This seminar deals with implant-related complications that lead to implant failure.this also discus diagnostic criteria and preventive methods for an implant failure.
loading protocols in dental implants about indications and contraindications of conventional , immediate,progressive and delayed loading of dental implants
The all-on-6 dental implants procedure is used to replace the entire upper or lower set of teeth. This dental procedure is used to restructure a patient’s mouth, generally done when the patients have lost a significant number of teeth in one or both jaws.
The All-on-6 dental implant procedure creates a permanent prosthesis by using six dental implants. It acts as a support for a bridge or over-denture. Six implants are positioned in the lower or upper jawbone to anchor prosthetic teeth in place permanently.
All-on-6 dental implant offers several benefits such as quick recovery, pearl white smile, no need of removable dentures, patient can bite and chew food, just like natural teeth.

A dental implant (also known as an endosseous implant or fixture) is a surgical component that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, facial prosthesis or to act as an orthodontic anchor. The basis for modern dental implants is a biologic process called osseointegration, in which materials such as titanium form an intimate bond to bone. The implant fixture is first placed so that it is likely to osseointegrate, then a dental prosthetic is added. A variable amount of healing time is required for osseointegration before either the dental prosthetic (a tooth, bridge or denture) is attached to the implant or an abutment is placed which will hold a dental prosthetic.
Success or failure of implants depends on the health of the person receiving the treatment, drugs which affect the chances of osseointegration, and the health of the tissues in the mouth. The amount of stress that will be put on the implant and fixture during normal function is also evaluated. Planning the position and number of implants is key to the long-term health of the prosthetic since biomechanical forces created during chewing can be significant. The position of implants is determined by the position and angle of adjacent teeth, by lab simulations or by using computed tomography with CAD/CAM simulations and surgical guides called stents. The prerequisites for long-term success of osseointegrated dental implants are healthy bone and gingiva. Since both can atrophy after tooth extraction, pre-prosthetic procedures such as sinus lifts or gingival grafts are sometimes required to recreate ideal bone and gingiva.
The final prosthetic can be either fixed, where a person cannot remove the denture or teeth from their mouth, or removable, where they can remove the prosthetic. In each case an abutment is attached to the implant fixture. Where the prosthetic is fixed, the crown, bridge or denture is fixed to the abutment either with lag screws or with dental cement. Where the prosthetic is removable, a corresponding adapter is placed in the prosthetic so that the two pieces can be secured together

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

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.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

