CLINICAL Immediate Loading of Single Post-Extractive Implants in the Anterior Maxilla: 12-Month Results From a Multicenter Clinical Study Tommaso Grandi, DDS1* Giovanna Garuti, DDS1 Rawad Samarani, DDS2 Paolo Guazzi, DDS3 Andrea Forabosco, MD1 The purpose of the study was to evaluate survival and peri-implant bone levels of single, immediately loaded post-extractive implants in the anterior maxilla 12 months after implant placement. Thirty-six consecutive patients from 3 study centers were included in the study. The concerned sites were upper premolars, canines, and incisors. For each patient the following data were recorded: reason for tooth extraction, bone quality, implant size, and final insertion torque. Implants were placed using a flapless technique and immediately loaded with a nonoccluding temporary restoration. Final restorations were provided 4 months later. Peri-implant bone resorption was evaluated radiographically after 6 and 12 months. The average final insertion torque was 70.55 Ncm. One implant inserted in D3 quality bone with a 35-Ncm seating torque was lost. All other implants had a final insertion torque ranging between 50 and 80 Ncm. The average peri-implant bone loss was 0.437 and 0.507 mm at 6 and 12 months, respectively. All the sites maintained excellent papillae and peri-implant soft-tissue conditions. The resulting 1-year success rate was 97.2%. Immediate nonfunctional loading of single postextractive implants in the anterior maxilla is a predictable treatment. And it seems that achieving high insertion torques by placing self-tapping/self-condensing implants in an underprepared osteotomy is favorable. Key Words: immediate loading, single post-extractive implants, anterior maxilla, survival rate, bone resorption, insertion torque INTRODUCTION I 1 n the past two decades some of the original prerequisites for successful osseointegration are being redefined to meet patients’ demands to reduce treatment time and increase comfort. Immediate loading and immediate implantation concepts have been proposed to shorten treatment time and to allow the patient to quickly recover function and esthetics.1 Department of Integrated Activities of Specialized Head-Neck Surgery, University of Modena and Reggio Emilia, Italy. 2 Saint-Joseph University, Beirut, Lebanon. 3 Private practice, Modena, Italy. * Corresponding author, e-mail: tommaso.grandi@unimore.it DOI: 10.1563/AAID-JOI-D-11-00058 Immediate loading is gaining popularity among clinicians, and the outcome of immediately loaded dental implants is being investigated more and more in clinical trials and animal studies.2–4 Even though the results are sometimes conflicting, there is an increasing corpus of evidence to support the application of immediate loading.1 However, most of the clinical studies on immediate loading have been performed in the totally edentulous maxilla and mandible. Few studies have investigated immediate loading of implants for single tooth replacement,5,6 and fewer still have examined immediate loading of implants placed in fresh extraction sockets.7,8 The current state of knowledge suggests that Journal of Oral Implantology 477
