In dental implant restoration, available literature demonstrates the advantage of using tall abutments, with a change of diameter with respect to the implant and a conical internal connection in the abutment-implant gap. However, for multiple restorations, the abutment-prosthesis connection has not been studied in detail. The "multi-unit" systems, both standard and brand specific, have either a flat or butt joint or an cone. In any case, both are external connection systems. Recently, an internal-type abutment-prosthesis connection system has been developed. Although it is proving its usefulness in single restorations, its use in multiple restorations compared to traditional systems has not been studied.
Therefore, taking into account all of the above, the present study has the overall objective of analyzing marginal bone loss (MBL) and adaptation of soft tissues by comparing a multiple prosthesis system of the "external, flat" type versus an external system of the "internal, conical" type.
