Comparison of Screw versus Cement Retained Fixed Implant Supported Reconstructions

Variable	Screw-Retained Fixed Implant	Cement-Retained Fixed Implant	Recommendation
Occlusion	✔	✔	Concerning stable and optimal occlusion, the screw-retained restoration can obtain the same results as that of cement-retained teeth. This highlights that occlusion is present on the crown and not on the channel filling material used in the screw.12,17
Esthetics	✔	✔	Esthetic success is not dependent on the use of a screw or cement-retained restoration. Both can be used to achieve the same esthetic result.14
Porcelain Fracture	✔		Even though screw causes the decline of the strength, the appropriate adjustments to the occlusion scheme and appropriate adjustment can be made better as compared to the cement retained.17,18
Interocclusal Space and Retention	✔		Due to the limitation of the interocclusal space, the screw retained implant reconstruction is required.13
Provisionalization And Gingival Molding	✔		Between the two, the screw-retained implant reconstruction has more advantages as compared to the cement retained. It is because it achieves better contours of the tissues, its health, and soft tissue transfer.13,18,20
Passivity		✔	Cement-retained implant reconstruction is fit for passivity based on its buffer of cement space. Since passivity pose a greater technical challenge in screw based on its discrepancies in dimension along with complication of the screws such as loosening or fatigue fracture.10,17
Biologic Complications		✔	The biological challenges are less in screw implant reconstruction as compared to the screw retained implantation. Moreover, the residue of the retention can cause microbial colonies as well as cause adverse effect on the tissues.8,15,16,18
Overall Complications, Retrievability, And Long-Term Treatment Planning	✔		Studies have revealed that prosthesis can be simplified using screw-retained implantation.20
