Periodontally compromised adult patients may benefit from modified appliance designs for space closure. TMA T-loops of .016 × .022 and .017 × .025 cross sections, with angulations incorporated via...
An analytical evaluation of a new spring design for segmented space closure
Geometric nonlinearities Segmental spring Translational unit Anchorage unit Applied force Effective force Limit of activation Activator
2009/1/12
Contemporary segmented-arch space-closure springs require activation techniques that have the side effect of producing a significant amount of geometric nonlinearity. This nonlinearity makes these s...
Controlled Space Closure with a Statically Determinate Retraction System
Cantilever Orthodontic appliance Statically determinate retraction system
2008/12/26
We designed a variant of a cantilever spring, the statically determinate retraction system, and studied its mechanical characteristics. This novel system consisted of a single-force cantilever arm m...
