Summary
This study examined failing hollow implants, finding bone loss limited to the top portion. Despite some resorption, the hollow areas were mostly filled with bone, suggesting treatment potential.
Area of Science:
- Dental Implantology
- Biomaterials Science
- Oral Surgery
Background:
- Evaluating the outcomes of failing hollow dental implants is crucial for understanding treatment limitations.
- Radiologic, histologic, and histometric analyses provide a comprehensive assessment of implant integration and failure modes.
Observation:
- Failing hollow implants exhibited vertical bone loss extending to the implant's hollow section on radiographs.
- Histologic examination revealed bone infill within the hollow portions, with inflammatory granulation tissue and minor resorption at the coronal aspect.
Findings:
- Histometric analysis showed high bone contact percentages (84.3%–93.1%) but variable bone filling within the hollow portions (33.8%–50.5%).
- The destructive changes observed were localized to the coronal regions of the implants.
Implications:
- The findings suggest that failing hollow implants may retain potential for successful treatment due to the limited extent of bone destruction.
- Further research into managing coronal bone loss and inflammation in such cases is warranted.
