Screw-Retained Implant Prosthesis (Easy Explanation)

A screw-retained implant prosthesis is a dental crown, bridge, or full-arch prosthesis that is secured to the implant using a screw instead of cement.

⸻

✨ Why It’s Used

1. Easy to Remove & Repair

The dentist can unscrew it anytime for cleaning, tightening, or repairs
→ No drilling → No damage to the prosthesis

2. No Cement Problems

No risk of cement left under the gums, which can cause infection or implant failure.

3. Better for Full-Arch Cases

Gives strong, stable support for All-on-4 / All-on-6 type prostheses.

🦷 How It Works
1. Implant is placed in bone
2. Abutment or prosthetic interface is attached
3. Crown/prosthesis is secured with a tiny screw
4. The screw access hole is filled with composite
