Zirconia-based composite customized healing abutments for healthier soft tissue around dental implants

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults needing delayed dental implants will receive either a direct zirconia-based composite customized healing abutment or a conventional composite customized healing abutment placed at the time of implant placement and will be followed for three months. Clinical outcomes include pink esthetic score and papilla index measured at baseline and at 1, 2 and 3 months, while peri-implant sulcus fluid will be sampled with Periopaper to measure IL-1β at two months as a biochemical inflammation marker. The trial enrolls systemically healthy adults aged 20–50 with adequate implant primary stability (ISQ ≥70), a thick soft-tissue phenotype, and no need for bone or soft-tissue augmentation, excluding smokers, pregnant or lactating women, and vulnerable groups. All procedures and follow-up visits are performed at the Faculty of Dentistry, Ain Shams University in Cairo.
