Comparing two ways to attach a lower denture to four implants
Part of Bones, joints & muscles, Hormones & metabolism clinical trials.
This trial tests two ways to attach a lower denture to four dental implants: using four small clips (locators) or a single bar that connects all four implants. The goal is to find which method is more stable and comfortable for people who are completely toothless in the lower jaw.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have been completely toothless (both upper and lower jaw) for at least one year.
- You have four dental implants placed in the front part of your lower jaw, between the side incisor and first premolar areas.
- Your upper denture is made with a special technique that gives it a tight fit and uses a certain tooth arrangement.
- The bone height in the front of your lower jaw, as seen on an X-ray, is between 15 and 25 mm.
- You are not a heavy smoker (more than 10 cigarettes a day) and do not abuse alcohol.
- You have been able to come back for check-ups for at least 10 years, with good X-ray records.

This study tests a new way to place four implants in your lower jaw to support a removable denture (overdenture) instead of a fixed bridge. The goal is to see if this guided approach works well and lasts over three years.
This study compares two ways to attach a lower denture to dental implants. It aims to find which method gives better fit and comfort for people who have lost all their teeth.
This trial tests different ways to attach a lower denture to dental implants. It aims to find which attachment type works best for people who need a stable, comfortable denture.
This trial compares two types of implant-supported dentures to see which one works better for people with no teeth. You will receive a set of dentures that click onto implants in your jaw, and the study will help you chew more comfortably.
This study compares two different types of attachments (MK1 and Clip) used to hold a lower denture in place with four dental implants. It looks at how they affect bacteria in the mouth, which may help in choosing the better attachment for better oral health.
This study compares two types of dental implants used to support a full set of lower teeth. It looks at how the jawbone reacts over time to help determine which implant design may be more stable.
