The factors that should be considered as
determinants for increasing the OVD are the remaining
tooth structure, the space available for the restoration,
occlusal variables and aesthetics. Minimizing the
increase in OVD is useful to reduce the overall
complexity of the prosthodontic treatment. Increasing
OVD by more than 5 mm is rarely indicated. Furthermore,
increasing OVD is a safe procedure, and any
consequential signs and symptoms tend to be selflimiting.
The use of a removable splint to increase OVD
for TMD-free patients is not indicated as it might
generate signs and symptoms related to splint wearing
rather than OVD increase.
