Dental Implants have changed the face of dentistry over the last 25 years. What are dental implants? What is the history of dental implants? And how are they used to replace missing teeth? This section will give you an overview of the topic of dental implants, to be followed by more detail in additional sections.
As with most treatment procedures in dentistry today, dental implants not only involve scientific discovery, research and understanding, but also application in clinical practice. The practice of implant dentistry requires expertise in planning, surgery and tooth restoration; it is as much about art and experience as it is about science. This site will help provide you with the knowledge you need to make informed choices in consultation with your dental health professionals.
Dental Implants
Dental illustration by Dear Doctor
Let’s start from the beginning: A dental implant is actually a replacement for the root or roots of a tooth. Like tooth roots, dental implants are secured in the jawbone and are not visible once surgically placed. They are used to secure crowns (the parts of teeth seen in the mouth), bridgework or dentures by a variety of means. They are made of titanium, which is lightweight, strong and biocompatible, which means that it is not rejected by the body. Titanium and titanium alloys are the most widely used metals in both dental and other bone implants, such as orthopedic joint replacements. Dental implants have the highest success rate of any implanted surgical device.
Titanium’s special property of fusing to bone, called osseointegration (“osseo” – bone; “integration” – fusion or joining with), is the biological basis of dental implant success. That’s because when teeth are lost, the bone that supported those teeth is lost too. Placing dental implants stabilizes bone, preventing its loss. Along with replacing lost teeth, implants help maintain the jawbone’s shape and density. This means they also support the facial skeleton and, indirectly, the soft tissue structures — gum tissues, cheeks and lips. Dental implants help you eat, chew, smile, talk and look completely natural. This functionality imparts social, psychological and physical well-being.

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

Vertical ridge augmentation is sometimes required for dental implant placement. The presentation looks at various conventional and newer techniques for ridge augmentation in the oral cavity.
Fixed partial dentures transmit forces through the abutments to the periodontium. Failures are due to poor engineering, the use of improper materials, inadequate tooth preparation, and faulty fabrication. Of particular concern to prosthodontist is the selection of teeth for abutments. They must recognize the forces developed by the oral mechanism, and resistance.
Successful selection of abutments for fixed partial dentures requires sensitive diagnostic ability. Thorough knowledge of anatomy, ceramics, the chemistry and physics of dental materials, metallurgy, Periodontics, phonetics, physiology, radiology and the mechanics of oral function is fundamental.
11. • Bone needs stimulation to maintain its form and
density.
• Loss of teeth leads to loss of width then height of the
bone.
• After one year 25% of width and up to 4 mm of
height will be lost.
TODAY THE PROFESSION MUST CONSIDER NOT ONLY
THE LOSS OF TEETH BUT ALSO THE LOSS OF BONE.
12. • It Maintains Bone Volume.
• Preservation Of Adjacent teeth.
• Natural Emergence Profile.
• Increases stability and Retention.
• Reduce Removable prosthesis size.
13. What is a dental implant ?
• A dental implant is an artificial tooth root
replacement and is used in prosthetic
dentistry to support restorations that
resemble a tooth or group of teeth.
29. Osseointegration
Osseointegration is defined as “a
direct structural and functional
connection between the ordered
living bone and the surface of the
load carrying implant”
(Branemark, 1983).
Bone has been shown to be
approximately 20 nm away from
the implant surface when
examined with the electron
microscope (Albrektsson, 1985).
31. The Edentulous Alveolar Ridge
• The formation and the continued preservation
of alveolar ridge is dependant on the
continued presence of teeth.
• Also the shape of teeth is an important factor
in determining the shape of the alveolar
process.
32. Thick tissue biotype subjects have
short and wide teeth
Thin tissue biotype subjects have
long and narrow teeth
34. Bone loss is more pronounced on the buccal aspect than the
lingual/palatal aspect of the ridge
35. CLASSIFICATION OF REMAINING BONE
A& B Substantial amount of alveolar bone remains
C, D & E Minute amount of alveolar process remains
Lekhom and Zarb (1985)
40. MACRO DESIGN
IMPLANT MATERIALS
Commercially Pure Ti Ti Alloy Zirconia
Titanium 6AL-4V
41. • Titanium implants are biocompatible due to the formation of
an oxide layer on their surface which is resistant to corrosion
and have hydrophilic properties (Hansson et al 1983), When
exposed to air, Titanium forms an oxide layer immediately that
reaches a thickness of 2 to 10 nm by 1 sec and provides
corrosion resistance (Ducheyne 1988; Donley and Gillette
1991).
• Because of the high passivity, controlled thickness, rapid
formation, ability to repair itself instantaneously if damaged,
resistance to chemical attack, catalytic activity for a number of
chemical reactions and modulus of elasticity compatible with
that of bone of titanium oxide, Titanium is the material of
choice for intraosseous applications (Parr et al 1985; Kasemo
and Lausmaa 1985).
46. • The original endosseous implants were
cylindrical (parallel) in design, although this
design was proven to be successful, it was not
suitable for all applications. One of the most
obvious limitations of its use is narrow ridges
and ridges with concavities as there is an
increased risk of perforation in the labial bone
(Garber et al 2001).
47. • The introduction of tapered implants resulted
in improved esthetics and easier placement
between the adjacent natural teeth as it
resembles more closely the shape and taper
of the original teeth roots (Shapoff 2002) ,
also it has the ability to accommodate the
shape of thin ridges and ridges with labial
concavities more than cylindrical implants
(Garber et al 2001).
48. • The theory behind the use of tapered implants
is to provide for a degree of compression of
the cortical bone in a poor implant site,
tapered implants distribute forces into the
surrounding bone, thereby creating a more
uniform compaction of bone in adjacent
osteotomy walls compared with parallel
walled implants. Thus when inserted, it
creates lateral compression of bone
(O’sullivan et al 2004).
57. Implants Threads
• Threads are added to the implant body and
are used to:
1. maximize initial contact between the
implant and bone
2. To improve initial stability
3. To enlarge implant surface area
4. To favor dissipation of interfacial stress.
62. • The original studies on osseointegration were
performed using turned (machined) surface
implants. Efforts to enhance implant surface
technology have focused on improving the
predictability, rate, and degree of
osseointegration.
• Until now, there is no consensus concerning
the most appropriate implant surface
topography (Raghavendra et al 2005).
63. • Some important advantages have been
attributed to increased surface roughness.
These include increased surface area of the
implant adjacent to bone, improved cell
attachment to the implant surface, increased
bone present at the implant surface, and
increased biomechanical interaction of the
implant with bone (Cooper 2000).
66. •Edentulous ridge (Branemark 1952) 60 years of
research
•Single tooth replacement 41 years of research
•Immediate tooth replacement 34 years of research

•Included in treatment
•Extraction and site

•Can be joined to
implants
•Independent implant restoration.
• If adjacent to an edentulous site consider reducing
the prognosis
70. EXAMPLES
•Smokers moderate and sever Periodontitis extraction and
dental implant placement (implant is in direct contact with bone
less effect from smoking)
•Unsuccessful treatment with progressive bone loss When
remaining bone is 10 mm extraction (minimum predictable
implant length 10 mm).
•Grade III Furcation involvement Implants is more predictable
than root amputation and hemi sectioning.
•Mobility mobile teeth are poor in terms of load carrying and
should be removed.
