2. INTRODUCTION
•Definition of dental implant
“Dental implant is an alloplastic and biocompatible material
placed into (endosseous) or onto (subperiosteal) the jawbone
to support a fixed prosthesis, or to stabilize removable
prosthesis.”
...Clinial implantology (AVS)

3. History of dental implant
• Modern implants had their origin in the discovery by a Swedish professor of
Orthopaedics named Branemark, who found that titanium (a very strong and
noncorrosive metal) attached itself to a bone when it was implanted into it.
During one of his experiments, he embedded titanium devices into rabbit’s leg
bones to study bone healing. After a few months, he tried to remove these
expensive devices and when he could not, he noticed that the bone had attached
itself to the metal. He eventually decided that the mouth was far more practical
than the leg for his experiments, as it was easier to watch the progress and there
were more toothless people than people with serious joint problems. He called
the attachment of the titanium to the bone ‘osseointegration’ and in 1965 he
used the first titanium dental implant in a human volunteer.

5. History of dental implant
• Over the next few years, he published a lot of research
on the use of titanium dental implants, and in 1978 he
commercialized the development and marketing of his
titanium dental implants. Over 7 million implants under
his brand name have been placed. Needless to say, there
are other dental implant companies that have used his
patent.

6. Prosthetic options
In 1989, Misch proposed five prosthetic options for implant
dentistry .

7. FP-1Fixed prosthesis
• replaces only the crown; looks like a natural
tooth

8. FP-2Fixed prosthesis
• replaces the crown and a portion of the root;
crown contour appears normal in the occlusal half
but is elongated or hypercontoured in the gingival
half

9. FP-3Fixed prosthesis
• replaces missing crowns and gingival color and
portion of the edentulous site; prosthesis most
often uses denture teeth and acrylic gingiva, but
may be porcelain to metal

10. RP-4Removable prosthesis
• overdenture supported completely by
implant

11. RP-5Removable prosthesis
• overdenture supported by both soft tissue and
implant

12. 1. Psychological satisfaction of having fixed teeth.
2. More chewing efficiency.
3. Long lasting.
4. Preserves alveolar bone loss.
Advantages of full-arch fixed prosthesis

13. 1. Expensive, because of the need for more implants.
2. Often needs expensive and more invasive bone aug- mentation
procedures.
3. More technique-sensitive.
4. More specific implant placement needed.
5. Difficult to maintain.
6. Difficult to repair.
7. More and continuous forces on the implants can- not be avoided in
patients with parafunctional forces (bruxism).
8. Less support to the perioral muscles when compared to
overdentures.
Disadvantages of full-arch fixed prosthesis
