Background: The implant-prosthetic restoration in single missing tooth is a viable treatment option for the functional rehabilitation of tooth loss. Several published studies show that the deadline and the type of functional loading of the implant for single missing teeth is not decisive for the survival and success rate of the implant. Although the conventional protocol is still the "gold standard", the immediate loading of dental implants in the fresh post-extraction socket of the aesthetic area has an excellent prognosis. Immediate functional loading is successfully adopted to minimize the treatment time with immediate and impact benefit on the patient's quality of life and satisfaction. The aesthetic result is not yet systematically included in the success criteria of the therapy through implant, although a trend for this is more common in recent publications, particularly in publications evaluating the implant prosthetic rehabilitation in the anterior maxilla and mandible. In order to obtain optimal aesthetic results, it is necessary to take into account the other aesthetic parameters, together with the chosen material for the fabrication of the implant-supported single crown and the type of prosthetic abutment.
Conclusions: The systematic review of the contemporary specialty literature examines the types of implantations and implant-supported restorations for single tooth replacement, the survival rates of the implant, the survival of the crown on the implant and the successful implant, incidence of biological, technical and aesthetical complications of the implants and prosthetic restorations on implants, the quality of life related to the oral health to patients with implant-prosthetic treatment.
