New studies confirm effectiveness of dental implants
BASEL, Switzerland: Two large international studies have added new clinical evidence to the reliability of Straumann’s dental implant systems. Researchers from various countries evaluated more than 100,000 bone-level implants from the specialist in implant, restorative and regenerative dentistry, and reported high implant survival rates with practically no bone loss around the implants.
In the first study, a team of researchers at 11 clinical centres in Europe, Australia and the US compared outcomes in 106 patients who received one dental implant placed using one of two different surgical approaches. The first approach was submerged implant placement, in which the implant is covered with mucosa during healing, and the second approach was transmucosal implant placement, in which part of the implant is exposed, thus avoiding a second surgical procedure.
After a follow-up period of three years, they observed that only one implant was lost, yielding survival rates of 98.1 per cent and 100 per cent for the transmucosal group and submerged group, respectively. In addition, they found that the bone level decreased by only 0.6 mm in the first group and by less than 0.7 mm in the second group.
The second study involved dentists from Europe and the US, who had to follow the manufacturer’s guidelines but were able to use the implant as they would in normal daily practice. In total, 908 implants in 538 patients treated at more than 100 dental practices were evaluated. According to Straumann, the study found an implant survival rate of 98.5 per cent and a very stable bone level in the majority of cases after one year.
Previous studies of other implants showed an overall implant survival rate of 95.5 per cent one year after placement. Thus, the survival rates reported in the present studies are significantly higher than those documented in the literature.
