Custom cast post treatment on an implant platform in 2 patients

The use of implant-supported prostheses to replace missing natural teeth has become an accepted treatment approach in dentistry. Although implant prostheses have a high overall success rate, numerous complications have been reported, and the device sometimes fails. The biological complications associated with the use of the device include peri-implant radiolucency, peri-implantitis, and loss of osseointegration radiographically. Mechanical failure of implant components can manifest in the form of loosened screws, loss of retention, screw or fixture fracture, and porcelain or framework fracture.
