Evaluating a new dental implant abutment for posterior teeth

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

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.
