Summary
Severe periodontitis can cause significant bone loss. This study shows implant distraction devices effectively rebuild alveolar bone after tooth extraction, enabling prosthesis fitting.
Area of Science:
- Dental Implantology
- Periodontology
- Regenerative Medicine
Background:
- Severe periodontitis leads to alveolar bone loss, complicating dental implant placement.
- Traditional bone grafting methods can be invasive and time-consuming.
Purpose of the Study:
- To evaluate the efficacy of immediate implant distraction device insertion following tooth extraction in patients with severe periodontitis.
- To assess the potential of this technique for alveolar ridge reconstruction and subsequent prosthetic rehabilitation.
Main Methods:
- Seven patients with severe periodontitis and alveolar bone loss underwent tooth extraction.
- Immediate insertion of an implant distraction device was performed post-extraction.
- Distraction osteogenesis was utilized for bone lengthening, followed by bony healing.
- Dental implants were subsequently placed and a prosthesis was fitted.
Main Results:
- The implant distraction device facilitated successful alveolar bone distraction and healing in all seven patients.
- All patients were able to receive dental implants and have prostheses fitted after the procedure.
- No major complications were reported during the distraction or healing phases.
Conclusions:
- Immediate implant distraction device insertion is a viable and effective technique for reconstructing alveolar bone lost due to severe periodontitis.
- This method offers a predictable approach for achieving bone regeneration, enabling successful dental implant placement and restoration.
