Objectives The aim of this study is to investigate the performance and fracture resistance of
different CAD/CAM ceramic and composite materials as implant-or tooth-supported single …

Background. The screw-retrievable cement-retained (SRCR) design combines the benefits
of both screw-and cement-retained implant-supported restorations. This concept has …

Objective To evaluate the effect of screw access hole design on the fracture resistance of
cement‐retained implant‐supported zirconia‐based restorations with screw access holes …

The present study aimed to evaluate the impact of the existence of an abutment screw-
access hole and the filling effects on the fatigue mechanical behavior of a luted lithium …

Aim: To compare fracture resistance between the cement-retained (CR), screw-retained
(SR), and combined cement-and screw-retained (CCSR) metal-ceramic (MC) implant …

Statement of problem Whether the presence of a screw access channel on the occlusal
surface of a lithium disilicate cement-retained single tooth implant restoration reduces its …

Purpose: To investigate the effect (s) of screw-access hole (SAH) in different diameters on
the cement-retained implant prosthodontic systems and surrounding cortical bones …

This prospective study was undertaken to evaluate the clinical usefulness of a newly
developed one-piece, screw-free, and micro-locking implant system, which was designed to …

Background Screw retained implant prostheses seem to be an efficient restorative method to
prevent peri-implantitis caused by cement excess around the abutment. The drawback of the …

Statement of problem When a cement-retained lithium disilicate crown needs to be removed,
perforation is needed to reach the abutment screw. How this process affects its strength is …
