Fixed Dentures on Implants – All-on-4 and Bar-Supported Prostheses
Fixed dentures on implants provide a complete, stable, and aesthetic solution for edentulous patients.
The most common options are the All-on-4 system and the bar-retained overdenture, depending on the patient’s needs and jawbone condition.
All-on-4 System
The All-on-4 technique is an advanced fixed rehabilitation method that allows placement of a full-arch prosthesis supported by only four implants, often without the need for bone grafting.
Bar-Supported Prosthesis
For patients with limited bone volume or those seeking a more affordable fixed alternative, a bar-retained overdenture can be an excellent solution.
Key features:
- Typically involves 2 to 4 implants supporting a metal bar for additional strength and stability.
- Provides significantly greater retention than conventional removable dentures.
- Easy to maintain – the prosthesis can be fixed or semi-removable, allowing the dentist or patient to detach it for cleaning when necessary.
Choosing the Right Option
- All-on-4 – ideal for patients seeking a fully fixed, permanent solution without the need for removal.
- Bar-retained prosthesis – suited for patients wanting a more stable alternative to removable dentures but with the option of easy removal for hygiene.
Both solutions provide high-quality, functional, and aesthetic tooth replacement, and the best choice depends on the patient’s anatomy and the recommendation of the treating dentist.
