Comparing patient satisfaction with different dental implant frameworks

Patient Satisfaction and Oral Healthy Related Quality of Life of Polyetherketoneketone and Metal Framework for All-on-four Implant Supported Fixed Detachable Prosthesis: A Crossover Study.

Observational Mansoura University · NCT05904756

This study is testing whether people who get dental implants feel more satisfied and have a better quality of life with either plastic or metal frameworks.

What this trial studies

This observational study aims to evaluate patient satisfaction and oral health-related quality of life (OHRQL) in individuals receiving dental implants with either polyetherketoneketone (PEKK) or metal frameworks. Ten completely edentulous patients aged 50-60 will participate, receiving a complete denture followed by an All-on-4 implant procedure. After a three-month adaptation period, patients will be assessed for satisfaction and quality of life before switching to the alternative framework for another three months. This crossover design allows for direct comparison of the two materials within the same individuals.

Who should consider this trial

Good fit: Ideal candidates are completely edentulous individuals aged 50-60 with sufficient restorative space and healthy oral conditions.

Not a fit: Patients with contraindications for implant surgery, such as those with bleeding disorders or metabolic disorders affecting osseointegration, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help identify which framework material provides better patient satisfaction and quality of life for dental implant recipients.

How similar studies have performed: While studies comparing different dental implant materials exist, this specific crossover approach focusing on PEKK versus metal frameworks is relatively novel.
