Influence of Roxolid Implant Material on the Implant Stability Implant Stability

Fourteen completely edentulous patients were selected to participate in this study. From the outpatient clinic of Prosthodontic Department, Faculty of Dentistry, Ain Shams University. After fabrication of complete denture for all patients, patients were randomly divided to: Group A: Seven patients were rehabilitated with implant retained maxillary overdenture where four Straumann BLX® implant were inserted opposed by mandibular complete denture. Group B: Seven patients were rehabilitated with implant retained maxillary overdenture where four conventional acid etched implants were inserted opposed by mandibular complete denture. After implant placement using surgical guide, smart peg and ostell device were used to measure the primary stability of the implant then cover screw was placed and after six weeks, secondary stability was measured for both groups. After four months, the second stage started in which exposure of the implant fixtures took place and pick up was carried out. Patients were recalled frequently for post-insertion inspection and adjustment.
