Screw Performance: An Important Factor in Implant Success
Central to reliable dental implant restoration is the dentist’s capacity to understand and appropriately manage prosthesis retention screws. In this respect, dentists have truly become modern-day oral engineers. Predictable therapeutic success requires an appreciation of screw-joint preload, screw-torque maintenance during function, and screw lubrication and its impact on preload, along with factors influencing the anticipated loss of preload over time and reliable mechanical generation of preload using the appropriate tools. In this issue of Prosthodontics Newsletter, we review some of the current literature detailing the application of prosthesis retention screws in successful implant dentistry.
