Left untreated, crossbites can cause complications like growth modifications, dental compensations, condylar deviation, and TMJ issues.
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.
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

Embracing GenAI - A Strategic ImperativePeter 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.
Power-sharing Class 10 is a vital aspect of democratic governance. It refers to the distribution of power among different organs of government, levels of government, and social groups. This ensures that no single entity can control all aspects of governance, promoting stability and unity in a diverse society.

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 Art Pastor's Guide to Sabbath | Steve ThomasonSteve Thomason
What is the purpose of the Sabbath Law in the Torah. It is interesting to compare how the context of the law shifts from Exodus to Deuteronomy. Who gets to rest, and why?
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
6. • It’s a condition where one or more teeth may be
abnormally malposed buccally or lingually or labially
with reference to the opposing tooth or teeth –Graber
• Discrepancy in the buccolingual relationship of the
upper and lower teeth –Laura
• An abnormal buccolingual (labiolingual) relationship
of the teeth –Moyer
• Post X-bite: Deviation from ideal occlusion in the
transverse plane of space. -Proffit
13. FUNCTIONAL LATERAL CROSSBITE
• Caused by an occlusal interference that
requires the mandible to shift either
anteriorly or laterally in order to achieve
maximum occlusion
14. • COMPLETE MANDIBULAR CROSSBITE
When all the mandibular teeth are buccally
positioned to all the maxillary teeth if the
mandibular arch is wide
• COMPLETE MAXILLARY CROSSBITE
When the maxillary dental arch is wide
15. COMPLETE CROSSBTE
when all teeth in one arch are positioned either
inside or outside to the all teeth in the opposing
arch.
16. SCISSOR BITE
is present when one or more of the adjacent posterior teeth are
either positioned completely buccally or lingually to the antagonistic
teeth and exhibit a vertical overlap.
e.g: brodie syndrome, pierre robin syndrome---primary,mixed!
Chewing,muscle,normal growth of Mn.
17. ANTERIOR CROSSBITE
A malocclusion in which one or more of the upper
anterior teeth occlude lingually to the mandibular
incisors; the lingual malpositions of one or more
maxillary anterior teeth in relation to the
mandibular anterior teeth when the teeth are in
centric relation occlusion
18. This is when the upper incisors are in reverse overjet and occlude lingual to the
lower incisor. An example of this would be an extreme class III incisor relationship.
19. POSTERIOR CROSSBITE
When one or more posterior teeth locked
in an abnormal relation with the opposing
teeth of the opposite arch; can be either
buccal or a lingual cross-bite and may be
accompanied by a shift of the mandible.
44. II- MIXED DENTITION
•
•
•
•
•
Rationale for Early Interceptive Treatment:
Little possibility for self-correction
To save permanent dentition.
Postponing Rx---greater complexity
Can cause growth modifications and dental
compensations
• Permanent deviation & craniofacial asymmetry &
masticatory patterns
• Condylar deviation & TMJ sounds
45. • Interference with growth of the middle third
of the face
• Abnormal speech patterns
• Loss of arch integrity
• Periodontal disease
• Undesirable esthetics
• Root resorption of central incisors
46. • Those that deliver rapid-heavy-intermittent
forces:
• Fixed inclined bite planes
• Constructed of acrylic
• Placed onto the mandibular incisors
• Treat lingually locked maxillary incisors
• Do not require patient compliance
• May open the bite, create a temporary
• speech defect, or traumatize the dentition
• No significant long-term side effects
47.
48. • Reversed stainless steel crowns
• Anterior stainless steel crowns cemented
backwards on the maxillary teeth
• Stainless steel crown needs to open the bite 2 to
3 mm and establish at least a 25 percent
overbite for successful treatment
• If they worsen or fail to treat the crossbite, add
crown
49.
50. • Tongue Blades
• Usually employed as a follow up to treatment
with inclined plane
• Simplest but least successful approach
• Works best if the bite is normal and the involved
tooth is newly erupted
51.
52. PERMANENT DENTITION
• Individual teeth displaced into anterior
crossbite
• Transverse maxillary expansion by opening the
midpalatal suture
56. RAPID PALATAL EXPANSION
-Activation is 0.5 mm per day
i.e. 2 turns for the screw
-force is 10-20 lbs of forces
applied
-Forces transmitted on suture
SLOW PALATAL EXPANSION
-Activation is 1mm per
week
-2lbs pressure applied
-less pressure to teeth and
sutures
58. • Movement of the lateral and medial
poles of the working condyle during
mastication in patients with unilateral
posterior crossbite
• condylar movements in patients with
unilateral posterior crossbites might be
related to the susceptibility to TMJ disc
displacement
59. • Ultrasonographic Thickness of the Masseter
Muscle in Growing Individuals with Unilateral
Crossbite
• The masseter muscle in untreated individuals with
unilateral crossbite is thinner in the crossbite side
when compared to the non-crossbite side possibly
due to asymmetric activity of the masticatory
muscles. Such an asymmetry in thickness of the
masseter muscle could not be detected some years
after the successful correction of the crossbite.
