unsplinted

— Most of the separated attachments need more prosthetic maintenance;[ 52 65 ] but for others, the frequency of technical complications/repairs per patient was higher around bar than ball attachments,[ 52 66 67 ] with an increased failure rate for the cantilevered extended bars.[ 68 ] Meanwhile, no difference was seen in the implant survival rate among splinted and unsplinted schemes.[ 69 70 ] Recent studies sought to compare the incidence of mechanical complications of the Locator attachments with that of the commonly used overdenture attachment systems.
