Screw-access marking: a technique to simplify retrieval of cement-retained implant prostheses

One of the commonly cited disadvantages of cement-retained implant prostheses is their inability to be retrievable. The screw-access marking technique discussed in this article allows for any clinician, at any time, to simply and predictably retrieve the cemented implant prosthesis. By applying a discrete, but easily recognizable, marking on the occlusal surface of the restoration, the entry point into the screw-access chamber can be precisely and safely created. The screw-access marking technique is efficient, effective, and widely applicable.
