PEEK Implant Supported Restoration Clinical Trial
Official title:
Assessment of Peri-Implant Tissues Surrounding PEEK and Porcelain Fused to Metal Superstructures in Posterior Region (Randomized Controlled Clinical Trial)
The purpose of this study is to evaluate the influence of two superstructure materials Porcelain Fused to Metal (PFM) and PEEK on peri- implant soft and hard tissue reaction clinically.
Nowadays the use of dental implants for restoring missing teeth has gained a wide acceptance,
due to its high success rate.
Dental implants differ from natural teeth in transmission of functional loads to the bone,
where natural teeth and their periodontal ligaments provide proprioception, early detection
of occlusal loads and have a shock-absorbing function. Sensitivity and mobility of natural
teeth cannot be duplicated in osseointegrated implants,1 therefore most of the forces are
concentrated at the crest of the ridge leading to different living reaction including bone
resorption and subsequent implant loss.
Minimizing the occlusal loads on osseointegrated implants through selection of a new
superstructure material that can absorb part of this excessive force could be believed to be
a determining factor in the long-term success of an implant treatment program.
Many restorative materials are used nowadays for construction of final restoration of implant
supported superstructures including porcelain fused to metal (PFM), all ceramic, zirconia,
hybrid ceramics, and polyetheretherketone (PEEK). PFM restorations are still considered as
the gold standard because of their excellent biocompatibility, consistent esthetics, superior
strength, and marginal adaptation. Recently, the use of new resilient superstructure material
like PEEK-based restoration on implant prosthetics could modify the occlusal forces with
subsequent cushioning during function.
