## Indications for use
Straumann® dental implants are suitable for the treatment of oral endosteal implantation in the upper and lower jaw and for the functional and esthetic oral rehabilitation of edentulous and partially dentate patients (unless specific indications and limitations are present, as stated below). Straumann®)dental implants can also be used for immediate or early implantation following extraction or loss of natural teeth. Implants can be placed with immediate function on single-tooth and/or multiple tooth applications when good primary stability is achieved and with appropriate occlusal loading, to restore chewing function. The prosthetic restorations used are single crowns, bridges and partial or full dentures, which are connected to the implants by the corresponding elements (abutments). When placing implants in the posterior region, we recommend using only large diameter implants. In cases of fully edentulous patients, 4 or more implants must be used in immediately loaded cases. Specific indications for small diameter (0 3.3 mm) implants: Because of their reduced mechanical stability, small diameter implants are only used in cases with a low mechanical load. Placement in the molar region is not recommended. Abutments are intended to be placed into dental implants to provide support for prosthetic reconstructions such as crowns, bridges and overdentures. The Straumann NNC Temporary Abutments are indicated for use in Straumann NNC Tissue Level Implants for temporary restorations of single crowns and bridges for up to six months. Straumann NNC Healing Caps and NNC Closure Screws are intended for use with the Straumann NNC Tissue Level Implant system to protect the inner configuration of the implant. Healing Caps have a secondary function to maintain, stabilize and form the soft tissue during the healing process.
