ClinConnect Summary
This clinical trial is examining how dental implants can experience bone loss over time, particularly focusing on the area around the upper part of the implant where it connects to the tooth restoration. Researchers want to understand the differences in bone loss between two types of dental implants: those with a conical connection and those with an internal hexagonal connection. They believe that implants with the hexagonal connection might lead to more bone loss due to higher levels of harmful bacteria and inflammation in the area around the implant.
To be eligible for this study, participants must have one missing tooth in the back of their mouth (either a premolar or molar) and have both neighboring teeth present. However, certain health conditions, such as uncontrolled diabetes, autoimmune diseases, or severe infections, may exclude someone from participating. If you join the study, you’ll be closely monitored over time for changes in bone levels and signs of inflammation or bacterial infection. This research aims to improve how dental implants are used and help prevent bone loss, ultimately leading to better dental health outcomes for patients.
