Biological concepts in preservation of crestal bone around implants
Biology has always been important in preserving crestal bone stability. It is connected to the idea of "1 abutment - 1 time", which has been circulating in the dental world for decades. It has been suggested that moving restorative procedures to the abutment level allows no additional abutment disconnection, which in turn, does not disturb the peri-implant seal and produces better bone levels. To achieve this, an intermediary multiunit abutment or CONNECT abutment (MIS) is used. A positive outcome is obvious already at an early stage of the treatment, as multiple disconnections of the healing abutment are inevitable. Furthermore, a 1-year follow-up provides an even better clinical picture, as no bone loss and no bone remodeling is seen. It can be concluded that the use of intermediary multiunit abutments significantly reduces crestal bone loss around subcrestally positioned implants.
