Over time, progressively shorter implants have been placed such that short implants are now available that are less than 6 mm in length. The viability and high success rates seen with short implants can be explained by osseointegration, the macro geometric design of the implant, as well as physics and the distribution of forces. This paper was aimed to review the stability and survival rate of short implants under functional loads. Numerical and clinical studies were reviewed.

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.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

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”.

4. A SCIENTIFIC RATIONALE FOR ROOT
FORM DENTAL IMPLANT DESIGN
Dental implants function to transfer load to surrounding biologic
tissues. Thus the primary functional design objective is to manage
(dissipate and distribute) biomechanical load to optimize the implant
supported prosthesis function.
Biomechanical load management is dependent on two factors:
the character of the applied force and
the functional surface area over which the
load is dissipated.
www.indiandentalacademy.com
5. CHARACTER OF FORCES
APPLIED TO DENTAL IMPLANTS
Stress and strain have been shown to be important parameters for
crestal bone maintenance and implant survival. These factors may be
measured and compared for different implant body designs.
Forces applied to dental implants may be characterized in terms of
five distinct, although related, factors : magnitude, duration, type,
direction, and magnification. Each factor must be carefully
considered, with appropriate weight, in the critical analysis of implant
design.
www.indiandentalacademy.com
6. 1. Force Magnitude
Forces in molar, premolar and canine.
Titanium alloy
Commercially pure titanium
Density of bone.
www.indiandentalacademy.com
7. 2. Force Duration
Swallowing and eating
Bruxism
High stress
www.indiandentalacademy.com
8. 3. Force Type
Physiologic Constraints on Design
Three types of forces may be imposed on dental implants within
the oral environment: compression, tension, and shear. Bone is
strongest when loaded in compression, 30% weaker when
subjected to tensile forces, and 65% weaker when loaded in
shear .
Endosteal root-form implants load the bone-to-implant interface
in pure shear (e.g., a smooth sided cylinder) unless surface
features are incorporated in the design to transform the shear
loads to more resistant force types.
www.indiandentalacademy.com
9. Influence on Implant Body
Design
A smooth cylinder implant body results
in essentially a shear type of force at the
implant-to-bone interface. Thus this
body geometry must use a microscopic
retention System by coating the implant
with titanium or hydroxyapatite.
Threaded implants have the ability to transform
type of force imposed at the bone interface
through careful control of thread geometry.
Thread shape is particularly important in
changing force type at the bone interface.
www.indiandentalacademy.com
10. Thread shapes in dental implant designs includes :
square
V-shape
buttress
www.indiandentalacademy.com
11. 4. Force Direction
Physiologic Constraints on Design
The anatomy of the mandible and maxilla places significant
constraints on the ability to surgically place root form implants
suitable for loading along their long axis. Resorptive patterns
following prolonged edentulism exacerbates the normally
occurring angulation challenges .
Bone is strongest when loaded in its long axis in both
compression or tensile forces. A 30-degree offset load reduces the
compressive strength of bone by 11%, and reduces the tensile
strength by 25%.
www.indiandentalacademy.com
12. Influence on Implant Body Design
As the angle of load increases, the stresses around the implant
increase, particularly in the vulnerable crestal bone region. As a
result, virtually all implants are designed for placement
perpendicular to the occlusal plane. This placement allows a
more axial load to the implant body and reduces the amount of
crestal stress. Additionally, axial alignment places less stress on
the abutment components and decreases the risk of short- and
long-term fracture.
www.indiandentalacademy.com
13. The face angle of the thread can change the direction of load from
the prosthesis to abutment connection, to a different force direction
at the bone.
As a result, the axial load on the implant
platform may be a compressive load, but
the 30-degree angle of the V -shape
thread can reduce the amount of load the
bone interface is able to resist.
The power thread design can take the
axial load of the prosthesis to abutment
connection and transfer a more axial load
along the implant body to compress the
bone, rather than convert it to 10 times
more shear.
www.indiandentalacademy.com
14. 5. Force Magnification
A surgical placement resulting in extreme angulation of the implant
and/or a patient exhibiting parafunctional habits will likely exceed the
capability of any dental implant design to withstand physiologic loads.
Cantilevers and crown heights act as levers and therefore are, force
magnifiers.
Careful treatment planning with special attention to the use of multiple
implants to increase functional surface area is indicated when a clinical
case presents the challenge of force magnifiers.
www.indiandentalacademy.com
15. Surface area
For a given bone (and implant) volume, implant surface area must
be optimized for functional loads.
Thus an important distinction is made between total surface area
and functional surface area.
Functional surface area is defined as the area that actively serves
to dissipate compressive and tensile non-shear loads through the
implant-to-bone interface and provide initial stability of the implant
following surgical placement.
Total surface area may include a "passive" area that does not
participate in load transfer
For example, plasma spray coatings are often reported to provide'
up to 600% more total surface area however, the amount of area
that is actually exposed to bone for compressive or tensile loading
may be less than 30% of the total surface area.
www.indiandentalacademy.com
16. Design Variables in Surface Area
Optimization
Implant Macro geometry
Smooth-sided, cylindric implants provide ease in surgical
placement however; the bone-to-implant interface is subjected to
significantly larger shear conditions.
In contrast, a smooth-sided, tapered implant allows for a
component of compressive load to be delivered to the bone-to-
implant interface, dependent upon the degree of taper.
www.indiandentalacademy.com
17. Implant Width
Over the past five decades of endosteal implant history, implants
have gradually increased in width.
Today, dental implants generally have reflected the scientific principle
that an increase in implant width adequately increases the area over
which occlusal forces may be dissipated. For root form implants of
circular cross-section, the load bearing area of the abutment platform
increases as a function of the radius squared.
A 4-mm root form implant has 33% greater surface area than a 3-
mm root form implant.
www.indiandentalacademy.com
18. Thread Geometry
Functional surface area per unit length of the implant may be
modified by varying three thread geometry parameters:
Thread pitch,
Thread shape
Thread depth.
www.indiandentalacademy.com
19. Thread Pitch is defined as the distance measured parallel with its
axis between adjacent thread forms
Or the number of threads per unit length in the same axial plane and
on the same side of the axis
www.indiandentalacademy.com
20. The thread shape is another very important characteristic of overall
thread geometry. As described previously, thread shapes in dental
implant designs include:
Square
provides an optimized surface area for
intrusive, compressive load
transmission
