Summary

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.

Conditions

  • PEEK Implant Supported Restoration

Interventions

OTHER

PEEK crown

The main concern of dental implants is their lack of elasticity, therefore with the use of PFM, all ceramic or zirconia crowns; the load is directly transferred to bone. That is why up till now researchers are in quest of different materials to enhance soft and hard tissue reaction around implant supported restorations. Recently the use of PEEK as a final restoration on dental implants has wide acceptance, due to its excellent biocompatibility and exceptional physical and chemical properties regarding toughness, hardness and elasticity. In term of load cushioning capacity of the prosthetic elements, PEEK has a comparable modulus of elasticity (4GPa) to that of bone (4.2GPa). Thus, the bone could allow bone stimulation favoring its remodeling without overloading.

OTHER

PFM Crown

Although metal free restorations are gained popularity recently, PFM restorations, whether they are tooth-supported or implant-supported are still considered as the gold standard due to their excellent biocompatibility, consistent esthetics, superior strength, and marginal adaptation.2 PFM restorations are also considered durable and long-lasting
