The screw-shaped root system can be of various lengths and different diameters in order to use the greatest amount of bone available.
The material used for implants today and accepted by the international scientific community is titanium, a biomaterial.
The biomaterials used in medicine that interact with the biological system (bone) are classified as biotolerable, bioinert, bioactive.
biotolerable : show fibrous tissue between implant and bone
bioinert : are bone-implant contact (eg titanium)
Bioactive : are chemical and physical connection between bone and implant
for the use of a biomaterial implant requires two conditions: biocompatibility and mechanical properties
Titanium offers both a good biocompatibility, bioinerte as both an excellent resistance to load and corrosion.
70-80 years scientific studies have made us understand the intimate relationship between bone and implant and was coined the term osseointegration, which means that direct contact between bone and titanium receiver.
The implant surface was studied in the 90s and researchers have tried to respond to the needs of better integration between bone tissue and implant surfaces.
The result was that the titanium implants with rough surface, especially processed and prepared, met with more success than those in titanium with smooth surface, more especially in the bone "tender" or of inferior quality.
All this knowledge allow us to say that dental implants can be applied in the absence of "rejection", as there is no adverse immune reaction, and with great predictability, with successful surgical close to 100% due to new surfaces.
