substructure [sub´struk-chur]
the underlying or supporting portion of an organ or appliance.
substructure,
n a structure built to serve as a base or foundation for another structure.
substructure, implant (implant denture substructure),
n 1. a skeletal frame of inert material that fits on the bone under the mucoperiosteum.
2. the metal framework that is embedded beneath the soft tissues in con-tact with the bone for the purpose of supporting an implant superstructure.
2. the metal framework that is embedded beneath the soft tissues in con-tact with the bone for the purpose of supporting an implant superstructure.
substructure, implant, abutment,
n the portion of the implant that extends from the surface of the mucosa into the oral cavity for the retention of crowns, bridges, or superstructure bearing the teeth of the denture.
substructure, implant, auxiliary rest,
n a small metal protrusion through the mucosa connected to the labial or buccal and lingual (peripheral) frame to furnish additional support for the superstructure between the abutments.
substructure, implant, interspace,
n a space between the primary and secondary struts that allows infiltration of tissue.
substructure, implant, neck (implant post, implant substructure, post),
n the constriction that connects the implant frame with the implant abutment.
substructure, implant, part,
n the root section shaped in the form of a wire loop. This part of the substructure sinks into the alveolar socket or sockets after the extraction of one or two remaining anterior teeth. Newly formed bone tissue grows through the loop and firmly affixes the implant.
substructure, implant, peripheral frame,
n the labial, buccal, lingual, and distal outline of the frame.
substructure, implant, post,
n See substructure, implant, neck.
substructure, implant, primary struts,
n the main traverse struts that connect the implant necks or posts with the peripheral frame.
substructure, implant, secondary struts,
n the additional smaller transverse, diagonal, and longitudinal struts that are added when necessary to give additional strength and rigidity to the implant, increase the area of bone support, and afford additional intermeshing of the mucoperiosteal tissue.
