Abstract

Abstract: Objective: To compare the short-term clinical outcomesof immediate implantationversus delayed implantationin preserved sockets of the maxillary molar areaafter systematic periodontaltreatment in patients with severe chronic periodontitis. Methods: Thirtypatients with severe chronic periodontitis and partially edentulous in the maxillary molar area were screened outfrom January 2013 to 2015 in the Department of Periodontology,Stomatologic Hospital & College, Anhui Medical University. After the control of periodontal infection, a total of 49 implants were implanted, including 23 immediate implantations and 26 delayed implantations. Implant supported dentures were made after 3-6 months. All patients were followed up for 6 months after loading. The implant failure and peri-implant tissue conditions were recorded. Results: Two implants failed in the immediate implantation group and one implant failed in the delayed implantation group. The survival rate was 91.30% and 96.15%, respectively. At the delivery of definitive crowns and 6 months after loading, all implants received periodontal examination and there was no statistically significant difference, including probe depth (PD), blooding index (BI), and blooding of probe (BOP). During the observation time, the definitive crowns and periodontal tissue of all successful implants were in good function. Conclusion: After comprehensive periodontal treatment andwell-control,the clinical outcome appears to be similar for immediate implantation and delayed implantation in the maxillary molar area for patients with severe chronicperiodontitis.
