What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine how the shape of a dental implant-supported prosthesis affects bone health around the implants. Researchers are examining whether different shapes of the underside of these prostheses collect more plaque, potentially impacting bone levels. Participants must have had a full-arch dental implant in their upper jaw for at least a year and be in good health.

As an unphased trial, this study offers participants the chance to contribute to pioneering research that could enhance dental implant designs and outcomes.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, if you have uncontrolled chronic diseases or are immunocompromised, you may not be eligible to participate.

What prior data suggests that this method is safe for patients rehabilitated with full-arch implant-supported prosthesis?

Research has shown that full-arch implant-supported dentures are generally safe and well-tolerated by patients. Studies have found that about 95.9% of these implants and 97.0% of the dentures last without major issues for recipients.

While problems can occur, they are uncommon. Some studies have noted issues such as screws coming loose or ceramic material chipping, particularly in individuals who grind their teeth. However, these issues do not affect everyone and can often be resolved by dental professionals.

Overall, evidence suggests that full-arch implant-supported dentures are safe and reliable for most patients.12345

Why are researchers excited about this trial?

Researchers are excited about the full-arch implant-supported prosthesis because it offers a comprehensive solution for patients who need complete dental restoration. Unlike traditional dentures, which can be unstable and uncomfortable, this treatment is anchored securely by implants, providing a more stable and natural feel. This approach can significantly improve the quality of life for patients, offering better function and aesthetics. Additionally, it reduces the need for frequent adjustments and replacements that are common with conventional dentures.

What evidence suggests that the intaglio shape of full-arch implant-supported prosthesis is effective for maintaining marginal bone levels?

Research has shown that full-arch implant-supported dentures effectively replace teeth. Studies find a very low chance of implant loss, at just 0.64% in the first year and 1.85% over five years. In this trial, participants will receive rehabilitation with full-arch implant-supported prostheses. The All-on-4 method, a popular choice, simplifies the process by avoiding the need for additional bone. Clinical results are generally positive, with a high success rate of 97.8% for these dentures. Most recipients experience few problems and achieve successful long-term outcomes.678910