V-shape
the V -thread design is called "fixture"
and is primarily used for fixturing
metal parts together-not load transfer.
Buttress
is optimized for pullout loads
www.indiandentalacademy.com
21. Differences in shear loading on the standard V-
thread and the square thread
V-thread has 10 times greater
shear loads on bone compared
with a square thread
The reduction in shear loading at
the thread-to-bone interface
provides for more compressive
load transfer, which is particularly
important in compromised D3 and
D4 bone.
www.indiandentalacademy.com
22. The thread depth refers to the distance between the major and
minor diameter of the thread.
Conventional implants
provide a uniform thread
depth throughout the
length of the implant.
This unconventional design
feature results in dramatic
increases in functional
surface area at the crest
of the bone, where the
stresses are highest.
www.indiandentalacademy.com
23. As the length of an implant increases, so does the overall total surface
area. As a result, a common idea has been to place an implant as long
as possible preferably, into the opposing cortical plate.
Attempting to engage the opposing cortical plate and preparing a
longer osteotomy may result in overheating the bone.
Longer implants have been suggested to provide greater stability
under lateral loading conditions.
Studies have shown that the highest stresses were observed in the
crestal bone regions, regardless of the implant length.
This biomechanical analysis supports the opinion- that longer implants
are not necessarily better.
Instead, there is a minimum implant length for each bone density,
depending on the width and design.
The softer the bone, the greater the length suggested.
Implant Length
www.indiandentalacademy.com
24. Crest Module Considerations
The crest module of an implant body is the transosteal region from
the implant body and characterized as a region of highly
concentrated mechanical stress.
Instead, it is a transition zone to the load-bearing structure of the
implant body
In. fact, bone loss has been observed so often, many implant crest
modules are designed to reduce plaque accumulation once bone loss
has occurred
www.indiandentalacademy.com
25. A smooth, parallel-sided crest module
will result in shear stresses in this
region, making maintenance of bone
very difficult.
An angled crest module of more than
20 degrees, with a surface texture
that increases bone contact, will
impose a slight beneficial compressive
component to the contiguous bone
and decrease the risk of bone loss.
www.indiandentalacademy.com
26. Apical Design Considerations
Most root form implants are
circular in cross-section. This
permits a round drill to
prepare a round hole,
precisely fitting the implant
body.
Round cross-sections,
however, don’t resist
torsional/shear forces when
abutment screws are
tightened or when free-
standing, single tooth implant
receive a rotational (torsional)
force.
The apical end of each
implant should be flat rather
than pointed. www.indiandentalacademy.com
27. As a result, an anti-rotational feature is
incorporated, usually in the apical region of
the implant body, with a hole or vent being
the most common design.
The apical hole region may also increase the
surface area available to transmit compressive
loads on the bone.
www.indiandentalacademy.com
28. Surface Coatings
Titanium Plasma Spray
Hydroxyapatite Coatings
The clinical advantages of TPS or HA coatings may be summarized
as the following:
Increased surface area ( can be up to 600%)
Increased roughness for initial stability
Stronger bone-to-implant interface
Additional advantages of HA over TPS include the
following:
Faster healing bone interface
Increased gap healing between bone and HA
Stronger interface than TPS
Less corrosion of metal
www.indiandentalacademy.com
29. Disadvantages of coatings include
1. Flaking, cracking, or scaling upon insertion
2. Increased plaque retention when above bone
3. Increased bacteria and nidus for infection
4. Complication of treatment of failing implants
5. Increased cost
www.indiandentalacademy.com
31. The present designs fall into four morphological
categories:
Screw or Threaded
Bullet or Conical
Basket or Vented
Fin or Plateau
Others are:
Titanium plasma sprayed screw implant system
Cylindrical Hydroxyapatite coated implant
Grooved Hydroxyapatite coated cylinder
Vitreous carbon implants
www.indiandentalacademy.com
32. Screw root forms are threaded into bone
site and have macroscopic retentive elements for initial
bone fixation. Screw type of implants have been used for
more than two decades.
Earlier placement technique resulted in traumatic site
preparation of bone and immediate or early loading of the
implant that interfered with bone healing.
Branemark showed 2 keys to predictable screw implant
technique and success: avoid traumatizing and
overheating the bone during site preparation and allow
adequate time for bone healing. Almost all commercially
available screw-type implant systems recommend not to
loading the implant for several months to allow
osseointegration to occur.
The only system that still recommends immediate loading
of the implants is the titanium plasma sprayed screw
system (TPS screws).
Different surface finishes range from machine tooled, sand
blasted, acid etched, to hydroxylapatite coated; an implant
design can range from self tapping to those needing
threads cut into the bone.www.indiandentalacademy.com
34. Cylindrical Basket
The hollow basket design provides nearly twice the bone contact of a
solid cylinder of the same length and diameter.
The receptor site is prepared with trephines, producing minimal bone
destruction and leaving a vital bone core over which the implant is
seated.
Perforations in the cylinder walls enable bone growth through the
implant to increase stability and improve load distribution.
Titanium or titanium alloy is used, permitting osseointegration. The
fenestrated hollow-cylinder design minimizes stresses within the implant
on vertical loading and providing a greater area for load transmission to
the surrounding bone.
Two system currently incorporate the hollow-basket concept:
The ITI implants
The Core-Vent implant
www.indiandentalacademy.com
35. Cylindrical Basket
The ITI implants are made from
CP titanium, have a titanium
plasma-sprayed surface and
promote increased bone contact
by increasing the surface area by
6 fold.
Were previously provided in
several designs – designated as
C,E,F,H and K.- to fit alveolar
ridges of varying ht. and width.
ITI hollow Cylinder
ITI 150 offset Hollow Cylinder
ITI hollow Screw
www.indiandentalacademy.com
36. Cylindrical Basket
Core-Vent basket design
combines a superior threaded
screw section with an inferior
hollow vented basket.
The self tapping threaded neck
provides initial stability to help
prevent micro movement during
healing.
Within the superior threaded
region there is a hexagonal-
threaded chamber that extends
downward towards the basket
area but does not communicate
with it.
www.indiandentalacademy.com
37. Cylindrical Basket
The Core-Vent implant is
manufactured in two
diameters: 3.5 and 4.5 mm
The threaded portion adds 0.8
to overall dimension, creating
outsides diameter of 4.3 and
5.3 respectively
Four length available are 16,
13, 10.5, and 8 mm
www.indiandentalacademy.com
38. Cylindrical Fin Finned or serrated root form
implants can offer advantages in
certain clinical situations.
These implants sometimes called
plateau implants have a series of
circumferential fins spaced along
the bone interfacing portion of the
implant.
They usually provides more
functional load bearing surface
area for efficient transmittal of
occlusal loads than other
implants.
Proper socket preparation should
result in light friction fit for
implant after insertion.

