title: Radiographic comparison of periimplant bone resorption and assessment of survival rates of 2 implant systems: a 10-year prospective multicenter study.
abstract: OBJECTIVE
  The aim of this multicenter human clinical trial was to radiographically evaluate the marginal bone loss and to assess implant survival rate in patients treated using 2 different implant systems (Bio-Plant and Tuber-Plant) after 10 years of loading.
  
  
  METHODS
  Ninety-seven patients were selected, and 160 implants were inserted (72 Bio-Plant and 88 Tuber-Plant). Ten years later, 20 patients were lost at follow-up and 77 patients (126 implants; 67 Bio-Plant and 59 Tuber-Plant) were recalled. After 10-year, the periimplant bone resorption was significantly lower (P = 0.0039) for Tuber-Plant (0.74 ± 0.12 mm) than for Bio-Plant (1.31 ± 0.09 mm). The cumulative survival rate was 99.11%.
  
  
  CONCLUSIONS
  Both implant systems demonstrated to be suitable for a long-term successful rehabilitation because of stable marginal bone levels and high survival rates after 10 years of functional loading.
