Situational Preference Between the Two Dental Implant Restorations

Cement Retention	Screw Retention	Studies
It can be adopted when a single unit is to be restored or when a short span restoration is required. It is assumed that screw torque and implant number can be optimized. In this case, screw retention is only adopted when the long axis of the implant is too parallel.	When full-arch implantation is required, the screw retained implantation reconstruction is preferred. It is because these are more complication as compared to short span ones’.	Makke et al20 Ferreiroa et al20
When the diameter crown is narrow, the use of screw can impact crown integrity.	The prostheses of the cantilevered are required to be screw implanted reconstruction as these structures required to undergone maintenance during the prosthesis’s lifetime.	Wang, Judge, and Bailey19 Crespi et al14
When the prospects for the occlusion surface prevails concerning the esthetics or the occlusal stability because of restorative material sealing, the cement retained implant reconstruction is preferred.	It is also preferred in a situation when the patient has high prospects of developing gingival recession. Since the implantation is less complicated, it can easily be removed or modified in case new conditions occur.	Ragauskaitė et al18 Ma and Fenton13
Cement restoration can be adopted for misaligned implant restoration.	The screw retained implant reconstruction is more preferred when the patient is expected to experience more tooth loss in the future.	Shadid and Sadaqa2
	This can be used for the removal of the excess cement, or when there is a strong prevalence of the technical or biological complications.	Shadid and Sadaqa2
