ClinConnect Summary
This clinical trial is looking to find out if using different types of dental implants affects how accurately they can be placed right after a tooth is removed. Specifically, the study will compare deep-threaded implants to regular-threaded implants in patients who need to have one or more teeth extracted. The researchers will use a special technique called dynamic navigation to help guide the implant placement. They hope to understand if there is a difference in how well these two types of implants are placed.
To participate in this trial, you may be eligible if you have teeth that need to be removed and don't have serious health issues that could complicate the procedure. You should also not smoke heavily or have untreated gum disease. If you join, you can expect to have your implant placed immediately after your tooth is extracted, and your progress will be monitored closely. This trial is not yet recruiting participants, so there’s no need to sign up just yet, but it could be a great opportunity for those who qualify!
