objectives: fracture strength is an important factor influencing the clinical long-term success of implant-supported prostheses especially in high stress situations like excessive crown height space (chs). the purpose of this study was to compare the fracture strength of implant-supported fixed partial dentures (fpds) with excessive crown height, fabricated from three different materials. mater...

Carbon-fiber-reinforced polyetheretherketone implants offer several benefits over traditional metal implants. Their radiolucent property permits improved, artifact-free radiographic imaging. Their lower modulus of elasticity better matches that of bone. Their fatigue strength is greater than most metal implants. This article reviews the use of these implants in orthopedic surgery, including tre...

Implant repair is a common means to restore the normal function of hard tissues (bone or teeth). At present, commonly and potentially used implant materials include titanium alloy (Ti), zirconia (Zr), polyetheretherketone (PEEK), 30% carbon fiber reinforced PEEK (CFR-PEEK). This study compares their physicochemical biological properties, including surface morphology, contact angle, nano hardnes...

This study describes an unusual case of mandibular asymmetry after fibula free flap reconstruction in a young man following major facial trauma that was corrected using a custom-made polyetheretherketone prosthesis. There is little information in the literature on the use of alloplasts to correct mandibular asymmetry as interest in 'aesthetic re-modelling' has traditionally focused on nasal, zy...

Carbon fiber (CF)/Polyetheretherketone (PEEK) laminates are emerging as a potential material for aero structural applications thereby offering tough competition to the traditional FRPs. The additional advantages like high production...