39. Titanium Plasma Sprayed Screw Implant
It consist of fine grain titanium particles applied to the
cylinder in an argon environment under extremely high
temp., pressure and velocity.
It offers an increase in surface area over the smooth
surface and, thus also more retention in the bone.
Some research has also shown that initial integration
into the host bone is somewhat accelerated through
that.
Available in diameter of 3.3 & 4 mm
and length of 8, 11, 13 & 15 mm.
www.indiandentalacademy.com
40. Titanium Screw Implant with a
Hydroxyapatite (HA) coating
Beyond an increase in surface area as
compared to smooth surface implants,
this surface has also shown to have an
accelerated initial integration, which
makes it ideal for quick initial post-
surgical stabilization in weak bone.
www.indiandentalacademy.com
41. Subperiosteal Implants :
Are implants, which
typically lie on top of the
jawbone, but underneath
your gum tissues. The
important distinction is
that they usually do not
penetrate into the
jawbone.
www.indiandentalacademy.com
42. Indications…
Some conditions that are contraindicated for root and blade form
may be indicated such as:
An unusual position of mental foramen
A dehiscence of mandibular canal
Generally atrophic mandible
A mutilated oral condition from extensive surgery
Severe gagging problems
Subperiosteal Implants :
www.indiandentalacademy.com
43. Transosseous Implants:
Are implants, which are
similar in definition to
Endosseous implants in that
they are surgically inserted
into the jawbone.
However, these implants
actually penetrate the entire
jaw so that they actually
emerge opposite the entry
site, usually at the bottom of
the chin.
Adv are immediate denture
placement and function

