Solidex Screw Retained Crown and Bridge
Screw-retained restorations offer the convenience of being easily removed and repaired, if need be. For this restoration, the ceramic is directly fired onto the abutment and the resulting abutment-crown complex is screwed into the implant. Screw-retained restorations can be utilized only if screw access is favorable.
A screw-retained restoration may be fabricated if the screw access is favorable (long axis of the implant and screw access hole are located on the lingual of the incisal edge). First, the ceramic is directly fired onto the abutment and the abutment-crown complex can be easily screwed onto the implant. The possibility for retrieval or retightening and reassessing the abutment screw can be offered by this type of restoration.
The primary advantage of a screw-retained superstructure is the lower profile retention of the abutment system. Cemented prostheses require a vertical component of 5 mm or more to provide retention and resistance form. A crown height reduction of 2 mm may decrease the retention as much as 40% when the implant abutment is only 4 mm in diameter. The screw retained system is more resistant to removal forces than the cement abutment when the abutment height is less than 5 mm. The prosthesis should be screw retained if the crown height does not allow sufficient abutment height and surface for cementation.
Another advantage of screw-retained crowns is the absence of residual cement in the gingival crevice, which may cause irritation to the surrounding tissues and lead to increased plaque retention and inflammation, similar to an excess cement condition with crowns on natural teeth.
Easy to retrieve and repair
No residual cement in the peri-implant soft tissue
Restorations for insufficient occlusal space (at least 5mm of occlusal space is required)
