The biomechanical response of the biological tissues to the extrinsic mechanical
stimulations in the perioprosthetic patient is the result of a dynamic adaptive equilibrium of a
hierarchically structured network, the nodes of which constitute, in a macroscopic level, the
severely reduced periodontium and the dental tissues. The model of the network is the
theoretical approach of describing the capability of the system to transmit, store and dissipate
energy through its components and, thus, the medium to foresee the properties of a single
nodal malfunction, which can start a global failure cascading in the system. Cascades follow a
threshold rule meaning that a node will change state only if exceed a given threshold. Insofar
as in advanced periodontal cases, the periodontium‘s integrity is severely compromised and
the dental tissues‘ function is non-physiological, the failure cascade initiation is considered to
be triggered with non expected distribution by different and lower threshold values. This
means that, in the perioprosthetic patient, the system experiences differently the mechanical
stimulation and a functional loading case may exert progressively increased tooth mobility as
an indicator of progressive periodontal tissue collapse. Thus, the prosthetic treatment of the
cantilever cross-arch fixed partial denture applied on the perioprosthetic patient aims at the
re-establishment of a stable system capable of capturing the collapse initiation along with the
safeguard of its own restorative integrity. The balance between, as indicated by clinical and
auxiliary theoretical studies, seems to be related to the restoration‘s metal framework design
and dimensioning, while, in case of balance inclination, the system suffers either from
fracture on the weakest areas of the metal framework‘s connectors or from the collapse of the
weakest distalmost abutment in terms of periodontal or dental complications.
