Study Notes
Osseointegration
- Per-Ingvar Branemark called the process of direct contact between bone and metallic implants "osseointegration".
- In the context of osseointegration, "direct contact" refers to the formation of a strong bond between the bone and the implant surface, without the presence of intervening soft tissue.
Dental Implants
- Titanium is used to manufacture the screw in dental implants due to its unique properties.
- The surface of the screw is called "machined" when it is left in its original state.
- Titanium is considered unique for dental implants because of its biocompatibility, corrosion resistance, and strength.
History of Implantology
- The first person to receive a dental implant was Gösta Larsson, who contributed to the invention of modern day implantology.
- Gosta Larsson's initial set of implants served as a prototype for oral prostheses.
Metallic Implants
- Cobalt-chrome alloys are subject to corrosion, which can lead to the release of metallic ions.
- The presence of metallic ions from cobalt-chrome alloys can cause an inflammatory response.
Titanium Production
- Titanium is extracted from mineral ores such as rutile and ilmenite.