• Bone factors
• Loading conditions
• Prosthetic considerations

3. Basic terminology in implantBasic terminology in implant
dentistrydentistry
OSSEOINTEGRATION:
A direct structural and functional
connection between ordered, living bone and the
surface of a load-carrying implant.
(Albrektsson et al. -1981)
ENDOSSEOUS DENTAL IMPLANT:
A device inserted into the jaw bone
(endosseous) to support a dental prosthesis. It is
the ‘tooth root’ analogue and is often referred to as a
‘fixture’. www.indiandentalacademy.com
5. IMPLANT ABUTMENT:
The component which attaches to the
dental implant and supports the prosthesis.
A transmucosal abutment (TMA) is one which
passes through the mucosa overlying the implant.
- a temporary or healing abutment may be used
during the healing of the Peri-implant soft tissue
before the definitive treatment is chosen.
ABUTMENT SCREW:ABUTMENT SCREW:
A screw used to connect an abutment to the
implant.
www.indiandentalacademy.com
7. SINGLE STAGE IMPLANT SURGERY:SINGLE STAGE IMPLANT SURGERY:
surgical placement of a dental implant which is
left exposed to the oral cavity following insertion.
• This is the protocol used in non-submerged implant systems.
TWO STAGE IMPLANT SURGERY:TWO STAGE IMPLANT SURGERY:
Initial surgical placement of a dental implant
which is buried beneath the mucosa and then
subsequently exposed with a second surgical
procedure some months later.
• This is used in submerged implant systems.
www.indiandentalacademy.com
8. Single stage implant surgery
Two stage implant surgery
www.indiandentalacademy.com
10. 1. An individual, unattached implant is immobile when tested
clinically.
2. Radiographic examination does not reveal any Peri-
implant radiolucency.
3. After the first year in function, radiographic vertical bone
loss is less than 0.2mm per annum.
4. The individual implant performance is characterised by an
absence of signs and symptoms such as pain, infections,
neuropathies, paraesthesia, or violation of the inferior
dental canal.
5. As a minimum, the implant should fulfill the above criteria
with a success rate of 85% at the end of a 5yr observation
period and 80% at the end of a 10yr period.
Albrektsson et al. IJOMI 1986;1:11
www.indiandentalacademy.com
11. • However, some of the criteria apply to the overall
requirements of an implant system, but are not
useful when judging the success of individual
implants.
• The ideal bone level is usually judged against a
specific landmark on the implant and it may differ
therefore between implant systems.
• The bone levels are usually more or less stable,
and small changes such as 0.2mm per annum are
impossible to measure with conventional
radiographs.
www.indiandentalacademy.com
12. • It is also difficult to stipulate what level of change in
an individual implant over a given period of time
would constitute failure.
• A rapid change in bone level may be followed by a
long period of stability.
• On the other hand progressive or continuous bone
loss is a worrying sign of impending failure.
• Implants placed in the mandible have a higher
success rate than the maxilla.
95% - mandible (after 5yrs of loading)
85%-90% - maxilla
www.indiandentalacademy.com
14. • Biocompatibility and implant design
• Bone factors
• Loading conditions
• Prosthetic considerations
www.indiandentalacademy.com
15. Biocompatibility and implantBiocompatibility and implant
designdesign
• Successful clinical results are reported in
implants, made up of commercially pure
titanium, titanium alloys, hydroxyapatite coated
implants, and few others like niobium.
• More recently resorbable coatings have been
developed for improving initial rate of bone
healing against the implant surface and then
resorb within a short time frame to allow
establishment of a bone to metal contact.
www.indiandentalacademy.com
16. Implant designImplant design
• Has a great influence on initial stability and
subsequent function.
• The main design parameters are…
• implant length
• Implant diameter
• Implant shape
• Surface characteristics
www.indiandentalacademy.com
17. Implant lengthImplant length
• Generally available in lengths from about
6mm to as much as 20mm.
• Most common lengths employed are
between 8 and 15mm which correspond
quite closely to normal root lengths.
www.indiandentalacademy.com
18. Implant diameterImplant diameter
• Most implants are approx. 4mm in diameter.
At least 3.25mm in diameter is required to
ensure adequate implant strength.
• Important in the distribution of loads.
• Up to 6mm are available, which are
considerably stronger, but they are not so
widely used because sufficient bone width is
not so commonly encountered.www.indiandentalacademy.com
19. ImplantImplant
shapeshape
• Hollow-cylinders, solid-cylinders, hollow screws or
solid screws are commonly employed shapes.
• Are designed to maximize the potential area for
osseointegration and provide good initial stability.
• Screw shaped implants also offers good load
distribution characteristics in function.

