A multicenter prospective clinical trial on the effect of domestic bone level implants on single tooth implantation and restoration
J Objective To evaluate the clinical application effects of a domestic bone-level implant system for restoring single tooth loss,and provide clinical evidence for the promotion and application of domestic implants.Methods A prospective,multicenter clinical trial was conducted from April 2018 to January 2020 in three institutions:Department of Oral Implantology,School &Hospital of Stomatology,Wuhan University,Department of Stomatology,The First Affiliated Hospital of Zhejiang University School of Medicine,and Department of Stomatology,The Third Hospital of Hebei Medical University.The trial planned to include 100 patients for single tooth implantation and restoration,followed up for 1 year,to evaluate the implantation success rate and other related outcomes.Results This study screened a total of 142 patients and ultimately included 100,comprising 43 males and 57 females with age of(47.0±12.2)years.Ninety-eight out of 100 patients completed a one-year follow-up(98.0％),while 2 patients terminated the trial early due to implant loosening(2.0％).After a one-year follow-up,the implants of the 98 patients were all functioning successfully,with a success rate of 98.0％(98/100).The patients were satisfied with the overall restoration effect.Conclusions This study indicates that the domestic bone-level implant system has achieved favorable short-term clinical outcomes for single-tooth implantation and restoration.
