Volumetric Analysis of Ridge Preservation Using Bio-Oss^® Collagen: A Retrospective Cohort Study Based on CBCT and...

Area of Science:

• Dentistry
• Oral Surgery
• Regenerative Medicine

Background:

• Tooth loss leads to alveolar ridge resorption, impacting chewing and quality of life.
• Dental implants require sufficient bone volume for successful placement.
• Ridge preservation techniques minimize post-extraction bone loss, avoiding further augmentation.

Purpose of the Study:

• To evaluate the effectiveness of Bio-Oss® Collagen in preserving alveolar ridge volume after tooth extraction.
• To assess volume changes in molar and premolar extraction sockets treated with ridge preservation.

Main Methods:

• Retrospective study of 80 patients undergoing tooth extraction and ridge preservation with Bio-Oss® Collagen (2018-2022).
• Pre-extraction alveolar socket volume estimated from CBCT and panoramic radiographs.
• Post-extraction socket volume measured via CBCT after ridge preservation.

Main Results:

• Ridge preservation with Bio-Oss® Collagen resulted in an average bone volume loss of 3-18% post-extraction.
• Maxillary molar sites showed the highest resorption (approx. 18%), while maxillary premolar sites had the lowest (approx. 3%).
• Significant reduction in resorption compared to natural healing, with specific volumes detailed by tooth type and location.

Conclusions:

• Bio-Oss® Collagen is effective in reducing ridge resorption following tooth extraction.
• The material aids in maintaining alveolar bone volume, supporting future implantology.
• Location-specific resorption rates highlight the importance of tailored treatment approaches.
