Outcome of Dental Implant Therapy in Patients Treated With Antiresorptive Medication

Observational Copenhagen University Hospital at Herlev · NCT04741906

This study is testing if dental implants can be safely placed in patients who have been on certain medications for bone health for a long time, and how well these implants work compared to those in healthy individuals.

What this trial studies

This study investigates the feasibility of dental implant insertion in patients who have been treated with high, adjuvant, or low doses of antiresorptive medication for over four years. The research aims to assess clinical and radiographic signs of osseointegration after 3-4 months, as well as the stability of the implants for abutment connection and their survival rates compared to healthy individuals after one year of prosthetic loading. The study will involve dental implant surgery and subsequent prosthetic treatment to evaluate outcomes.

Who should consider this trial

Good fit: Ideal candidates include patients with cancer or osteoporosis who have been on antiresorptive treatment and have sufficient local bone quality for implant insertion.

Not a fit: Patients with poor oral hygiene, significant comorbidities, or those with a poor prognosis may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a viable option for dental rehabilitation in patients with cancer or osteoporosis who are on antiresorptive therapy.

How similar studies have performed: Other studies have shown promising results in similar patient populations, indicating that this approach may be feasible.