21. Surface characteristicsSurface characteristics
• The degree of surface roughness varies
greatly between different systems.
• Surfaces which are machined, grit-blasted,
etched, plasma sprayed and coated are
available.
• By increasing the surface roughness there is
the potential to increase the surface contact
with bone but this may be at the expense of
more ionic exchange and surface corrosion.www.indiandentalacademy.com
23. BONE FACTORS
• Radiographic determination of bone quantity and quality
should be considered.
• The most favourable quality of jaw bone for implant treatment
is that which has a well formed cortex and densely trabecular
medullary spaces with a good blood supply.
• cortical bone – initial stability, but easily damaged by
overheating during drilling. (especially sites more than 10mm
in depth)
• Thin Cortical layer and sparse trabeculation – poor initial
stability & fewer cells with good osteogenic potential to
promote osseointegration.
www.indiandentalacademy.com
25. Factors which compromise bone quality
are…
• Infection
• Irradiation
• Heavy smoking
• The effects of the latter two are a result of a
diminution of the vascular supply to the bone which
compromises the healing response.
www.indiandentalacademy.com
26. LOADING CONDITIONSLOADING CONDITIONS
• Following installation of an implant it is important
that it is not loaded during the early healing phase.
• Movement of the implant within the bone at this
stage results in fibrous tissue encapsulation rather
than osseointegration.
• Currently there is no accurate measure which
precisely determines the optimum period of
healing before loading can commence.
www.indiandentalacademy.com
27. • Bone quality can be assessed by measuring
the cutting torque during preparation of the
implant site.
• The stability of the implant and increasing
bone-to-implant contact has been quantified
using Resonance frequency analysis.
• This non-invasive research tool measures
stiffness of the implant at the bone interface.
www.indiandentalacademy.com
28. • Some systems employ a single stage
approach in which the implant is installed so
that it protrudes through the overlying
mucosa (i.e non-submerged), although
evidence of early loading is equally critical.
• Following the recommended healing period,
abutments are connected to the implant to
allow construction of the prosthesis.
www.indiandentalacademy.com
29. Prosthetic considerationsProsthetic considerations
• Carefully planned functional occlusal loading will
result in maintenance of osseointegration and
possibly increased bone to implant contact.
• In contrast, excessive loading may lead to bone
loss and/or component failure.
• Clinical loading conditions are largely depend
upon :
• The type of prosthetic reconstruction
• The occlusal scheme
• The number, distribution, orientation and design of implants
• The design and properties of implant connectors
• Dimensions and location of cantilever extensions
• Patient parafunctional activities
www.indiandentalacademy.com
30. The type of prosthetic reconstructionThe type of prosthetic reconstruction
• This can vary from a single tooth replacement in
the partially dentate case to a full arch
reconstruction in the edentulous individual.
• Implants which support overdentures may
present particular problems with control of
loading as they may be largely mucosal
supported, entirely implant supported or a
combination of the two.
www.indiandentalacademy.com
31. The occlusal schemeThe occlusal scheme
• The lack of mobility in implant supported fixed prostheses
requires provision of shallow cuspal inclines and careful
distribution of loads in lateral excursions.
• With single tooth implant restorations it is important to
develop initial tooth contacts on the natural dentition and to
avoid guidance in lateral excursions on the implant
restoration.
• Loading will also depend upon the opposing dentition which
could be natural teeth, another implant supported
prosthesis or a conventional removable prosthesis.
www.indiandentalacademy.com
32. The number, distribution, orientationThe number, distribution, orientation
and design of implantsand design of implants
• The distribution of load to the supporting bone can
be spread by increasing the number and
dimensions (diameter, surface topography, length)
of the implants.
• The spacing and 3-dimensional arrangement of
the individual implants will also be very important.
• The so-called ‘tripod’ arrangement of three
implants is recommended in situations of high
load, such as replacement of molar teeth in the
partially dentate individual.www.indiandentalacademy.com
33. The design and properties of implantThe design and properties of implant
connectorsconnectors
• Multiple implants are joined by a cast or milled
framework.
• A rigid connector provides good splinting and
distribution of loads between implants.
• It is equally important that the connector has a
passive fit on the implant abutments so that the
loads are not set up within the prosthetic
construction.

34. Dimensions and location of cantileverDimensions and location of cantilever
extensionsextensions
• Cantilever extensions have the potential to create
high loads, particularly on the implant adjacent to
the cantilever.
• The extent of the leverage of any cantilever
should be considered in relation to the
anteroposterior distance between implants
supporting the reconstruction.
• The cantilever extension should not exceed this
length and cross sectional design should be
adequate to prevent flexing.

35. Patient parafunctional activitiesPatient parafunctional activities
• Great caution should be exercised in treating
patients with known parafunctional activities.
• Excessive loads may lead to loss of marginal
bone or component fracture.

36. There are great many factors to take into
account to ensure predictable successful
implant treatment.
There is no substitute for meticulous
attention to detail in all of these areas.
Failure to do so will result in higher failure
rates and unnecessary complications.
