Summary
This study shows Nobelpharma osseointegrated implants achieve high clinical success rates, particularly in the mandible (99.1%), meeting all oral implant success criteria when following Brånemark guidelines.
Area of Science:
- Oral surgery
- Biomaterials science
- Dental implantology
Background:
- Osseointegrated dental implants are crucial for oral rehabilitation.
- Long-term clinical outcomes of Nobelpharma implants require comprehensive evaluation.
Purpose of the Study:
- To assess the clinical success rates of Nobelpharma osseointegrated implants.
- To evaluate implant survival in various anatomical locations and patient conditions.
Main Methods:
- Retrospective multiclinic study of 8139 consecutively inserted implants.
- Follow-up periods ranged from five to eight years.
- Success defined by implant stability, absence of radiolucencies, and minimal bone loss.
Main Results:
- Mandibular implants achieved a 99.1% success rate over 5-8 years.
- Maxillary implants showed an 84.9% success rate over 5-7 years.
- Implants in irradiated/grafted mandibles had 100% success; irradiated maxilla had 81.3% success.
Conclusions:
- Nobelpharma osseointegrated implants demonstrate high clinical success when following Brånemark guidelines.
- Mandibular placement yields superior long-term outcomes compared to maxillary.
- Implants show promising results even in challenging conditions like irradiated bone.
