Why is titanium considered unique for dental implants?
It is resistant to corrosion and release of metallic ions.
What happens when cobalt-chrome alloys are subject to corrosion?
Release of metallic ions into adjacent tissues.
Which element is needed to be extracted from mineral ores such as ruFle and ilmenite?
Titanium

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.
