Abutment Loosening

As an important consequence, clinicians must keep in mind that a removed abutment is covered with a thin layer of living cells: if reinsertion of the same abutment is desired, then either great care must be taken to preserve the vitality of these retrieved cells, or the abutment must be thoroughly cleaned and sterilized before reinsertion. In order to preserve the vitality of the cells, one should avoid using chemical disinfection procedures for the abutment or desiccating the cells. It can rather be advised to thoroughly disinfect the abutment head before unscrewing , to keep the retrieved abutments in sterile saline, and to avoid mixing abutments from several implants within the same arch or patient.
