• Single and multi-unit implant restorations where retrievability is desired
• Areas with sufficient vertical space for screw channel and restoration
• Full-arch or All-on-4/All-on-X prosthetics requiring regular maintenance
• Situations where cement-retained crowns pose a risk of peri-implantitis
• Complex restorations requiring periodic removal (e.g., for hygiene, repairs, or adjustments)

• Aesthetic zones (anterior) where the screw-access hole may compromise appearance
• Cases with limited occlusal space preventing proper screw access
• Poor angulation of implants that precludes ideal screw-channel positioning (unless corrected with angled abutments)
• Patients with bruxism or high occlusal stress if the restoration design is not reinforced
• When the restorative team lacks experience in screw-retained protocols

• Implant must be accurately placed with proper angulation (preferably guided surgery)
• Use scan bodies or impression copings for accurate intraoral scanning or analog impressions
• A custom or stock abutment may be used in combination with screw-retained crown designs
• Occlusion must be carefully managed to prevent stress on the screw joint
• Ensure correct torqueing of the screw to manufacturer specifications to prevent loosening

 Screw-retained crowns are not cemented intraorally. They are secured directly to the implant or abutment with a fixation screw. 
However, in hybrid designs (e.g., screw-retained crowns cemented onto a custom abutment outside the mouth), minimal cement is used extraorally before screw placement.

• Screw-retained crowns offer easy retrievability for maintenance and hygiene
• The screw access hole is typically sealed with Teflon tape and composite resin after torqueing
• Available in zirconia, e.max, or porcelain-fused-to-metal, depending on case
• Custom abutments may be used to optimize emergence profile and angulation
• Proper torque (usually 25–35 Ncm) must be applied to avoid complications
• Recommended to check occlusion and screw stability periodically
