Radiographic Comparison of Crestal Bone Loss Around Two Implant Systems with Different Surface Roughness: A Retrospective Study

Background and Aim: This retrospective study aimed to investigate the effects of surface roughness and implant body design on the amount of crestal bone loss around implant. Materials and Methods: In this retrospective study, dental records of 87 patients who received 139 implants were evaluated. The ITI group received 63 implants with moderate roughness, while the DIO group received 76 implan...

Influence of two different machined-collar heights on crestal bone loss.

PURPOSE The purpose of this trial was to evaluate crestal bone level changes radiographically in a standardized fashion over a period of 12 months in humans for implants with a 0.7-mm machined collar (implant type A) versus type B implants with a 1.5-mm machined collar. MATERIALS AND METHODS Twenty-five patients with multiple missing teeth in posterior sectors were randomly assigned to one of...

Peri-Implant Crestal Bone Loss: A Putative Mechanism

Purpose. The immunological mechanisms of peri-implant crestal bone loss have, hitherto, not been elucidated. We hypothesized that bacterial products from the microgap cause upregulation of cytokines in otherwise healthy peri-implant cells, which results in osteoclast formation and, ultimately, in bone resorption. Materials and Methods. We used RT-PCR and ELISA to assay mediators of osteoclastog...
