Prospective, 1-year observational study of double-threaded tapered body dental implants with immediate loading.

STATEMENT OF PROBLEM Unlike conventional loading protocols, the immediate loading of single implants has not been fully investigated. PURPOSE The purpose of this study was to assess the prosthetic and esthetic periimplant mucosal outcomes of immediately restored dental implants during a 1-year follow-up. MATERIAL AND METHODS Twenty participants meeting the established inclusion criteria received double-threaded, tapered body dental implants (SuperLine; Dentium). Implants were placed and stabilized at a minimum of 35 Ncm of torque and restored immediately after the surgery with interim restorations. These were replaced with definitive restorations 6 months after implant placement. Clinical measurements at each visit included resonance frequency analysis, the evaluation of the participants' oral health (gingival and plaque indices), and the esthetic outcome of the interim or definitive restoration. RESULTS Implants placed in this clinical study had a 100% success rate. The oral health and esthetic outcomes were favorable for all participants. CONCLUSIONS Double-threaded, tapered body dental implants that were placed and immediately restored with fixed interim prostheses and with definitive prostheses after 6 months remained stable and functional after 1 year.
