A two-piece dental implant comprising a replaceable thin titanium sleeve may be a new approach to re-osseointegration following peri-implant disease.

Bacteria initiated peri-implantitis can lead to bone destruction around a dental implant, modifying its surface and preventing re-osseointegration. Consequently, all available methods for treating periimplantitis have disappointing long-term results. Implant failure will lead to loss of the prosthetic reconstruction as well.

Trauma as a Cause for Hepatopathy in Newborn Göttingen Minipigs.

Routine husbandry procedures during animal toxicity studies can result in incidental pathological changes. We report on trauma-induced hepatopathy in newborn Göttingen minipigs. Sixty-four neonatal minipigs were allocated to 13- and 26-week treatment arms.
