CLINICAL Immediate Restoration of NobelActive Implants Placed Into Fresh Extraction Sites in the Anterior Maxilla Christopher Bell Robert E. Bell, DDS* The aim of this study is to compare the success rates of immediately placed and loaded NobelActive implants with the success rate of immediately placed implants that were allowed to osseointigrate prior to loading. The charts of all patients in a private oral surgery office receiving single-unit dental implants in the maxillary anterior region in fresh extraction sites from 2008-2011 were evaluated. All patients receiving NobelActive implants and immediate restorations were included in the study group, while those receiving implants with delayed restorations were included in the control group. Patient records were evaluated for variables such as age, gender, torque values at time of implant placement, smoking habits, use of bisphosphonates, and other significant diseases such as diabetes. The success rate of the study group was 92.9%, whereas the success rate of the control group was 97.6%. This was not statistically significant. Torque values of the failed implants of the study group were similar to those of successful implants in the study group. All implants placed in patients scheduled for immediate loading achieved high torque values and were able to be restored immediately. NobelActive implants were able to obtain high torque values for predictable immediate restoration in fresh extraction sites. Acceptable success rates with excellent soft tissue healing were achieved.

Implant design and surface technology has also changed. Roughened surfaces, altered thread patterns, and internal connectors have improved implant success and decreased healing times. Implants placed immediately into fresh extraction sites have been shown to be successful. Immediately loaded implants-whether they be splinted and in occlusion or single units immediately restored out of occlusion in healed sites-have high success rates with proper patient selection.1 Studies of immediately restored implants placed in fresh extraction sites have sometimes met with higher failure rates.2,3 This is reasonable because of Central Valley Dental Implant, Tulare, Calif. * Corresponding author: e-mail: tularebell@gmail.com DOI: 10.1563/AAID-JOI-D-11-00254 the decreased buttressing of an extraction site compared to a healed site. Other studies of immediately placed restored implants have demonstrated high success rates.4-6 Immediate restoration of implants placed into fresh extraction sites, if successful, has several advantages including: simultaneous soft and hard tissue healing, support of the soft tissue by the temporary restoration, and patient convenience. Chaushu2 compared immediately loaded singletooth implants placed in fresh extraction sites to immediately loaded implants in healed sites. The implants in extraction sites had an 82% success rate compared to 100% success in healed sites. Aly3 noted a similar success rate of 85% for immediately restored single-unit implants in fresh extraction sites. Mijiritsky,7 however, found a 95.8% success rate for implants placed in fresh extraction sites immediately restored and out of occlusion. Studies by Cornelini8 and by Crespi9 found immediately placed and restored implants had a 100% integraJournal of Oral Implantology 455
