The design of the implants placed in this study. A) Conventional-sized implant with EH prosthetic connection; B) Conventional-sized implant with MT prosthetic connection; C) Short-sized implant (5 mm) with EH prosthetic connection; D) Short-sized implant (6 mm) with EH prosthetic connection; E) Short-sized implant (5 mm) with MT prosthetic connection; F) Short-sized implant (6 mm) with MT prosthetic connection. Note that conventional implants, in addition to the differences in platform type, present important differences in the region of the implant neck where the EH type implant has micro-threads and a smooth collar whereas conventional implants with MT connection have a neck without micro-threads with microroughness collar. Short implants have a similar configuration except for the type of prosthetic connection.
