What side effects are associated with this type of intervention?

Implant-retained dentures, which involve securing dentures with one or two implants, are a common treatment for toothlessness. Known side effects of this treatment can include discomfort or pain at the implant site, infection, implant failure, and the need for maintenance of the dentures and prosthetic attachments. Additionally, there may be a risk of bone loss around the implant if not properly maintained. Overall, patient satisfaction is generally high, but individual experiences can vary based on factors such as age, health, and socioeconomic status.

What prior FDA approvals exist?

The FDA has approved various treatments for toothlessness, including implant-retained dentures, which are designed to improve the stability and comfort of dentures. These treatments involve the use of dental implants, which are surgically placed into the jawbone to provide a secure anchor for dentures. The clinical trial mentioned compares the efficacy of lower dentures retained by one or two implants, indicating that both single and multiple implant strategies are recognized and utilized in clinical practice. These implant-retained dentures have been shown to enhance patient satisfaction by improving the fit and function of dentures.

What other types of research exist?

Promising novel alternatives to implant-retained dentures for toothless patients in 2024 include: 1) Digital dentures, which utilize advanced 3D printing technology for a precise fit and faster production times. 2) Milled dentures, offering high accuracy and durability through computer-aided design and manufacturing (CAD/CAM). 3) Bioengineered dental implants, which are in development to use stem cells and tissue engineering for natural tooth regeneration. These alternatives aim to improve patient comfort, reduce treatment time, and enhance overall satisfaction.

Awards & highlights

Summary

This trial is testing if using one implant to hold lower dentures is as good as using two implants. It aims to see if patients are just as happy with one implant over time. The study will also check how well the implants last and how often they need maintenance.

Who is the study for?

This trial is for people who have no teeth and are currently using complete lower dentures that look good and work well. They must be able to consent, stay available for the study duration, speak English or have a translator, and be fit for dental implant surgery.

What is being tested?

The study tests patient satisfaction with lower dentures held by either one or two implants over five years. It will compare how satisfied patients feel, how long the implants last, and how often the dentures need maintenance.

What are the potential side effects?

Potential side effects may include discomfort at the implant site, swelling, bruising, bleeding during or after surgery; there might also be issues with denture fit and function requiring adjustments.

Other Research

Implant-retained dentures use dental implants to anchor the dentures securely in the mouth, providing mechanical retention and stability. This method involves placing one or two implants in the jawbone, which act as a stable foundation for the dentures. This approach significantly improves the comfort, chewing efficiency, and overall satisfaction for patients compared to traditional dentures, which can often be unstable and uncomfortable. The enhanced stability from implants helps in better distribution of biting forces, reducing the risk of sore spots and improving the patient's ability to eat and speak confidently.
