A tissue or structure wholly or partly beneath the surface.

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.
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.

In our next composition of the inhomogeneous domain we set the periodic alternating thin layers of two substructures of "soft" and "intermediate" materials with one thin layer of "hard" material d = 30[DELTA]x.
Modelling macroscopic mechanical properties of materials in relation to their substructure is a longstanding problem in materials science [3].
The development of new materials as well as the optimization of classical materials requires modelling, more closely related to the substructure of the materials under consideration.
In order to model the mechanical behaviour of such a variety of heterogeneous materials, the substructure has to be simplified.
Numerical simulations were performed for three different lengths of a pulse: [lambda] = 30[DELTA]x, 90[DELTA]x and 180[DELTA]x for each analysed substructure composition.
We consider several substructure compositions within the inhomogeneous domain (Fig.
The results of propagation of the pulses through different compositions of the substructure are compared with the behaviour of the reference pulses, the propagation of which is calculated for a homogeneous bar of the "hard" material.
2) leads to a considerable response of the pulses to the substructure (Fig.
The bar contains here a more complex substructure consisting of a succession of regions that involve two thin layers of soft material separated by a similar layer of hard material (d = 30[DELTA]x for each thin layer as in case (b)) alternating with regions equivalent to a thicker layer (d = 90[DELTA]x) of the "hard" bar material as in case (a).
The reaction of the signal to the presence of substructure is even more complicated if the regions containing three thin layers of different material are formed from materials of different properties.
