The use of implants in the clinical practice has significantly increased nowadays and the available therapeutic options are also numerous. The patients' expectations concerning the final functional and esthetic result are higher than in the previous years. Dental implants have been used for the restoration of partially and completely edentulous for decades with high success rates. According to the classical treatment protocol, as introduced by Branemark, the implants should remain unloaded for a period of 3-6 months. In some cases however the fabrication of long-term implant-supported provisional restorations is preferable or needed. The reasons advocating the use of implant-supported provisional restorations may be the guided tissue formation around the implants to achieve a favorable emergence profile, the modification of the treatment plan with additional implants or the delay due to increased osseointegration periodof the opposing arch. Implant-supported interim restorations can improve the speaking and chewing ability of the patients and their aesthetic appearance as well. They can also prohibit movement of the adjacent teeth and eruption of the antagonists. A lot of valuable information can be obtained from the provisional restoration, thus facilitating the fabrication of the final prosthesis. From the aesthetic point of view the size, position and shape of the teeth can be evaluated. The emergence profile and the soft tissue support may result to a predictable final result. As far as the functional ability is concerned, the patient's adaptation is tried over a period of time and the occlusal scheme is put under clinical trial before the definitive restoration. The fabrication of provisional restorations in single tooth implants is a relatively simple clinical procedure requiring attention in specific clinical steps. In cases of partially or completely edentulous patients, the clinical complexity is increased due to the extension of the restoration. In this paper the indications of implant-supported provisional restorations are analyzed and the clinical steps are presented in two clinical cases.
