Abstract

Vertical positioning of dental implants relative to the cementoenamel junction (CEJ) of the adjacent teeth is essential for maintaining peri-implant bone stability and long-term success. This retrospective study evaluated how the vertical distance from the CEJ affects peri-implant bone loss in patients who had implants positioned at various distances from the CEJ. Bone loss was evaluated using panoramic radiographs over a 2-year follow-up period, with additional consideration of factors such as smoking and diabetes. Implants positioned >4 mm away from the CEJ exhibited a higher mean bone loss; however, this difference was not significant. Smoking significantly influenced bone loss, whereas diabetes and jaw location had no significant effect. These results highlight the potential influence of vertical implant positioning on peri-implant bone health and highlight the importance of appropriate maintenance care to reduce bone loss and ensure long-term implant survival.
