While cementable restorations do provide strong retention, when interocclusal space is limited, screw-retained options might be more beneficial since they can be more easily adjusted and, thus, eliminate issues related to space constraints without compromising retention. In many cases, cementable restorations are chosen for their aesthetic benefits, as they can be designed without the visibility of screws, and this option would typically take precedence in scenarios where appearance is critical.

The potential for screw loosening and fractures tends to be higher in screw-retained designs due to the mechanical nature of screws. In contrast, cemented restorations do not utilize screws, thus providing an advantage in reducing complications associated with those mechanical components. Additionally, cementable restorations often result in better gingival health because they can provide more complete coverage of the abutment, reducing plaque accumulation and supporting healthier tissue.

Therefore, while cemented restorations possess several distinct advantages, the retention in scenarios with limited interocclus
