Immediate provisionalization of single-tooth implants placed in fresh extracted sites of esthetic zones: Up to 4 years of follow-up

Background: Immediate single-tooth implant has become an increasingly common and successful treatment. Single-tooth rehabilitation patients can be predictably treated with a favorable esthetic outcome using immediate provisionalization. Use of removable prosthesis soon after the extraction of anterior tooth has been replaced by single-tooth implants with immediate provisionalization. The goal of this study is to evaluate the long-term survival rate of single-tooth implants in fresh extracted sites at the maxillary and mandibular anterior region, followed by immediate provisionalization. Materials and Methods: A total of 42 implants were placed in 29 patients. Immediate provisionalization restorations were placed. Occlusal contacts were avoided. Follow-up started from the day of implantation, and ranged from 24 to 48 months, with an average of 36 months. Results: Two implants failed 1 month after placement due to bone loss and overloading, leading to peri-implantitis. Overall survival rate was 95%. The mean marginal bone loss was 1.5±2 mm. Conclusion: The greatest benefit from this procedure is patient's satisfaction. Immediate provisionalization of single-tooth implants at fresh extracted sites is effective, when minimal provisionalization criteria are met.
