Screw-retained bridges – pressed-over or veneered? The implant restoration for the edentulous jaw
Either – or? Why not both? If the individual layering technique is combined with the press technique, esthetic restorations can be fabricated in an efficient way.
When producing implant-supported bridges, the occlusal screw retention is an increasingly important factor. Due to the restorative possibilities provided by the material zirconium oxide and the development of CAD/CAM systems, this type of restoration is already very common. Occlusally screw-retained bridges allow the dentist to access the connection point between the superstructure and the implant. This enables for example, the peri-implant situation or the fit of the abutment to be checked. As a result, we can predict good results over a longer period of time. In addition, the process of inserting the restoration is made easier, and regular monitoring of the superstructure is possible.
Basically, the way an implant restoration is fabricated, in terms of the angle of inclination of the implants, the type of connection elements and the processing method used, depends on which technique is selected for the esthetical veneer.
Quite often, a cemented restoration is chosen when the screw channel opening for securing the abutment to the implant is located on the vestibular side – where it is visible. There is [...]
