Immediate dental root implants from synthetic dense calcium hydroxylapatite

Area of Science:

• Biomaterials Science
• Dental Implantology
• Regenerative Medicine

Background:

• Tooth extraction often leads to alveolar ridge resorption.
• Preserving alveolar bone height is crucial for successful dental restorations.
• Traditional implants may require bone grafting procedures.

Purpose of the Study:

• To describe root implants made of calcium hydroxylapatite (CHA).
• To evaluate CHA implants for immediate post-extraction placement.
• To assess their potential for alveolar ridge preservation and denture support.

Main Methods:

• Fabrication of root implants using densely sintered or hot-pressed calcium hydroxylapatite.
• Immediate implantation following natural tooth extraction.
• Evaluation of ridge preservation and implant stability for prosthetic rehabilitation.

Main Results:

• Calcium hydroxylapatite (CHA) root implants can be placed immediately after extraction.
• Implants demonstrated potential in maintaining alveolar ridge volume.
• CHA implants provided stable anchoring for post and core placements.

Conclusions:

• Calcium hydroxylapatite (CHA) root implants are a viable option for immediate post-extraction placement.
• They offer benefits in preserving alveolar ridge structure.
• CHA implants show promise as anchors for fixed partial dentures.
