Repeated implant analog reuse effect on dimensional accuracy and marginal gap with abutments - An in vitro study

The use of same implant analog multiple times affects their accuracy and the distance between the implant and abutment. Hence, 30 titanium analogs were grouped according to how many patients had worn them before (0, 5 and 10). Stereomicroscopy and digital calipers were used to measure both the marginal gap and dimensional changes. The evidence points to clearly increased differences and dimensional losses as the parts were used and reused (p < 0.001).
