Although dental medicine has advanced greatly in recent decades, edentulousness remains a problem in a large number of patients, especially in less developed countries. Standard dimension implants are successfully used in the restoration of missing teeth, regardless of whether it is the replacement of teeth in total edentulousness, or the replacement of teeth in shortened and interrupted dental arches. However, it is not always possible to install implants of standard dimensions in the jaw, they require a certain volume of bone, which is often not the case with extremely resorbed alveolar ridges. Mini dental implants are narrow one-piece implants less than 3 mm in diameter, their development occurred out of the need for immediate loading and immediate prosthetic rehabilitation. A complete denture retained on mini dental implants is a fast, cheap and effective solution for complete edentulousness. The pioneer and inventor of the mini dental implants is considered to be the American dentist and implantologist Dr. Victor Irvine Sendax, who together with his associates Dr. Anthony Ricciardi and Dr. Burton Blakin developed implantation protocols and retention concepts for mini dental implants. The advantage of mini dental implants is the possibility of their installation in extremely resorbed alveolar ridges in the bucolingual direction due to their small width. Another advantage of mini dental implants is minimal invasiveness during the implant placement. It is not necessary to lift the mucoperiosteal flap for the installation of mini dental implants, and the bed is prepared only in the cortical bone. They are also lower priced than standard size implants, allowing them to be used in a wider population. Interest in the installation of mini dental implants will certainly increase in the future, due to their many advantages as well as due to the increased interest in implantology among dentists in general.
