What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing two types of dental screws to help hold removable false teeth in place for people without lower teeth. It aims to see which screw design works better for stability and function. The screws are placed in the jawbone to act like roots for the dentures, making them more secure and improving quality of life.

Will I have to stop taking my current medications?

If you are currently taking chemotherapy, corticosteroids, blood thinners, or psychopharmacological drugs, you will need to stop these medications to participate in the trial.

Is the treatment using Nobel Biocare titanium dental implants generally safe for humans?

Titanium dental implants are generally considered safe, but there are some concerns about the release of titanium particles, which can cause inflammation and other reactions in the surrounding tissues. Studies have shown that these particles can lead to inflammatory responses and potential genotoxic effects, although these effects are not always significant.12345

How do Nobel Biocare titanium dental implants differ from other treatments for dental implants?

Nobel Biocare titanium dental implants are unique due to their use of titanium, which is known for its low elastic modulus, corrosion resistance, and minimal potential toxicity. These implants are designed to enhance osseointegration (the process by which the implant integrates with the bone), potentially leading to better stability and faster healing compared to other materials.678910

What data supports the effectiveness of the treatment Nobel Biocare titanium dental implants?

Research shows that Nobel Biocare dental implants have been used in various studies, with factors like implant location and radiotherapy affecting their success. While some studies report bone resorption (loss of bone), others focus on long-term outcomes and risk factors for implant failure, indicating mixed results.1112131415
