ClinConnect Summary

This clinical trial is studying two different types of materials used in dental implants: a reinforced resin and a solid zirconia. The goal is to see how these materials affect the strength of biting and any changes in the bone around the implants. This research is important because it can help improve dental solutions for patients who need artificial teeth.

To be eligible for this trial, participants should be adults aged 30 to 60 who have specific dental conditions, such as missing teeth in the lower jaw but have healthy gums and bones. It's also essential that they can attend follow-up visits and are in good health overall. If someone has certain medical conditions, like Parkinson's disease or is a heavy smoker, they may not qualify. Participants can expect to receive dental implants and will be monitored over time to assess their progress and any changes related to the materials used. This study is currently looking for volunteers to join and contribute to improving dental health options.
