Abstract
In advanced perioprosthetic cases where the periodontium‘s integrity is severely
compromised and the dental barrier‘s function is extremely disrupted, the biomechanical
response to the extrinsic mechanical stimuli of the system including the prosthetic
restoration supported by the biological tissues is quite altered. The differentiated altered
experience of the functional loading due to the lowered periodontium‘s threshold along
with the apical shift of the system fulcrum due to the periodontium‘s structure reduction
require a modified design of the restoration‘s metal framework as a critical factor in the
system‘s survival in order to secure the expected longevity of both the restorative and
biological structures, capturing the failure initiation of either progressive tissular or
technical collapse. So, the purpose of the present study was to: a. analyze the way by
which the periodontium reacts to the developing forces and how its integrity is related to
the experience of the stress field on the perioprosthetic patient; b. determine the
parameters defining the tooth prognosis in the perioprosthetic patient and how the
restoration type is involved; c. report the clinical significance of tooth splinting by
cantilever cross arch fixed partial denture applied on the perioprosthetic patient and the
way it is related to the response of the reduced periodontium and finally d. investigate the
