What this trial studies

This clinical trial aims to assess the efficacy of the Nobel Parallel CC implant combined with the on1 abutment compared to traditional healing caps in posterior teeth. It is a prospective clinical study that will follow participants for five years, with evaluations including panoramic imaging to measure marginal bone levels and clinical assessments of implant conditions and patient satisfaction. The study will involve 80 patients, with 40 receiving the new on1 abutment and 40 receiving a conventional healing cap. The goal is to determine the clinical outcomes and benefits of the new abutment design over time.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old who require a single dental implant in the posterior region without any medical contraindications.

Not a fit: Patients with uncontrolled systemic diseases, severe malocclusion, or those who smoke heavily may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved outcomes and satisfaction for patients receiving dental implants.

How similar studies have performed: While there are few clinical studies on the on1 abutment, the approach of using a fixed abutment during surgery is relatively novel and has not been extensively tested.
