Screw-Retained vs Cement-Retained

Implant prostheses are commonly restored using screw-retained or cement-retained techniques. Both options are clinically proven and widely used; the choice depends on esthetics, retrievability, angulation, and long-term maintenance requirements.

Screw-retained implant prostheses are directly secured to the implant using a fixation screw. This design allows easy removal of the crown for maintenance, repairs, or hygiene procedures. It is especially preferred in cases where retrievability and peri-implant tissue health are critical.

Cement-retained implant prostheses are luted onto an abutment using dental cement, closely resembling conventional crown placement. They offer superior esthetics due to the absence of a screw access hole and are often chosen for anterior restorations.

Cement-Retained Prosthesis – Key Benefits

  1. Superior Esthetics: No visible screw access hole, ideal for visible areas
  2. Simpler Clinical Procedure: Familiar workflow similar to traditional crowns
  3. Better Passive Fit: Cement compensates for minor angulation discrepancies
  4. Cost-Effective Option: Often lower laboratory and component costs
1. MLS crowns and bridges are made of a particle size of 3–14 μm. This combined with very fine point laser (0.1 mm) results in a density of 99.9 %, resulting in stronger copings

2. The densely sintered crowns have practically no voids.

3. The process results in highly accurate, well detailed restorations.

4. Coping thickness, pontic design and cement thickness can all be standardized with this method.

5. Laser sintering is a computer-controlled, precise process that ensures consistent work quality.
 
Conclusion:

Both screw-retained and cement-retained implant prostheses offer excellent clinical success. Screw-retained restorations are preferred for retrievability and long-term maintenance, while cement-retained restorations are chosen for esthetics and simplicity. The final selection should be based on clinical indication, implant position, and patient-specific requirements.
