Objective:aim of this study was the evaluation of immediately loaded implants in a series of different anatomical configurations. Methods: two hundred eighty three patients participated in this study. A total of 1036 implants were placed, 51 IMZ Twin Plus (Friadent, Mannheim, Germany), 188 Frialit-2 (Friadent, Mannheim, Germany), 212 XiVE (Friadent, Mannheim, Germany), 52 Frialoc (Friadent, Mannheim, Germany), 136 Branemark (Nobel Biocare, Goteborg, Sweden), 108 Restore (Lifecore Biomedical, Chaska, Minnesota, USA), 266 Maestro (Biohorizons, Birmingham, Alabama, USA), and 23 other types of implants. The treatment included 58 completely edentulous mandibles, 33 completely edentulous maxillae, 26 edentulous anterior mandibles, 34 edentulous posterior mandibles, 23 edentulous anterior maxillae, 25 edentulous posterior maxillae, and 84 single restorations. Six hundred eighty three implants in 106 patients were occlusally loaded, while 353 implants in 177 patients underwent non functional loading ( immediate restoration without occlusal contact). The follow-up varied from 6 to 72 months. Six implants out of 683 occlusally loaded implants failed with a percentage of implant survival of 99.1%; 2 implants had been inserted in completely edentulous maxillae, 2 implants in posterior mandibles and 2 implants in anterior maxillae. Moreover, 4 of these failed implants had been inserted in post-extraction sites. Results: five out of 353 immediately non functionally loaded implants failed with a percentage of implant survival of 98.6 %; all these failures had occurred in single teeth replacements and in four cases the affected tooth was the central superior incisor. Most failures were observed in the first year of loading. All the other implants were osseointegrated from a clinical point of view, and have been functioning satisfactorily. Conclusions: our results show that very high implant success percentages con be obtained with the immediate loading of dental implants.
