Purpose: Marginal bone loss (MBL) around dental implants adversely affects long-term implant treatment outcomes. The purpose of this study was to investigate the risk factors of MBL in tissuelevel implants. Materials and Methods: The study included 42 patients with 69 tissue-level implants placed between May 2015 and January 2020 at the Department of Periodontology of Dankook University Dental Hospital. Patient and implant data were collected from medical records and panoramic and periapical radiographs. MBL was measured as the distance from the apex of the implant fixture to the most coronal point where the implant and bone meet, and calibration was performed using the actual length of the implant. Student’s t -test was used to compare the groups by age (< 60 or ≥ 60 years), sex (male or female), hypertension status, diabetes status, implant diameter (< 5.0 or 5.0 mm), implant length (7.0 or ≥ 8.5 mm), position of implants (maxilla or mandible), collar height (≤ 2.0 or 2.8 mm), splinted implant prosthesis, and bone grafting on MBL. One-way ANOVA was used to compare the MBL of the three groups by implant insertion depth less than 0.5 mm, between 0.5 to 1.0 mm, and more than 1.0 mm. The chi-square test for linear trend was used to determine whether the implant insertion depth affected the thread exposure. Results: There was no statistically significant difference between the groups in terms of sex, age, hypertension, diabetes, diameter, length, location, collar height, splinted implant prosthesis, and bone grafting. One-way ANOVA showed that the MBL was significantly higher in the group with implant insertion depth ≥ 1.0 mm than in the other groups. However, the frequency of thread exposure decreased as the implant insertion depth increased. Conclusion: There were no statistically significant factors associated with MBL, except for implant insertion depth. As the implant insertion depth increased, the amount of MBL increased, but the frequency of thread exposure decreased.
