ITI Implant System The ITI system was created in the early 1970s by the Department of Conservation Dentistry at the University of Bonn, Switzerland, and the privately owned Straumann Institute in Waldenbau, Switzerland. Since 1974, the system has been successfully used and a large amount of clinical documentation has been accumulated. ITI can be said to be a representative of the non-physical implant type two-stage implant system, which is exposed to the oral cavity and heals in a non-covered state after one-stage surgery. No second-stage surgery is required, and the abutment can be directly attached to the abutment to complete the repair after the osseointegration is completed. Machined grade 4 titanium. Made of commercially pure titanium (grade 4 ISO5832/1). Oxygen and iron are increased compared to ~3 grade titanium. Its mechanical properties are improved. Increased bone contact area due to the presence of titanium plasma coating (TPS). The surface of all ITI implants has a titanium slurry plasma coating with microscopic pores, the surface roughness of the engraved coating is 20m, and the thickness is about 20-30m. The coating increases the surface area and the percentage of osseointegration, and significantly increases its resistance to dislocation. Smooth machined neck. The transgingival neck of ITI is cup-shaped and has a smooth machined surface, which the designer believes is beneficial for the attachment of the soft tissue of the neck and the prevention of infection of the periodontal soft tissue. Precise and standardized preparation of the implant position achieves initial stability. After application, we also realized that the precise design of the system for bone preparation can achieve better initial stability. Easier and more reliable than other implant systems.