44. BLADE IMPLANTS
Linkow blade implants invented in 1967.
Long thin blade that will be surgically inserted into the groove in the bone .
Abutment projecting out from the blade to this crown or attachment for
denture can be placed.
It required the shared support of natural teeth also.
Restored within month so became most widely used in united states.
Linkow modified the design configuration for broad applicability in
maxilla & mandible, narrow ridges.

46. RAMUS FRAME IMPLANT developed Roberts & Roberts in 1970 .
The endosseous implant received stabilization from its anchorage
in ramus area bilaterally & in the symphyseal region.
It is now made of grade 2 CP titanium and used as posterior
support for a mandibular fixed partial denture when insufficient
height and width exist in body of the mandible.
The implant remain unloaded until proper osseous healing occurs.
These were used when insufficient bone(less than 6mm bone
height,and 3mm bone width)is present in body of mandible to
support an endosteal implant.
These are one piece blade implants which take support from bone
in ramus region

48. ITI BONE FIT IMPLANT SYSTEM
Developed by ‘International Team for Implantology’.
Three different types
Single stage & two stage.
Transgingivally placed in healing phase so second surgical procedure
for uncovering the implant is avoided.

Branemark.
The long fixture can be anchored in zygoma by approaching through the
sinus .
Severely resorbed maxilla.

51. 1.crest module:- the
crest module of an implant is that
portion designed to retain the
prosthetic component.
It represents the transition zone
from implant body design to
transosteal region of the implant
at the crest of the ridge.
IN THE IMPALNT BODY:-

52. Antirotational features
External hex
o Most widely available
o Found on top of abutments
o Hexagonal geometry
Internal hex
o Provides more precise implant
abutment interface
o Disadvantage – screw loosening
o Seats the abutment into hexagonal
depression

63. SPLINE ATTACHMENT
Splines are fin to groove anti rotational design
Consist of six external components called tines which
protrude 1mm from implant and are matched to a
female embedded in a abutment base
www.indiandentalacademy.com
64. Implant collar:-
Designs that incorporate a microscopic component into the
implant bodies by coatings with hydroxyapatite, at the superior
aspect of the crest module.
The collar allows functional remodeling to occur to a more
consistent region on implant.
It suggests that crestal modeling is limited to the smooth region
of the implant.
Its designs varies from straight to flared neck, beveled, reverse
beveled, tapered, smooth surfaced or micro threaded.

65. COVER SCREW:-
At the time of insertion of the
implant body or stage 1
surgery, a first stage cover is
placed into the top of implant
to prevent bone, soft tissue,
or debris from invading the
abutment connection area
during healing.
www.indiandentalacademy.com
66.
HEALING
SCREW:-
After a prescribed healing
period sufficient to allow a
supporting interface to
develop, the second stage
may be performed to expose
the implant andor attach a
transepithelial portion.
This transepithelial portion is
termed a permucosal
extension because it extends
the implant above the soft
tissue and results in
development of permucosal
seal around the implant
www.indiandentalacademy.com
67. Abutment :- is the portion of the implant that supports andor
retains a prosthesis or implant super structure.
Three categories of implant abutments are available.
1.screw retained
2.cement retained
3.abutment for attachment uses an attachment device to
retain a removable prosthesis.
HYGIENE COVER SCREW:-place over the abutment to prevent
debris and calculus from invading the internal portion of abutment
during prosthesis fabrication.

68. TRANSFER COPING:-transfer
coping is used to position an
analog in an impression and
defined by the portion of
implant it transfers to the
master cast, either the implant
body transfer coping or the
abutment transfer coping.
Direct transfer coping
Indirect transfer coping
www.indiandentalacademy.com
69. IMPLANT ANALOG:-used in
the fabrication of the
master cast to replicate
the retentive portion of the
implant body or abutment.
After the master
impression is obtained, the
corresponding analog is
attached to the transfer
coping and assembly
poured in the die stone
