Objective The aim of this study was to assess changes in marginal bone level around immediately loaded single implant used to retain mandibular overdenture with two different types of attachment (bollard coping and locator). Patients and methods Twenty completely edentulous patients were randomly selected from the Outpatient Clinic, Department of Removable Prosthodontics, Faculty of Dental Medicine, Al-Azhar University (Boys, Cairo). Patients were divided into two groups: Group I received single implant retained overdenture with a new design (bollard coping) attachment while group II received single implant retained overdenture with a locator attachment. Marginal bone loss around implant of both groups were evaluated by digital radiography with Digora software. Measurements were taken at baseline, 3, 6 and 12 months after implant insertion. Independent t-test was used for comparison between groups while the comparison of within each group by time was carried out by one-way analysis of variance followed by post-hoc Tukey test. Results An acceptable range of bone loss in both groups with a statistically non-significant differences between both groups during the same follow up period was recorded. Bone loss values in both groups over time showed a statistically significant difference between 3 and 12 months and between 6 and 12 months values, however, there was no significance difference resulted from the comparison of 3 and 6 months values. Conclusion Bollard coping attachment is recommended to retain mandibular overdenture when using immediately loaded single implant. It was evidenced by less marginal bone loss around the implant when compared to those with conventional locator attachment during the same follow-up period.
