ClinConnect Summary

This clinical trial is studying a new type of healing part used during dental implant procedures for people missing a tooth. Specifically, it is looking at whether a healing abutment made with a special material called zirconia-based composite helps the soft tissue (the gums around the implant) heal better, compared to the usual composite material. Researchers want to see if this zirconia-based material causes less inflammation and is more compatible with the body, which could lead to better results after implant surgery.

People who might join this study are adults aged 20 to 50 who are missing a tooth and are healthy overall, with good oral hygiene, no smoking habits, and no pregnancy. They should have enough healthy teeth nearby and have a mouth opening wide enough for the procedure. During the study, participants will have a thorough dental exam and cleaning before the implant surgery. During surgery, the implant will be placed, and one of the two types of customized healing abutments will be attached. Afterward, participants will visit the dental office several times over three months to check on healing and tissue health. This study is still looking for volunteers and aims to find better ways to support healing around dental implants.
