Completely Edentulous Patients Clinical Trial
Official title:
Prosthesis and Implant Survival in Immediately Loaded Full Arch Restorations Using Fiber Reinforced Versus Non-reinforced Temporary Frameworks: A Randomized Clinical Trial
In immediate loading of implants of completely edentulous patients, the most common
post-surgical complication following the surgery noted in the dental literature is fracture
of the provisional restoration with rates ranging from 4.17% to 41%. Most of these fractures
occur because polymethyl methacrylate (PMMA) materials are inadequate and have low rigidity
to withstand extended periods of heavy occlusal use.
Fractures of full arch provisional restorations during healing are concerning, because they
eliminate cross-arch stabilization and disrupt stress distribution patterns which might
jeopardize implant osseointegration affecting the survival rates for implants. Therefore, it
is important to look for another material that has higher rigidity than PMMA and can
withstand masticatory forces for extended periods without fractures or load concentration on
the implants during the osseointegration period.
