Evaluation of implant survival in grafted and ungrafted bone: a 5-year follow-up study

Abstract

Introduction: This study aimed to evaluate the success rates of dental implants placed in native bone to those placed in grafted bone. Materials and Methods: A retrospective evaluation of patients who underwent dental implant procedures between 2016 and 2018 and who had a 5-year follow-up. These data included the patient's demographic information, the number and regions of implants, failed implants, grafting type, technique and healing time. Two groups were used: Group 1, the study group, consists of implants made in the grafted bone, and Group 2, the control group, consists of implants made in the ungrafted bone. Results: The placement of 3170 implants was in 890 patients. The findings indicate that a majority of the implants, specifically 88% (n=2791), were not subjected to grafting procedures. However, the survival rate of the implants was 98.8%. The rate of implant survival was higher in the ungrafted bone compared to the grafted bone (p=0.039; p
