1 abutment - 1 time story. Truth or myth?
The idea of "1 abutment - 1 time" has been circulating in the dental world for decades.
It has been suggested that moving of restorative procedures to abutment level allows no additional abutment disconnection, which, in turn, does not disturb peri-implant seal and produces better bone levels. Logic dictates, that positive outcome should be obvious already at the early stage of the treatment, as multiple disconnections of healing abutment are inevitable.
However, there are no clinical studies, which directly compare this approach with implant level restorations, as a control group, therefore, there is no strong evidence of the benefit of abutment level approach.
