3 History of dental implants

4 Three major groups of dental implants Subperiosteal On Bone Transosteal Through Bone Endosteal In Bone

5 Subperiosteal Implants -Designed primarily to anchor dentures in the completely edentulous patient. -These implants consist of a metal framework that attaches on top of the jawbone but underneath the gum tissue

6 Fabrication

7 Subperiosteal Implants Epithelial migration, development of extended peri-implant pockets, and chronic infections led to exposure of the implant framework and its eventual removal.

9 Transosteal (staple) Implants Designed primarily to anchor dentures in the completely edentulous patient These implants are either a metal pin or a U-shaped frame that passes through the jawbone and the gum tissue, into the mouth Titanium

experiments concerned with wound healing.

15 Osseointegration Discovered by P. I. Branemark in the 1960 s while he was conducting a series of animal experiments concerned with wound healing. In these experiments he used an optical chamber made of titanium. When he attempted to remove the chamber from its bone site he noticed that the bone adhered to the titanium chamber with great tenacity Bone * Chamber * * *Courtesy P.I.

16 Osseointegration Direct structural and functional connection between live bone and the surface of an implant under load P.I. Brånemark, MD, PhD Center for Applied Biotechnology Götenburg, Sweden

17 -He recognized the importance of this phenomenon -Over 50 designs were tested. He and his colleagues finally settled on a simple screw shape with a hex on the top. Osseointegration

18 Titanium Ninth most abundant element on earth Easy to divide into useful shapes which maintain their strength Strong

19 Titanium Resistant to corrosion Light weight

20 Endosseous Implants

21 Designs Blades Cylinder Screw Mini implants

22 Designs Zirconium Implant

23 TiOblast

24 Benefits of Dental Implants Function Stability Improved nutrition Taste Preserves bone Improved appearance Preserves teeth Renewed selfconfidence

25 Osseointegration 6-8 weeks mandible months - maxilla

26 Quality Type I, II, III, IV

27 Type I Type I bone is comparable to oak wood, which is very hard and dense

28 Type II Type II bone is comparable to pine wood, which isn't as hard as type I.

29 Type III Type III bone is like balsa wood, which isn't as dense as type II

30 Type IV Type IV bone is comparable to styrofoam
