What is the advantage of replacing a complete denture with a screw-retained implant-supported prosthesis?

  1. Esthetic improvement only
  2. Decreases the load on the mucosa only
  3. Lower cost
  4. Decrease bone loss
Show answer and explanation

Correct answer: D. Decrease bone loss

  • A. While esthetics may improve with implant-supported prostheses, the primary functional advantage is prevention of bone resorption.
  • B. While implants do reduce mucosal load, the more significant and better-supported advantage is prevention of bone loss.
  • C. Implant-supported prostheses are SIGNIFICANTLY MORE EXPENSIVE than conventional dentures — lower cost is not an advantage.
  • D. The PRIMARY advantage of replacing a conventional complete denture with implant-supported prosthesis is DECREASE IN BONE LOSS. Dental implants transmit occlusal forces directly to the bone through osseointegration, stimulating bone remodeling and PREVENTING the continuous alveolar ridge resorption that occurs with conventional dentures pressing on soft tissue.
