Dental Implants for Mandibular Overdentures
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores two types of dental implants to determine which better secures dentures in individuals without lower teeth. Participants will receive either a parallel-sided or tapered-shaped titanium implant in the middle of their lower jaw. It targets those with full dentures on both the upper and lower jaws who can open their mouth at least 30 millimeters. This trial suits individuals who have no remaining teeth and are in good health without major ongoing medical treatments. As an unphased trial, it offers participants the chance to contribute to valuable research that could enhance dental care options.
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.
What prior data suggests that these dental implants are safe for supporting dentures?
Studies have shown that both straight and tapered titanium dental implants are generally safe. For straight implants, research indicates a survival rate of over 99% in the first year. However, tiny titanium particles might be released, potentially causing inflammation in some cases.
A five-year study on tapered implants showed a high survival rate and stable bone levels. Some patients experienced bone loss, with 14.8% losing more than 2 mm of bone after five years. Despite this, the implants did not show further problems over time.
Overall, both types of implants are well-tolerated by most people. However, like any medical procedure, there are risks. Discuss these with a healthcare provider before deciding to join a clinical trial.12345Why are researchers excited about this trial?
Researchers are excited about these dental implants because they offer new design options that could improve outcomes for those needing mandibular overdentures. Unlike traditional dental implants which often have a uniform shape, this trial explores both parallel-sided and tapered-shaped titanium implants. The parallel-sided implants could potentially provide more stability in the jaw, while the tapered implants might better mimic the natural shape of tooth roots, allowing for a snugger fit and possibly faster integration with the bone. These design variations might offer patients a more customized and effective solution compared to conventional options.
What evidence suggests that this trial's dental implants could be effective for supporting dentures in the edentulous mandible?
This trial will compare two types of Nobel Biocare titanium dental implants: parallel-sided and tapered-shaped. Studies have shown that both straight and tapered titanium dental implants by Nobel Biocare effectively support dentures. For straight implants, research indicates that more than 95% last for many years, demonstrating long-term success. Similarly, tapered implants are safe and reliable, with minimal bone loss over five years. Both types of implants feature a special TiUltra™ surface that helps form a strong seal with the gums, protecting the jawbone from bacteria. Overall, evidence supports their effectiveness in providing a stable base for dentures.12356
